Harry Potter and the Methods of Rationality/WMG

Dementors End Up Being Analogous To Cryonics
The Dementors were made by some precursor wizards and they have the kiss to preserve people after death, so they could be resurrected in the case of a magical singularity. Since they were so important, they were made very sturdy, almost but not quite impossible to destroy.
 * Is that necessary? They have time machines. In fact, that should be a clue to Harry that the afterlife exists, since remote imprints can be made of people's minds.
 * There are limits to how long you can preserve a wizard regardless. Remember, they're doing everything they can with magic just like we do what we can with medicine, end even with all that magic, I don't remember anybody over 200, except Flamell. Maybe the dementors, when they suck out the soul (or whatever), actually store it, waiting for some sort of new body.
 * Dementors represent Death. Through some law of magic they are a shadow that Death casts into the world. It doesn't take much reading about Eliezer Yudkowsky to come quickly to the conclusion that Death is his least favorite thing, and cryonics is how he fights it. It is rather doubtful that he's going to have the two be the same thing.

Harry's Odd sleep Cycle Means something
Perhaps it is a clue about his dark side. Maybe it has something to do with Quirrells zombie mode.
 * It's actually a real thing, and probably no more than an excuse to give Harry his time-turner.
 * I agree it's probably just an excuse to give him a time turner. Still, I find it easier to believe that they'd give him one when he really required it to function properly (because of a condition that really exists) than I would if he just got one randomly, like happens in some other fan fictions.

The Horcruxes are lost in the four elements and in space.
In Chapter 46, Quirrell asks Harry "if you wanted to lose something where no one would ever find it again, where would you put it ?". Harry suggests putting it in the molten core of Earth, one kilometer in the ground, at the bottom of the ocean, in the stratosphere or in space. As we already know Pioneer is Horcruxed, it seems Quirrell did the same with the four other suggestions, which makes sense with the end of the dialogue.

Lucius Malfoy thinks Harry is Voldemort.
Reread the conversation in chapter 38 particularly this part: "When I read your response to Professor Quirrell's little speech," said the white-haired man, and chuckled grimly. "I was puzzled, at first, for it seemed not in your own interest; it took me days to understand whose interest was being served, and then it all finally became clear. And it is also obvious that you are weak, in some ways if not others."

Harry is Voldemort.

 * Lucius Malfoy is right. Where would be the best place to hide? Where even you don't know where you're hidden. Harry James Potter-Evans-Verres is Voldemort, body-swapped and obliviated. They'd _never_ see it coming! It would certainly explain where Voldemort is if he's not in Quirrel's (non-existent in this canon, by the way) turban. Fight Club Ending Ahoy!
 * This allows Voldemort to fulfill that pesky prophesy and lay low while preparing his take-over-the-world bid from another angle and fulfills the author's promise that no one would hold the idiot ball. Also it may have made Voldemort more compatible with Harry Potter's infant body. In Chapter 46, Quirrell says, "One can never quite disentangle the mind from the body it wears."
 * In Chapter 43, Quirrell says, "Our worst memories can only grow worse as we grow older." This may be a hint about What's Wrong With HJPEV, namely, his obliviated memories of his life as Tom Riddle's have made him very capable with disassociation, prone to cold rage, vulnerable to dementors, and exceptionally good at broomstick riding.
 * That's why the rememberall lit up like a sun. He had forgotten an entire lifetime.
 * However, as obliviation isn't reversible (as far as we know), isn't it more likely he has used a Pensieve with Bellatrix's assistance?
 * Nope, Jossed. McGonagall says that if Remembralls lit up for people who had been Memory-Charmed, courts would use them and the purebloods' trick of Obliviating themselves wouldn't work.
 * It is established early on (Chapter 7?) that Obliviate charms are used much more flippantly in this universe; Draco states that people place offending memories in Pensieves, Obliviate themselves and recover the memories after the event.
 * This was all done with the assistance of Bellatrix Black who then left the scene and travelled to some 'safe' location before obliviating herself. After she had obliviated herself, she attempted to return Voldemort's wand to him, but of course could not find him and heard he was destroyed by an infant he had, apparently, confronted alone. She then stored his wand under his father's gravestone.
 * This answers the question of how Bella got the wand without knowing what happened to Voldemort when Voldemort needed his wand to use the Killing Curse on James and Lily Potter. We find out about Bellatrix and the wand in Chapter 53, "I hid it in the graveyard, my lord, before I left," even though she doesn't know what happened to him.
 * The conversation with Lucius Malfoy shows us that Malfoy has figured out at least part of the Dark Lord's JC Two-Step, but there are also hints form the Quibbler.
 * HJPEV is 65 years old because he is Voldemort. Since Lucius knows this, Lucius has a very different understanding of the line, "I prefer to deal with the part of House Malfoy that's my own age." than HJPEV does.
 * Blatant early foreshadowing in Chapter 5 if this is the case:
 * Harry considered the question. Was he really Harry Potter? "I only know what other people have told me," Harry said. "It's not like I remember being born." His hand brushed his forehead. "I've had this scar as long as I remember, and I've been told my name was Harry Potter as long as I remember.
 * If Harry James Potter-Evans-Verres is Voldemort, who or what is Quirrell?
 * Quirrell is Quirrell.
 * We have Word of God that Quirrell is Voldemort. But some of the comments he's made make Voldemort's actions make no sense for that character: anyone who can see the ethical way in which, say, Bellatrix is innocent, would probably have a hard time doing a lot of the stuff Voldemort did. So where did the really dark, nasty stuff go? It went into Harry. And proceeded to undergo ten years of being raised by decent people, a piece of perspective that Tom Riddle completely lacked, and finding Science, and such. Which means that we now have two active Voldemorts on the board: Harry, who got a large chunk of the evil but is learning how to get better; and Quirrell, who is still cunning, manipulative, power-hungry and somewhat evil but just not as horrible as he used to be... and is actively mentoring his other self. Watch this space; they're very well primed for taking over the world.
 * I know it's not really important, but if Harry was Voldemort, then wouln't his full name (because the one he has right now is kind of important for the wizarding world, so they wouldn't just let him change it) be "Harry James Tom Marvolo Potter-Evans-Verres-Ridle"? Or would it be "Tom Marvolo Harry James Riddle-Potter-Evans-Verres"? Or any other combination?

Quirrell is a basilisk.
So if HJPEV is Voldemort, then who is the antagonist?
 * What we know for sure about Quirrell is:
 * He is not a good person; we know that much because he killed Rita Skeeter and the author likely killed off Skeeter specifically so we would know that Quirrell is not a good person.
 * He is amazingly powerful and either very intelligent and clever or in possession of very dependable foreknowledge.
 * He has no history before he applied at Hogwarts. - this is no longer true (maybe)
 * He has some kind of crazy-bad resonance with HJPEV.
 * He has zombie time.
 * Quirrell as a horcux has some of the same problems as other proposed horcrux: namely, there are just too damn many of them, the author is skeptical of souls and the author's attitude toward superstition is kind of the point of the fic, and being a horcrux doesn't tell us anything about what he is doing with HJPEV or where he came from.
 * Quirrell's purpose is to return all of Voldemort's valuable, critical knowledge to him once he's ready. By obliviating himself, Voldemort more-or-less put his passions into HJPEV. By preparing it to teach himself, Voldemort more-or-less put his intellect into Quirrell. But the passions-vessel has gained intellect and the intellect-vessel has passions. So putting it back together, either by conventional instruction or some mystical-jam-sandwich-making is going result in something other than the original Voldemort.
 * Perhaps Quirrell is a construct created by magic, just like the Basilisk. When Voldemort learned everything Salazar knew from Salazar's Basilisk, he also learned how the Basilisk was made.
 * Or maybe Quirrell _is_ Salizar's Basilisk itself.
 * The Basilisk lasted a long time and it is reasonable to speculate that it did so by hibernating the centuries away. Quirrell needs to be more active than Salizar's Basilisk, but he still cannot last forever. So he hibernates at every possible moment. That's what zombie time is about.
 * Quirrell does state that he finds conversing in Parseltongue somewhat uncomfortable because he is not a true snake. So unless he was lying, which seems unnecessary, I would guess that he's not exactly a basilisk.
 * The resonance is a result of HJPEV/Voldemort's magic doing magic. There are issues with that kind of recursion.

Dumbledore is the antagonist.

 * He is the most powerful wizard in the world and has done some very nasty things, like:
 * waiting to face Gindelwald until the point where he would gain the maximum power from doing so
 * mercilessly burning Narcissa Malfoy alive
 * sending the infant Harry Potter to live with cruel (although they weren't really all that cruel, he just thought they'd be, which is kind of the same thing) step-parents
 * setting fire to a live chicken
 * sabotaging Snape and Lily's friendship
 * setting up Snape to play James Potter for a Uriah
 * abusing and killing his sister
 * attempting to force Hermione to subjugate or supplicate herself to HJPEV and his needs
 * and generally treating people as though they were pieces on a game board.
 * being willing to let
 * Dumbledore is deathist, so there's Author Appeal for him to be the antagonist.
 * This would also reflect the way things worked out in The Sword of Good, Mr. Yudlowski's other incomplete fantasy story.
 * Dumbledore is not an idiot, he is crazy. Insanity is the antithesis to rationality, not stupidity or 'evil' or even fate.

Dumbledore is NOT the antagonist.

 * He is an old and wise wizard who has been trying to do good, although not always successful. Possible explanations to the points above are:
 * He thought Grindelwald was a hero, a bit extreme, but still a hero. It was not until when, at some point, Grindelwald had somehow crossed the Moral Event Horizon that Dumbledore decided to intervene. It was a coincidence that Dumbledore had the most power to gain at that point.
 * Or he was telling the truth when he said that if he had acted any sooner, he wouldn't have been able to succeed.
 * Narcissa Malfoy is still alive under some sort of a Magical Witness Protection Program run by Dumbledore. The body Dumbledore burned was an animated death doll.
 * The death could have been faked using phoenix travel as it resembles being burned to nothing.
 * He wasn't really serious about the cruel step-parents thing. He just liked to mess with Harry's head.
 * Or he was, as Harry speculates, trying to put Harry in a situation where he couldn't depend on anyone else and had to develop a heroic level of responsibility.
 * The chicken wasn't really alive, but Transfigured from a rock. And even if it was alive, it is highly doubtful that the Wizarding World has some sort of a PETA organization. So what Dumbledore did wasn't really evil in the eyes of a meat-eating, Middle Ages society.
 * He probably saw that Snape was a potential Death Eater, so he tried to get an innocent Lily Evans away from all that darkness. His methods were questionable, but his intentions were good.
 * He thought the war could end quickly by bringing Voldemort directly to Harry Potter. Sacrificing close friends such as Lily and James Potter was a desperate and costly move on Dumbledore's part.
 * We don't know for sure that he abused and killed his sister. Dumbledore could be covering up for Aberforth for all we know.
 * He was using reverse psychology to get Hermione to become a heroine in her own right. He didn't expect her to rally up a whole squad of heroines, though...
 * To be fair, he's treating himself as a chess piece, not just everyone else. He probably thinks that Fate is the hand that moves the pieces.
 * Dumbledore may act crazy and inscrutable, but, in the end, he's really just a Boke looking for a Tsukkomi. Sadly, he's simply too intimidating for people to be brave enough to take up the Tsukkomi role...
 * I just thought he'd made a magical illusion of a burning chicken. He's the most powerful wizard alive, after all.

Dumbledore WAS evil, but went insane/good after fighting Voldemort.

 * It explains everything. All the evil acts Malfoy attributes to him happened in the past, before Voldemort's rise to power. Presumably, the realization that such a monster as Voldemort could exist AND Dumbledore himself would be unable to destroy him COMBINED with the fact that he either unwittingly helped or at least failed to prevent Tom Riddle from becoming Voldemort in the first place, yeah, that could cause someone to have a pretty big Heel Face Turn.

Harry is betrothed.

 * In Chapter 38 the Quibbler reveals details on the marital snarl that surrounds Harry James Potter-Evans-Verres
 * He is betrothed to Bella in that he is Voldemort and at some point Voldemort made a promise of some sort
 * He is betrothed to Luna in that he told Draco he would marry her.
 * He is betrothed to Hermione in that everyone at Hogwarts knows they're meant for each other.
 * He is betrothed to Draco because all of Sytherin House knows Draco is courting him.
 * He is betrothed to Kimiko Ross. He doesn't know it yet, but it's going to happen.

Magic in MoR-verse comes from Spiral Power.
Yudkowsky definitely knows about the show ("Breaking Drill Hex" has the incantation *Lagann!*), and something like Spiral Power would integrate well with Muggle science while still throwing everything Harry knows about the universe for a complete loop.

It would also explain how : being someone who makes friends and fights for them, she has access to more Spiral Power than Manipulative Bastard Draco or Chaotic Neutral Harry.
 * In continuation of this theory, Gurren Lagann could well be a documentation of the founding of the nation of Atlantis, with Kamina city as it's capital. "Magic" - with the need for the proper incantations and the imposed limits on what can be done with it - was created by Simon some time after the fall of the Anti Spirals so as to stop the Spiral Nemesis without cowing humanity's fighting spirit.
 * The Dementors are noted for having absolute despair as their primal effect, and you cast the True Patronus by thinking about the value of human life and the determination to defy all death and despair, forever. The Dementors are Anti-Spirals!

Harry will create a superintelligent friendly AI using magic or magical objects.
Since Eliezer Yudkowsky is writing this fic, it seems highly probable that artificial intelligence will pop up sooner or later. Plus, we already saw early on that magic can create conscious, friendly intelligences (the Sorting Hat). Harry's goal -- to discover the secret structure of magic so he can reorganize the universe -- may be beyond him as a child, but creating a magical superintelligence to do it for him may not be.
 * Magic itself may be generated by a super-intelligent AI. In chapter 25, Harry ponders:

Harry will create a superintelligent, seemingly friendly but actually horribly broken AI using magic or magical objects. It eats everyone.
Because Eliezer's thoughts on the subject mostly run to how consistently hard it is to make a safe AI, despite making an AI at all getting easier with every passing year. Harry wouldn't have a prayer, and Eliezer knows it. Harry does not.

The Pioneer Plaque isn't really the most secure place to put a Horcrux.
If wizards can Apparate anywhere, they can Apparate into outer space, too; they just need to wear a spacesuit or its magical equivalent, and to know where they're going. Apparition being limited to the speed of light (Quirrell regrets not being able to go to the stars) could be a nuisance, but it shouldn't stop them from getting there.
 * Can you tell me the exact location of the Pioneer Plaque relative to the device you're reading this WMG on, and the velocity at which its moving? Take as long as you like, but come back here with an exact location.
 * See http://www.wolframalpha.com/input/?i=pioneer+11+september+1991+distance+from+earth. At the time Harry is having the conversation, 3.13 billion miles (or 280 light minutes) away from earth. Moving away from the sun, at the time, at 12.7 km/s (http://www.wolframalpha.com/input/?i=pioneer+11+velocity+september+1991).
 * That's the distance, but you have no way of knowing what direction it's currently heading towards, or if it even maintained a straight line.
 * It hasn't.
 * It's at least imaginable that there could be a physical or magical limit on how FAR you can apparate. The Pioneer probe does not seem to be in "walking distance" any more. I doubt if in the books we ever saw anyone apparate more than 1,000 miles. So say a single "jump" can take you once round the earth... 10,000 or 12,000 miles. 3.13 billion miles would add up to a lot of apparitions and need at least a copious amount of stamina and determination to keep it up (and you'll have to keep in mind that you also would want to return sometime). That said you should be able to find out the "where" it is by means magical, as you already have "orientation spells" (Four-Point spell showing North with the help of your wand) and "call-back spells" ("Accio"), it's just not sure any wizard would still be able to reach it by now just depending on apparition. As to the "you can't apparate where you've never been" I'm rather tending to see this as a hazard-minimization rule... anybody not familiar with a place could end up in a floor or in solid rock, under water or in any other potentially lethal situation, so you only ever go where you have already been by other means. So if you were e.g. jumping to the Earth-Moon Lagrangian Point 1 where not much danger of hitting anything dangerous should be found you could go on and follow your magical detection methods up to the horcruxed plaque.
 * According to JKR's paracanonical Quidditch through the Ages, Apparition becomes increasingly unreliable over long distances, and most wizards do well not to attempt Apparating across the Atlantic. It seems reasonable to infer that astronomical distances are Right Out. Of course, you could do a series of shorter hops, but (1) it's a lot of hops, and (2) as it says below, it's now MoR!Canon that you have to have been there first.
 * According to Draco in Chapter 7, you can't Apparate to somewhere you've never been.
 * Harry has now been to it.
 * Harry has not been to it; the spell is an illusion on the environment, so Harry has only seen from its perspective. That may or may not be sufficient.
 * I don't think "outer space" is a specific enough destination. How sure are we that the view from space is specifically the view from Pioneer?
 * The sun would still be far brighter than any other star from the distance of Pioneer; Harry probably would have noticed that.
 * Not proof that Harry's been there, but at the distance of Pioneer, the sun would not be noticeable to Harry as anything other than another star, even if he knew exactly which direction to look.
 * Magnitude would be -19.1; I would call that noticeably bright. I do agree though that it's probably the view from Pioneer and the sun is maybe just underneath him or something and that's why he can't see it (I can imagine Quirrel doing this on purpose to avoid hard questions about "hey, what star is that?")
 * It is probable that the spell IS the view from pioneer because it is the spell to see whatever your horcrux sees.
 * I don't think anybody knows the position of Pioneer close enough to make a jump within a 10000 miles of it, note that all the numbers you gave give only a rough number.
 * In 7 years, I wouldn't be surprised if Harry's magic+science technology could catch up with Pioneer.
 * Harry knows about time travel now - another option is to remove whatever safeties are on the Time Turner, drastically alter what is considered 'possible' by the Department of Mysteries, and go back in time to get the Pioneer Plaque before it has left the planet.
 * Time travel in both canon and MoR appears to forbid changing the past. This is why Harry's prime number factoring algorithm fails; the universe doesn't iterate or converge to a stable time loop, instead there is a single self-consistent timeline.
 * It's still possible. Voldemort KNOWS that he horocruxed the plaque, but he only THINKS that the horocruxed plaque left with Pioneer. If Harry goes back to the point in time after the horocrux, but before the launch, he could destroy or replace the plaque without changing what we KNOW of the timeline.
 * This prospect appeals because Harry could take the opportunity to improve on the plaque, either by enchanting the probe to communicate all human knowledge, or by removing the directions to Earth if he thinks that's more prudent.
 * Would it be possible for Harry to just 'Accio' the Pioneer Plaque back to Earth?
 * In GOF, there was a long pause before Harry's broomstick came to him. The broomstick was stationary, and was on the same campus. Now, how long do you think it will take for Harry to both reverse the momentum of a plaque travelling at god-knows-how fast, that is in outer space.
 * In GOF Harry knew the spell for one day, was still rather weak in his magical powers and had not practiced all that much. It might be a thing which goes much faster if done by a well-trained/routined and powerful wizard
 * If I remember correctly, in canon Horcuxes couldn't be accio-ed, because there was a special spell on them. Given that Quirrelmort is at least twice as smart as canon!Voldemort, it's unlikely that he failed to do the same.
 * So? Just Accio the pioneer probe. The probe itself isn't horcruxed, the plaque attached to it is, so it should work. It all depends on how powerful Accio is. Knowing Harry, he'll eventually either try experimenting with Accio, or come up with an equally simple but completely different method of getting the plaque.
 * It doesn't matter how powerful Accio is, just have Harry politely ask the whole of the wizarding world to shout "Accio Pioneer Probe" at the same time. We know many Accios at the same time have a cumulative effect from when Harry was nearly killed by a fall when a load of people simultaneously tried to Summon him.
 * Voldemort is NOT stupid and would've realized that could happen and put the spell on the probe as well
 * The Pioneer anomaly is due to someone having tried this.
 * How about a portkey?

The Pioneer Plaque is no longer viable as a Horcrux for Voldemort.
As has been stated, at the start of Harry's first year the thing was already 280 light-minutes away. If magic in the Potter-verse is, as apparation limits seem to suggest, Slower Than Light, then the Horcruxes ability to tether a soul to the mortal world must also be Slower Than Light. Furthermore, there could be any number of space objects to block the signal somehow, even if the Horcruxes are somehow all on a Subspace Ansible style setup. Long story short? Whatever maximum range of effectiveness the Horcruxes have, the Plaque has long since left it.

Alternatively, the Pioneer horucrux still works correctly, but after all the other horucux have been destroyed, and Voldemort is killed, his disembodied spirit is drawn to his last remaining horucrux. He will spend the next several millenia wandering in interstellar space with the pioneer probe. Arguably, Voldemort might not consider this a bad fate.
 * He still might be able to return by apparition as he would only have to go one way; it even would be much easier than Harry's task to kill off the plaque. But there is a point of doubt: how does magic work and is the mean that does make it possible really given 3.13 billion miles out there? If e.g. it would depend on proximity to earth like let's say gravity, Voldemort could find himself quite squibby out there, a lot of risk if you ask me just for staying "alive".
 * Uuuh.... guys? Read the caption for the main Tropes page for MoR. Removing the Conservation of Energy gives us faster-than-light signalling according to Science... so why the hell couldn't we get some kind of faster-than-light magical transport by building on that?
 * I fail to see why the function of a horcrux would require some sort of "signal", faster-than-light or not. From what I understand of phylacteries and horcruxes, the devices work by creating an anchor for a person's soul to prevent it from moving on to the afterlife. When Voldemort was killed, a portion (perhaps even the majority) of his soul was still tied to the physical realm, so the last bit of his soul couldn't move on. No matter where the Pioneer horcrux is, or how far away from the rest of Voldemort's soul it is, it still anchors a portion of that soul to the physical universe. It prevents the complete death of the wizard by simply existing in the universe, not by casting some sort of spell as they die.
 * It wouldn't stop working. It would bring Voldemort back to life. It's just that then he needs some way for his soul to reach Earth. Which it won't.
 * Is it ever mentioned in canon that a soul is drawn to its Horcrux upon death? Voldemort only mentioned being blasted away from his body and settling in an Albanian forest, far away from any of his Horcruxes.
 * Your soul is NOT drawn to a Horcrux on death: Horcruxes are NOT used up. Let's look a a Dark Wizard with a Horcrux. He has split his soul in two and put one half in an object, making the Horcrux. If he is killed - hit with an Avada Kedavra for example - the soul fragment in his Horcrux is not affected. The soul fragment in his body cannot move on, i.e. cannot die, because part of it is safe. with the Dark Rituals used by Voldemort in Goblet of Fire, the soul fragment which was in the Dark Wizard's body can be reintegrated into a new body. In canon, it was Voldemort's in-body soul fragment which hung around Albania as Vapormort for a decade or so before finally resurrecting into a new body. It makes no difference whatsoever where your Horcrux is, so long as the soul fragment within is safe.

Canon!Harry would have been this smart if his aunt and uncle hadn't abused him.
Child abuse isn't good for your brain development, but canon!Harry doesn't show too many signs of it. This is because instead of starting out normal and ending up with big problems, he started out as a genius and ended up Brought Down to Normal.
 * Not only child abuse, but an ignorance of his rotating sleep cycles, sleep is one of the most important things when it comes to intellectual development and absorbing knowledge, and a lack of this fundamental resource would certainly stunt intellectual ability to perform.
 * Also lack of two professors for parents. canon!harry suffered in a state of close-minded neglect. MoR!Harry was taught and encouraged to learn from a very young age, that and an admiration for an auto-didactic way of life, make this theory highly possible.

Quirrellmort isn't trying to kill Harry because he already tried it, and it didn't work. That, and he figured out that he accidentally turned Harry into a Horcrux.

 * If Harry survived the Killing Curse the same way he did in canon, then Lily Potter's sacrifice would still be protecting him, just as it did at the end of the first novel. In other words, even though he thinks it's unlikely, Harry really does have a special "defeat Voldemort" power that he doesn't know about, and this Voldemort, being smart, isn't about to make the same mistake twice. Similarly, if Voldemort realized that Harry is now a Horcrux of his, he would want to keep that Horcrux intact.
 * Furthermore, Voldie subscribes to the "If you can't beat 'em, join 'em" school of thought and is actively recruiting Harry.
 * Voldemort learned from his experience at the dojo not to let his anger undermine his real goals. His real goal isn't dominance -- it's immortality. (A goal which he shares, by the way, with the fic's author!) Like the author, Voldemort actively seeks to become a more rational person. His earlier attempts to do this through dominance *failed*, and he has *learned* from them ... as he did with the dojo incident.
 * What's this about Voldie undermining his goals at the dojo? As far as I can tell, he succeeded. He not only learned the martial arts he wanted to learn at the best dojo in the world, he then killed everyone else there so that he'd be the last man on earth that knew martial arts as well as he does.
 * He didn't learn any martial arts. That was the entire point of the story. Quirrell says both of those things in unmistakable black-and-white terms.
 * However, Quirrell is not a reliable narrator. In his story, he claims that he learned martial arts from the dojo, but Voldemort failed to because he killed everyone in the dojo. But if (as we're all assuming) Quirrell is Voldemort, then both parts of the story cannot be true: either Voldemort killed the Master and students (and subsequently learned from his error), or he did not kill them because he realized that his prior methods (the "Voldemort" methods, as opposed to the "Quirrell" methods) were flawed. Since Quirrell does know martial arts, the latter would seem to be most likely. In this scenario, the "Voldemort" part of the story never actually happened, because Quirrellmort realized that it would be futile.
 * Both parts of the story can be true. Voldemort, using some sort of a false identity, goes to the dojo. He attacks his sparing partner, hears what the master has to say, and does just what he tells people Harry will do. He pretends to lose, learns martial arts, and then comes back later to kill everyone except one student, who was a friend of his. This accomplishes a number of things: it lets him learn martial arts, it keeps anyone else from learning from the same school, it lets him kill everyone who he "lost" to, and it helps to give the false impression that he cannot control his temper.
 * Both parts of the story can be true another way. Quirrel learned martial arts at the dojo, and Voldemort also acted as described. This happened before Quirrelmort appeared. Quirrelmort now knows martial arts because of the Quirrel part, not the Voldemort part.
 * We have no proof that Harry is even a Horcrux in MoR. There are other changes to canon though out the story as well -- significant ones -- and the Sorting Hat specifically said that there are no other minds in Harry's head, or the Sorting Hat would be able to talk to them. If you put the sorting Hat on Tom Riddle's Diary, the Hat probably would be able to talk to him, since a Horcrux is a portion of a person. (If Diary Tom Riddle can talk to people, it should be able to talk to the Hat.) "I can go ahead and tell you that there is definitely nothing like a ghost - mind, intelligence, memory, personality, or feelings - in your scar. Otherwise it would be participating in this conversation, being under my brim." (chapter 10) Of course, the Sorting Hat could be wrong about that. However, I don't think it would deliberately mislead Harry about the presence of a Horcrux on his person based on it's other actions during the sorting.
 * On the other hand, Canon!Harry had no guest during his canon!sorting, and he absolutely was a horcrux. The same absence exists in both canon and MoR, so the same horcrux could be there.
 * Except that in canon A) The hat didn't check for those things, and B) the hat in MoR is completely different than the Hat in Canon. That's rather like saying MoR is proof that Quirrell was acting in The Sorcerers Stone.
 * During the prison breakout in chapter 56, Harry's "mysterious dark side" seemed suspiciously independent of the rest of his mind. To me, it's at least a strong hint that he's a Horcrux, though what that actually means in the MoR universe is still up for grabs.
 * The mysterious dark side Not to mention the apparent similarity of their personalities.

The rock that Dumbledore gave Harry is actually the Philosopher's Stone.
The heavily guarded hallway is just a decoy. This Dumbledore is hiding it where nobody would think to look.
 * CREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEED!
 * The "Rock" is actually a shell/protection the philosopher's stone is actually hidden inside it as a camouflage

The rock is a perfectly ordinary rock
Dumbledore wanted Harry's efforts diverted from wreaking chaos. He may have anticipated Harry's transfiguration plans, and believed that this would be an excellent exercise to improve Harry's magical prowess.

"One killing curse will bring it down!"
A critical scene in the first book is that of the trio taking down the troll in the girl's restroom. As Draco has largely supplanted Ron's role in this fic, his method for surviving such an encounter may provide an interesting twist in the future narrative. What's an Avada Kedavra amongst friends, after all? "There is a time and a place for taking your enemy alive, and inside a Hogwarts classroom is usually one of those places." If Draco leaves her be, there's no reason for Hermione to get cornered in a bathroom this time, after all...
 * Inevitably, the Killing Curse will be cast through REASON and RATIONALISM. It's not like unusual castings of it have no precedents...
 * Extending this: Harry will be able to cast it through reason and rationalism, but only when taken over by his dark side. We've already seen that it has the necessary priors to develop a logical proof that "anyone who annoys me needs to die", which is not something Normal!Harry is likely to decide.

Mr. Hat and Cloak is...

 * The Author
 * David Xanatos himself. It's been established that there are tales similar to Gargoyles in this reality for wizarding kind so assuming they're true it wouldn't be too outlandish to have Xanatos or one of his descendants really having a hand in Hogwarts.
 * Severus Snape. He is the Head of Slytherin House, after all!
 * He's also bad at understanding young girls, capable of casting the memory charm, and one of the few people who might refer to Dumbledore as "Albus".Additionally, he's one of the few people Hermione would panic upon seeing.


 * Harry Potter himself under the influence of Roger Bacon/Tom Riddle's diary. After eight chapters it has to have taker some effect.
 * Harry hasn't used the journal as of chapter 37:
 * Prof. Quirrell. Note that after Quirrell's conversation with Blaise and then Harry, he heads off in the same direction Blaise went. Prof. Quirrell also has excellent motivation for wanting to make Dumbledore look bad. Mr. Hat and Cloak would also have a very easy time predicting Prof. Quirrell's reactions if he is Prof. Quirrell.
 * Mr. Hat and Cloak: "... entity which Salazar Slytherin keyed into his wards at a higher level than the Headmaster himself." Prof. Quirrell: "... Salazar Slytherin would have keyed his monster into the ancient wards at a higher level than the Headmaster himself."
 * Note also that just before heading off, Quirrell says he needs to do something of some urgency - i.e., he needs to catch Blaise before he reaches Dumbledore.
 * And he has an excellent motive: provide Harry a strong evidence of him not being Voldemort. He offered Harry to defeat fake Voldemort and now he's trying to to convince Harry that he's actually the impostor acting for Harry's sake. And he's very disappointed about Harry's actions to save Hermione because that means Harry would never forgive him for striking her even if trusting that Quirrell isn't actual Voldemort but fake one.
 * Lockhart. Blaise Zabini is a quintiple agent, but Mr. Hat and Cloak does something to make him think that he's only a quadruple agent. Sounds to me like a memory charm, and whose specialty is that? Possibly it's a Lockhart influenced or possessed by Voldemort, since he seems to have knowledge of Slytherin's monster.
 * Of course, Hermione recognized him. So . . . perhaps she recognized him from a book cover . . . or not.
 * Sybill Trelawney
 * Harry, from the future. He's now trying to fix everything in the past.
 * Now with support! Mr. Hat and Cloak's voice catches on the word time when he's asked how he knows all the answers and riddles and questions. HE'S A TIME TRAVELER! Maybe not Harry, but definitely a time traveler.
 * The Gray Lady (aka Helena Ravenclaw). The form that Mr. Hat and Cloak revealed to Hermione at the end of chapter 76 resembles her, and instead of just assuming a form that Hermione would find appealing, she assumed her own, true form. The ghost of the daughter of the founder of Ravenclaw house is the one behind everything.
 * Mc Gonnagal- everyone else is plotting, so why not?

The Incident with the Science Fair Project involved showing up with a nuclear bomb.
Not only would this be an appropriate pop-culture reference to allude to for a Child Prodigy, it would also actually be about twice as severe as what he inflicted upon poor Deputy Headmistress McGonagall. And Harry's crazy enough to do it.
 * Or just a nuclear reactor. There actually was a teenager who literally built a nuclear reactor in his backyard by getting lots of old radioactive paint and putting it all in one place.
 * One of the more famous episodes in the history of the University of Chicago scavenger hunt was when two students built a nuclear reactor and earned both a lifetime scav ban and eternal fame. Moral: if it's on the scav list someone will show up with it.
 * I think the story about the Teenager had him getting his radioactive material from smoke detectors. He was able to buy large numbers wholesale and extract the very small amount of material in each.
 * That would be this guy, for those who may think that is too weird to be true. Nope.
 * Point of order: Making a nuclear reactor is easy: You find a bunch of a special kind of rock, pile it up, and run water through it. When the water comes out, it's hot. You can build a nuclear reactor with stone age technology, if you don't mind contaminating the site, and with bare hands, if you don't care how long your workers live. David Hahn made his reactor out of americium disks and aluminum foil. But a nuclear weapon requires precise machining of radioactive metals under inert gas and very accurately timed explosives. If you don't already have the material, it becomes orders of magnitude more difficult.
 * Actually, not so. A lens-type weapon (can be used with either plutonium or uranium, higher yield) requires precision-machined slugs and timed explosive, but a gun-type (lower yield, uranium only) can be made easily with standard machine tools, assuming you have no regard for your own life.
 * To summarize, it's plausible that Harry built a reactor, and freaked out the authorities; but it is not at all plausible that he built a nuclear weapon with then becoming imprisoned.

The diary Quirrellmort gives Harry isn't really Roger Bacon's.
It's Tom Riddle's. (or both)

Fred and George used Polyjuice
Rita Skeeter was never fooled at all. Fred and George pretended to be Rita Skeeter and published the article in her name using poly-juice potion and a few other things, taking advantage of the fact that Rita Skeeter had gone undercover to follow Quirrel after his plot to get her into Mary's room.

It's obvious when you look at it. They never 'warmed' the top of the plate. They just flipped the plate over! They never fooled Rita, they fooled the other people in the newspaper company!

Quirrel did it
His confusion was an act, Fred and George's conclusion that they agreed to be Obliviated was incorrect, he had more reason to believe Skeeter was in the room than simply knowing her secret and deducing that was a place she was likely to hang out.

Rita's was shown doctored memories
As Quirrel explains, changing the actual records that Rita cited in her report, and then changing them back, should have been impossible. Therefore, the records weren't changed. Rita came to be convinced of their contents without ever having seen them. One way that I can think of to do this would be for the Weasley twins to mess with their own memories, Obliviated themselves (so they forgot that the fake memories were fake), used a Pensive to extract the fake ones, gave them to Rita, and then Obliviated themselves again (so they forgot the fake memories completely). Or something like that. Rita, because she didn't really care about accuracy, never bothered to check that the actual records matched the memories.

Dumbledore did it
Dumbledore is mentioned in the fic as being extremely skilled at transfiguration. He has legitimate access to the Wizengamot proceedings, and so could have transfigured the relevant transcript to alter its text. It would have reverted on its own some hours or days later. Likewise, the wedding contract could have been transfigured from something tiny, or from thin air, and reverted within the vault after it had served its purpose (just because Harry couldn't transfigure air on his first try doesn't mean it's impossible). Dumbledore has excellent motivation for this; he's presently playing the game against Lucius Malfoy, and Rita Skeeter is Lucius's pawn. This would also explain Dumbledore's later "accidental" gift to the Weasley twins (it's pretty clear from their explorations of the forbidden corridor that he's been grooming them as useful pawns).

Rita Skeeter did it
The twins told Rita that they had the scoop of a lifetime, and gave her some of the highlights of the insane theory they were peddling, then told her they had evidence to back it up but it was all highly sensitive and they'd have to obliviate her after she saw it, so she wouldn't know who they were or how they'd found the information. After being allowed to write down that plan, she agreed. The twins first asked her write down all the details before providing evidence, so she would know what the evidence was supposed to spport. After this, when they were supposed to give her evidence, they obliviated her. Rita awoke thinking she must've had one hell of a reason to write all that down so, rather than second guessing herself, she assumed she must've been shown the evidence as promised.

This timeline is a result of one or more peggy sue
In chapter 29  with this information we can assume that the influence of one or more peggy sue is possible, one that is very likely might be
 * Harry seems like a likely culprit, given the amount of magiscientific knowledge he will probably later gain. He could either create the Canon!Timeline so he can become Book Dumb but happy, but the more likely scenario, given the personalities of Harry and the author, is that, paradoxically, he creates the Logic!Timeline. Quirrel is almost certainly one of the people who remembers everything, as evidenced by his gauging Harry's reaction at mentioning the use of an unknown dark spell by a sixth-year and a few other things that haven't happened but did in the books.
 * Perhaps Canon!Harry created a timeline where he had a better childhood?

Quirrel isn't Voldemort host
Why he doesn't cause headaches or any pain when near Harry? The answer: someone else is the host. Quirell, however, still has a deep connection with Voldemort.
 * Omake File #1 from chapter 12 addresses this. If Harry felt headaches when looking at Quirrell, he'd have figured it out and told Dumbledore within a week, and the fic would be over already.
 * The Question becomes then, where the hell is Voldemort, or better yet WHO if Voldemort
 * He does, remember? In Chapter 17, he goes to McGonagall about his sudden sense of doom surrounding Quirrell, and McGonagall tell him that if he speaks of it again "any earlier than the Ides of May, I will string you up by the gates of Hogwarts with your own intestines and pour fire beetles into your nose." There's also the part in Chapter 3 when he sees Quirrell in the Leaky Cauldron and has an Ominous Feeling.
 * Or... Quirrel's still not Voldemort, but another human horcrux?

Bill Weasley isn't a Peggy Sue
His delusions are actually caused by Peter Pettigrew, possible because Bill find out his secret or something similar, so Peter altered his mind to make him look crazy and faked his own death afterwards, not many people would take time to exam a rat's corpse when a family member went crazy.
 * Word of God dismisses this. In the Author's Note to (IIRC, have since been deleted) Chapter 32-33, Eliezer states (quoting from memory) "for Peter Pettigrew to go into hiding, of all places, as a pet rat in an enemy wizard family would require him to be holding the Idiot Ball".
 * Alternately, Bill discovered Peter was alive somewhere else, and Peter managed to alter his mind to have Bill think he'd discovered him as Scabbers, which has the result of Bill thinking he'd killed Peter, everyone else thinking Bill is nuts, and Peter undiscovered.
 * My guess is that, in this universe, when Sirius Black went after Peter Pettigrew, he succeeded in killing him before getting taken away to Azkaban. Pettigrew died in that magic explosion, and Scabbers was just an ordinary rat all along.

Bill is a Peggy Sue from a universe similar to canon
In the universe that Bill is from, the rat really was Pettigrew, so Bill isn't insane, but in this universe the rat is just a rat (and a bunch of other things are also different), so Bill looks completely insane to everyone else.

Someone will turn out to use the Imperius Curse oddly for fun and profit
More specifically, at least one savvy individual will turn out to habitually use the Imperius Curse on themselves and/or consenting others as a substitute for normal willpower (to help overcome/override fears, addictions, apathy etc.). Just because the fact that nobody in the books even considered peaceful and self-directed/consensual uses of mind control always bugged me. Plus it'll cleverly highlight the discrepancy between what intelligent, sane people know to be rational and what they actually do.
 * See one of the WMG entries below which guesses that Lily Imperius'd Petunia into having a better body image and more healthy habits.

Harry Potter is Shinji Ikari
Lets go over the signs:
 * Harry Potter and Shinji Ikari are around the same age.
 * Harry Potter and Shinji Ikari are both exceedingly intelligent child prodigies, with a knack for Gambit Roulettes. And megalomania.
 * They both try to avoid becoming megalomaniacs.
 * Shinji Ikari has four internal advisers, representing orks, eldars, chaos and the empire.
 * Harry Potter has four internal voices, representing Hufflepuff, Slytherin, Ravenclaw and Gryffindor
 * Harry Potter is popular with the girls
 * Shinji Ikari has a harem
 * Shinji Ikari has been responsible for critical industrial and scientific advancement in his vicinity.
 * Harry Potter is trying to create critical industrial and scientific advancement in his vicinity.
 * Harry Potter and Shinji Ikari are both trying to save the world by going Serial Escalation by utilizing reason as a cold steel bludgeon.
 * Harry Potter has created a Legion of Chaos. It consists of young kids.
 * Shinji Ikari has created an entire ork waaagh. It consists of young kids. Also? Space Marine army.

Quirrelmort is only as smart as he is because Harry's horcrux redirects some of Harry's I.Q. to Voldemort.
And this competency explains every other discrepancy in the fanfic. Except Dumbledore's silliness. That was always there.
 * It doesn't solve the discrepancies of events before Harry was born. It does however lead to a legitimate reason for Voldemort to be stronger in areas than Harry.

Harry's father's rock is actually Harry's father.
James, either mortally wounded or otherwise doomed, transfigured himself into a rock.
 * McGonagall claims this would be possible, but the transfiguration would have to be maintained and the subject would probably die after being untransfigured. Not necessarily a good idea, but not outside the abilities of James Animagus-by-Sixteen Potter.
 * Dumbledore, desperately searching for "The power the dark lord knows not," can tell that James performed powerful magic on the rock and assumes that it is important. Otherwise, he knows that James is the rock, and knows that James will untransfigure at some crucial moment to save his son's life. The second would explain why no-one misses James' corpse.
 * Alternatively, James can't untransform because rocks aren't conscious, and will only be put right (and then die, after a couple of days) when Harry tries to transfigure the rock into a gem.
 * This theory echoes quite well with the author's view on cryonics.
 * This would explain why being in the bag and thus in Harry's reach is not good enough--the point isn't that the rock will protect Harry, it's that Dumbledore was told what the rock is and between him and James they decided that on the off chance that James was conscious he should try to arrange it so that James could "watch over" Harry by being present with him as much as possible.
 * Alternatively, James has a different Animagus transformation is this world: A rock. Or he has several Animagus transformations.
 * A pet rock! Harry's pet rock, the one that died! The rock at this time in the story is the pet rock future-Harry resurrects with the power of science-magic and sends back in time with a souped-up Time-Turner to help himself!

Luna can see beyond the fourth wall
Think about it. She tells her father what she sees, events that are happening in a relative 'future', in other Harry Potter fanfics. Being a girl on the cusp of puberty, her sight naturally gravitates towards yaoi in her early attempts to control the ability. Her father takes her visions to be that of a Seer, and publishes them front page every time she shares one.
 * The author commented that if Luna turns out to be a seer, she won't be crazy, but her father will interpret her visions in his... odd manner. The whole "Draco malfoy is pregnant" would come from something like "Light will plant a seed in the heart of the darkness"
 * That's pretty close to being confirmed. If he wanted to Joss it, he could have simply said "Luna isn't a seer".
 * I think it means Sure Why Not.

Harry kills Voldemort, but allows him to 'inhabit' his Horcrux.
This has been so heavily foreshadowed, in my opinion, that it may not count as wild. The prophecy in this verse is altered specifically to allow a "remnant" to remain outside of this world...in the absence of an afterlife, what else could that mean? And numerous comments from PresumablyVoldemort!Quirrell suggest that he'd consider this a happy ending--sleeping for millenia surrounded by the beauty of space, away from the world he'd dearly wish to leave.

Quirrell's master plan is to set up a recursive Horcruxing
To elaborate: Quirrell is aware that Harry is a Horcrux. He wants to somehow get Harry to use HIM as a horcrux. Then it will be logically impossible for either of them to die. So he gets eternity to enjoy torturing and/or ruling the world with the boy who lived.
 * Except if a third party stabs them with a basilisk fang or the sword of Gryphindor or something...

Harry is going to discover a way to mass-produce Philosopher's Stones
Being the only source of non-evil life extension in canon, the Philosopher's Stone is exactly the kind of thing that MoR!Harry would be desperate to get his hands on and then give to everyone else.

Harry isn't going to be able to get the stone like in the first book
The spell that Dumbledore used, had the restriction that it should be someone that didn't want to use the Philosopher's Stone. Harry would every much like the idea of using one.

Harry's father's rock is just a rock
I can easily see James setting up a situation that would make his son carry around an ordinary rock for the rest of his life.
 * Alternately, one of the trials will be solvable with an enormous rock.

The pattern of the horcruxes
We know where one horcrux is: in space. We know Quirrell found Harry's ideas of where to imprison a Dementor to be suspiciously interesting: in the earth's core; in solid rock; sunk in the Marianas Trench; floating in the stratosphere; and shot into space.

Now, in canon, four of the horcruxes are in artifacts belonging to the Founders, whose Houses correspond to the classic alchemical elements: Gryffindor is fire, Ravenclaw air, Slytherin water, and Hufflepuff earth.

Quirrell, as a wizard, saw the same alchemical pattern in Harry's suggestions: fire (earth's molten core), earth (solid rock), water (Marianas Trench), air (stratosphere), and aether (space). Harry, on the other hand, still hasn't read his Roger Bacon!
 * The entire Dementor plot may have been an attempt by Quirrellmort to put Harry into stronger contact with his dark side/the evil soul fragment. In canon, Voldemort hid his Horcruxes and then sought to recover them; if MoR!Quirrellmort obliviated himself after hiding them, he may have realized that Harry is a Horcrux and contains a fragment of his soul from before he obliviated himself, and Harry might therefore remember where the Horcruxes were hidden subconsciously. Quirrell is pleased with his plot because Harry confirms his suspected Horcrux locations, thus his comments that it was a good day.
 * Incidentally, I bet the reason why the Dementor said he recognized Quirrell and would hunt him is because he recognized Voldemort as someone who has cheated Death.

Why Harry and Hermione can't cast an animal Patronus, but can't tell anyone why
Dementors represent Death and its power to inspire fear, hopelessness, and despair. Animal Patronuses represent irrational faith in life after death; they are symbols of the wizard or witch's self-image of their immortal soul. (For comparison, see the Egyptian depictions of the soul as a bird.)


 * Or The animal Patronus is the result of ignorance (Willful in the case of Draco, but perhaps others can do so merely by being happy-go-lucky); note how Harry teaches Draco to cast the Patronus (the hints about imagining that the dementor is the fear he experienced when he thought he might die; and to imagine the life-affirming quality of his father coming to to the rescue as the basis for the Patronus). If ignorance is the basis, then it easily explains the limitations of the animal Patronus (people still being affected by dementors while a Patronus is up) and why if the basis for the True Patronus were taught that people would be left defenseless; not everyone is ready and able to overcome ignorance. Godric Griffyndor possessed the necessary courage to take the next step, but he lacked the core idea (he did not recognize the dementor as being death).
 * Actually, Harry decides Godric likely did know Dementors were death. Unlike Harry however, Godric would never have thought of DEATH as something that could be defeated. He probably didn't tell anyone for the same reasons as Harry: doing so would take away the ability to cast Patronuses.

Rationalists don't have irrational faith, or at least don't want to have any; and they don't believe in immortal souls. Neither did grizzled war-veteran Godric Gryffindor, who'd seen too much blood: he'd seen his friends die, and killed his enemies, knowing that was the end for them. Hence, neither rationalists nor Gryffindor could cast a Patronus.

Harry's human Patronus represents his faith in humanity (hence the chapter title, "Humanism"), and specifically his faith in humanity's ability to conquer Death through reason. However, in order to explain this to someone who uses an animal Patronus, he would have to convince them that their faith in life after death is wrong -- thus, taking away their ability to cast the animal Patronus.


 * This troper feels that this idea was explained in the story and shouldn't be considered a guess.


 * This troper feels that, while this explanation seems prima facie correct, the portion of the theory based on life after death is incorrect. Most people who cast patronuses are not focusing on feelings that correspond to life after death let alone memories or ideas that indicate life after death. Yes, it is clearly indicated in Harry's "explanation to Draco" that conquering death is a key to the Patronus 2.0, but that is because Harry has a key component that almost everyone else lacks. He knows that Dementors are Death. And I would posit that it is far more likely that it is the ignorance of this fact that allows the animal patronus to work (while being flawed). Just how many people would, when faced with a stand in for the Grim Reaper, have the courage to tell Death to buzz off?


 * I though it could have been more like comfort vs. confidence. The comfort makes you feel better, but the confidence blocks you from feeling bad in the first place (the dementor-harming property of the light is the same as the original, just a lot stronger and more purified without the interference getting through). As to why Harry and Hermione aren't allowed to tell others about the Patronus 2.0, I always thought it was more about the dangers of incomplete knowledge escaping. Until the Hogwarts admins, Harry, and Hermione know more about Patronuses and the Patronus 2.0 (and possibly even then), the information will be suppressed to keep it out of the hands of those competent enough to use it incompetently (and probably those who are thought to be the opposition by Dumbledore).


 * The animal patronus could be from simply using a memory that states that you are currently alive. The Dementor then cannot kill you until it overcomes the patronus memory. This is why the Dementor can still be felt from beyond the patronus: While you know you are alive, you don't know about anyone else. Harry and Hermione are unable to produce an animal patronus because they do not have any memory that shows they are alive: Their rationalism does not even allow them to admit their existence. However they can likewise imagine that death is an illusion which allows it to be defeated. In order for Dumbledore to cast Patronus 2.0 he would have to give up on more than hope for life after death: he would have to admit he possibly never existed at all. This could prove fatal considering life extension techniques may depend on one believing they are alive.

Lily didn't use a potion to help Petunia.
When Lily said that there wasn't a potion that could help Petunia lose weight and become more beautiful, she was pretty much on the mark. When Petunia got to the point of saying risking death was worth it... Lily brewed up a potion that was generally placebo... and applied a self-improvement Imperius.


 * Harry believes he sees the signs of a powerful magic potion on her when his parents pick him up from the train station. Of course, she's told him she thinks a potion has been used on her, biasing his observations...


 * Lilly DID use a potion to help putunia. That potion is, in fact, the potion of "eagle's splendour" Dumbledore referred to in her fifth year potion book. Dumbledore added a note there "I wonder what would happen if you used Thestral blood here instead of blueberries?", which is what encouraged/allowed Lilly to make Petunia better looking. As such, Dumbledore assured that Harry's step parents wouldn't be wicked, and as Petunia ended up marrying a much smarter person because of this, Harry ended up as rational as he is as a result. It's all part of Dumbledore's master plan.

Vold!Quirrell is Harry
Vold!Quirrell is actually an old Harry, who has removed the limitations on the Time Turner. He attempts to kill himself as a kid (perhaps some kind of crisis of consciousness, knowing he's failed at becoming a god/attempting to unify the Muggle and Magic worlds) to break the Stable Time Loop but fails because, well, it's stable. He's now showed up to Hogwarts at the same time as his kid self in an attempt to mentor himself and, in a kinder-gentler-subtler fashion, break the Stable Time Loop, or perhaps he realizes he must fulfill it.

Explains why he's always so dang curious about what Harry thinks about things, especially off the top of his head; relates to Harry's horror at watching himself pull Neville out of the ring of bullies.

Or, yeah, I'm seeing how time travel is so stupidly powerful that it lets you explain anything however you like. It's limited by Stable Time Loops, but barring attempting to do things the Author hasn't made up his mind on yet (P = NP) you get to do anything you want to the world. - AF802CAA

Voldemort voluntarily retired from Dark Lord status, with Dumbledore's knowing assistance
Per early chapters, Quirrelmort realized early on that he didn't want to be a dark lord (the requirements for being a successful, rational one made it pointless). The description of Voldemort's final attack in "Humanism" very carefully avoids confirming that he tried using the Killing Curse on Harry, and in fact suggests that a different spell was used (the "strange word" unknown to Harry that Harry hears in the memory). Forming a horcrux requires sacrificing a living person. Voldemort's original form was almost completely annihilated during his attack. This could have been due to him using himself as the life-force to create a horcrux in Harry (or possibly elsewhere), and incidentally fulfilling a prophecy at the same time (destroying all but a remnant of himself). More mundane forms of destruction (not forming a horcrux) would also work, given that he had horcruxes already in place to prevent true death.

Per "Humanism" part 4, Harry knows that Dumbledore thought that setting up the attack on Harry's family will immediately end the war. The most direct way for that to be the case would be for Dumbledore to have formed an agreement with Voldemort for exactly that to occur, per Voldemort's desire to retire. Retiring with the knowing assistance of Dumbledore is consistent with Dumbledore offering Quirrelmort sanctuary when threatened by Dementors in "humanism". It is also consistent with Dumbledore carefully not investigating the Aura of Doom around Quirrelmort. It at first appears inconsistent with Dumbledore's strong opposition to Dark Lord Voldemort's dark-lording, but it becomes consistent if providing sanctuary and setting up Voldemort's apparent death is seen as part of the "sacrificing everything" that Dumbledore mentions doing when describing the war to Harry. Dumbledore wanted to stop Voldemort's terror campaign at any cost - even if the cost was helping him retire.

How Quirrel ended up as the host for Voldemort's consciousness is left as an exercise, but as this happened in canon too, it's assumed to be a solvable puzzle. How Voldemort convinced Dumbledore that he'd uphold his end of the deal is also left as an exercise.


 * A simple exercise, methinks: Unbreakable Oath?
 * "All oaths are unbreakable, when made by the right sort of person." Maybe Voldemort is more trustworthy than in canon?

Quirrellmort is hedging his bets, both recruiting and trying to eliminate Harry.

 * When Draco dropped Harry, Quirrellmort tried to kill Harry and frame Lupin. We know it was Quirrell who asked Lupin to come. As a werewolf with previous ties to Sirius Black, Lupin is vulnerable to such accusations. Quirrell cast a super-gravity spell that pulled down everyone in the area - Harry, himself, the 200 girls - everyone except Lupin. When Harry survived, Quirrell stayed on the ground until he could decide on the best course of action.
 * Quirrell knew how the dementor was reaching Harry because Quirrell engineered the situation. The reason Quirrell saved Harry from the dementor was that Hermione was about to go in front of it, at which point the dementor would have revealed Quirrell's plan.
 * That Quirrell is working to win Harry's trust is not exactly a wild guess. Quirrell has just received some data that indicates his plan is working: Harry protects Quirrell from threats, such as the dementor. Harry has even picked up Quirrell's characteristic gesture: in Humanism Pt. 4, we see him tap his cheek thoughtfully.

Quirellmort knows about the resurrection stone.

 * Harry told Quirrell the markings on the stone (pretending to be wise, pt 2), which mark the Peverell/Gaunt ring horcrux in the canon.
 * "The key to a puzzle is often something you read twenty years ago in an old scroll, or a peculiar ring you saw on the finger of a man you met only once." -- Quirrell Ch26, Noticing Confusion.

Dumbledore broke up Lily and Severus.
Lilly used to date Severus, but Dumbledore deliberately broke them up by writing helpful notes in her potions textbook. ""Lily thought her boyfriend was the one writing them and they had the most amazing fights.""


 * In a recent Author's notes: 'Ch. 17 has now been retconned so that Dumbledore now speaks of Lily's "friend" instead of "boyfriend", since the original was an error on my part rather than an intended departure from canon.' Thus, it appears that the author previously believed that Lily and Severus were dating, but then discovered that they were only friends, so he changed things to make them more canon-compliant. However, this DOES back up the theory.
 * This is the "Terrible Secret" that Dumbledore shares with Harry as a show of confidence (even if Harry doesn't understand it at the time). Even if Lily and Severus were just friends, sowing discord between them was a horribly nasty thing for him to do. Dumbledore probably had his reasons, but they would have to be REALLY good reasons to even begin to justify his actions.
 * He did have a really good reason. That one act allowed him to defeat Voldemort and save the world. By breaking Snape up with Lilly, Snape finally went off and joined the death eaters. This caused him to bring the prophesy to Voldemort, which caused Voldemort to target Potter, which caused him to be destroyed. And Dumbledore got Snape back on his side anyway, as Voldemort ended up killing Lilly, just as Dumbledore knew he would. At the same time, he ensured that Lilly ended up helping petunia with the "potion of eagle's splendour", thus ensuring that Harry would have a much better upbringing, so that Harry (who is actually Voldemort) ends up as a good guy. He really is a magnificent bastard.

Harry can't hear dementors

 * Although, since he can’t see them either (the fic claims directly that his brain “refuses to be mislead by their illusion”), this might be just “natural”.

the "important task" McGonagall got called away from

 * Conservation of detail would suggest that’s a hint, but since it doesn’t seem related to anything else it might be just a future reference.
 * Guarding the Philosopher's Stone, I'd bet. Along with Snape, who (Quirrell mentions later) cancelled all his classes for the day. Dumbledore thought that was the real plot the Dementor was supposed to distract security from.
 * (Same as previous troper, you know how it is when you write something and think of new implications five minutes later) ...Dumbledore (ch. 40) "And I do believe I know what it might be a distraction from, if Professor Quirrell means ill... thank you, Harry." How much more does Dumbledore know about Quirrell than he's let on?

How come the Dementor knows and singles out Quirell for hunting him?

 * The obvious thing would be “punishment” for trying to escape death, but it really sounds as if they had met before. If the Dementor is just borrowing memories and processing ability from the viewers’ brains, it might mean that it’s not necessarily this same Dementor, but Quirrell would have met one and annoyed it. So how exactly did Quirellmort meet a Dementor, and annoyed it, and survived, without apparently being able to cast a Patronus (and with most Slytherins in the same situation)? Is his line about the attempts to destroy Dementors a personal history hint or just informative?
 * If Quirrell encountered a Dementor in the past, he probably just did what he told his students to do in his "One Killing Curse will bring it down!" rant at the start of his first lesson (ch. 16). "You just Apparate away!"

What happened to Fawkes?

 * The bird launched itself at a Dementor and poofed. No one remarks on it. What happened to Fawkes? Additionally, Dumbledore is shocked that Harry can hear Fawkes. (If phoenixes are immortal, perhaps they are created by tearing something out of the world? The phoenix is undying and the Dementor is the wound they leave behind? Note that if this is the case, you may have to chuck a phoenix at any Dementor before Harry could do his thing.)
 * It was made pretty clear in the story the Fawkes told Harry to take another stab at casting a Patronus for the sake of not letting the Dementor get away with that crap. Since Phoenices cannot talk, Fawkes stooped at the Dementor to indicate "attacking." Then...it poofed back to Dumbledore's office. We know nothing bad happened since Fawkes is seen again later in Azkaban. Thus, YOU CAN BE QUITE SURE that it is the One True Patronus that killed the Dementor and could do so again at any time.

The story behind Narcissa Malfoy's death is...

 * Dumbledore caused it by accident, and then confessed it to Lucius.
 * Narcissa became a horcrux for Voldemort, and Dumbledore had to destroy it.
 * Voldemort did it, and shifted himself to look like Dumbledore when speaking with Lucius. This would gain Lucius loyalty against Dumbledore.
 * She's not dead. Dumbledore helped her fake her death so she could escape once she realized who Lucius really was.
 * Being burned alive sounds like a possible accident while using the Fyendfire spell. IIRC Goyle died this way in canon; it’s possible but not necessary that Narcissa cast the spell. Quirell’s mention that it doesn’t work on Dementors might be a hint at this, too.
 * Dumbledore killed her as retaliation for Death Eaters attacking the families of the Order of the Phoenix. In Chapter 62, Dumbledore says "The Death Eaters learned, toward the end of the war, not to attack the Order's families." It's hard to imagine what else he could have done to make them "learn".

Quirrelmort is intelligent not because of some complex Peggy Sue or leeching of IQ...
But because like pretty much everyone else he was upgraded significantly. This isn't a For Want of a Nail fic, this is a fullblown AU. Harry is not the only character changed from Canon, and it clearly does not all originate from harry himself. If Voldemort was as incompetent as Rowling wrote him, then Improved!Dumbledor would've beaten him the first time around, and if not, Harry would've already defeated him. Similarly, this is why many other parts of The Sorcerers Stone are no longer applicable: they're incredibly stupid and don't fit with the message, theme, or modified characters of MoR.

The "quote" right before chapter 1 is about...

 * I can’t believe I didn’t think about it before; all the hints about hints in the author’s notes attracted attention finally. The other chapter-quotes seem well related to their chapter, but that one is a bit cryptic. Might it be a hint to the point-of-departure of the fic? A hint about the future story? What’s the tiny silver fragment? An assassin’s blade would work, but daggers don’t quite spill liters of blood. And whose blood spills? (Wizards don’t spill that much blood usually.) Who screams what? (It’s after the spill, so it’s not the spell that caused it.) Could it be when Voldemort spills the unicorn’s blood to reincarnate? (I can’t remember from canon when that happened, but IIRC it would have been around the time Harry started going to Hogwarts.) And why is it so important to hide it so in plain view?


 * The silver fragment is the buckyball transfiguration.

Voldemort is a Dark General.
Thus handily explaining Harry's dark side: his Yamiko got awakened and re-fused with him as part of some plan to make him more sympathetic to Voldemort. This also explains why he did something stupid like massacring the only dojo teaching the martial art he wanted to learn: being Yamiko, he has very limited self-control at best and being refused pushed it to its limit.

The difference divergence points and it's consequences
Just wanted to group the general know points where this universe is diferent from Canon, or at least inferred to be different. And speculate how it got this way.

Most witches are Yaoi Fangirls
Cause: Unknown/Unexplained
 * One possibility is that this is caused by Magical Britain being more tolerant of homosexuality than Muggle Britain.

Consequences: Dumbledore has less reasons to keep his crush on Grindewald a secret, but it is possible that it is a recent trend.
 * Gellert being a man is no longer a problem. Gellert being Gellert still is.

Narcissa died, Dumbledore claims to be the killer.
Consequences: This might be the reason why Lucius is a more caring father. It is a point agaisnt Harry trusting dumbledore

== The reason everyone is so much smarter in this fanfic than they are in canon is that their ancestors were all exposed to the Wold Newton meteorite from Philip Jose Farmer's Wold Newton family stories == It would handily reduce the points of divergence to one without contradicting anything.

Harry Potter is in fact Doctor Horrible
Doctor Horrible: The world is a mess and I just need to rule it.

Rational!Harry: ''I don't want to rule the universe. I just think it could be more sensibly organized.''

Close enough, don't you think?

The prophecy by Prof. Trelawny in chapter 21
"He is coming, the one who will tear apart the very-" is all we get to hear of it. It isn't about Harry or Voldemort, as they've both already arrived at Hogwarts. This leaves:
 * Remus Lupin, who arrives to teach the Patronus charm in Chapter 42. However, he hasn't been seen since Chapter 43, presumably left after teaching the Patronus charm, and didn't tear apart anything that we know of while he was there that we know of.
 * Could be a refen
 * Sirius Black
 * Real Voldemort, with Prof Quirrell not actually being Voldemort or only a fragment thereof.
 * It could also be that it is referring to a marked change in Harry. Harry has a mysterious dark side that is NOT always "present". It could be that this mysterious dark Harry is what is coming.
 * This could also apply to Voldemort. If he reveals himself to be Voldemort, this could be construed as "coming" even though he's already there.
 * Or it's referring to Mr. Hat and Cloak.

In this universe, the prophecy actually applies to Neville Longbottom
In the chapter where Harry asks Minerva about the prophecy, it is strongly implied that at the very least, the author has heard of this theory.

Quirrell is a self-aware, defective backup of Voldemort.
A Horcrux is not a soul fragment or a ghost. It is a backup of the brain-state of the caster, stored on some physical medium. (Think Joss's Dollhouse or Charles Stross's Glasshouse here, among other sources.) Restoring from this backup, however, requires a target to restore onto; with current levels of magic technology, that means a living human being's brain, which is overwritten with the restored brain-state.

Thus, it isn't creating a Horcrux that requires committing murder, but rather restoring from it: you have to overwrite some poor schlub's brain with the recorded personality. The reason that creating Horcruxes is still considered Dark is that creating one implies a prior commitment to kill someone (or have your followers kill someone) later on.

MoR!Quirrell is not Voldemort, as such. He's a damaged restore of Tom Riddle's backed-up brain-state, from early enough on that Riddle wasn't yet a Dark Lord; he was a Dark-leaning wizard who wanted to teach at Hogwarts but wasn't allowed to (possibly because Dumbledore's schizophrenia was still being successfully treated back then).

But the restore is defective, in two ways: First, the restore process didn't work right; it left Quirrellmort spending much of his time catatonic, and possibly left some fragments of Quirrell's original personality. And second, Quirrellmort knows he's a backup, specifically of a guy who got himself killed while trying to kill a baby. He's pretty appalled by that, for both the moral failings and the utter lack of style, and he's resolved to do a little better this time.
 * Or Tom Riddle was the defective, sociopathic backup of Quirrell, and Tom Riddle's purpose was to provide a common enemy to unite magical Brittan and force reform on the corrupt magical government.
 * This is my personal suspicion that Voldemort is a Starfish Character. The Dark Lord realized his rage was holding him back (as illustrated in his discussion about the martial arts) and cast it off as a different individual - cannon!Stupid Evil Voldemort, leaving regular Tom Riddle/Quirrel - who is no less evil, but not impeded by murderous rage all the time.


 * This is a interesting theory, but here a two alternatives: following canon, it looks like that the body-less Voldemort could possess anyone or anything, so maybe 1) The death of a person is required to adapt a horcrux in a suitable Data Storage 2) The murder is something to do with Death/Dementors, maybe a way to recognize the "wound in the world" and create a block over it?


 * If we go on this, the next step seems obvious--If Quirrel is a defective backup copy of Voldemort, Harry is also a backup copy, possibly one which hasn't been activated yet. The backup-ness is responsible for his weird split-personality thing and a lot of his cunning and occlumency-style talent. The "doom" is caused by them both being backups; Quirrel knew Harry was a backup as soon as he saw Harry or more likely suspected when he heard the story of Voldemort's death and confirmed it when they first met. Quirrel wants Harry to succeed, recognizing Harry as in some way "himself"; whether or not he plans to activate the backup Voldemort at a crucial time could go either way.
 * This theory makes a statement by Harry in chapter 69 quite ironic: "It's not like I'm an imperfect copy of someone else."
 * Assuming Quirrel is similar to Canon!Quirrel in that he accepted Voldemort believing that he was stronger and could use his power for good, this Quirrel may have downloaded Voldemort believing that he could use Voldemort's knowledge for good. And realizing he has a limited time, decides to teach Harry what he can before he is 'dead'. Quirrel probably has created a horcrux independent of Voldemorts, maybe just the one, indicating that he is not as badly damaged as the Dark Lord.

Quirrelmort's consciousness is at the Pioneer probe when he's in zombie-mode.
If horcruxing in this fic lets you transfer your consciousness between the host entities that are horcruxes, Quirrelmort's zombie phases are explainable by his consciousness mostly being elsewhere (either leaving a residual amount moving the body, or handing the body back to whatever vestige of its original mind is left). Quirrelmort seems to very much enjoy the view from the Pioneer probe, so that's arguably where he spends most of his off-hours (explaining the frequent zombie-quirrel periods).

If that was true, why would he let people see him that way? Better do 'zombie out' in private.


 * And risk getting caught once then forever being paid attention to? No, it's better this way: It's just what Quirrell does, and it can't be anything implicating or he'd have done it hidden.

Quirrelmort encourages Harry's occlumency lessons because it would invalidate testimony from Harry.
Testimony under veritaserum is invalid if the person testifying is an occlumens. It's considerably safer for Quirrelmort to give Harry potentially incriminating information if he knows that Harry would be unable to testify usefully about it.
 * This is almost certainly at least one of Quirrel's motives--or at least, a favorable side effect. Harry's musing about Quirrel 'using' him in a way that makes him stronger seems to apply.

Dumbledore wasn't fooled by Harry's false wisdom, but was playing him for his own purposes.
Per the author's notes, nobody in this fic ever holds the idiot ball. Dumbledore has demonstrated that he is skilled at spotting manipulation, skilled at performing manipulation, and capable of holding his own while playing the Game with experienced Slytherins. Therefore, in the discussion with Harry about death and the afterlife, Dumbledore didn't buy Harry's pattern-matched platitude wisdom, but pretended to do so for his own reasons (steering Harry's perception of him, steering the conversation, or some other reason entirely).
 * Agreed. Further evidence:  But what is Dumbledore's motive for this, I wonder?
 * Dumbledore is worried about the True Patronus because he noted its excellent jailbreaking property, and is fishing for more information about it. The confusion is due to Dumbledore's confusion between treating Harry as a student, whom he would certainly attempt to force more information from, or as a fellow powerful wizard due the assumption that they know what information is dangerous to share, as Quirrel is implicitly forcing in this scene.

Lucius Malfoy really was (at least initially) imperiused into joining the Death Eaters.
Lucius is really the sort of person who benefits from a corrupt government, since he knows how to manipulate the levers of power.

Quirrell is using the Elder Wand.
In the duel in Chapter 54, Quirrell is protected by a nigh-invulnerable shield that intercepts and holds any magic sent towards him. The effect persists when he's incapacitated, and goes away when he discards his wand. In canon, the Elder Wand makes its master nigh-undefeatable in a duel; this is consistent with the effects described in Chapter 54.


 * Nigh-Jossed in Chapter 57. Dumbledore almost certainly has it, which is consistent with canon.
 * More likely, he has Voldemort's wand. The canon connection between the wands still holds, causing strange effects when their magic comes into contact that can travel from the wands into the wizards themselves. Tossing the wand away weakened the effect the Patronal interception of his killing curse had on him. (Note that it would not have gotten rid of it entirely--there is a permanent bond between wizards and their wands, as we saw when Harry's was left too close to the Dementor.)
 * The Priori Incantatem thing apparently works between the two linked wizards, regardless of what wands they use. So, Quirrellmort could be using Quirrell's original wand. Also, Bellatrix tells them where she buried Voldemort's wand, so unless Quirrellmort guessed where she would bury it, he can't be using Voldemort's original wand (yet).

Bellatrix Black is a horcrux.
For Harry to undertake the Azkaban trip is understandable: it's already been established that he thinks it's a ridiculously inhumane institution, he's heard an argument from someone he trusts that an innocent (by some definitions) person is imprisoned there, he's had a person he trusts assure him that the rescue mission will very likely succeed, and he's idealistic enough to believe that the whole undertaking is worthwhile.

Quirrell, on the other hand, is neither idealistic nor altruistic. His scheme relied on someone he knew to be erratic (Harry), and he'd have known how badly it could go wrong (probably several ways in which it could do so). Quirrelmort wants to live forever, so taking this kind of risk would require a very strong reason to do so. Quirrell doesn't seem the type to care about Bellatrix's alleged domination, especially if Quirrell is indeed Voldemort (the one who imposed it in the first place). Therefore his motivation is something that hasn't been explicitly mentioned but that's overwhelmingly important to him (important enough to go on this hare-brained trip the instant he had access to someone whose patronus made it feasible, rather than waiting a couple of decades for Harry to gain more self-control).

The risk makes sense if Bellatrix was a Voldemort horcrux. If he still retains a link to her while she's stuck in Azkaban, it explains why Quirrell displays many of the personality traits Harry did when partly-Demented, and why he's especially vulnerable to Dementors (he's already under constant exposure through the quiescent link; direct exposure makes it far worse). As a horcrux, she can't easily be killed (and he likely wouldn't want to, as she'd contain a part of his mind-state even if it was inactive). Rescuing her becomes the preferred, and urgent, option.

Binding his soul to the person of the most powerful sorceress of the generation? That seems more secure than putting it in a damn cup.
 * "Bellatrix had once been, the most promising witch of her own generation, before the Dark Lord stole her and broke her, shattered her and reshaped her, binding her to him on a deeper level and with darker arts than any Imperius." -Ch. 52


 * Combine this with the 'Horcrux for each element' theory: Bellatrix is Death, Potter is new Life, Ravenclaw is Knowledge, the Basilisk is Destruction. What other elements could characters represent?

Bellatrix's dummy's potion is a Harry Polyjuice
Quirrell left a flask with bits of golden fluid in Bellatrix's cell. Polyjuice of Harry is one notable golden fluid in canon, so this might be some sort of clue purposely left to confuse the investigation: Was it Harry or was it Memorex?
 * Another canon golden fluid is Felix Felicis.
 * Jossed. The potion is an animagus transformation potion. Apparently it is a contingency play in case the fake body is discovered: Quirrell then intended for the aurors to think that Bella escaped by using the animagus transformation.

Quirrell was not Voldemort; he was the man behind Voldemort
The story he tells of the Martial Artists sounds a lot like a teacher sending an apprentice to learn something from a fellow master... and the student failing utterly.
 * This makes Quirrel's motives far more interesting. With this theory, he may be trying to find and destroy Voldemort's horcruxes. His rescue of Bellatrix might actually be a humanitarian mission (and/or a intelligence source to help him undo some of Voldemort's damage).
 * The Pioneer Plaque, of course, could still be Quirrell's horcrux.
 * This theory also goes along well with the theory that Harry somehow merged with Voldemort (see below).

When Voldemort "died", what was left of his soul and memories merged with Harry
. Look at the following quotes: "I had the strangest feeling that I knew him...Like meeting someone who had been a friend, once, before something went drastically wrong."
 * Upon meeting Quirrell, Harry thinks the following:

""Harry, I've seen a lot of abused children in my time at Hogwarts, it would break your heart to know how many. And, when you're happy, you don't behave like one of those children, not at all. You smile at strangers, you hug people, I put my hand on your shoulder and you didn't flinch. But sometimes, only sometimes, you say or do something that seems very much like... someone who spent his first eleven years locked in a basement. Not the loving family that I saw.""
 * And Here is McGonagall's initial impressionof Harry:

Sirius "escaped" from Azkaban by never going there.
When Harry asks if it's possible Sirius escaped from Azkaban, Minerva answers that nobody ever has. Harry speculates that a wizard prison might really be nearly 100% inescapable, and "The best way to get out would be to not go there in the first place." That line stood out to me at the time for some reason. But now, we have the prisoner in Azkaban who's constantly saying to himself "I'm not Sirius, I'm not Sirius." If we assume that's a prisoner who Sirius sent to Azkaban in his stead, we can deduce a little more from that. "I'm not Sirius" is not a happy thought, or the dementors would have eaten it. That implies that the person there knows he deserves to be there more than Sirius does. That points to Peter Pettigrew. How did Sirius make the switch? Perhaps in this universe, Peter and Sirius's animagus forms were each other? Seems like the wizard version of matching tattoos. Finally, I'm guessing that Sirius is still an inveterate prankster with a complexity addiction, and he's Mr. Hat and Cloak as well as Harry's guardian angel.
 * Seems unlikely that their Animagus forms are each other, due to MoR!Lupin still being a werewolf, and still friends with James, Sirius, and Pettigrew. The entire reason the Canon!Marauders became Animagi to begin with was to keep Lupin safe/others safe from Lupin during his monthly transformations, as well as to accompany him during that time. That said, it still seems highly probable that the person repeating "I'm not serious, I'm not serious" over and over is Peter Pettigrew somehow forcibly shifted into Sirius' appearance, due to his method of capture and lack of a trial.
 * Sirius (post-faked-death as Pettigrew) does seem like a likely candidate for Hat and Cloak as well, as he would have known about James' Invisibility Cloak, and if he's truly on Voldemort's side (or at least anti-Dumbledore), he has every reason to want Harry to distrust Dumbledore.
 * Also, waiting to see if Yudkowsky will work in a The Dark Knight "Why so serious?!" reference in regards to Pettigrew's assumed predicament.
 * In canon, when Black was free he did send Harry mysterious messages and gifts pointing to him being perhaps both Santa Claus and My Hat and Cloak. He does know all about the secret ways into and out of Hogwarts.
 * So now we know that Santa Claus is Dumbledore and Hat and Cloak is Voldemort, leaving not much room for an escaped Sirius in the story. At least not yet...

Bellatrix will be used in the restoration ritual from Goblet of Fire
Probably why Voldemort wanted her so badly, plus she was his most powerful warrior.
 * Cookie for you. This is Dumbledore's theory as well.

Quirrell was Voldemort's "seduction victim"
In Chapter 61, Dumbledore describes three ways Voldemort could return to life: "Dumbledore: Voldemort's final avenue is to seduce a victim and drain the life from them over a long period; in which case Voldemort would be weak compared to his former power."

If Professor Quirrell, before the start of the story, had been "seduced" by Voldemort and is now in the process of having his life drained, that would explain the episodes of zombie-like behavior and perhaps some other facts about his apparent possession by Voldemort. Having only a fraction of his former power would also explain why Quirrellmort wouldn't want to simply reveal himself openly and step back into the role of Dark Lord.
 * This isn't a WMG, it's the plot of Philosopher's Stone. The differences in Quirrell's possession are explained as increasing the challenge to deal with MoR Potter's increased abilities. There was an omake entry in one of the early chapters that pointed out how banal the first book would be with a rationalist Harry and a canonical Quirrellmort.

The Pioneer anomaly...
...was caused by the Quirrell's spell.

The author REALLY wants to introduce Luna

 * Luna is referenced frequently whenever Harry sees the Quibbler and wonders if she's really crazy or whether she's actually the Only Sane Man in the crazy wizarding world.
 * When Harry gets a note from someone asking to meet him, the note is signed LL and he IMMEDIATELY assumes that the note is from Luna, despite the fact that she hasn't even started Hogwarts yet.
 * In chapter 7, Harry claims to Draco that he's in love with Luna (and plans to marry her) in order to save her from Draco's revenge. By the time he actually meets her, either Harry or Draco will bring it up. Or maybe Luna if she really is a seer (which seems probable).
 * In Chapter 27, The Daily Prophet prints an article based on false evidence which claims that Harry is engaged to Ginny. The Quibbler responds with the headline "HARRY POTTER SECRETLY BETROTHED TO LUNA LOVEGOOD". Everyone sees this as ridiculous, but depending on how you interpret the scene in chapter 7, this one might actually be true.

Sybill Trelawney isn't a fraud

 * The author has stated that no character is allowed to carry the Idiot Ball, so one or more of the following will happen:
 * Sybill is a true seer who sees the future and remembers her visions. She and Dumbledore use this knowlege to prepare for it.
 * Sybill is prescient rather than a seer: she can only see the future insofar as people have made certain decisions in the present and she can see how those decisions will probably affect the future.
 * Sybill's antics about pretending to predict the future in tea leaves is just a test to see how the students react.
 * Alternately, she genuinely can see the future, but has been driven to the brink of insanity by it and now has great difficulty distinguishing the genuine prophesies from her own paranoid imagination.
 * Alternately, she is capable of actual visions, but believes that they are caused/based on what she taughts, there even might be a possibility that it will be used to show how many people can be decieved by they own "methods" but still find the right answer.
 * The class that she teaches is mostly concerned with the more useful aspects of Divination, i.e. Scrying distant locations in the present or the past.
 * The term Idiot Ball refers to a character's stupidity fueling a story line, especially if that stupidity is out of character or could be cleared up by a single question. A character who is simply incompetent all the time isn't necessarily holding the idiot ball.

Gilderoy Lockhart isn't a fraud

 * Since no one is allowed to carry the idiot ball, one or more of the following will be true:
 * He doesn't enter the story at all (boring, but possible).
 * He's competent and popular, but not overly conceited (boring, but possible).
 * He's is still vain and tends to overrate his own abilities, but he does have a few genuine accomplishments to back it up.
 * Alternately, he's just as good as he thinks he is, he's just an Insufferable Genius.
 * He pretends to be an incompetent fop so that his enemies will underestimate him.
 * He has a shrewd eye for public opinion and teaches Harry some valuable lessons on how to use fame to accomplish goals.
 * A character who is always an idiot isn't carrying the idiot ball, he's just an idiot. This would be boring to write, though, so I doubt it will happen in the story.

Gilderoy Lockheart is a fraud...

 * ... and within ten minutes of his first class, Harry will have demonstrated this unarguably, trussed him up like a pinata, and started leading the class on the path to killing Dementors.

The fic will not extend past Harry's first year.
Because Harry is just that awesome.

Quirrel's "Plot" to grant all three wishes...
Is to wait until just before the Ravenclaw vs Slytherin game, then convince both teams' seekers to agree not to go after the snitch until both teams have earned at least a thousand points, or better yet until they've both earned whatever the record number of points any house has earned in a year was. This ensures that one or the other will be guaranteed to win the house cup, and the other will still shatter historical records. It also guarantees the rules of Hogwarts Quidditch will be changed, since the exploit will become very obvious and nobody (least of all the other players who have to go at it for hours and hours) will want it used again. It's exactly the kind of plan Harry would come up with, so I won't put it past Quirrel either. It was even foreshadowed when Harry incredulously learned that Quidditch Points translate directly to House points. This ties up all three wishes so neatly, and fits the tone of the story in so many ways, that I am putting my name on it just so I can say I called it later.
 * Draco's wish was for Slytherin to win the House Cup, and Hermoine's was for Ravenclaw to win it; therefore, this does not tie up all three wishes, because it only provides for one of the two, but not both, to win the Cup. What's needed is for Ravenclaw and Slytherin to earn exactly the same number of House points, so that both of the two tied Houses can be argued to have legitimately won the House Cup.
 * The never-ending Quidditch match between Ravenclaw and Slytherin will be finally resolved by granting both teams infinite points. This will be the only way to guarantee a draw for the two Houses that isn't vulnerable to other professors upsetting the careful balance. Even Dumbledore won't be able to skew the results by awarding massive points at the last moment like how he does in the book. And deducting infinite points won't work, since infinity minus infinity is undefined.

Harry's Super-Powered Evil Side is Voldermort's "Darkness"
Quirrellmort knows that Harry holds a piece of his soul when Harry tells him about his dark side, and he has correctly assumed that it's mostly the part that held the madness from all of his dark rituals and that's what makes Quirrellmort's goals change/take a different approach than Voldemort's.

Because Quirrelmort is Voldemort, he will be allowed to stay beyond the usual one year as Defense Professor
Bet you Voldemort added a loophole when he cursed the job, just in case he ever did get it; he wouldn't want to be forced out of the Defense job by his own curse.

Also, I just can't imagine this fic without the Magnificent Bastard that is Quirrelmort.
 * No character is allowed to carry the idiot ball, and Dumbledore knows that Voldemort put a curse on the position. Dumbledore would have to be carrying the idiot ball to not figure out there was something up with Quirrel beating the curse, and Quirrel would have to be carrying the idiot ball to assume that Dumbledore wouldn't catch on.
 * But the teachers have already shown that they're putting up with Quirrel's obvious 'irregularities', because he's such a good Defense teacher. So long as he doesn't do anything too overtly Voldemort-ish or seriously compromise the school's safety, there's a good chance they might just put up with him.
 * Quirrel would still be holding the idiot ball to assume they'd give him a free pass just for being a good teacher, and Dumbledore reactivating the Order of the Phoenix just on the suspicion that Voldemort might be active again points to him taking Voldemort rather a lot more seriously than whatever oddities an average Defence teacher has that they feel turning a blind eye is a reasonable price to pay for having someone competent in the position.
 * "Quirrell" will return, but not as himself. He will come back as Gilderoy Lockhart, and his acting ability will make it work. Quirrelmort will need a new body anyway, as the Quirrell body is getting sucked of all life energy and aging noticeably.
 * Quirrel will be able to stay on past one year by having the class officially renamed Battle Magic... Or so he will tell Dumbledore. In fact, he will simply lift the curse.

"Vague Future Speculation for when MoR resumes"

Harry Potter will point out the "obvious reason" (at least to a muggle with sense) to Nymphadora Tonks why she (or any other competent metamorphomagus) can nearly instantly heal (not unlike a troll) just about any wound she receives in combat making her a very dangerous individual. This does not let her violate conservation of mass though... So at some point Tonks will receive grievous injury rendering her into a midget.
 * Jossed in the second chapter when Harry has his epic freakout when =McGonagall= turns into a cat. Both canon! and rational!Harry Potter universes trample all over Conservation of Energy rule, what with Conjuration, Transfiguration, Growth Charms, Vanishing spells, Polyjuice... the list goes on. We even know Metamorphmagi aren't bound by Co E, because Tonks shifts into Susan Bones who would be far shorter than her.

If the marauder's map exists (and is indeed something that students can create), then there is no reason to think that Hogwarts is not equipped with identity verifying aspects to its wards. This means that Quirrelmort has figured out a fairly powerful and comprehensive method for spoofing identity verifying spells and effects; this being almost certainly related to occlumency and the ability to "exist" as anyone Quirrelmort chooses "to be."

Muggle Electronics are not actually sensitive to magic in general; they merely react negatively when exposed to free transfiguration (the same way living creatures do), and this has been generalized in the wizarding world to become a mass prohibition on the use of magic around electronics.

Combining the previous two ideas: Harry will meet or become the first Magical Hacker in the world (only thing better than being a quantum hacker is being able to hack things at the level beyond quantum). Using free transfiguration on electrical components to make them open state or clear their memory; and leaving behind only corrupted sectors would make for a ghost of a hacker the likes of which the muggle world has never even dreamed about.

Voldemort is hiding in Quirell's wand
This explains why Harry's sense of doom decreases when Quirell snakifies (his wand is now merged with him, and no longer in Harry's immediate presence). It also explains why he throws away his wand when the killing curse and patronus interfere.

Harry's dark side is a very cynical adult wizard
But all the adult's personal memories have been obliviated. This explains the rememberall, McGonagall's observation, Harry's expectation that magic is real before he sees any, Harry's familiarity with the turn-left/go-down rule and the fact that Harry's dark side is not remotely childlike.

There are at least two .
The normal one is powered by forcing oneself to think about something other than death, and thus.

Harry's is based on the absolute rejection of death as a part of the natural order, and thus is able to.

Dumbledore, though, actually thinks of death as a part of nature, and does not fear it. Since he accepts death, and does not force himself to think of anything else, that could itself easily lead to an alternate version that.
 * This troper feels that this is unlikely; the story mentions that the reason why Dumbledore's patronus is so effective is because the patronus is normally powered by ignorance (give death no heed by focusing on happy memory and thus the Dementor is not able to utilize your faculties to achieve the semi-sentience that it does; remember that Harry commands the dementors away in Azkaban because after putting Belatrix down, whose expectations were initially stronger that they would hunt her, has a sufficiently strong expectation that they would leave) and he has been exposed to dementors so many times that the dementation effect has completely eradicated his (what would otherwise be natural) fear of death.

Voldemort didn't learn to make Horcruxes from a book.

 * Yudkowsky has made a big deal about "The Interdict of Merlin," but we now have two conflicting pieces of information:
 * Harry from chapter 23: "[It] stops anyone from getting knowledge of powerful spells out of books, even if you find and read a powerful wizard's notes they won't make sense to you, it has to go from one living mind to another."
 * Dumbledore from chapter 39: "Voldemort stole the book from which he gleaned his secret; it was not there when I went to look for it."
 * So either:
 * Voldemort learned the spell from a living wizard. (Or perchance ?)
 * Voldemort didn't create a horcrux (Possible if Quirrel isn't really Voldemort).
 * Alternatively: Roger Bacon's diary contains a secret which allows one to learn how to make a horcrux on one's own
 * It was given to Harry by Quirrellmort, admittedly stolen from the private collection of someone who supposedly only used it to impress his friends (noted in this wmg as sarcasm)
 * In chapter 39 Dumbledore specifies "the book from which he *gleaned* this secret"
 * After Harry invents the he is led to believe that with spells powerful enough to deal in The Interdict of Merlin, while their secrets cannot be spoken, one may leave clues towards how to discover them ala his letter to Hermione

The story will end in absolute disaster
The centaurs warned Lily that "the world would end if she were nice to her sister." They tend to be right. Desperate, with enemies on all sides, Harry will miscalculate the yield when conjuring an antimatter bomb or similar weapon.
 * All we know is that Petunia said that Lily said both that the world would end if she was nice to her sister and that centaurs told her not to. We don't know that the two claims are connected, and we definitely don't know that Lily wasn't just making them up. In fact, given the circumstances, it would be surprising to learn that her claims were true; I read it as a girl poking fun at her sister as opposed to an attempt at a legitimate excuse.
 * Also, given the author's known sympathies for certain specific "singularity"-style beliefs, it is possible that he has in mind something which the prophecy-centaur-Lily-Petunia telephone would consider the end of the world, but which is actually something good (or considered good by the author).
 * Sympathies, yes, but also an interest in working to reduce the risk of a catastrophe, should such an event eventually occur. The singularity is not safe.

Quirrelmort is the only one able to cast the "Star Light" spell
The view from the spell is of space with no major objects impeeding it is. no Sun, no planets. Since the Pioneer probe is and at the time of the story in remote space with no major objects within range then its logical to assume that the view of the "Star Light" spell is of what the Pioneer probe can "see". The unfortunate implication would be that Harry will never be able to learn the spell.
 * Merging this guess with another one above, maybe Quirrel regularly and consciously moves his mind to the probe when he has to wait for something, using star watching as a time killer. This would be consistent with his fascination for stars, the Horcruxed probe, the zombie mode AND the times when he is zombified (before classes start, for example, which can be boring). The Star Light spell could be just a spell to show other people what is around you. This may be too escapist for his character, though.
 * Maybe, but perhaps he is checking on the location of his Horcrux. It's wouldn't do to put a Horcrux where someone can't get to it just for it to fall into a star (probably as hot as Fiendfyre) or a black hole.

The following Quibbler articles are misinterpreted visions

 * The author said that Luna might be a seer. His example is: "Draco malfoy is pregnant" comes from something like "Light will plant a seed in the heart of the darkness"
 * "Sirius Black and Peter Pettigrew were secretly the same person": The Sirius Black in Azkaban is actually Peter Pettigrew.
 * "Harry Potter is secretly sixty-five years old.": Voldemort is exactly 65 years old at the time of the article. Either Harry is a Horcrux, or there's an even closer connection between the two of them.
 * "Harry is betrothed to Hermione Granger, Bellatrix Black, Luna Lovegood, and Draco Malfoy." It's not actually betrothal (probably), but Harry IS very closely tied to each one of them.
 * As of chapter 81 Hermione . It is possible that Luna or her father misinterpreted this as betrothal and at some point in the future.

Harry will at some point bite a professor who has bitten him first, probably Quirrel in snake mode.
This troper believes that it's going to be Lockhart. Harry doesn't seem fond of idiot teachers...
 * Because that line is too good not to be foreshadowing.

There will be a plot-significant Malfoy-Nott friendship.
Check out the parallels in chapter 67: Daphne duels Neville while planning to start a Romance with him, Hermione duels her best friend Harry, and Nott duels Malfoy. According to Word of Rowling, Malfoy respects Nott as equally noble and slightly cleverer--similar to how he thinks of Potter in Mo R. Nott might be Malfoy's pick to initiate into the Bayesian Conspiracy and start reforming Slytherin House.

The entire wizarding war was just a setup by Voldemort to take over the world in the body of Harry Potter.
Whether or not Quirrel is Voldemort, it seems clear that Quirrel (or maybe Q's wand) and Harry share some "essence". It seems unlikely that Quirrel is a Peggy Sue of future Harry (if so, where does Harry's dark side come from, and what disaster is he going back to avert? Fails Occam's razor). Therefore, the best theory is that both Quirrel and Harry's dark side are (fragments of) Voldemort.

It is clear that Quirrel himself is aware of the "doom" involved in physically or magically touching Harry, and Q hasn't shown any curiosity about that effect, so we can imagine that Quirrel has a (probably correct) theory about the cause.

If Quirrel is Voldemort, he is already extremely powerful and engaged in the real world, and his drooling/pass-out Quirrel periods seem to be a manageable nuisance. So he is probably angling for something more than simple reincarnation.

The wizard war seems to contain many idiot balls. Rather than just excusing these as being grandfathered in from canon, we could wonder if there's a deeper plot. Who benefits? The people who got hero status. Specifically, Harry Potter, or anyone who is believed by the wizarding world to be Harry Potter. (Also Dumbledore, but it seems clear that Dumbledore and Quirrel are enemies.)

So if Voldemort could use the horcrux to move from Quirrel's body to Harry's, that would explain a lot.

Not everything, though. For instance, why does Quirrel apparently care about Harry's education (unless he expects the "Harry" personality to survive as a subordinate, which would create a whole series of problems)? I guess that Voldemort might just want someone to optimize the world, and trust Harry to do a good job - but that also seems very out of character. So there are still problems with this theory, but since I've just found this page, I thought I'd put the out there.

A Horcrux is a sentient ghost.
It's very unlikely that souls exist in the MOR universe, so if Horcruxes are real in this story there must be some other explanation of how they cheat death.

We've already seen one form of "life" after death in the form of ghosts. However, these are shallow copies with little to no awareness and only a superficial ability to understand and interact with their surroundings. But this might be a result of the haphazard and accidental nature of their creation. A deliberately created ghost might be the equal of the person they were copied from.

Violent deaths are said to be one of the ways that ghosts are created, and one of the defining characteristics of a Horcrux is that they require a murder to create. It seems likely that a MOR Horcrux is created by killing someone in such a way as to produce a ghost, but then piggyback onto that process to imprint a copy of their own mental state. From there, the spell might also provide some way to do realtime syncing with the living creator. Or perhaps forming a redundant distributed consciousness with the brain of the creator and any other Horcruxes, to avoid having multiple copies of the creator running around.


 * The author made a strong case for the rationality of a character not believing in life after death or souls despite the evidence present in the books that the world does work that way, on the basis that the characters shouldn't be aware of those details. That, however, doesn't make it likely that souls don't exist in MOR itself. It isn't a trait of rationality to dismiss something because you don't want it to be true, and if there is evidence in the books that souls exist and MOR goes out of its way to explain how not believing in souls or the afterlife in spite of this is still rational, the correct response of a rational reader should be to accept that souls probably exist in MOR. You could probably make a good case that Voldemort would have wanted something based more in rationality than souls as his backup plan in case of death, and that horcruxes aren't based on souls or that Voldemort thought that they weren't based on souls, but I don't think you can make a case that souls themselves don't exist.
 * The existence of souls is strongly hinted by the observation that animagi don't need enough neurons to run their minds.
 * Word of Yudkowsky also mentions that there is, in fact, an afterlife, and therefore most likely souls, in the MoRverse, it's just that you can't prove the afterlife exists without actually dying yourself, and you can't rationally prove the existence of the soul.

Rescuing Bellatrix will turn out to be a giant mistake
because she's *evil*. Very evil. How she got that way doesn't matter. (Or so Less Wrong believes)

If wizarding society had the ability to make people nonevil by mind magic they would use it instead of Azkaban. It's never actually said that the origins of her psychosis will make it any easier to treat.

Quirell doubtless has a plan to protect himself from her, and likely to protect Harry, but not to protect the general public, because he doesn't value them.

Harry will become an animagius of an immortal creature
Harry will eventually decide to become an animagus but will rationally choose one with specific advantages. The animagus he chooses might be an immortal animal (like the basilisk) or it could be a future evolution of humanity to further increase his intelligence and power. He might have to be careful when explaining his reasoning to others since an evil rationalist wizard could animagus himself into Cthulhu.


 * In cannon, an animagus does not choose their form, it simply emerges based on their personality traits. So, I think a basilisk seems unlikely... That doesn't mean Harry couldn't be a Phoenix though.

Dumbledore delayed fighting Grindelwald because Grindelwald would have stopped Hitler
What better proof could there be that muggles were unworthy to rule themselves than the election of Adolf Hitler? Fanon usually holds that Hitler was Grindelwald's pawn, but here Dumbledore says Voldemort's atrocities were worse than Grindelwald's, and they certainly aren't on Hitler's scale. Once the allies took out Hitler without Grindelwald, and Grindelwald kept killing, Dumbledore knew he had to stop him.


 * Thus the Allies and/or wizards working in secret on their side are ultimately responsible for Grindlewald's defeat, if Dumbledore wasn't lying.

Harry will devise a standard metric unit of magic, for quantitative analysis purposes
We know that magic interferes with electricity - using this, it would be easy to devise a unit of magic defined as "the amount of magic it takes to disrupt a 1-volt circuit at a distance of one-meter". The "Merlin", perhaps.


 * This troper feels that this is unlikely. If the use of magic on an object interfered with the transmission of electricity in general, then it would result in self-transfiguration or similar body alteration rendering the person paralyzed, comatose, or perhaps just completely numb; if only temporarily. And without some specific reason to distinguish electronic components from everything which magic can effect without compromising its integrity there is no reason to suspect that this will be the case in Mo R. The world of Mo R that is being constructed is using as little fiat and rules inconsistency as possible. It is possible that whatever cosmic machinery governing magic interferes with electrical components, but with no historical precedent (i.e. ancient wizards having electronics and desiring to prevent its spread) you would need a specific law of physics that applied only to electrical components that magic interfered with in order to posit that magic interrupted electricity.
 * Small problem with your self-transfiguration theory. Neural impulses are chemical in nature. It might end up being the same effect, but the difference in origin keeps something that disrupts one process from disrupting the other. Thus, people in this world can use magic without disrupting the workings of their bodies.
 * Neural impulses are electrical in nature. Neurons do communicate with each other using chemical neurotransmitter, but the action potentials that run from dendrite to axon terminal and trigger the release of said neurotransmitters are electrical.
 * Magic stops muggle technology from working when in large quantities, excepting mechanically based technology such as clocks, such as Harry's watch and Minerva's grandfather clock. Whether it is the electricity in muggle tech that makes it vunerable or not, iffy considering the, Harry will discover what the true reason is and how to prevent it, and or how to cause the inverse, muggle tech that interferes with magic.
 * It's been observed that the quantity of magic does affect the extent of electrical interference (i.e Hogwarts greatly interferes with electricity, yet individual wizards can still use electronics); while the variables might be rather messy, it would still make a good starting point for quantifying magic, assuming the phenomenon is observable in reasonable quantities of magic and electricity. Honestly, I'm surprised Harry hasn't attempted something along these lines yet.

The point of divergence from canon is the Words Of Power And Madness being lost.
The Words Of Power And Madness ("Nitwit! Blubber! Oddment! Tweak!") cause the listeners to have a contagious Genre Blind and science/rationality blind affliction. Though the affliction is still quite common in MOR!verse, it's much weaker and effects less people to a lesser extent, because the words themselves cannot be repeated ever again.

Quirrel is a self-made orphan.
"It was long ago, and I resolved my parental issues to my own satisfaction." (Chapter 20)

"Go home, and enjoy your time with your families, or what's left of them, while they still live. My own family is long since dead at the Dark Lord's hand. I shall see you all when classes resume." (Chapter 34)

Harry has been plotting to steal the philosopher's stone all year.
It was mentioned to him before he even made it to Hogwarts. In canon, at least, it's public knowledge that Nicholas Flamel created one and that he's friends with Dumbledore. Harry tried to use transfiguration to cure Alzheimer's...would he really not have looked up life-extension wizardry? He knows Dumbledore's not on his side, so he's playing his cards close to his chest. It wouldn't be too surprising if the fic ended like this:

"Harry: Well, with my quest out of the way, the next six years at Hogwarts are going to be even more fun! Minerva: What about your quest to take over the world? Harry: That got a bit less urgent two weeks ago, when Muggle scientists announced they'd figured out how to synthesize the Elixir of Life. Minerva stared at him like he'd just turned a cat into her. Harry: You really should take The Guardian."


 * If no one is holding the idiot ball, I doubt Flamel is either, so even if Harry gets the stone, there is probably some drawback from using it, at the very least, the elixer at most extends life, and doesn't protect against violent death.
 * Another drawback is that everything about society assumes that people will die and be replaced by more people being born. And people will still desire sex, resulting in births. Unless we can sterilizes absolutely everyone on earth, there would be rapid growth of population, more than can be fed, so people would be dying but unable to die. In short, until we can generate unlimited food and energy, it would be unwise for more than a few people to be immortal. The only ones who have taken the Elixir is the guy that made it, who needs to live until society is ready for it, and his wife, so that the loneliness doesn't make his so bitter that he feels no one else deserves it.

The button Quirrell threw Hermione does something.
""Look, a decoy!""
 * Instead of playing the voices of the eight girls saying what they'd normally say, it will be a message from Quirrell, or a direct-to-Quirrell communicator, or that's what it would have done if she'd been 'worthy' of his tutelage.
 * It's a tracker.
 * It's a pipebomb.
 * It's an insidious mind-control device.
 * It's a decoy.

"Moody had once seen an addicted Dark Wizard go to ridiculous lengths to get a victim to lay hands on a certain exact portkey, instead of just having someone toss the target a trapped Knut on their next visit to town; (Chapter 63)"
 * It's a portkey!


 * It's support for her cause, it has some spell on it that will trigger when her hero-ing gets her in serious trouble.

Hermione is the enemy Voldemort will use in his resurrection...
See above re: button as portkey. It's not clear that Harry is Quirrellmort's enemy in this continuity, and the plot is making an awfully big point about Hermione being a hero for good in her own right, not merely a sidekick. It would make sense to use her blood for the resurrection, along with Bellatrix's flesh, to get the best possible combination of resurrection ingredients.


 * Hermione is not Voldemort's enemy, she is no one's enemy, . She will have to do something specifically and drastically against Voldemort himself to qualify.

...which will result in female!Voldemort(e), after using his mother's bone in the ritual
After all Moody's and Snape's clever fuss about the 'bone of the father', when there's another equally close relative's decayed corpse available. She was Riddle's magical parent, anyway.


 * This could happen if he used

Something really bad will happen to the students at Hogwarts, most likely involving Harry, and possibly involving Quirrel and Trelawny's Prophecy we only heard a part of.
"Everyone knows that nothing really bad ever happens to students in Hogwarts." This phrase or a variation thereof has been uttered by three different characters so far. If that's not Tempting Fate and Foreshadowing then I don't know what is.

Quirrel's willingness to bring Bellatrix into the open, putting innocent bystanders, Aurors and Harry in danger, just for the sake of a political scheme convinces me further of this. (Unless that was a Secret Test of Character for Harry, because it sounded too much like the Idiot Ball for him to actually carry it out after all the difficulties in breaking Bella out of Azkaban, and the possibility that he might use her in the Resurrection Ritual.)

Harry's Dark Side is a realistic portrayal of someone who suffered cannon!Harry's childhood.
I'm stealing the Adult Cynic explanation, because that's what made me think of this.

But all the adult's personal memories have been obliviated. This explains the rememberall, McGonagall's observation, and Harry's expectation that magic is real before he sees any.

The Dementor's Kiss is just ordinary death.
The Dementor's Kiss is said to destroy a person's soul. Souls are not observable in MoR, and there is no observable afterlife (if there is one, nobody has ever looked into it or received communications from it). Thus, there's no way to tell the difference between somebody's soul being destroyed and the person simply dying. Since a Dementor is just a bit of self-propelled death, it makes sense that the thing that a Dementor does to someone is simply the thing that happens when they die.


 * According to the Harry Potter Wiki, a person that suffers the Dementor's Kiss appears to be in a Persistent Vegetative State. So, well, if you discount the whole thing about souls, the Dementor's Kiss would indeed be something very much like ordinary death: the killing of somebody's mind while leaving the rest of the body intact. ("The rest of the body", in this case, would also include the parts of the brain responsible for breathing and other automatic functions.)


 * Harry's theory is that both are correct. The Dementor's Kiss is just ordinary death, and it's perfectly ordinary for death to result in Cessation of Existence.

The Marauder's Map malfunctions are due to Time Turners and Voldemort.

 * Fred and George believe that the map is actually part of the security system of Hogwarts.
 * The Marauder's Map is noted to have two malfunctions by Fred and George in Chapter 25. One is intermittent, the other doesn't change. The intermittent one could be the fact that Harry shows up in multiple places at once when using his Time Turner. However, other Time Turner users would do the same, and we know Dumbledore and Millicent both have one as well.
 * The other malfunction could be that Quirrell shows up as both himself and Tom Riddle. Or, since the Map may have been created by Salazar, Voldemort may know some means of confusing or blinding the map.
 * Wasn't the Marauder's Map created by the Marauders? Maybe I missed something in Mo R, but in canon, we certainly know that the drawing is Lupin's work. (I'm with you on Tom Riddle showing up on the map, though.)
 * Perhaps the map never shows a name for Quirrell, if it truly does work with Hogwart's security. Dumbledore stated that he'd identified Quirrell to the Hogwarts wards as simply "the Defense Professor". So that might be how he's labeled on the map. On the other hand, Dumbledore didn't know that Moody wasn't Moody in canon, but the map did....


 * Alternatively, the Time Turners wouldn't cause a 'malfunction', since they're a known commoditiy, several people have them. However, The Invisibility Cloak (note important capital letters) could certainly cause a malfunction in that Harry Potter occasionally just drops off the map entirely for no discernable reason.

The lack of Voldemort's face on the back of Quirrel's head is because Voldmemort is always off in by himself.

 * Quirrel is only balding because the possesion hasn't had a full amount of time to take effect as Voldemort's spirit spends most of its time inside his special Horcrux, and Quirrel's alternating periods of a zombie state and a lucid state are explained by his soul being destroyed by a Dementor's kiss to more fully prepare him as a vessel for Voldemort, whose possesion acts as Quirrel's lucid state.

Sirius is inside of Hogwarts, or has some way of seeing inside it, and is aware of most of what goes on inside it.
This is in accordance with a couple other WMGs. After Peter Pettigrew betrayed the Potters, Sirius Black went after him, and then was framed for the crimes Peter actually committed. However, James had given Sirius the Cloak of Invisibility before he died, and Sirius was able to use this to make a Clever Plan to switch him and Peter's positions; Peter ended up in Azkaban with the Wizengamot being convinced that he's Sirius (hence "I'm not serious...") and Sirius walked somewhat free. He then told Dumbledore everything that had happened, and Dumbledore helped set up Sirius in 12 Grimmauld Place. Later, when Harry started at Hogwarts, Sirius came back and is hiding somewhere in the castle or the grounds, under Dumbledore's protection, probably as the big black dog. Sirius was then able to pass along the Invisibility Cloak to Harry as Santa Claus, and then also gave Harry the card Portkey that takes the user to somewhere in London (according to Quirrel.) Also, James' Rock is some kind of surveillance device that allows Sirius to keep tabs on Harry. As well as this, Sirius is the one who sent Hermione the note in Chapter 72; he overheard Harry and Hermione talking about the bullies because the Rock was with Harry.
 * Oh, and for the sake of completeness, he probably has something to do with Mr. Hat And Cloak; perhaps James was known as this because of the Invisibility Cloak, and he is now taking on his name.
 * I expect Sirius is at large like the original troper says, but it's not clear he's friends with Dumbledore. As Santa Claus, he tells Harry not to trust Dumbledore with the Cloak. Repeatedly. Honestly, if he's innocent, Sirius has not been exonerated in anyone's mind--he didn't even tell Lupin, his homeboy--and Sirius may suspect Dumbledore's plotting had something to do with James and Lily dying. James' Rock is doubtful to have anything to do with Sirius due to the amount of information he would have on Harry... which doesn't come across in his letters as Santa Claus (he thinks Dumbledore still doesn't know about the Invisibility Cloak). He's also the most likely candidate for the "intermittent" problem with the Marauder's Map due to his occasional trips into Hogwarts as Santa Claus.

Harry can't become an animagus.
His "inner animal" is simply a human being, making the process redundant. He'd wibble a bit and look the same.
 * I disagree with that. Patronuses and Animagi are two different things. Patronuses reveal your "inner animal" but a wizard becoming an animagus can assume any form during the preparations. You choose what form you want to transform into, it's just that most if not all of the characters who become animagi have some kind of Meaningful Name thing going on, except for "Meaningful Form." Therefore, if Harry wanted to become a snake he easily could, even though that's not necessarily a reflection of his personality.
 * If Harry can choose what animal to become, he'll be as munchkiny as possible. Does God count as an animal?
 * Patronuses quite don't reveal your inner animal, just whatever animate being has the most meaning for you. At least, in Rowling canon. That's why Tonk's Patronus changed from whatever it was before into Lupin's werewolf form. They can also, at least in Rowling's canon, take on the form of magical creatures. Presumably, though, if Tonks became an animagus, her Animagus form would not be a werewolf and ditto for the historical Wizard whose Patronus was that of a Giant. However, of the two characters in Rowling canon who were able to use both the Patronus and Animagus on "screen", they did match.
 * It seems to me that your Patronus is your father-figure--it comforts and protects you. PATRO-nus for PATER-nal.
 * Nice thought but not exactly. Patronus is a whole different Latin word, literally translated patron or (the reason it's used for this charm) protector/guardian.
 * If his inner Animal is a Human Being, then that would either give him powers like Tonk's or make him an enlightened, or perfect human, like how the author of One Piece said would happen if a human ate the Human-Human fruit. Either way he would get some unique power from it.

Dumbledore, Quirrel, Voldemort, Santa Claus, and Mr. Hat and Cloak are all the same person.
I'm already assuming that Quirrel == Voldemort == Mr. Hat and Cloak; those seem reasonably well-supported. Zabini thinks H&C is trying to stir up trouble between Quirrel and Dumbledore, but it seems likely that he IS Quirrel, so that's impossible; Even if H&C isn't Quirrel, Quirrel would never be tricked by H&C's shenanigans with Zabini, so H&C's actions are to trick Harry, not Quirrel. And what better motive for making Harry think Dumbledore and Quirrel are at odds than to hide the fact that Dumbledore and Quirrel are the same person?! Sure, we see them together, but we already know they have a time machine.

S.P.H.E.W, will, by the end of Hermione's tenure, evolve into Hogwarts' Absurdly Powerful Student Council
This is how these things get started.
 * It is still possible if they decided to take a more subtle and or constructive approach, maybe they will organize the students to protect themselves if the new precautions don't work and thus grow to become such a council, whether the adults authorize it or not is another thing entirely.

Roger Bacon's Diary is a Horcrux
And Rita Skeeter was the sacrifice necessary to turn it into the same. Yes, I think Quirrellmort is enough of a Magnificent Bastard to actually surreptitiously make a horcrux onscreen. He's certainly clever enough to make it from an object that has emotional weight to Harry rather than to himself.
 * In Canon making a Horcrux doesn't just require a murder but also 'something awful' of an unspecified nature (JKR knows what this is and apparently when she told her editor what is is it made him feel physically sick). It is possible that Quirrelmort did all of the appropriate Dark Rituals and such beforehand so that it only required Rita Skeeter's murder to finalise the Horcrux's creation.

Snape will switch back over to Voldemort's side.
In canon, Snape is on Harry's side because he's still in love with Lily. After Harry's "advice" conversation with Snape, Snape tells Harry "what your mother saw in him was something I never did understand until this day." If Snape does accept Harry's answer — that Lily was shallow and unworthy of Snape's affection — as the truth, he may get over his love for Lily, and when that happens, he may decide that he was happier being a Death Eater after all.


 * It's unclear whether this was rendered more or less likely by chapters 76 and 77. In Chapter 76 we learn that Snape's showing up at the last SPHEW battle was not condoned by Dumbledore, and Snape went to considerable lengths to keep him from finding out about it. Snape seems to be going rogue. On the other hand, in Chapter 77, Snape still believes that his life was ruined when he told Voldemort about the prophecy, indicating that he's not exactly over Lily yet, perhaps. He dwells on the meaning of the prophecy, his motive for which is unclear. But if he's starting to compartmentalize his despair, and if he decides that he doesn't care which "ingredient" vanquishes the other so long as the "cauldron" doesn't burn up, he may indeed have decided to switch allegiances again.
 * Same troper as above here, and after rereading and thinking about chapter 77 some more, the only reasonable conclusion is that Snape will go back to the dark side (or at least that he's strongly considering it). Chapter 77's name is "Sunk Costs", which can refer to the phenomenon in business of throwing good money after bad. In this case it seems to refer to Snape's feelings for Lily, and only makes sense as the title if the chapter represents Snape deciding to stop throwing good feelings after bad and to finally get over Lily. The clincher is the fact that he . He would not have done that if he were still saving himself for Lily's memory, and it represents the moment where he starts his post-Lily life.
 * Sunk costs don't necessarily mean you have to stop doing what you're doing though. Just that you must sit down and reevaluate your actions. It just means if Snape does choose to keep working against Voldemort, it will be because he's judged that the good thing to do, rather than out of a Freudian Excuse.

Dementors are the cure to entropy
The Dementors existence and the lack of immortality of the decedents of the late-Atlantis are both necessary evils.

The source-of-magic is always being used and would be used up (law of conservation of energy) except for the dementors who break down and absorb all adjacent magic-matter-and-energy. The collected energy from the magic-matter-and-energy absorbed is returned to the source-of-magic. The reason no Atlantean is immortal is because making someone immortal will break the law governing the artificial source of magic. (The law is probably related to how harry's happy thought destroyed a dementor) Harry will likely find a way around this loophole, and will send the dementors into areas of high entroopy to absorb enough energy for Harry's future reorganization or "godhood" via Harry's wand. In fact, Harry may create more dementors after he realizes this to help him in his attempt to rewrite the rules of the universe/source-of-magic.

Now this makes the hypothesis that magic is diminishing very real if harry continues to kill "death" or rather the "disorganization and absorbtion vehicle" of the source-of-magic. Disorganization is just as chilling as death to an atheist.

Voldemort's bones will be impregnated with potions
Snape remarks to Moody that he thinks bones impregnated with a certain muggle substance, LSD, will have permanent effects. Voldemort will find a way to get a bottle of Felix felicitus to do the same thing to satisfy the first law of fanfiction. If the protagonist is a Jedi, then the villan gets a deathstar.

Harry will discover the afterlife, conquer it, and establish free travel and trade between it and Earth
It's been established that an afterlife exists in the Harry Potter universe, even though it is very well hidden. Perhaps even intentionally hidden. It would make sense that whatever created the Source of Magic also created the afterlife at the same time. Perhaps Atlantis itself is both the Source of Magic and the afterlife, and it was deliberately "erased" from Time as part of the process that established its function.

Whatever the mechanics, it would be a HUGE deal to mor!Harry for the same reason he was freaking out about parsletongue. The population of the afterlife would be FAR FAR greater than the population of Earth. In his ultimate quest for immortality, it would be a drastically unconventional resolution for him to realize that everyone is already effectively immortal, but trapped in a previously undetected elsewhere.

So Harry's mission becomes the liberation of the afterlife, and devising a way for people to travel both directions, hopefully without destroying a body in the process.


 * If there is no afterlife Harry may end up making it.

Quirrel's "Plot" to grant all three wishes... another view.
We don't know exactly what Draco's and Hermione's wish really were. " 'Mr. Malfoy,' said Professor Quirrell, 'your wish is for... Slytherin to win the House Cup.' " and " 'And for Miss Granger...' said Professor Quirrell. There was the sound of a tearing envelope. 'Your wish is for... Ravenclaw to win the House Cup?' " if instead of those exactly words Quirrell is tell the audience their simple joint wish of " I wish my house would win the house cup." So to solve the three wishes he somehow forces the creation of a new house and both Draco and Hermione get sent there along with Harry of course. This forces the current Quidditch Cup holder to play against the new house to maintain the title during which the new house plays keep the snitch away from all the other teams players. Making the match go for days forcing the rule change at Hogworts. Together Harry, Hermione, and Draco plus the points from winning the Quidditch Cup and of course whatever point Dumbledore awards them at end of are enough to take the house cup. This is will hurt Harry's plans to redeem house Slytherin but he can figure out a different way.


 * Alternately, Slytherin and Ravenclaw houses must merge.


 * Alternately, Draco and Hermione are assigned to the same existing House. Either Draco no longer fits in with the Slytherins, or important people get convinced that Hermione's really been chatting up Slytherin's ghost. Quirrell could work it either way. It's remotely possible they both could get moved to Hufflepuff or Gryffindor (very unlikely for Draco). Flitwick has used House reassignment as a threat, so a Head of House has that power--I feel he'd have to coordinate with another Head to move a student, however. Or Quirrell gets Dumbledore to do it since the Headmaster does whatever he wants. I see Draco being the easiest to move AND the trio ends up together, which would be an interesting storyline twist as the original troper suggests. Well spotted by the way, their wishes definitely could both read "my House"... of course they never specified what YEAR their House would win the cup. Quirrell takes pride in his plots, though, I don't expect that he would use a copout like that.


 * Alternatively, Slytherin and Ravenclaw could just tie for first place.
 * The major difficulty for Quirrell will be convincing Dumbledore not to upset the tie before announcing the winner (like in canon). Also, is a tie a win? Would Quirrell choose such a complex plot? Would Elizier use the same plot-twist twice?

Harry will become god by using the Comed-Tea and his evil side..
He states in chapter 12 that the Comed-Tea makes you do a spit-take. He thinks that if he could use a spell to change his sense of humor so that only becoming omnipotent would be worthy of a spit-take. Note that such a spell (probably) does not exist. We later learn that Comed-Tea works slightly differently, but the premise is the same (drink tea -> spit take).

We also saw his evil side in Chapter 44. It appears utterly emotionless, with no sense of humor, and responds in no way other than "you should die". There are a few things he could respond emotionally to, but there are few of them. Assuming he drinks the tea in this state, he will be forced to do a spit-take, which will lead to something insane happening, possibly propelling him to godhood.

Alternatively, it will cause a paradox and destroy the universe.
 * Jossed. Comed-tea uses non-linear causality: it triggers a desire to take a sip a second or so before a comedic occurance. Harry figures it out somewhere around chapter 13 (I don't remember exactly).
 * Wasn't that theory also jossed by Professor McGonagall. And even with non-linear casualty, he would feel the need to drink shortly before the time when he (theoretically) becomes god.
 * "The empty thing laughed at that, for it had retained the capacity to be amused." Harry's dark side still has a twisted sense of humor.

This story is secretly a Massive Multiplayer Crossover
There are quite a few spells and magical items that are closer to Dungeons and Dragons than regular Harry Potter. The Comed-Tea is probably from Xanth, Mr. Hat and Cloak is a Sidereal, and there are clearly more people from other universes running around.

Rather than stealing fame from the unwilling by magic, Gilderoy Lockheart will steal it from the willing by reputation.
Anyone who carries an Idiot Ball in canon has to have their intelligence upgraded here, and canon Lockheart's living is pretty shaky. So what if instead of relying on memory charms and deception he just relied on people already wanting him to take the credit? Like in canon he makes a point of traveling to meet upstart heroes before word gets out, but he doesn't have to hide it because this is in fact a regular thing he does--many of these interviews end up transcribed in his books without serious alteration. But if he detects that the person would really rather not have their fame, he offers them the chance to get rid of it. A willing hero can easily help him find and obliviate and/or swear to secrecy all loose ends who know the truth (the latter arguably much better since there are canonically spells to make such a promise unbreakable which won't leave behind as much suspicious residue as memory charms, but with obliviate for the truly unwilling), along with themself. I'd expect that after a point he'd also start getting approached by undercover aurors and other people who want it getting out that such and such a thing has been done but can't afford to have their name on it. Either way, everybody wins and noone's been harmed (except the occasional obliviated witness, but he'll claim it's for the greater good). He'd probably have considerably better book knowledge of any magic involved in any of his "exploits", both since he's less of an idiot and because he can properly ask the heroes for help, but he wouldn't be as proficient with Obliviate since he wouldn't be using it as a first resort.

The interesting part is how he reacts to Harry. He wouldn't be stupid enough to dream of inserting himself into a story about canon Harry MOR Harry's exploits, since it just wouldn't fit. If he met canon Harry he'd have one set of interesting interactions since the "encourage him to embrace his fame" thing would have to be reevaluated by the author--but he'll have an entirely different dynamic with MOR Harry who is already exploiting his fame for more mileage than both Lockharts combined. Unfortunately any lesson he could likely give Harry would be about a year too late, and Harry might teach him a thing or two. Ultimately I'd imagine MOR Harry agreeing to keep his secret should it get out.

About the Hermionie tip in chapter six:
As his hand touched the back door’s handle, he heard a last whisper from behind him. "Hermione Granger." [...] There was no answer, and when Harry turned around, Mc Gonagall was gone.

The person who told Harry to look for Hermionie was:
 * Dark Lord Harry, travelling back in time.
 * Hermionie, travelling back from a Dark Lord Harry timeline.
 * Quirelldemort, because he planned things out ahead earlier than we thought
 * Mr. Hat and Cloak, because of a Gambit Roulette we don't know about.
 * Actually Minerva and the writing was just to confuse us.
 * Actually Minerva, and the writing was intended to be clear without sacrificing the form of dramatic prose.
 * Hagrid, because why not.

The ritual in Chapter 74 completely did work that way.
It actually did permanently sacrifice Yog-Sothoth to briefly summon Harry Potter -- or, to be specific, to briefly summon Harry James Potter-Evans-Verres. The ritual retroactively turned the canon-verse into the MoR-verse. And the life of a mortal is pretty brief, in the grand scheme of things, even if he does live long enough to do all the things he listed in chapter 39.
 * Possible evidence for this theory is a floor in chapter 75, which is tiled in pentagons. While it's true that you can use irregularly shaped pentagons to tile a floor, you need some sort of Alien Geometries to get regular pentagons to tessellate.
 * Exactly what chain of events would ever lead Canon!Tracey Davis to ever utter those exact words described in Ch.74? Also, I wouldn't put it past Hogwarts - even Canon!Hogwarts - to have such a pentagonally-tiled corridor.
 * Oh, by the way, I'll just leave this here... Not exactly regular, but close enough, neat and symmetrical pentagons.

Harry's intelligence is the result of accidental, underage magic
It is stated in Harry Potter canon that Muggleborns routinely endure incidents with uncontrolled, accidental magic before they'd receive the Hogwarts enrollment letter -- to the point that some Muggle families are relieved to receive it, since it finally explain what has been going on. However, no such history of incidents is mentioned for Harry in The Methods of Rationality at all, to the point that McGonnagal has to make a demonstration to the Verres. The explanation for this is, since Harry was raised at as rationalist and that magic is so unscientific, he unconsciously suppressed such instinctive magic manifestations and internalized them. Thus, this increased his intelligence to child genius levels, way beyond that of Canon Harry, and also explain why he inherited some traits of his adoptive father, like the ability to always retrieve the right book he's searching. This had some unknown side effects, though, like his non-24-hours sleeping pattern, and maybe his fractioned personnality too.

How the animagus transformation might work.
Harry freaks out over the animagus transformation violating a lot of things he knows about physics, but ever since reading about the teacher that warmed one side of a metal plate and turned it around, I've been thinking that maybe Harry was making a related sort of mistake. Maybe it doesn't violate Conservation of Mass afterall.

I think a critical piece of evidence here is what does the animagus transformation feel like?

Have you ever woken from a dream in which, at the point of waking, your dream-body is in a very different position than your actual body? It's a very interesting experience, there's no sensation of movement or recalibration of your motor functions; indeed it doesn't feel like anything and your brain doesn't update on the position of your limbs until you actually try to move and get new feedback that overwrites that from your dream.

Would an animagus transformation feel the same way? I think it would, because the only way I can conceive of mass-variable shapeshifting is if all the matter of both states exists simultaneously as a single unchanging structure in 4 spacial dimensions.

Imagine for a moment that our universe expressed only 2 spacial dimensions instead of three. Now imagine that, living in this universe we encounter a three-dimensional object, such as a sphere, intersecting our 2-dimensional universe. If the sphere moved in the 3rd dimension, from our perspective in the 2-dimensional universe what we would perceive as an ordinary circle would appear to change size in violation of Conservation.

(Note: The theoretical 4th dimension I'm referring to here is NOT Time any more than the 3rd dimension is Time in that 2-dimensional universe; I'm conceptualizing purely in the idea-realm of spacial dimensions, here.)

This rather neatly explains the animagus transformation: a 4-dimensional object is merely MOVING so a different CROSS-SECTION happens to intersect our 3-dimensional universe; it's not changing shape or mass at all, and the animagus can go on thinking like a human because the human brain is still there, no less a part of the 4-dimensional physical structure than it is when the human-shaped part of the animagus is intersecting our universe.

This doesn't explain TRANSFIGURATION, in this specific case of the creation of the 4-dimensional object in the first place, or in general, but it may explain mass-changing shapeshifting like animagi (or the Wolves in Luminosity for that matter).


 * I was thinking of animagi in terms of Alan Moore!Miracleman, specially when it was mentioned that when Bella was imprisoned "her animagus form was destroyed".

Azkaban Island is the last remaining chunk of Atlantis
Dumbledore implies that a temporal-engineering disaster destroyed Atlantis. Azkaban is a time-travel anomaly. It would be neat. Would be Jossed if that property of Azkaban was created by modern wizards as a part of constructing the prison. (I also don't have much confidence in it because I think I recall Eliezer saying he added the Atlantis reference to make an unrelated point. But he's not above retconning.)

The Timeturner limit of six hours is enforced by a time police
They force anyone who would cause a paradox to Trick out Time, and thus prevent their own paradox, and the limit is enforced to make the job of policing time easier. Thus Harry's Worries about time being consistent despite time travel is explained as being and artificial condition created using multiple worlds theory and branching time lines, anytime time you use a time turner you create another timeline, this time police keep every not internally consistent, Tricked out Time timeline from interacting with the alpha timeline, It is possible that this is done by atlanteans, Their civilization was removed from time either by these police for mass time crime, or they removed themselves from the timeline when they created time travel and not they treat it as their responsibilty to police time, as they exposed it to tampering.

This version of the Potterverse it's actually the Stargate Verse
We have several mentions of Atlantis, which would be THE City-ship of Atlantis, Also Harry discovered that a wizard is some one with a specific Gene, IE. the ATA Gene. Magic would be thus some Advanced Technology left by the Ancients in Earth OR After They ascended they played with the laws of physics so humans could some day beat Entropy. in the end when harry starts contacting the Scientific community to get help on Magic research he will be contacted by Stargate Command wich would make the connection of the ATA Gene.

Voldemort was Raised By Albert Einstein
If Harry had a happy family life, and was raised by nice Muggles, then the concept of Harry and Voldemort being foils for each other no longer works. In order to maintain the concept of Harry and Voldemort having a similar starting point, but ending up at completely different points, Voldemort must then have been adopted by a good Muggle or good Muggle family (or else been in an orphanage where he wasn't mistreated). This could also work as a nice Start of Darkness, since Quirrell's horror at the muggle invention of use of nuclear weapons it very much like Einstein's own.
 * Mark Oliphant might be a better match, since it would have to be a scientist who lived in Britain.

Harry will find out about the Philosopher's Stone and then flip the **** out.
If Harry really hates death with a tenth of the fervor Eliezer does, he will lose all composure when he finds out that the cure for death exists and is in use by just two people in the whole world. He will first flip out on Dumbledore for conspiring to keep it hidden. In a rage he'll ask Dumbledore how many doses of the Elixir of Life he's had, and will maybe cool off a little when Dumbledore assures Harry that the answer is zero. Harry will be calmer, but colder, as he demands an audience with Nicolas Flamel. Then, either Dumbledore will talk to Harry about how no one should have the power to decide who lives and who dies, and how it's better for no one to have the elixir than for Voldemort to have it, or he will take Harry to see Flamel and the same sort of conversation will happen.

James Potter killed Voldemort with the Potter Family Rock
Accio meteorite!

Quirrell will have Hermione killed as Harry watches.
Quirrell's goal is to make Harry go permanently over to his dark side. He tried once already with the Dementor. Harry's light side would have been history then, had Hermione not saved him. Okay, so if Hermione is one of the only things that can bring Harry out of his dark side, what would happen to Harry if he watched her die slowly and painfully? Especially if it were made to look like Dumbledore's doing?

Or maybe it will merely look like Dumbledore refused to help. The story's trigger warnings are next going to be updated when a chapter called is published. Perhaps what will be Hermione's torture and/or death.

Lucius Malfoy will learn about Draco's Patronus when Draco uses it in an emergency to summon Lucius to save Draco and Harry.
Draco doesn't want Lucius to know he can cast a Patronus, but sometimes, ET just has to phone home.
 * Most likely he found out when he gave Draco veritaserum after the attempted murder.

Harry will become a phoenix animagus
From chapter 42, when asked what his patronus will be:'' "Peregrine falcon," Harry said without hesitation. "It can dive faster than three hundred kilometers per hour, it's the fastest living creature there is." The peregrine falcon had been Harry's favorite animal since forever. Harry was determined to become an Animagus someday, just to get that as his form, and fly by the strength of his own wings, and see the land below with sharper eyes... ''

The phoenix is faster (instant teleport!), immortal (resurrection?), and important emotionally to Harry (Fawkes). It can fly, and even seems somewhat sentient. Anthony Goldstein got the peregrine falcon first, and there appears to be an unexplained limit of one character per animal, so it's likely Harry can't have it. Rethinking his choice will lead to the only logical conclusion consistent with his desires in a spirit animal. Phoenix!


 * Problem: Dumbledore already has a pheonix patronus.


 * That's not a problem. One's patronus don't necessarily have anything to do with animagus form.

The prophecy Dumbledore told Snape was ENTIRELY made up.
Why wouldn't it be? Dumbledore and Minerva heard a real prophecy, which made it clear that Harry and Voldemort would be enemies for life, the dark lord would mark Harry as an equal and Harry would discover "a magic of which he knows not". A sufficiently cautious dark lord would recognize that the trope coming and avoid that kid like the plague, sending a minion to do it and preparing for his failure. But since Dumbledore was leaking this prophecy anyways, might as well hedge his bets and give him a prophecy that clearly implies that striking Harry while young will work. And he'd HAVE to do this for the same plan to work had it mentioned Harry by name, since otherwise Snape would never have just handed over the prophecy. For that matter, have we heard the full prophecy in MOR-verse?

Mr. Hat and Cloak is a time traveller.
My first WMG, and I post this only out of sheer, stupid, blind confidence in it. When asked, "Just what do you think you know, and how do you think you know it, anyway?" Mr. Hat and Cloak responds, "Time -" [The voice seemed to catch itself] "Time enough for that later." Sounds like he was stumbling over the word time travel, huh? It would explain a lot. And it opens up a whole range of possibilities of who it could be. And it explains why Hermione recognized him. And. . . wow. This one's exciting.

Mr. Hat and Cloak is Ms. Hat and Cloak.
It's strongly implied that M Ha C is a time traveller (see WMG directly above). Also, Millicent said that she was feeding Millicent hints. Also, the confrontation with Hermione takes place on a witches-only staircase. It's a pretty damn strong case.

Harry is going to become the next Dark Lord.
If Quirell is Voldermort, then Harry is going to be terribly conflicted durring their battle, since he was his true mentor. But Harry is likely only going to be conflicted for about a fraction of a second. By then it's likely that Harry would have heard the prophecy, and knowing that he could never stand by Voldermort's side since they were destined to kill eachother, Harry will be forced to kill Voldermort.Plus, Voldermort killed his true parents. But Voldermort's ideals of immortallity will live on in Harry, who will replace him as the Next Dark Lord, beleiving himself to be a Light Lord.

"I'm sorry it had to end this way, Tom. You were absolutely right. But you killed my parents, and for that you'll have to die."

Voldemort is a Ravenclaw
Voldemort is smarter than Harry. Harry is far more ambitious than Voldemort. (Harry is trying to become God. Voldemort is trying not to die.) Harry is a Ravenclaw. Voldemort can't possibly be a Slytherin.
 * Better yet, Voldemort is a Hufflepuff. It matches the Gryffindor/Slytherin rivalry and Voldemort was a Muggle orphan, meaning that he had to work very very hard to become as skilled as he did (Harry and Hermione were both raised by caring parents who were also very intelligent and so they had an advantage in Hogwarts that Voldemort never did).
 * Problem with this theory is that Harry wasn't sorted into Ravenclaw; he was put in Slytherin and Dumbledore interfered (probably). Still, this would be an interesting development if true (I doubt it's true though, the hat's gotta be a bit smarter than that if it's worth the fabric it's made out of. Canon Riddle was already pretty Slytherin by the time Dumbledore found him).

Bellatrix Black is actually Narcissa Malfoy
As a corollary,the person burned to death in Narcissa's bedroom was the real Bellatrix.
 * Possibly the "new" Bella was made from Narcissa after Voldemort lost the original services.

Fawkes killed Narcissa(or whoever that was)
Phoenix=Fire.

The story is rock-solid hard SF
The story, rather than taking place in the recent past the way the canonical stories do, actually takes place several decades into the future. Like The Matrix, it takes place inside a computer simulation. Unlike The Matrix, the characters aren't flesh and blood humans plugged in to the computer simulation, they're all A Is. Different A Is in the story were deliberately designed with significantly different levels of sophistication and/or constraints on their behavior, which explains Harry's observations about PCs and NPCs and heroic supervision in chapter 75. The purpose of the simulation is an experiment to determine whether Harry is Friendly (i.e. whether he is safe to release from the simulation into the real world.)

H+C in ch 76 is Bellatrix
Evidence: he/she seems to be sure that Harry, once fully powerful, will crush Hermione. Inside knowledge of death-eaters - Snape and Lucius. High giggle. Though the encounter is not on the witch's staircase, she is obviously aware of the witch's staircase, which favors his/her witchiness - and I doubt that staircase would be a happy memory for Bellatrix. Bellatrix certainly has the power and ruthlessness for such an attack, which pretty much guarantees that Hermione will have at least some PTSD symptoms later. Motive is unclear, but if Bellatrix is loose and able to get into Hogwarts despite Dumbledore and the Marauder's Map, then Quirrel certainly has something to do with it.

Also, "recognition sent a jolt of terrified adrenaline bursting through her." Even Quirrel or Snape wouldn't trigger reflex terror before there was time to understand the implications. But Hermione has unquestionably seen pictures of Bellatrix, and who could be more terrifying?

Harry is going to end up screaming at Dumbledore and mugging Nicholas Flamel for the Stone when he finds out about it.
Rational!Harry isn't going to take NF keeping the Stone to himself lying down, and Dumbledore arguing that the Stone is a curse will only make him angrier. He'll probably find out about the Stone in Flamel's presence, attack DD and NF from behind, take the Stone, make tons of Elixir and magically pour it into the sea, possibly with Quirrel's help... then Quirrelmort regains full form, but can't kill anyone and rule Britain/the world until he destroys the Elixir, making Harry completely turn against Quirrel.

Wizards' lengthened lifespan is the result of diluted Elixir of Life
There's only one Philosopher's Stone (or at least very few), and they simply can't make enough Elixir of Life to make more than a few people actually immortal. However, they do have enough to make "everyone" (meaning Wizards) age more slowly, which they accomplish by putting what they do make into the water supply. This is probably the only way I can see Harry learning about the Philosopher's Stone (that it exists, and that someone is using it) and NOT immediately going into an Unstoppable Rage.
 * This theory actually makes a lot of sense--as I understand the stone only ever gave immortality of the "never aging or getting sick" kind, not the "stabbed through the chest" kind, and anyways the books canonically state that Flammel was still able to die when he chose to and I think state that he needs to constantly drink more of the potion to remain alive. So a diluted version making you age slower and get sick less certainly makes sense. And the "potions just redirect magic" thing plays into it well; making something like that would be hard, at the very least either requiring the sacrifice of something immortal or a scary number of non-immortal things (remember, it has already kept him going for a few centuries). And since we now know potions obey a conservation law, if the stone was designed to keep one or several people alive forever it can't keep everybody alive.

Greg Weisman is either a wizard or just knows about the wizarding world
Basically, the shout out to Gargoyles isn't just a shout out. Greg Weisman created the series based on the opera, since no one in the Muggle world had ever seen it (and the few that have can't really call him out on it, lest their local ministry "detain" them), and the wizard's don't know/don't care since the magic in the series doesn't work the same way as real magic does.

Harry's dark side and Quirrel's non-catatonic side are both part of something or things far older than Tom Riddle
This thing has something to do with Atlantis. For instance, it could be a human Atlantean who managed to self-improve their intelligence and was on the way to godhood when somehow they were thwarted (by the magic-causing AI? In a titanic struggle which resulted in deleting Atlantis from time?), and ever "since" has been trying to fully resurrect themselves and resume the path to godhood. Whatever-it-is is obviously not very human anymore; perhaps it never was, perhaps it was originally an AI, although that would make it harder to explain why immortality is such a struggle for it.

Voldemort was a failed attempt, perhaps thwarted by Riddle's irrationality (that is to say, Voldemort had a separate "dark side" like Harry's, but unlike Harry his human side also happened to extremely evil). Bacon's diary could be a horcrux of this whatever-it-is, and perhaps Bacon himself was a previous vehicle. (If only "by Francis Bacon's mysterious dark side!" scanned a little better, it would be a pretty awesome oath.)

The fundamental nature of prophecy might have to do with this entity's struggle with the force that thwarts it - since the force that thwarts it almost certainly has godlike power, including power over time, but is probably usually less than self-aware, somewhat like the hat.

One bit of evidence against this theory is that there were no such hints from the Sorting Hat, which by its own word would have been able to notice such things. But since the hat itself (unlike the author) has nothing to gain by honestly dropping such hints, that is not conclusive.

People are reading too much into the shout-outs
Yes, the author has in some cases been careful to explain his shout-outs – for instance, the somewhat-implausible reference to Harry having seen the Army of Darkness "preview", even though his parents had managed to keep the naughtier Tom Lehrer lyrics from him, and it's not as if he saw it on youtube when his parents weren't around. But there are other shout-outs to things which already existed at the time which aren't explained, and the answer is not some crazy theory, just the author having fun. For instance, "squeamish ossifrage" had already been encoded, but not decoded, at the time; yet I doubt Dumbledore had used legilimens on the relevant cryptographers. So this is not some massive crossover story, they're just shout-outs.

Two wizards can have a squib child because of quantum mechanics
This isn't so much a real WMG as post-hoc technobabble, but I leave it here in case any other readers (or perhaps even the author) want to embrace it. The idea is that the Source of Magic has to constantly check people's DNA to see if magical things should be happening around them. This extra "attention" is an observer in a quantum mechanical sense, and so affects the observed. That is to say, just as constantly shining x-rays on that DNA locus would tend to lead to it mutating into a nonmagical version, the same happens with whatever means the Source of Magic uses to check. Thus, magical genes mutating into nonmagical genes is a particularly common mutation. Since the Source of Magic (magically) goes straight to the correct locus, other genes are not affected. When this mutation happens in living wizards, it affects only certain cell lineages, so they retain their magic talent; but if by chance it affects their gametes, then their offspring can be squibs. However, once the gene is in a squib (including later-generation squibs who don't know any more than Muggles) it is no longer the subject of so much attention from the Source of Magic, so the extra mutations cease.

Of course, other squibs could simply be the result of illicit liaisons with Muggles. But if all squibs were such, then someone would have noticed.

If you want to stretch this idea a bit, you can explain the mystery of the (canon) frequency of half-blood wizards. Since recessive wizard genes are not common in the Muggle genepool, why aren't half-blood wizards vanishingly rare? Well, inside the mother, the Source of Magic still considers the fetus as part of the mother, and so it's checking for magical genes. The precise locus where the muggle allele differs from the magic allele is therefore subject to extra "magical radiation", and sometimes this leads to a reverse mutation, causing a cell lineage in the fetus which has two copies of the magic gene instead of just one. The baby, once born, then has mostly non-magic cells, but the few magic-lineage cells are enough for the Source of Magic to class him or her as a wizard. (In this theory, the Source of Magic decides magic-or-no on a binary basis, and relative magical strength comes from other factors.)

So if both parts of this theory were correct, you'd expect that

(halfblood wizards with wizardly mother)/(all halfbloods with wizardly mothers) = ((fullblood squibs) * (fudgeably age factor) / (all fullbloods)) + sqrt((mudblood wizards) / (all muggleborn))

, while

((halfblood wizards with muggle mother)/(all halfbloods with muggle mother)) = sqrt((mudblood wizards) / (all muggleborn)).

That is still a somewhat lower-than-canon fraction of halfblood wizards, but plausible. (And testable! Not that I expect Harry and Draco to actually try to test it, but ... let's just say I would if I were Harry. Too bad that fanfics don't have large "begat" sections, or I could attempt to test it myself from outside the fanfic. That is NOT a hint to the author; I'd have fun testing it, but it's not worth the WT Fs from other readers.)

Oh, another testable prediction: the chances of a squib child (legitimately) coming from two wizard parents would be about proportional to the total age of the two parents (or perhaps to the total number of spells they've cast, which should be approximately the same thing).
 * Simpler explanation: magic doesn't exist in genes at all. It's passed by heredity, but it finds its own way, independent of any long chains of mere matter.

Narcissa is only dead to Lucius some of the time. When he does to sleep at night, he's in another world where Draco died and Narcissa lives.
Actor Allusion.

Magic is actually sufficiently advanced technology
It's a supercomputer system with holographic/replicator capabilities a la Star Trek.

When it predicts the future during a Divination function call, it actually calculates all the particles that are currently within its system and all their interactions frame by frame (in other words, the universe is a deterministic system). However, it loses accuracy the further into the future it tries to calculate (perhaps due to the system being open---read: doesn't cover the whole universe---and thus susceptible to outside influences), and so it could predict a showdown between Harry and Voldemort but could not predict the final victor since it would be years before the actual outcome comes to pass.

On the other hand, as long as it's within a few hours, the predictions can be accurate enough to support the Time Turner. That's right, Divination is the basis of the Time Turner. How, you ask? Well, Magic isn't actually capable of manipulating time/changing the past: It simply predicts a future version of you that will use the Time Turner and then copies that version into the current time frame. And when the current version of you uses the Time Turner, the current version is simply erased from existence, leaving behind a future version that's so accurate in composition and behavior that nobody in the world can tell the difference. That's right, Harry has already cloned/killed himself hundreds---perhaps thousands---of times without even being aware of it.

By the way, since Harry couldn't prove P=NP using the Time Turner, that means:
 * Magic can't take too many recursions at once (hence why you shouldn't talk to your future self)
 * Magic runs in polynomial time
 * The future can be calculated in polynomial time
 * Magic has a sense of humor (rather than saying "Fatal Error: Out of Memory", it said, "DO NOT MESS WITH TIME")

Quirrel's plan is to frame Harry as Voldemort
Quirrel has made several public statements hinting that he thinks Harry should be/will be the next Dark Lord. Lucius Malfoy (may) believe Harry is Voldemort, and Bellatrix Black definitely believes that Harry is Voldemort, and Quirrel is literally tutoring Harry to become more like him.

Quirrel lied about why Voldie killed the dojo.
Quirrel is Voldemort, so why would he reveal his Fatal Flaw to everyone? He didn't--he created a fake flaw in order to (1) create yet another tenative Harry/Voldemort connection (see above), and if that plan doesn't work to (2) make sure everyone's misinformed about his weaknesses.

He probably did kill the dojo, however; as Quirrel says, you don't leave the source of your power lying around...

Salazar's Basilisk was behind everything.
Because Salazar Slytherin wasn't stupid enough not to have planned for the "heir of Slytherin" deciding to Avada Kadavra the basilisk once it's outlived its usefulness. Obviously, everything that's happened since Tom Riddle found the basilisk has been one giant Gambit Roulette. ;)

Professor Quirrell is actually Peter Pettigrew
Crazy, I know, but stay with me. In canon, Quirrell speaks with a stutter to make himself seem weak, right? He can speak normally, he just doesn't. This means that in order for that to be a valid plan, nobody at Hogwarts must have met Quirrell before he got seduced by Voldemort. This applies to Mo R as well. Nobody at Hogwarts knows who Quirrell is, he's a complete mystery. He could be anyone.

There are two ways the Pettigrew/Black debacle can be resolved in Mo Rverse: either Black is really guilty and Pettigrew is dead, which REALLY conflicts with canon, or Pettigrew is guilty and escaped like in canon, he's just not hiding with the Weasley family. It could go either way, but think about this: canon!Quirrell had Voldemort as a separate entity than himself, which isn't the case in Mo R. In Mo R, Voldemort and Quirrell are fused together. This means that Quirrell's completely accepted Voldemort's personality and fused it with his own. I can only think of two people who would be willing to do this: Bellatrix and Pettigrew.

If Pettigrew is guilty, he wouldn't be wasting time in hiding like in canon, he'd have found Voldemort by now. I'm pretty sure this is the case, there've been a lot of hints toward it. Voldemort needed a body, and Pettigrew would be readily available. Pay attention to the descriptions of Quirrell. A man in his late thirties, short and balding. That could EASILY be Pettigrew. Everybody thinks he's dead, and it's been 10 years since he was last seen, so most people aren't going to recognize him.

Lupin knows who he is of course, but he's protecting him because he believes Sirius was guilty, and if Pettigrew was found alive then it would cause too much trouble for his friend.

Snape also knows it's Pettigrew, they were Death Eaters together and Snape knows that Pettigrew is alive and working for Voldemort. Read the scene with them in the woods again, that scene confused me at first. Why would Snape have to pretend he's not working for Dumbledore for Quirrell? Because he believes that Snape's still working for Voldemort as a spy.

There're other hints as well. Quirrell tries to teach Harry humility, and the ability to 'lose'. Pettigrew's always been humble, and he 'lost' when he fought Sirius. In Azkaban, look at how Quirrell acts around Harry. He's acting like Pettigrew, the humble servant. It makes perfect sense that small, timid Pettigrew would learn martial arts, the story with the dojo was true.

Voldemort's synthesized himself with Pettigrew and learned humbleness and caution as a result. Pettigrew's animagus changed from a rat to a snake because of Voldemort's influence. It all fits, it explains the changes in Voldemort's behaviour as well as what happened to Pettigrew, and ties up those weird scenes with Snape and Lupin.

Nobody's ever heard of Quirrell because Quirrell doesn't exist, he's an invention of Voldemort and Pettigrew.

I'm not saying this is definitely true, but it would be a great twist, and the evidence seems to support it. It's exactly the kind of thing both Yudkowsky and Rowling would do.

Harry will generalize potions theory, rediscovering a lost form of magic
After deducing the theory behind all potions in chapter 78--that the ingredients store magical power which can be reforged into a desired outcome by ritualized spells--Harry applies the concept to other 'ingredients', such as the surrounding landscape.

The founders knew this theory and exploited the hell out of it when they created Hogwarts, its location in Scotland being no mere coincidence. Scotland is historically geologically active, and the millions of years of tectonic activity in that region would provide ample power for both the construction of the castle and the creation and maintenance of its many wards and enchantments.

The logical conclusion of all this--neatly packing away all the WMG for Harry's reaction to learning about the Philosopher's Stone--is that it is made of humans.

Alternatively, as the work-in-work-out potionmaking principle is about capturing the work through something which has been changed by the work, an ingredient would have to be altered by something else's immortality. For example, someone killed by an idea that just won't die.


 * It seems like if you're willing to accept the sacrifice of ideas as the source of the Philosopher's Stone, Merlin's Interdict is the logical thing that allows the Stone to be made. Perhaps in order to make enough for all humanity, Harry would have to extend the Interdict to Science.

Merope never stopped dosing Tom Riddle Sr.
(A consequence of the no Idiot Ball rule). Which means he didn't abandon her,and Voldemort wasn't raised in an orphanage...since by the time Merope died (even if it was still shortly after his birth),Senior wouldn't have been able to dump junior in an orphanage without wrecking his own social standing.

Harry is an escaped Atlantean.
That's what he's forgotten.The real Harry Potter, of course, was simply killed by Voldemort. There was a guess to this effect here, but it seems to have mysteriously vanished.

Harry will create a potion or ritual to give immortality by using a Dementor.
A potion reshapes the magic to create an effect. The Dementors are immortal. In a potion they could give the drinker immortality. If Harry can make more Dementors then he can give everyone immortality. With a ritual if you sacrifice Death, logically, you should be able to get immunity from Death.

Anyone Harry tells the truth about Dementors to will Obliviate themselves if they can't cast the True Patronus so he won't use it to threaten people.
This is the logical thing to do if that happens. The writer is not stupid and so by extension Harry is not stupid and will realize that this is a stupid idea. Plus they'd probably charge him with some crime and Quirrell at least would realize that that would happen.

The plan was never to kill Draco.
Harry assumes that the plan was to kill Draco and to make Lucius too burdened with rage and loss to think clearly, but things don't really add up that way. Assuming ourselves that Harry was correct and Voldermort was behind the plan, then it makes far more sense to have Draco be found badly injured/dying (and of course Draco was found by Quirrell). If Draco was dead there would be no one to actively accuse Hermione and for the plan to work at all she would have needed to become so burdened by guilt she turned herself in, something that there was no sign of happening before she was arrested. But with Draco still alive, his father finds out about how he'd been getting influenced by Harry, who will keep a closer eye on him and try to steer him towards being a proper Blood Purist/Death Eater once again to insure the blood purists have the financial backing of House Malfoy to rally around for another generation. Meanwhile Hermione would be shipped off to Azkaban which would so enrage Harry that he would be willing to tear down the obviously corrupt Wizard Society by becoming the next Dark Lord thus insuring Voldermort gains a powerful ally/enemy against Dumbledor/ someone to follow in his footsteps.
 * Given how Hermione acted afterwards, she was most definitely being burdened by that much guilt. The only thing that I could even imagine getting her past the 48 hour mark before she confessed would be the knowledge that she'd face a Kangaroo Court, and even that might not work. And anyways, with the death of the scion and only heir to such a Noble House they'd probably bring in a legilimens to help investigate, and she'd be radiating guilt like a beacon.
 * Agree with other commenter that the evidence given is faulty, even if the conclusion could well happen to be correct. Draco shows up dead; who are the suspects? Maybe that girl who was acting really angry at him the day before, and whom he had a good reason to challenge to a duel? Let's give her a drop of veritaserum and ask her the simplest possible yes/no question... or even just ask her without serum...

Mc Gonagall is Hermione's maternal relative (grandmother or grand-aunt).

 * This accounts for her repeated visits to Hermione before school started,rather than any attempt at intimidation(as Roberta thinks).

Harry's animagus form will be that of a phoenix but he will not get any of their abilities
The form of a phoenix would very much fit his personality, while not getting any of a phoenix's magical abilities would be an extremely interesting twist on a tired Harry Potter fanfic cliche. Harry would, of course, still find ways to use it to his advantage such as using tricks to make people think that he has a phoenix's abilities.

Harry will have two animagus forms
If one's animagus form is a reflection of your inner self, then it would make sense for Harry to have two forms, one for his normal self and one for his dark side. His dark side's animagus form would likely be a snake as a result.

Only Harry's dark side will be able to cast the Killing Curse
When Quirrel teaches the curse to students (he earned the right in his bet with Dumbledore about students casting the Patronus Charm), Harry's ideology, which allows him to destroy Dementors, will prevent him from casting the curse. Only Harry's dark side will be able to cast it, driving a wedge between Harry and his darkness. Light-side Harry will then develop a new version of the Killing Curse, possibly to heal or resurrect.

The Interdict Of Merlin is the point of divergence
In this world Merlin laid down his own life to create the Interdict. In the canon world, he didn't and used it to continue his work instead. As a result spells can be learned from books no matter how powerful they are, unethical use of spells is relatively rare, and magical nobility have lost all their legal privileges, even if they retain a lot of economic and political power.

Blaise is right, Quirrell isn't Hat & Cloak
Quirrell is smart, and someone else framed Hermoine, or has a bigger plan that's interfering with Quirrell's. It could be one of the good guys, like Dumbledore, but despite being insane, he's not likely to harm a student. Snape, perhaps?

Gilderoy Lockhart is a front for Alastor Moody.
Moody undoubtably prefers that Dark Wizards not know he exists at all, but he still needs some sort of contact person/face for dealing with people. Lockhart is that face(or one of them), playing the Inspector Gadget (high profile,high reputation distraction) to Moody's Penny (low profile,high effectiveness).

Gilderoy Lockhart is famous for his skill with memory charms.
Lockhart runs a professional memory modification business, obliviating people like Mr. Bester or removing painful memories for people who can't bear them. Under the table, he handle some shady jobs, like memory charming Rita Skeeter. However, his job also gives him access to a lot of secret/private information, so he also acts as information broker.

Nobody knows TMR's middle name
This is just a simple consequence of the no-idiot-ball rule.

The Hero who QQ is suspected of being is not TMR
TMR is the obvious suspect, but the birthdays don't match, nor does the grandmother. So, there was a Most Ancient scion who was a classmate to TMR. Possibilities then include: If this is true, then Harry's dark side is probably still Voldemort.
 * 1) Hero and TMR/Voldemort were in cahoots, playing both sides of a con
 * 2) TMR/Voldemort took over hero when he was in Albania and either puppeted or polyjuiced him from there on.
 * 3) Hero was actually fighting TMR/Voldemort, but then got fed up and took over the Voldemort role (by killing Voldemort).

Quirrel's catatonic rest is not just a symptom of being dead, but is when his soul is running some other body
There's almost no question that the author would allow a single intelligence to split into two clones, but it's plausible that he wouldn't allow them to re-merge after that. Quirrel has lots of plots, so he goes and does those other things while catatonic. The supposed "increased frequency" is because he's has to deal with Bellatrix somehow. Note that the prohibition on re-merging intelligences would mean that his ultimate plot with Harry could not be to re-merge with Harry's dark side.

Roger Bacon damaged the Source of Magic.
No one was as good as Merlin, and supposedly afterward no one was as good as the Founders-but all 5 of those wizards are British, and that trivia comes from a British wizard,so should be regarded with skepticism. There may well have been other notable powerful (comparable to the founders) foreign wizards in between. This is the reason this story's Hogwarts founders are from the late 12th/early 13th century-to move the date of the founding to just before Bacon broke magic.

Harry is the next Dark Lord. Draco is the one in the prophesy.
Harry is teaching Draco his methods, thus marking him as his equal. Draco is gradually treating people better and thinking for himself, while Harry does Dark Things and ignores warnings about turning into a Dark Lord.

Voldemort never died. Not even a little bit.
A charred body was found next to baby Harry, and suddenly Voldemort wasn't doing stuff anymore. Everyone assumes this is because Voldemort is dead, but he may simply have faked his death and gone into hiding. Voldemort seemed to be winning the war, but the prophesy was out there, and the Order of the Phoenix was getting closer to being able to attack him directly, not to mention having spies like Snape in the Death Eaters. Voldemort's number one priority is not to die, regardless of his other plans. He attacked Godric's Hollow in order to make Harry into a Horcrux (which he did deliberately) and make it look like he had died, to take the heat off him. "Quirinus Quirrell" is simply Tom Riddle, as Amelia Bones suspects.
 * 1) It IS known, that Tom Riddle=Voldemort in this universe, Dumbledore mentions him as such. Amelia directly mentions that her-guess-on-Quirrel was Voldemort's enemy. Which means that her-guess-on-Quirrel is NOT Tom Riddle. In addition, author commented in discussion thread that this hypothesis is false and specifically changed QQ's birthyear to not match with Riddle's.

Time-Turners ARE Turing computable
As "Two wizards can have a squib child because of quantum mechanics" this is more like theory about how world in Mo R runs, but I beleive it belongs to here.

In chapter 14 Harry says that magic could be explained if the Universe is a computer model, but for not being Turing computable, Time-Turners are breaking even this theory. But under certain conditions they actually are computable. Fisrt, let's define a Very Simple Time-Turner Problem: If we know that h2 is actually h1 came from t2, we can write equitation: h2(t1) = h1(t2) - Time-Turner-Bit. Now we can pause main world simulation and perform some brute-force search in a sandbox (as long as our memory is infinite, we have a place to do it). We will just iterate over all possible states of Harry's memory (let's call them h2n), assign h2(t1) = h2n and then propagate all steps to moment t2 and then check if their interaction results in h1(t2) = h2n + Time-Turner-Bit. Now we can assign h2(t1) to the first found suitable h2n, and it will result in stable time loop. Case solved! If we can't find suitable h2n, then our presumption of h2 coming from the t2 to t1 is just wrong, there's no any time loop which cat lead us to it. This also explains why every single time traveler fulfills time loop instead of checking what happens if he doesn't (assume he has a suicidal and apocalyptic intent): if he hasn't a strong intent to fulfill it, he just couldn't come up with idea of time traveling, according to the mechanics of the Universe. Of course, we can speed up these calculations by assuming that the entire state of h1 could not be changed so dramatically from t1 to t2. So we can start brute-forcing not from memory state 000...000 and to 111...111, but start with assuming h2(t1) = h1(t1) and then iterating over states with increasing Levenshtein distance. But nonetheless, it's brute-force problem.
 * Entire Universe is simulated in the computer's memory.
 * Memory is potentially infinite, but discrete.
 * World is fully determinictic, computation from given state of memory always results in same steps.
 * To simplify reasoning let's assume that the basis of simulation isn't particles, wave functions or something, but actors representing humans and objects from environment. It's an object in memory which has it's internal memory, representing all data about it's current state (memories in his brain, position in the space, current heart rate and so on), which is transformed on each step by simulating computer according to universal rules. One of possible transformation is interaction between actors.
 * Amount of one actor's memory is finite and known to simulator (such is real life: at least your memory can't be larger than required for memorizing positions of all particles in your body).
 * A certain actor, let's call him Harry, can travel in time using Time-Turner.
 * Travel is instant, we can imagine that there's a certain bit in Harry's memory which is checked by simulator on each step, and when it appears to be "1", in the next step Harry will be in past with Time-Turner-Bit switched to "0".
 * For some reason we just know that on certain moment t1 Harry will come from moment t2 in future. So, on t1 we'll have two copies of Harry: original h1 and came from future h2.
 * State of h1 is known because defined by previous steps of simulation. And we know that in the moment t2 actor h1 will have "1" in Time-Turner-Bit.
 * We don't know contents of h2 (Harry which came form future), we must calculate it so the Universe will be consistent. How?

Now let's try to bound this solution the real Mo R world. Both this solution and sentence about your inability of changing time in Mo R explicitly stay that there's no any randomness, at least in the past light cone from point h1(t2) to the moment t1 (let's call it L1). What should we do with true quantum randomness? We can simulate it. For our space-time in simulation is discrete and L1 is finite, there's only finite amount of random events and their possible outcomes which could be theoretically observed by both h1 and h2 within time from t1 to t2 under any conditions. So we can just write up all required random outcomes in a certain vector r1 and then calculate plausible values of r1 and h2 together, the same way. Which obviously will slow down computations, but at last we need to cancel randomness not to the entire Universe, only to space-time lying in L1.

But the real problem is defining t1 and t2. Well, almost t1, because as it is defined, we can just propagate steps forward and check, if we will come up with h2(t1) = h1(t2) for t2 = t1 + {1h, 2h, 3h, 4h, 5h, 6h}. I see no way to define it but assuming on every single step that h2 will come here, and only if all calculations mentioned above won't result in stable time loop, we would think that there's no time travelers arriving to this particular moment. But not sure about about this moment + 5.4e-44 seconds, so we must perform this test for it too. Um. Well. Well, it is still computable. It's unimaginable difficult to compute, incomparably harder than factorizing a factorial of the Ackermann function, but it is computable. I can think about certain optimizations such as if person doesn't have Time-Turner, using light cones we can check if he can get one in next 6 hours (so, do we need to perform all brute-forcing for him or not), or if a person with Time-Turner didn't use it, we can estimate how long does it take to the Universe to be changed enough to result in other solution through some stochastic processes.

The only thing that still unclear is a concept "you can't change things about which you knew in the first place". The Universe doesn't run on concept of awareness, it runs on causality. Anything lying in the past light cone of a certain event is it's cause. I may not be aware of what reader of this text did 21 milliseconds earlier than I wrote it, but elementary particles in my brain certainly are. Even if you're sitting in Cheyenne Mountain bunker, neutrinos and gravity fields still can connect us. The only solution I see is that this constraint is only visible consequence of the fundamental fact of impossibility of changing of entire time line. Wizards think that they being sent to past they still acting by their own will, while actually their actions and thoughts were entirely predefined.

Popular things in Muggle culture is remade for Wizards
Like The Tragedy of Light, which is actually Death Note. People are capable of getting away with blatant plagiarism because: 1) Most wizards don't know anything about the Muggle world and truly believe that it was created for wizards, 2) Muggle wizards get to watch the real deal, so they don't really care, and 3) Who would beleive that you're being plagiarized by wizards?

There will be a version of Dumbledore's Army in MOR-verse
But it will be led by Dumbledore, Harry and/or Mc Gonagall after Quirrell leaves. And Harry, Hermione and Draco will become a Power Trio of some sort and utterly steamroll Voldemort, which is why Quirrell wanted to turn them against each other.

Taboo Tradeoffs is Xanatos Gambit that went exactly as according to plan
It is obviously a plot by Voldemort to weaken Harry by splitting up his band of trusty companions. The one-level play is that the goal was to kill Draco and frame Hermione. This would deprive Harry of Draco, neutralize Hermione, and make Lucius wreck his own game for vengeance. The two-level play is that Quirrell saves Draco. This does the same except instead of killing Draco, Draco is whisked to safety by Lucius. However, Harry gives up his fortune and swears Hermione to his service to save her from Lucius. The three-level play is that Draco is still removed from the picture, Hermione's reputation is still dirt, Harry has no warchest, and Hermione is sworn to Harry in a light mirror to how Bellatrix served Voldemort. Quirrelmort totally won this one.

Harry will sacrifice himself and use his love for Mankind as fuel to cast a MASSIVE version of the Sacrificial Protection spell for EVERYONE ON EARTH, saving EVERYONE from death
Or at least Sacrifice his dark side, the Horcrux. And I don't doubt that he would be able to find a way to do so. The crux (hee hee) is that Harry will have to willfully accept death, but that doesn't seem TOO out there as a plot point. Or, if he actually dies, he can just undergo cryonics. It's not like that was never NOT an option. Hell, you have to be legally dead to undergo it now, right?

If Dumbledore knew about the Pioneer Plate, he would just use the Elder Wand to summon it towards him
Because the Elder Wand has monumental power, and Quirrelmort's power is as far away from it as a Googolplex is from infinity. Well... ish. ALSO, the only specific requirement for the Summoning Charm is that you have to have the object clearly in your mind, and that range doesn't matter. Harry could just... show him a picture, right? He has BOOKS. HOWEVER, there are spells that prevent summoning. But then AGAIN, it's the friggin' Elder Wand.

Whoever manipulated Hermione into trying to kill Draco wanted to make a Horcrux
Dumbledore: "There is a murder, committed in coldest blood". Hermione hit Draco with a Blood-Chilling Charm. Significant?
