Fringe



"We create technology. How it is used is not our concern."

- Nina Sharp

"There really isn't a point where things just can't get weirder, is there?"

- Olivia Dunham

Fringe is a sci-fi TV series created by J.J. Abrams and ongoing J.J. compatriots Alex Kurtzman and Roberto Orci. Other J.J. coworkers from Lost and Alias are involved as well. In concept, it's like The X-Files, with the primary threat being Mad Scientist terrorists instead of an Alien Invasion. In practice it is like The X-Files meets CSI.

Like J.J.'s other shows, it has a slowly developing Myth Arc involving an Alternate Universe, an Action Girl, and also has some crazy, off-the-wall happenings right from the get-go. It's quite a Mind Screw. The show premiered in August 2008 on FOX.

Has a Recap page.

WARNING: This page contains a large number of unmarked spoilers. Tropers new to Fringe proceed at your own risk.

Tropes A-E
"Astrid: I went to Quantico for this?"
 * Aborted Arc:
 * Agent Amy Jessup was brought in during the Season 2 opening and looked to be bringing in some religious interpretations to the Fringe cases. She appeared in two episodes then was dropped without a word of explanation.
 * Above Good and Evil: In the episode Amber 31422, the other Walter Bishop, the inventor of the titular substance, says to Broyles: "Nature doesn't recognize good and evil, Philip. Nature only recognizes balance and imbalance. I intend to restore balance to our world. Whatever it takes."
 * Absurdly Spacious Sewer: In "Unleashed".
 * Action Girl: Olivia Dunham. "Bound" will dispel any doubts on this count.
 * Altlivia definitely qualifies.
 * Acting for Two: All of the characters who have doubles on the other side.
 * Actor Allusion:
 * Peter mentions the remake of Invasion of the Body Snatchers to Olivia. This version starred Leonard Nimoy, who plays William Bell.
 * Walter's research on LSD-induced hallucinations that can grant the subject clairvoyance is similar to the plot of the book (and later film) Altered States. The film version starred Blair Brown, who plays Nina Sharp.
 * Among William Bell's books in the episode "Concentrate and Ask Again" is a copy of a book by Dr. Spock. Another Leonard Nimoy reference.
 * Peter and Olivia meet with a conspiracy theorist who believes himself to be Spock from Star Trek. You should already know who played Spock. More of a Director Allusion, but the story that he tells is somewhat similar to the plot line of Star Trek. However, this was probably intentional as the episode aired in the opening week of the film, and therefore was used to promote it in the process.
 * The episode "Stowaway" involves a woman named Grey who is suicidal after losing her family. The climax of the episode involves a train bombing. Who was she played by? Amanda Greystone.
 * The Season 4 finale featured another character played by Rebecca Mader who near death starting talking like a child. Albeit this time Mader's character's mind reverted to a child's after death, not prior to it.
 * A Day At the Bizarro: Season 2 episode 20, "Brown Betty". Season 3 episode 19, "Lysergic Acid Diethylamide". No, it's not a coincidence that both are named after (and involve use of) mind-altering drugs.
 * Ad Bumpers: Before each commercial break, there is a brief clip of an image (a frog, flower, etc...) accompanied by a speck of light. About halfway through the first season, devoted watchers figured out that the images were part of a substitution cypher and cracked it.
 * A Death in the Limelight:
 * All Germans Are Nazis: "The Bishop Revival" featured a very stereotypical German (round glasses, hairstyle, clothing, accent) who is revealed to be an original Nazi. And guess what he was doing! Trying to create a virus for eugenics, of course! The same episode reveals Walter and Peter's German background, which has to be something of an aversion in that while their ancestor was a Nazi scientist, he actually worked as an Allied spy, subverting the war effort behind the lines.
 * All the Myriad Ways: Averted. People from the alternate universe aren't treated as less important than those from our universe, leading to major dilemmas when all the characters believe that only one of the two universes can survive. It's finally revealed that the reason the universes can be crossed at all is because they are linked - the destruction of one would cause the other to follow. Peter links the universes together in a way that stabilizes them, and the characters from either side need to learn to work together and trust each other.
 * All Theories Are True: The entire premise of the show.
 * Almost Kiss:
 * Alone with the Psycho: Olivia ends up alone with the guy with the cancerous touch.
 * Alternate Universe: a huge part of the show's central mythology.
 * And if you thought that was bad, now we have an established Alternate History since the start of Season 4. In both universes.
 * Alternate Universe Reed Richards Is Awesome: Walternate.
 * Always Close: In "Enemy of My Enemy", 4x09,
 * Amazingly Embarrassing Father: Peter visibly cringes whenever his father makes an embarrassing non-sequitur.
 * Ambiguously Human: The Observers, at first. It's eventually revealed that.
 * Anachronism Stew: In "Brown Betty", Walter tells Olivia's niece a story in the style of Film Noir - with clothes, hairstyles and interior based on the 1940s - oh, and computers, mobile phones and quantum lasers. In his defence, Walter was hopped up on drugs at the time. Not to mention the fact that he's completely crazy anyway. It was just a fairy tale story for Olivia's niece, so it's probably a good thing to really just relax.
 * And I Must Scream: Happens a lot.
 * Peter's flyover of the Alternate New York includes the tidbit that people in the Madison Square Garden quarantine zone have just recently been declared legally dead.
 * In "Amber 31422",
 * They guy from 1x02 uses a muscle paralyser to prevent his victims from moving while he removes their pituitary glands.
 * Olivia in "Entrada".  While she was awake and completely conscious. They even drew guidelines so she knew exactly what they were going to do.
 * Milo Stanfield in "The Plateau" becomes
 * And There Was Much Rejoicing:
 * Animal Wrongs Group: In "Unleashed", these guys let the monster-of-the-week out. They chose poorly.
 * Anti-Hero: The more we find out about Walter Bishop's past, the more it seems like putting him in the asylum was the right choice.
 * Anti-Villain:
 * Doctor Nayak. An addict with a Jekyll and Hyde split personality, he wasn't even fully conscious of what he was doing, and his almost constant look of horror as he becomes aware of what his darker half has been doing is truly heartbreaking.
 * Alistair Peck, a man who was willing to go to any lengths to perfect time travel to save his fiance from her tragic death.
 * Alan Ruck plays a scientist who stumbles across a possible cure for his paraplegic son, and becomes so desperate to perfect it that he kills several other crippled people that he used for test subjects.
 * Dana Gray. A woman who watched her family murdered before her eyes and normally would've been killed herself but because of bizarre events ended up in a state where she could not die and was merely seeking a way to end that.
 * Eugene from Wallflower.
 * Apocalypse How: Class X.
 * Applied Phlebotinum: What do people who've taken Coretexiphan do? What don't they do? Cortexiphan has been described as making those taking it better able to tap into their inner powers, which, being that every human is unique, is different for every person.
 * Arbitrary Skepticism: Peter frequently lampshades whatever weirdness is going on in the current episode. (He's stopped being actively skeptical, and now just points the weirdness out.) There was also 2x11, "Unearthed", which may qualify as an inversion or something; it had a scene where Walter argues with a priest over whether exorcisms are real or superstition. The man of science and the man of faith are on precisely the opposite sides you'd expect.
 * Arc Numbers: Like other shows by J.J. Abrams, there are numbers that often reoccur:
 * Examples of the number 47 appearing are:
 * In "Pilot" (1x1), there are 147 passengers on Flight 627.
 * In "In Which We Meet Mr. Jones" (1x7), Loeb mentions something on page 47 of the document he’s looking at.
 * In "Safe" (1x10), the flight with the veterans on it is said to have landed 47 minutes ago.
 * In "The Transformation" (1x13), there are 147 passengers on Flight 718.
 * In "Ability" (1x14), the bomb is located on the 47th floor of the building. The bomb also consists of 47 lights.
 * In "Inner Child" (1x15), the clue the child writes for Olivia is “547 Marlborough.”
 * In "Fracture" (2x3), Walter says that he “stopped counting at 47 needle-marks” when asked how many were present on a corpse.
 * In "Momentum Deferred" (2x4), it is revealed that the shapeshifters’ blood is 47% mercury.
 * In "Johari Window" (2x12), 47 people were born in Edina between 1990 and 2000.
 * In "Jacksonville" (2x15), Broyles says that the list of buildings that might disappear has been narrowed down to 147.
 * In "Brown Betty" (2x20), Peter says that there are 147 pins in the map in his kitchen. Another one is that Nina Sharp's private parking space is No. 47.
 * In "Over There, Part 2" (2x23), the Alternate Universe Fringe team locates Olivia when her “Show Me” passes an auto-checkpoint in Sector 47.
 * In "6:02 EST" (3x20), the electromagnetic spike occurs at 5:47 A.M.
 * In "The Day We Died" (3x22), the Bad Future takes place when Peter is 47 years old.
 * In "Novation" (4x5), the shapeshifter gets the typewriter that communicates with the Other Side out of a storage locker marked 47.
 * In "And Those We've Left Behind" (4x6), the time chamber Raymond Green created can't last for more than 47 minutes each time.
 * In "Enemy of My Enemy" (4x9),  says that he has made 47 shapeshifters so far.
 * In "Making Angels" (4x11), the suspect of the week carries TSA badge 0047.
 * The number seven itself appears to have some great importance:
 * Walter was institutionalized for seventeen years.
 * Peter.
 * Peter has been arrested seven times.
 * Peter and Olivia
 * There were thirty-seven children in the Cortexiphan trials.
 * Arc Words:
 * "The Pattern"
 * "The First People"
 * Ascended Meme: In "What Lies Below," a computer model shows a projection of the virus's spread around the world. The entire world turns red except, curiously, Madagascar.
 * Even the captions refer to alternate Olivia as her Fan Nickname "Bolivia".
 * Ascetic Aesthetic: Massive Dynamic is in love with this style. Some quick Google-fu seems to have confirmed this Troper's eyes' suspicion that Massive Dynamic is housed in Toronto's Royal Ontario Museum.
 * Asshole Victim: The two kids who  at the beginning of "Alone In the World" are bullies who were planning on beating up the Woobie. A somewhat disturbing example since little to no sympathy is extended to them by any of the cast members, despite the fact that they're still just 12 year olds.
 * Autopsy Snack Time: Walter often eats while examining corpses or other Squick-inducing things.
 * Awesome By Analysis: Used by the Villain of the Week in "The Plateau" to cause Disaster Dominoes to kill people.
 * Back for the Dead:
 * Backup Twin: A sort of in-universe example
 * Badass Bookworm: Peter Bishop.
 * Badass Bystander: The one security guard who takes on a shapeshifter in Momentum Deferred, after getting shot in the gut.
 * Badass Damsel: Kidnap either of the Olivia Dunhams and suffer for it.
 * Badass Grandpa:
 * Unseen, but Peter's grandfather was a spy for the Allies during WWII.
 * Also William Bell, as about a dozen Alternate Fringe Division agents found out to their misfortune.
 * Badass Longcoat: Peter, again. Not to forget Olivia.
 * Bad Future:
 * And, judging from the leaked intro,.
 * Bald Black Leader Guy: Philip Broyles.
 * Bed Trick:  Well, sort of.
 * Becoming the Mask: "Do Shapeshifters Dream Of Electric Sheep" reveals that this can happen to shapeshifters.
 * Beleaguered Assistant: Poor Astrid, at least at first.

"Olivia: Don't placate me because you think that I'm- Henry: What? Crazy? And what would you think if I jacked your cab in a hospital gown with a gun, screaming a conspiracy, telling you I'm being chased by the government and folks are trying to make me believe I'm a tattooed version of myself?"
 * Berserk Button: Walter gets very angry when Peter's life is put in jeopardy
 * Holding a knife to Peter Bishop in an attempt to  works spectacularly.
 * Bittersweet Ending:
 * In "Welcome to Westfield" (4x12)..
 * "Letters of Transit."  It's not much, but it's something.
 * "Worlds Apart."
 * Black Bra and Panties: Agent Olivia Dunham, God bless 'er.
 * And Fauxlivia wears white underwear. I'm pretty sure the show has been consistent with this.
 * The Blank:
 * Turns lethal when a string of victims' facial features start rapidly growing over, causing death by suffocation. Even a tracheotomy can't save them, as the growing tissue quickly seals any such air holes as fast as they are made.
 * A relatively tamer version appears in a hallucination in "Dream Logic" (2x05).
 * Blessed with Suck / Cursed with Awesome:
 * Joseph Meagar in episode 5 is able to generate powerful electric fields - but not to control them, which leads to him accidentally killing his boss and shorting out his mother's pacemaker.
 * Another character is able to predict deaths - leaving his head full of almost ceaseless nightmarish visions.
 * A girl named Emily has the same ability.
 * The Cortexiphan subjects. All of them.
 * Nick Lane is a reverse empath. His feelings are projected to those around him. He has absolutely no control over this ability, and since he's suicidally depressed and extremely alienated from society, the results aren't pretty.
 * The guy from "Concentrate and Ask Again" who cannot stop himself from reading other peoples minds and gets terrible headaches when he does. He's basically a hermit.
 * The guy who got nervous on a date and ended creating a magnetic field that ripped the filling out of his date's teeth.
 * Blue and Orange Morality: The Observers. The best understanding of their motives is that they strive towards "balance," but aside from that they are fairly inscrutable. The episode "The Firefly" shows their interesting morals:  And Walter thinks all of this was to  . However, the real reason for the Observer's actions:
 * Body Horror:
 * You know how guys cross their legs in sympathy after watching someone take it to the nads? That's what is like for women.
 * "Ability" (1x14) revolves around a chemical that seals your orifices shut.
 * In fact, the entire show thrives on Body Horror. Virtually all the Bodies Of The Week have to do with being killed, incapacitated, etc. in weird and squicky ways.
 * The pilot leaves no doubts about it, when he see a man's jaw melt off, followed by an agent being infected with a disease that renders his skin transparent.
 * Alistair Peck...ewww.
 * "Jacksonville", anyone? Even Astrid couldn't take it.
 * "Marionette" had double doses -- the first from the people having their organs removed, the second from the puppet body.
 * Body Snatcher:  ought to count even if it's instigated by him, not sure which of the subtropes fit best though. We'll just have to wait and see...
 * Bollywood Nerd: Dr Nayak.
 * Bread, Eggs, Milk, Squick: In "Brown Betty" 2x20 Story-world Walter is responsible for inventing: Hugs, Bubble Gum, Rainbows, Flannel Pajamas and... Singing Corpses
 * Break the Cutie:
 * Episode five's Joseph Meagar. He starts off the typical, moderately repressed guy living with his nagging mother, working in a job he dislikes and has a mostly harmless little crush on a girl who won't give him the time of day. Cue the electrical superpowers and his new Walking Techbane status. He inadvertently kills half a dozen people (the girl he likes included) with an elevator, gets fired for being late (you know, right after the elevator incident), possibly kills his boss by getting a machine to malfunction and mutilate his arm, then comes home to tell his abrasive mother what happened... only to short circuit her pacemaker. All on accident. And that's before the bad guys kidnap him.
 * The entirety of the series seems to be devoted to breaking Olivia Dunham. She gets through a godawful childhood (involving  a monstrous stepfather, and what sounds like a Promotion to Parent). She manages to find a job that she enjoys and falls in love with her partner. Partner is injured. She goes to incredible lengths to save said partner. She finds out that   In the first episode. Turns out   so no happy ending. She falls in love with   She spends the beginning of "Marionette" with the most adorable smile on her face. When she sees Peter, she does the whole shy teenager glance thing and just seems so happy to back. And then she finds about   The smile is gone. She's been   how many times? Plus she   And then there are the   Oh... and her friend ended up   It's like watching someone dangle a bone in front of a puppy and then kick it for good measure.
 * Break the Haughty:
 * Over time, you realize this is what St. Claire's did to Walter.  Given what Walternate is like, this can only be a good thing.
 * Peter in the first episode... a bit of a Jerkass. Peter in Season 4... dear God, someone give the man a hug.
 * Fauxlivia. Smug, bitchy alternate in first appearance. In "The Consultant"?
 * Breather Episode: Brown Betty.
 * Brief Accent Imitation: Pretty much the entire cast in "Brown Betty" puts on a noir-ish New York accent to keep with the theme of the episode. Most of them are hilarious.
 * Brown Note:
 * In Season 3's "The Box", a sound coming from a box somehow turns people catatonic, and even blows up their heads if they had something like dental ceramic crowns on teeth. Temporary or permanent deafness makes a person immune to the effect. The Suspension of Disbelief called for here may call for an unusual level of willingness.
 * "6995 kHz" in turn has an amnesia-inducing signal piggybacked onto a numbers station's broadcast.
 * Bullet Catch:  can do this pretty much whenever the hell they want to.
 * California Doubling:
 * New York variant, while some of the establishing shots are filmed in Boston, the rest of it is filmed around New York City. Note how all the license plates that don't belong to characters are New York ones not Massachusetts.
 * Soon to become Boston Doubling, as production has moved to Vancouver for Season 2.
 * Call Back: In the first episode, Walter laments the quality of the butterscotch pudding at the institution. When he returns to speak with a friend there, the friend is eating said pudding.
 * Came Back Wrong: In "Marionette" the Villain of the Week cryptically says
 * Chameleon Camouflage: Eugene Bryant in the episode "Wallflower" has this ability, since he's been genetically modified to shift his pigment around like an octopus.
 * Character Development:
 * At the start of the series, Peter is a nomadic, selfish, sarcastic Con Man and something of a Jerkass. After  making peace with Walter and hefty amounts of everything going to hell, he's willing to risk his own life to save the people he loves and the two universes.
 * Walter was a brilliant but arrogant scientist with no regard for ethics whatsoever. . By season four, he flatly refuses to play God again and he's willing to   if it means saving the lives of billions of people.
 * Chekhov's Gun: It's very common to see an item mentioned/shown in passing in one episode only for it to be used as a central plot device just a few episodes later.
 * "Over There part 1" demonstrates how vortexes are closed on the B-Side: a gas that generates into a rock-solid amber-like substance - the very same substance which appeared in the series' third episode ("The Ghost Network").
 * "Over There Part 2" has a near-textbook example. In the beginning of the episode,.
 * Subverted with the tracking device Walter implants in himself at the end of "Snakehead". Frequently referred to. Never used. Instead, first time Walter is kidnapped, they find that the kidnappers removed the chip first.
 * The bell that William Bell leaves Nina  turns out to be the activator for.
 * Walter's  in the Season Four finale.
 * Chekhov's Gunman: Sam Weiss is introduced in early Season 2 as a sort of Trickster Mentor for Olivia (at least, as far as physical recovery goes). In Season 3, we discover that
 * Chekhov MIA: William Bell.
 * Chekhov's Skill:
 * Chemistry Can Do Anything
 * The Chessmaster: Milo Stanfield in "The Plateau," Up to Eleven. He can perfectly calculate his
 * CIA Evil, FBI Good
 * Cloudcuckoolander: Walter Bishop. Those 17 years at the asylum have not been good for his sanity. Especially as he is a dyed-in-the-wool Mad Scientist with a tendency to actually say They Called Me Mad. Shrinks really take stuff like that personally.
 * In one episode, Walter's thought process is shown to be so baffling that it causes a mind reader to pass out. It's later revealed that
 * The Cuckoolander Was Right: More often than not, Walter is right.
 * Coca Pepsi Inc: The alternate universe has Shexxon, presumably the result of a merger between Shell and Exxon.
 * Colour-Coded for Your Convenience: The opening credits often change colors from the traditional blue to red, grey, and/or amber, depending on the episode - see Special Edition Title below.
 * Olivia wears black underwear and Fauxlivia wears white underwear (oddly subverting both Light Is Good and Dark Is Evil).
 * Although this is less clearly a subversion as you get to know Fauxlivia.
 * Combat Pragmatist: Olivia.
 * Con Man: Peter.
 * Conspiracy Theorist: Lovingly subverted with Olivia in "Olivia." Dressed in a hospital gown, she jumps into a cab and rants and raves to the driver about secret government conspiracies, doubles, kidnappings, and 'experiments'. We of course know it's all true - but think about it from Henry's perspective:
 * Conspiracy Theorist: Lovingly subverted with Olivia in "Olivia." Dressed in a hospital gown, she jumps into a cab and rants and raves to the driver about secret government conspiracies, doubles, kidnappings, and 'experiments'. We of course know it's all true - but think about it from Henry's perspective:


 * Contamination Situation: "What Lies Below"
 * Contemplative Boss: Walternate in his office.
 * Continuity Nod: Tons and tons. The show keeps excellent track of its internal continuity.
 * Walter mentions in a few episodes that one of his favorite bands is the nonexistent "Violet Sedan Chair." In the episode "Firefly," we meet Walter's musical idol - the keyboardist from Violet Sedan Chair.
 * In the first season, it's mentioned that kids treated with Cortexiphan tended to try and blend in, and wore monochrome colors. In the fourth season, Olivia tracks down a Cortexiphan test subject, and we get a shot of his wardrobe, filled with black, white, and grey outfits.
 * In the season 2 finale, we see Fringe agent Lincoln Lee checking for dimensional instability with a combination spray and handlight. In the fourth season, Astrid uses the same device for the same purpose, with Walter in the background bitching about how
 * Cool Big Sis: Olivia, to Rachel. Though it's Rachel who's the one to fuss over and worry about her sister (for increasingly good reason).
 * Cosmic Retcon: The Season 4 premiere shows that much of the show's history has changed as a result of Peter's retroactive disappearance. Walter has refused to leave the lab since Olivia sprung him from St Claire's, and Lincoln Lee doesn't remember meeting the team in "Passenger". It was also implied that the John Scott arc of season 1 didn't happen, and that the nature of Walter and Walternate's conflict is very different.
 * Crapsack World: The alternate universe is a strange case: It is much more advanced technologically and medically (they had modern cell phones in the mid-80s). The society itself is also implied to be slightly better-off, or at least less destitute financially. On the flip side, Fringe events have destroyed numerous cities. New York itself is covered with blotches of quarantine zones. In some parts the air is actually dangerous to breathe. There are numerous epidemics in progress, some of which involve diseases that exist in our universe but hit theirs much harder and others that don't even exist in ours. Real coffee is hard to find. Wallabies and sheep are extinct alongside numerous other species. And the government is implied to be more authoritarian even without the involvement of . And there are no rainbows.
 * Becomes a World Half Full when the bridge begins to heal the damage done and lost areas start getting reclaimed.
 * Creepy Child: The child in "Inner Child."
 * Crazy Consumption
 * Crazy Consumption

"Walter: Well, tell her what I said. Ask her why she destroyed files. Go on, ask her!
 * Curse Cut Short

Nina: Maybe you can ask Walter if he remembers what group the boy was in. I mean, that may help.

Astrid: Of course. Walter, did you hear that?

Walter: Yes. Her voice goes right into my inner ear and rattled around like razor blades. Of course I heard it. Tell her to go-

Astrid: He said that he is not sure, but thank you for the suggestion.

Walter: I did not say that!"

"Peter: Yeah, 'cause bootlegging smack in the basement is the picture of normalcy."
 * Cyberpunk: The series itself is not an example (barring the idea of technology run amok). However, Charlie Francis' monologue near the end of the first episode touches a lot of the themes of Cyberpunk.
 * Most of what happens in our universe is more correctly Biopunk than Cyberpunk, although they are closely related. Its more to do with doing weird crap to people and DNA and what not, rather than the more computer/machine focused themes of Cyberpunk.
 * The alternative universe is genuinely very cyberpunk.
 * The setting and mood of  is very Cyberpunk, even if it doesn't follow the usual Cyberpunk tropes.
 * Cyberpunk Is Techno: Not techno per-se but the music in the  has an Industrial and Electronic Body Music vibe to it.
 * Damsel in Distress:
 * In most episodes, Peter is either filling this or doing something Badass. Sometimes both. This is subverted in the episode where Olivia finds herself trapped in her apartment with a killer and phones Peter for help...
 * Olivia does need rescuing a few times but it never diminishes her Badass, Action Girl status. In 2x01 she (understandably) spent the entire episode completely freaked out in a hospital bed and was almost strangled by a shapeshifter. When asked if she was okay she let's everyone know that she's back by responding with "Go get that bitch". She needs rescuing again in "Entrada" when she's completely immobilised and Strapped to An Operating Table and in "Lysergic Acid Diethylamide" when she's
 * Subverted in
 * Played With in "Brave New World, part 1".  sneaks up on Peter, dislocates his shoulder and proceeds to beat the crap out of him with a crowbar. Olivia is on the roof of another building, watching helplessly until
 * Dangerously Genre Savvy:
 * And now
 * Dark and Troubled Past:
 * Walter crossed several ethical boundaries in the name of Science before he was admitted St. Claire's Psychiatric Institution, including experimenting on children.
 * Also,
 * Don't forget Olivia! When she was just a toddler, and when she was 9, her stepfather would regularly beat her mother. Then, when she was still a teenager, her mother died. Then we come to the show...
 * Darkest Hour: As of "The Day We Died",
 * Data Crystal
 * A Day in the Limelight: "Northwest Passage" (2x21) focuses mainly on Peter trying to solve a Fringe case on his own in Washington State. And "Everything in Its Right Place" (4x17) revolves around our universe's Lincoln Lee assisting the other side's Fringe team.
 * Dead All Along:
 * Deadly Nosebleed: Congratulations, you're on an episode of Fringe! (Which does nothing for your life expectancy in the first place.) You get a nose bleed. Option 1, you're a walking radioactive bomb about to explode the heads of everyone (including yourself) in the immediate vicinity. Option 2, you're a about to turn into a giant were-porcupine and brutally rip apart everyone in the immediate vicinity. Option 3, you're infected with a thousand year old disease that wiped out the Mammoths. It will first drive you insane and then kill you. Worst case scenario, you're the harbinger of the Apocalypse. Don't get a nose bleed on Fringe.
 * Deadpan Snarker: Peter.

"Walter: (regretfully)You were young and I took advantage of you."
 * Death in the Clouds: The pilot episode has an airplane land with everyone on board dead from a biological weapon. They then have to figure out how the weapon got on board, why, where it came from, and is there more of it.
 * Death Seeker: Dana Gray in "Stowaway"
 * Demoted to Extra: While they had fairly important roles in Season 1, Nina Sharp and Broyles have been featured less and less as the series has gone on.
 * In Nina's case, this gets reversed significantly in Season 4.
 * Different World, Different Movies: The alternate universe has many examples of this.
 * Many DC Comics propherties are slighty different - Green Lantern and Green Arrow are Red Lantern and Red Arrow, Jonah Hex is a member of Justice League International instead of Guy Gardner, Superman died in Crisis on Infinite Earths instead of Supergirl and, apparently, The Dark Knight Returns and The Death of Superman have switched their main stars, becoming The Man of Steel Returns And The Death of Batman.
 * Batman clearly isn't all that popular in the Alternate Universe. Mantis is his replacement.
 * Eric Stoltz as Marty McFly in Back to The Future, obviously based on the fact that Stoltz was the original choice to play Marty in Real Life.
 * At one point, Broadway is shown, complete with a poster for the musical Dogs.
 * Disaster Dominoes: The villain of "The Plateau" can kill you with a pen. He doesn't have to use it as a weapon, either. He just leaves it on top of a mailbox
 * Dissonant Serenity
 * Common with Walter since he's the Cloudcuckoolander and Bunny Ears Lawyer.
 * Disposable Vagrant
 * Distant Finale: "Letters of Transit". Probably. Aired in a middle of storyline and ended with cliffhanger, to confuse you some more.
 * Does This Remind You of Anything?
 * Walter's conversation with his former patient/experimentee in "Momentum Deferred":
 * Walter's conversation with his former patient/experimentee in "Momentum Deferred":

"Walter: (excitedly) Yes! I can dominate her!"
 * In the same vein, Walter being asked if he can figure out the meaning of a complex formula in "Earthling":

"Peter: First times are always sloppy. Walter: It wasn't our first time."
 * Walter in "Jacksonville" talking about an experiment he and William Bell performed, and Peter makes a comment:


 * In "Marionette":
 * Dodge the Bullet
 * Averted in one episode. A mook tries to shoot Peter from behind at point blank range. Peter spins around in what looks like a Krav Maga move, redirecting the barrel so the bullet misses him, and grabs the gun out of his hand.
 * Peter also just barely dodges
 * Don't Tell Mama:
 * Doomsday Device: Walternate is developing one.
 * Do Androids Dream?: Or in this case, "Do Shapeshifters Dream of Electric Sheep?"
 * Dismantled MacGuffin: Walternate's Doomsday Device.
 * Director Allusion:
 * The alternate universe Fringe team from "Over There, Part 1" is filled with thinly veiled expies of Alias characters.
 * In Entrada 3x08, Alt-Broyles and Olivia have an exchange that mirrors, almost exactly, an exchange between Sydney Bristow and Vaughn.
 * Did They or Didn't They?:  This is never explained or even referred to again...although some of their meetings suddenly take on a whole new light.
 * Disposable Sex Worker: A serial killer targets prostitutes. Sounds familiar.
 * Double Standard: Broyles and Olivia are both The Stoic, but for some reason a lot of critics and fans figured that Broyles was supposed to be that way (which he is), but Anna Torv was just a bad actress. Then we met Alternate Olivia and everyone realized no, she's not.
 * Not to mention in 3x17, when we see Anna Torv doing a damn-near perfect emulation of the voice (at least as much as a woman can) and mannerisms of.
 * Dropped a Bridge on Him: Also
 * Drowning My Sorrows:
 * Becoming a pretty standard evening for Olivia.
 * In "A New Day in Old Town," Peter and Broyles do this when.
 * In "The Day We Died", future Peter does this after.
 * Drugs Are Bad:
 * Completely averted. Various cases are solved with the assistance of narcotics, Olivia Dunham spends much of the pilot on homemade LSD in a sensory deprivation tank, Walter is constantly using psychotropics (on himself and others), and one of his former test subjects, while decidedly loopy as a result of her LSD-induced trances, is entirely happy and expresses her gratitude to Walter years later - with a kiss.
 * Which gives you Ad of Win situations when it cuts to the commercials... this show is brought to you by.. The Council for a Drug Free America.
 * Oddly, the only drug that's given any sort of negative implications is marijuana. Though that's not the drug's fault, it's just the only drug Walter uses a crutch when depressed. Drowning My Sorrows would be too normal for Walter.
 * Which also leads to perhaps one of the very first scenes ever on Network television of someone using a bong--although we don't see the actual action, we hear the distinctive sound and see Walter put the bong down and exhale. In season 3, there's also a scene in which Walter and a security guard (played by Jorge Garcia) pass a bong back and forth while discussing such important subjects as Walter's newly invented cupcake flavor, baconberry.
 * Episode 3x19 is called "Lysergic Acid Diethylamide". That's LSD, kids. And as of now, Astrid is the only member of the central cast who hasn't been under the influence of drugs onscreen at some point.
 * Dysfunction Junction: There's Walter, a Mad Scientist (this isn't a hyperbole, he was previously locked up in a mental institution) with Dark and Troubled Past (he experimented on kids, okay). Then there's his estranged son Peter who despite having an IQ of 190 dropped out of high school and ended up living a nomadic life, which is still largely shrouded in mystery. And then there's Olivia whose FBI partner and lover is killed in the pilot, and to make matters worse she seems to have started to hallucinate him and even receive emails from him. And just when you thought it couldn't get any worse it turns out that . Astrid seems to be pretty normal, though some fans think she's hiding something. Broyles is still pretty mysterious, although he is known to be divorced.
 * Astrid is so non-dysfunctional that
 * Easter Egg:
 * "The Road Not Taken" (1x19): Walter was seen drinking a Slusho.
 * ""Momentum Deferred" (2x04)":  is also seen with a Slusho.
 * As are two Observers in "Peter".
 * A set of alternate universe DC Comics covers adorn Peter's apartment in "Over There:Part II."
 * The eye catches of each episode are a substitution cypher.
 * Every episode includes a visual clue to the next one. It may be a bit of graffiti, a sign on a shop, or a prop. Most are not recognizable before the subsequent episode is viewed, although some reference the upcoming episode's name.
 * Eleventh-Hour Superpower
 * Empathic Healer: James Heath, though he initially used his power to transfer his illness to others.
 * Enigmatic Minion: Nina Sharp, in the first two seasons.
 * Even Evil Has Standards: When Alt-Brandon suggests to Walternate that they should administer Cortexiphan to children, Walternate refuses vehemently. "There are lines I simply cannot cross."
 * Everything's Better with Cows
 * Evil Makeover: For Fringe Division's alternate universe counterparts i.e. darker hair, scars, form-fitting spandex and leather and /or suits.
 * Expository Hairstyle Change:
 * Fauxlivia always wears bangs. Olivia only wears bangs when she is wearing her hair brown.
 * Bangs is the common name for the hairstyle Fringe
 * Astrid and Peter in "The Day We Died". Not only is Peter's hair longer  but it's exactly the same as his fathers'.
 * Evilutionary Biologist: The Amber-verse ZFT cult contains many willing subjects thereof.
 * Eyecatch: They form a code, too.
 * Eye Scream: In "Marionette"
 * Also in "Do Shapeshifters Dream of Electric Sheep?" where Walter spends quite a while poking around in the eyesocket of a disabled shapeshifter.
 * Also in "Do Shapeshifters Dream of Electric Sheep?" where Walter spends quite a while poking around in the eyesocket of a disabled shapeshifter.

Tropes F-P
"Walter: Our mental patients. Mr. Slater, Mrs. Crampton, and Mr. Condom. Astrid: Gordon."
 * Fake American: Walter and Olivia's actors are both Australians and Peter is played by a Canadian.
 * Fake Memories:
 * Olivia is injected with . Sadly, it works.
 * Strangely, "The Plateau" shows us that.
 * And
 * Although based on
 * Fictional Document
 * The manifesto "ZFT", which stands for Zerstörung durch Fortschritte der Technologie, or Destruction through the Advancement of Technology. Apparently written by William Bell and Walter Bishop, it apparently is the manifesto of the group behind The Pattern.
 * ZFT has a counterpart in the Alternate Universe, where it's published under Walter Bishop's name with a Dianetics-like cover. However the text is very different: this version of the ZFT does not mention a parallel universe (ours) or its inhabitants.
 * Firefly of Doom:
 * From the episode "The Firefly". Three months after, Peter caught a firefly. Because he caught it, a little girl couldn't catch it, and stayed out later than she would have. Her father got worried, was late for work because he was looking for her. It started to rain, and he skidded through a red light on his way to work and hit someone on the crosswalk..
 * When Walter figures all of this out, he finally realizes exactly how much damage he's caused. He doesn't take it well..
 * 555: Used in "Snakehead" (2x09), after
 * Flatline Plotline: Newton uses one.
 * Fleeting Demographic Rule: ABC aired Strange World back in 1999. It had a very similar premise and was canceled after only 3 episodes. Strange World itself suffered from the Fleeting Demographic Rule, as it aired during the run of (and shared an executive producer with) the X-Files.
 * Flowers for Algernon Syndrome: In "The Plateau", a medical group developed a treatment to make a man with an IQ of 56 into a supergenius. Eventually, he got smart enough to predict the future, and when the researchers tried to reverse the effects, he started killing people with physics and psychology.
 * Foreshadowing: People from the parallel universe had a slightly different shadow in one episode (can't recall which), as seen when opening a door.
 * In the season 2 finale's alternate red title sequence, most of the Fringe science concepts that appear in the background are the same, or at least similar to the normal opening sequence. But if you look closely, you'll see that something called "First People" appears in the first few seconds.
 * Some of The Observer's lines can be interpreted as Foreshadowing.
 * "There is more than one of everything.":
 * "It must be difficult being a father":
 * In the fifteenth episode of Season 1 (five from the finale), Peter shows a kid one of his old G. I. Joe action figures, and comments, "You know, it's funny, I always remember his scar being on the other side." That's because
 * Foregone Conclusion: "Subject 13". It is truly heartbreaking to see  knowing that both of them are going to fail.
 * Ending to the Walter's story, suggested by Ella in "Brown Betty" at first looks like Deus Ex Machina, created by little girl who is not good in literature technique and wanted happy ending at any cost. However, it resembles the ending of season 3 - turns out Peter doesn't have to choose who live and who die after all.
 * Forgotten First Meeting: Peter met Olivia as a kid, but seems to have amnesia about this ever happening even though he is Olivia's boyfriend now. It is heavily implied by other Cortexiphan kids that the memory loss may have in fact been intentional on Walter and Bell's parts in an effort to cover up the drug trials.
 * For the Evulz: ZFT's apparent motive. That and showing off to the rest of the Mad Scientist community.
 * For Want of a Nail: The Alternate Universe is full of very slight differences to our own. For example: Cary Grant played Sam Spade in The Maltese Falcon, Martin Luther King Jr. is on the $20 and ID Cards are called "Show Me"s.
 * And the flashback episode has two of the Observers coming out of a movie theatre having just seen Back to The Future, starring Eric Stoltz, the actor originally chosen for the part because Michael J. Fox was having troubles negotiating out of his television contract. Apparently in the Alternate Universe, he never successfully cleared up his schedule.
 * Freudian Slip: Walter gets a really good one in in "Grey Matters".

"Walter: "I want to see Agent Dunham's face when she eats my pudding.""
 * Also see Walter's "vagenda" comment under Getting Crap Past the Radar.
 * Friday Night Death Slot: Was moved here midway through its third season. It's been renewed for season 4, meaning Fringe has actually survived the Friday Night Death Slot, making this only the third Friday/9PM show (after Millenium and Dollhouse) to get renewed since X-Files left.
 * Although it was likely a coincidence (the name comes from a line of dialogue from the episode), it is amusing that the first episode aired after its move to Friday was "The Firefly," sharing the name of Firefly, another science-fiction show that aired on FOX that was canceled after a move to a Friday timeslot.
 * Gaia's Lament: The Alternate Universe was suffering from this due to reality breaking down. With the activation of the bridge, it seems to be getting better.
 * Letters in Transit reveals that.
 * Gambit Roulette: One episode had an FBI agent who was infected with a life-threatening parasite which was cured at the very last second. Well, if you consider that the goal was to . But it still was a rather crazy plan.
 * The Plateau opens with a man assassinating a woman by balancing a ballpoint pen on top of a mailbox. How?  Just as planned.
 * Gentlemen Prefer Blondes: Peter does. Though he thinks Olivia makes a very sexy redhead.
 * Get a Hold of Yourself, Man!: Walter has to give Peter one of these in the final episode of Season 4. In all fairness, he had a fairly legitimate reason to Freak-Out.
 * Getting Crap Past the Radar: All the time.

"Walter: And I have no idea how to bring our Olivia back. It's all because of that temptress. She tricked my son with her carnal manipulation and he fell right into her vagenda! Astrid: Vagenda?"

"Walter: (at a subway stop) Kent Street. I frequented a massage parlor just around the corner. I used to get off right here. Peter: I sure hope you're talking about the station, Walter."


 * The Ghost: William Bell, including on his company's website. He's played in the season one finale by . For two minutes he returns in "Momentum Deferred". And then again in the season 2 finale.
 * Hallucinations: After sharing consciousness with him shortly before he died, Olivia saw visions of John Scott for much of the first season.
 * During the third season, Olivia's subconsciousness generates visions of Peter to combat her.
 * Here There Were Dragons: Walter and Bell theorized that the abilities that developed in the children they experimented on were once a part of normal physiology until they disappeared at some point. Walter suspects aliens.
 * Further hinted at in the "First People" theory which appears among the phrases in the alt-intro and in "6995 kHz".
 * Heroes Unlimited: The alternate Fringe Division.
 * Heroic Sacrifice:
 * Walter's backup plan
 * Nicholas Boone, who.
 * While helping Olivia escape from Walternate,
 * William Bell
 * Hollywood Cyborg: Nina Sharp.
 * Hollywood Science: And deliberately so.
 * Homicide Machines: One episode involved a guy who created powerful EM fields when he was under stress. For some reason this caused a printer to turn malevolent just long enough to kill his boss.
 * Hospitality for Heroes: A bartender in the alternate universe refuses to let Agent Broyles pay for his drink. This is because he recognizes Broyles as one of the law enforcement officials who helped deal with a major disaster (a gigantic vortex) years before; he tells Broyles that his money is no good there, because the world needs more heroes like him.
 * Hostage for Macguffin: Thomas Henry Newton secures his escape in "Grey Matters" by.
 * Hurting Hero: Walter has helped solve every case the Fringe team comes across. Though he spends most of his time munching on candy and dancing around dead bodies, it's hard to watch his scenes  and think he's happy. Then we have Olivia, whose life has been described by another character as "something of a nightmare."  Her life sucks.
 * I Choose to Stay: When the bridge between both universes is being closed, our side's Lincoln Lee chooses to stay in the alternate universe.
 * I Did What I Had to Do
 * Appears to be William Bell's justification for experimenting on children who ended up, in some cases, exploding, becoming suicidally depressed over their condition, and having their lives ruined by a ceaseless array of nightmarish visions.
 * Also the justification the colonel gave for detonating the subjects of Project Tin Man in "Fracture" (S2 E03).
 * I Know You Know I Know: The bad guy in "The Plateau" can use math to predict and manipulate the future. When Charlie and Olivia realize what it means for their investigation, they call Astrid and ask her if it's possible to compute whether he'll predict between their two choices. She says it's a mathematical impossibility, an infinite loop, and basically gives this trope. He can predict what they'll do since he knows that they know that he'll know he can predict them knowing that he can predict them, etc. Olivia just says "screw it" and decides to go to the hotel.
 * Subverted in the same episode in a rather clever way - the bad guy relies on Olivia following a particular protocol to keep the dominos of his plan falling - he thinks he knows she knows he knows. She of course DOESN'T know - being from the other universe, she's unfamiliar with the protocol.
 * Idiot Ball: Peter, third season.
 * This is made even worse by the fact that Peter was once a conman and claims to have a knack for reading people. Pull yourself together, Bishop.
 * trope Justified by Peter himself, in that he did noticed a lot of details being very off, but he kept rationalizing over them because of his love for Olivia.
 * Really, the fact that the Fringe group repeatedly gets tricked by alternates is just sad. Almost as bad is  And they fell for the shapeshifter switch yet again!
 * But when it comes down to it early in the third season when Peter is pursuing Fauxlivia, and she apparently takes a hostage, Peter immediately twigs that the hostage is a shapeshifter.
 * Also, it is in no way satisfactorily explained how the Olivia/Fauxlivia switcheroo happened anyway. From what we saw on screen there was no reason at all to think that it had happened, and it was only later that the differences started to become apparent. And of course the only person who spent any real time with her was Peter who was doinking her.
 * If I Do Not Return:
 * If I Do Not Return:
 * If I Do Not Return:

"Walter: That makes as much sense as anything else we've done. Astrid: That makes no sense at all! Walter: My point exactly."
 * I Just Want to Be Normal: "Baby Boy Brian" AKA Eugene underwent experiments that made him invisible and also put off a fatal condition. He spent his episode stealing other people's pigment to make himself visible again,
 * Impostor Exposing Test: The cyborg shapeshifters have mercury for blood. Blood screening is standard procedure when shapeshifters are at large.
 * Improbable Aiming Skills: Fauxlivia has an incredible knack for shooting people right between the eyes. Becomes a plot point in the Season 3 premiere, when Olivia pulls off an absolutely insane shot to a gas gauge with a handgun from a car moving at full speed.
 * Olivia  What this means is unclear. Later episodes have shown that she remembers all her time over there (she gives frequent guidance on how Fringe Division does things as events warrant it), she's just clear now that  . So that's okay, then. Probably.
 * Incredibly Lame Pun:
 * The title of the episode with the melting brains? "No-Brainer".
 * The one about rapid aging? "The Same Old Story".
 * People getting turned to dust? "Earthling".
 * Walternate.
 * Fauxlivia.
 * Most titles on the soundtracks are amazingly awful.
 * Incurable Cough of Death: Young Peter's mysterious terminal ailment. See also Soap Opera Disease.
 * Informed Ability: Peter's genius-level intelligence, most of the time. It doesn't help that he's often standing next to Walter, who makes pretty much everyone else seem stupid by comparison.
 * Inn Between the Worlds: Building where the machine is stored. From one end it is our universe, from other - it is alternate. From window you see clear sky, from another - clouds and zeppelins.
 * Insane Equals Violent: Averted in Walter's case. He was much more morally dubious when he was fully sane, but after his mental breakdown he becomes a harmless old man.
 * In-Series Nickname:
 * Insistent Terminology: Alternate Charlie has worms arachnids under his skin. They're NOT worms.
 * Interdimensional Travel Device: Several different versions, including: Walter's portal, which causes both universes to begin collapsing; William Bell's technique by which he pulled Olivia into the AU (usually only works on hybrid Super Soldiers who are designed to survive the crossing; it worked on Olivia because of her Cortexiphan-enhanced physiology); and the natural way, which is achieved by groups of Cortexiphan Kids being guided by Walter (and of the three, is clearly the least dangerous, to dimensions and dimension-crossers, but not without its kinks).
 * Interrogating the Dead: Mentioned in the pilot. Done in "In Which We Meet Mr. Jones" (1x7), and again in "Brave New World: Part 2" (4x22).
 * Intoxication Ensues: Walter (frequently).
 * Hilariously, Walter's fine during "Lysergic Acid Diethylamide". It's Peter and  (!) who are as high as kites.
 * In Which a Trope Is Described: "In Which We Meet Mr. Jones" (1x7).
 * Ironic Echo: Naturally, in a show about parallel universes, this trope pops up a lot. Examples include:
 * When Broyles is trying to convince Walter to help them deal with the machine in "The Box," he says that the government made similar arguments to Robert Oppenheimer (the scientist who led the Manhattan Project), and asks "how do you think he slept after his little invention had killed hundreds of thousands in a fraction of a second?" In "6:02 AM,"  Walternate also compares himself to Oppenheimer - and talks about the nightmares he had after Hiroshima and Nagasaki.
 * Jack Bauer Interrogation Technique: In the pilot, Peter uses a coffee mug to repeatedly smash the fingers of a suspect in order to get information.
 * Journey to the Center of the Mind: The pilot and "Lysergic Acid Diethylemide".
 * Karmic Death: In the first season finale, repeatedly attempts to . At the end of the episode, Peter !
 * Kick the Son of a Bitch: No one was really upset when one of the people treated with Cortexiphan  Or when Walter   Or when Fauxlivia
 * Killer Rabbit: Killer butterflies that cut! (Cutterflies?) A different kind of Butterfly of Doom...
 * Lampshade Hanging: Amongst others:

"Dr. Bishop: The only thing better than a cow is a human. Unless you need milk, then you really need a cow."
 * Laser-Guided Amnesia: An apparent side-effect of surviving the memory-transfer process used by the antagonist in "One Night In October" to take people's happy memories.
 * Late Arrival Spoiler: No advertisements, reviews, or discussions of Fringe bother to hide that there's an alternate universe involved. Mostly because it'd be impossible to explain otherwise by Season 3.
 * Law of Inverse Fertility:
 * Leitmotif: An ominous flute-theme usually plays when The Observers are featured.
 * Limited Wardrobe: Olivia wears almost entirely grey, white, and black.
 * Literal Change of Heart: In the "Brown Betty" episode.
 * Living Emotional Crutch: Peter to Walter.
 * Living Memory: After Olivia enters John Scott's subconscious via a Mental Fusion. In season 3,.
 * This happens again in season 4,
 * Loss of Identity: What Walternate forces on in the third season premiere.
 * Lost Superweapon: Newton seems to be tracking down the pieces of one.
 * Love Dodecahedron: Well... ... I think that's it.
 * Love Transcends Spacetime:
 * They've been separated by universes.  has been erased from existence.   They've crossed between universes, rewritten time lines and changed the future. Damn straight it transcends spacetime.
 * Most of the other examples in the series are Deconstructed, the elderly couple from "16B" who miss their alternate selves so much that they nearly break the universes, Alistair Peck and his time travel device and the man from "And Those We've Left Behind" who tries to make a bubble in time so that he can stay with his wife in the past before she can get early onset Alzheimer's and accidentally ends up creating dangerous time loops.
 * Love Is a Weakness: In one episode, Newton poisons and when cornered by Olivia, looking to bring Newton into custody, he reveals a three-step antidote process to counteract the poison, but he'll only agree to give Olivia the correct order for administering the antidote if she lets him go. Having to choose between arresting her target or saving her colleague and friend, she chooses to save . As promised, Newton upholds his end of the bargain and  is saved, but before he makes his break, he tells Olivia, "Now I know how weak you are."
 * Love Makes You Crazy:
 * Mad Scientist:
 * Walter Bishop, who's moved towards the 'endearingly confused and absent-minded' end of the spectrum rather than the 'really insane' side after leaving the asylum. He's also The Worm Guy and the Omnidisciplinary Scientist.
 * Mad Scientist:
 * Walter Bishop, who's moved towards the 'endearingly confused and absent-minded' end of the spectrum rather than the 'really insane' side after leaving the asylum. He's also The Worm Guy and the Omnidisciplinary Scientist.

"Walter: "Astral!" Astrid: "My name is ASTRID." Walter: "...Projection! Astral projection!""
 * Walter tends to shift from one end of the spectrum to another many times per episode. Rather than being inconsistent writing, this tends to make most anything involving Walter absolutely terrifying and remind you that the guy who spent 20 minutes talking about French toast is probably the most dangerous person in the whole show.
 * The audience is reminded forcibly in Letters of Transit where
 * William Bell, his ex-partner, might be on the 'take over the world' side after he parlayed his research with Bishop into a massive company with a nebulously-defined "specialty" (a billboard for the company says "What do we do? What don't we do?").
 * Many, many minor characters.
 * Mad Scientist's Beautiful Daughter: an uncommon male example in Peter Bishop. While he's far from the naïf, it's an interesting play on the trope.
 * Made of Iron: Olivia takes a lot of punishment in "Bound" and keeps on fighting.
 * The Observers.
 * To a lesser extent, the shapeshifters.
 * Magic From Technology: In 2x12 ("Johari Window"), wherein a whole town of mutants appear normal, Walter claims that an old friend once said that any sufficiently advanced technology is indistinguishable from magic.
 * Mass "Oh Crap": "6:02 am" has a few of these casually strewn about the place. It's that kind of episode.
 * Medium Blending: When Walter and Peter go into Olivia's mind, the world switches from live action to a rotoscoped, cel-shaded cartoon as soon as they meet William Bell. Apparently they couldn't get Leonard Nimoy to appear in person so they had to come up with something to use him in the episode. He was unwilling to go back on his retirement (announced following completion of the Fringe S2 finale), but he was prepared to do the voicework, hence the animation.
 * Mega Corp: Massive Dynamic: What don't we do?
 * The Men in Black: The Observer seems to play this very close to the classic understanding of the MIB image.
 * Mental Time Travel:
 * Mind Over Matter:
 * Mind Rape:
 * Mind Screw: '' "Death. I saw death. All of it. And it was me. And yes, there were drugs involved.
 * Makes a lot more sense when you realise that Broyles came face to face with.
 * Mirror Match: Olivia vs. Olivia in "Over There, Part 2".
 * Mismatched Eyes: Joseph Feller
 * Modesty Bedsheet
 * The Mole: . And not to mention . And as it turns out . And now . Again with . And then This show loves this trope.
 * Morality Chain: brought up in "One Night in October", when a forensic psychologist is brought to the other universe to profile his Serial Killer Evil Twin, and it turns out that the key difference between the two is that the psychologist, as a child, had met a woman who taught him to manage his destructive urges, while his counterpart never did. After.
 * Murder by Cremation:
 * Musical Episode: "Brown Betty" is a detective story Walter tells Ella while Olivia is . In it, Olivia is a hard-boiled pulpish detective, Walter is a Mad Scientist Marty Stu and the setting is an Anachronism Stew of 30's atmosphere and modern/future technology. This trope is played with when Rachel first starts singing, and Walter's voice comes out. This doesn't happen when other characters start singing however.
 * Mushroom Samba: "Lysergic Acid Diethylemide."
 * My God, What Have I Done?: This, followed immediately by Driven to Suicide, is the reaction of
 * Mysterious Past: Much of Walter's life before he was admitted St. Claire's is still shrouded in mystery. This also applies to Peter, who has a pretty sketchy background.
 * Mythology Gag: Take a shot every time one shows up in "Brown Betty". You'll be dead in less than half an hour.
 * Mysterious Watcher: The Observer. Played with during his first featured episode when . He's appeared in every ep so far, doubling as an Easter Egg. He has also appeared in other Fox programs, including NFL games, NBA games, and American Idol.
 * My Name Is Not Durwood:
 * Walter can never remember Astrid's name. The things he's called her thus far include such gems as Astral, Asterisk, Australis, Asteroid, Ostrich, and Ashram.
 * Walter can never remember Astrid's name. The things he's called her thus far include such gems as Astral, Asterisk, Australis, Asteroid, Ostrich, and Ashram.

"Walter: "Oh Astrid, I've found it.""
 * Subverted in "What Lies Below" (2x12) when he says Ash, but it turns out it's his Eureka Moment.
 * It looks like he's finally about to get her name right in "Brown Betty" when he's about to name her character in the story he's telling... but at the last second he names her Esther Figglesworth. Astrid's look of pure exasperation is priceless.
 * He does get it right in "The Road Not Taken" (1x19) - so naturally she wasn't there to hear it (he was alone in the lab at the time).

"Walter: Aspirin, we need to go to the market!"
 * He also remembers in "Snakehead" (2x09) -- when he's worried sick that he got her followed by gang members. She's not around then, either.
 * And, as of "The Box," we're back:

"Walter: Kennedy, help me!"
 * He finally gets it right, to her face, in "Do Shapeshifters Dream of Electric Sheep?", to her surprise. To both of their surprise, actually. Walter suggests it's because he's on a different blend of drugs at the time.
 * In response to Walter calling her Astro for the hundredth time, she calls him Wallie (3x19). The look on Walter's face is amazingly hilarious.
 * He gets it right again in "The Last Sam Weiss" - but only after being struck by lightning twice.
 * As of 4x02, it looks like is gonna join the party too.

"Olivia: I was hoping you'd have one of your weird connections. Peter: Weird connections? Olivia: They're always a little weird. Peter: Well, you're always a little weird."
 * Wrong President.
 * "Really? Claire? That doesn't even start with an A!"
 * Naked People Are Funny: Walter. Walter, Walter, Walter. Examples include Olivia finding out about his "cooking naked on Tuesdays" habit in "6:02 AM" - the hilarious way.
 * Name's the Same: Thomas Jerome Newton: see also The Man Who Fell to Earth. The similar background stories (They are not from this earth) makes this a deliberate Shout-Out
 * Neck Snap: David Robert Jones kills his lawyer this way as part of his escape plan.
 * Spinal fluid vampire lady, Valerie Boone, Valerie Boone. (She turned March into June).
 * The Needs of the Many:
 * Much of Walter's character development is centered around this trope.
 * The justification for using Amber. Hundreds of people trapped in a continue loop of fear... but the universe won't rip itself apart.
 * Nerdgasm: Brandon has one, with a combination of Properly Paranoid when researching Observer sightings.
 * Never Recycle A Room: Walter the Mad Scientist returns to his lab in the basement of a Harvard building after 17 years and just has to just dust the place down before getting back to work; not only has the space been left unused, but all his equipment is still there. Considering what he was working on leaving it alone might be the smartest thing a university has ever done. Walternate's lab wasn't recycled either.
 * The site in Jacksonville where William Bell and Walter . Handwaved by Bell buying it and then keeping it shut down.
 * Alistair Peck's lab.
 * Never Trust a Trailer: "Brown Betty" was advertised as a quirky, lighthearted Musical Episode. It really isn't. There's also only one real musical number.
 * And the trailer for the German premiere of this episode flanderized the noir aspect by being Deliberately Monochrome and utilizing "old movie"-style fonts. (Both also not to be found in the episode itself.)
 * Next Sunday AD: Presumably, given several references to President Obama, it's this as opposed to Twenty Minutes Into the Future.
 * Given that the Fringe division and everything it does is kept a secret from the public, it's possible that it's happening right now and you just don't know about it.
 * Nice Job Breaking It, Hero:
 * At least he admits that he is prone to this.
 * Nightmare Fetishist: Walter gets fired up rather than horrified by the grotesqueries they confront.
 * Ella is strangely nonplussed by the weird and freaky as well, which might foreshadow her.
 * Nightmare Fuel Coloring Book: In Season 4, a girl named Emily has visions of how people die,she carries a drawing pad with her so she can quick draw them out before she forgets them.
 * 90% of Your Brain: "Ability" averted this but replaced it with a similar concept. The trope was later invoked in the commercial for "Of Human Action", though not the episode itself. Further explained that at the special abilities that characterise the Cortexiphan patients . Walter suspects it was aliens who caused the loss of abilities.
 * No One Could Have Survived That: A woman falls from a building in episode 3x17 and walks away. Later we find out she was murdered eighteen months ago and escaped from the morgue.
 * No-Paper Future: The other universe is apparently like this, to the extent that the presence of a ballpoint pen at a crime scene is the most exotic thing about it. The clue leads them to a research center where mentally-handicapped patients have difficulty using computers and tend to write with pens instead.
 * Noir Episode: "Brown Betty" (2x20), also doubles as a Musical Episode.
 * Noodle Implements: Astrid does not want to know what Walter intends to do with a porn magazine and a portrait of George W. Bush.
 * Noodle Incident: Whatever case landed with arachnid eggs infesting his body.
 * Presumably the same case that left "our" version of the character with them, only they couldn't synthesise a cure, only a control measure.
 * No, You: From "Ability"
 * Noodle Incident: Whatever case landed with arachnid eggs infesting his body.
 * Presumably the same case that left "our" version of the character with them, only they couldn't synthesise a cure, only a control measure.
 * No, You: From "Ability"

"Orderly(to the exiting Dr. Samuels): Doctor Samuels, do you want me to give that little girl with the bike injury a Tetanus? Dr. Samuels: Not necessary. I don't think she's gonna make it. (Orderly gives her a confused look as the canister begins to release a gas that kills everyone in the ER)"
 * Orbital Kiss:
 * Oblivious Guilt Slinging:
 * Peter to Olivia and Walter towards the end of second season.
 * Olivia to Peter at the start of "Marionette."
 * Obstructive Bureaucrat: Sanford Harris deliberately uses his administrative leverage to hinder Olivia's work, as revenge for a past conviction on sexual harassment charges . "I have lots of red tape."
 * Oh Crap:
 * Nina Sharp's expression in "Peter"   screams this trope.
 * The Observer in "Letters of Transit." Causally observing the device Walter made... and then realising what it is.
 * Omnidisciplinary Scientist: Walter specializes in neurology, genetic manipulation, amateur surgery, and basement time/space machines. And pharmacology : Let's make some LSD!
 * In reality more than a few fringe scientists do cross-train to that extent. At least one of the cold fusion groups has a medical doctor as a consultant. This is because in reality "fringe" science is stuff considered so laughable that almost nobody studies it(you can pick up everything currently known about, say, Phrenology from one thick book) so there's very little to actually learn, almost none of which is actually useful. It's not hard to be a fringe science Renaissance Man - what's hard is being a practical fringe scientist. This makes some promising research projects(such as cold fusion) almost impossible to staff because the nutcase-to-Worm Guy ratio is just absurd - few mainstream scientists realize what they're looking at if anomalous data appears, and most nutcases think they've cured cancer if they drop bleach on the petri dish. Case in point, radioastronomers spent decades enhancing and tweaking their instruments trying to eliminate what they thought was earth-based "noise" before they realized they had discovered cosmic microwave background radiation.
 * Once an Episode:
 * The Observer, the cow.
 * Played with in Brown Betty. Several Observers show up in that episode at the same time as generic Mooks, as well as a polka-dot cow in Bizarro!Walter's lab.
 * All episodes also contain a link to the next episode, for example the Beacon from "The Arrival" is shown on a sign in The Ghost Network.
 * One Degree of Separation: It turns out that.
 * Orifice Evacuation: In "Bound" an immunologist is killed by a slug which escapes through his mouth.
 * The Other Darrin: Incredibly, Gene, the team cow. The cow used in the pilot had to be replaced because of livestock restrictions.
 * Other Me Annoys Me
 * Our Vampires Are Different: They suck spinal fluid, not blood. And they go clubbing!
 * Out of Order: "Unearthed", which aired during the run of Season 2, was clearly supposed to be a Season 1 episode, as.
 * Peggy Sue: In . A vast Deconstruction, of course.
 * People Puppets: In "Of Human Action", has this power. He uses it brutally, forcing a policewoman to kill herself and her fellow officers, and has a man cut his own fingers off for trying to escape. Trying to resist causes lesions on your brain, but he can be incapacitated for a very short time with a special device that blanks his brainwaves.
 * Pensieve Flashback: Olivia going into the tank to view John Scott's memories. Played with in that John is able to interact with Olivia (even though Walter says this is not possible).
 * Perma-Stubble: Peter.
 * Pet the Dog: The ordinarily stoic and humorless Broyles has a moment at the beginning and ending of "Earthling."
 * Fauxlivia has one of these moments every time
 * Phone Trace Race: Done in "Stowaway" in a failed effort to track a Death Seeker on a train with a bomb.
 * Planning with Props: Walter explains to Broyles how he intends to attenuate the fringe disturbances caused by the two doomsday machines by using a glass pane, magnets and iron filings.
 * Playing with Fire:
 * "The Road Not Taken" is about a woman who has acquired pyrokinetic powers.
 * Plot-Relevant Age-Up:
 * Pointless Doomsday Device:
 * Portmanteau: Since the introduction of the alternate universe, there have been many, many examples of Portmanteau, in-universe ("Walternate") and out. The winner of most portmanteaus? Easily the two Olivias. Over there Olivia? Altlivia, Nolivia, Bolivia, Fauxlivia, Holivia, Theirlivia, Otherlivia. This universe's Olivia? A-livia, Ourlivia. And then there is Bellivia, for when However, the best portmanteau of the series isn't a name, but a concept introduced by our Dr. Walter Bishop - vagenda (See above Getting Crap Past the Radar)
 * Portal Cut: The manner in which dies. As well, this is how Nina loses her arm.
 * Powered by a Forsaken Child:
 * The device that designed seems to require  to power it in some way.
 * Power Perversion Potential: When the Cortexaphan test subjects gain control over their powers, they naturally start using them to enhance their sex lives.
 * Precursors:
 * Walternate's Doomsday Device is described as ancient, and according to the trailer for 6955 kHz, the titular signal is millions of years old.
 * subverted.
 * Preemptive Declaration: From S4/E9 "Enemy of my Enemy", An agent of  is a doctor in an Emergency Room. She calls up Fringe Division, asks them to listen closely, and walks out the ER (leaving a canister behind her):
 * Preemptive Declaration: From S4/E9 "Enemy of my Enemy", An agent of  is a doctor in an Emergency Room. She calls up Fringe Division, asks them to listen closely, and walks out the ER (leaving a canister behind her):


 * Pretty Little Headshots
 * Product Placement: The season 2 finale features our heroes chowing down on KFC and snacking on Twizzlers. Incidentally, Walter knows the eleven secret ingredients. And he has for over thirty years.
 * Rather blatant placement for Ford and Sprint products show up in a few episodes, but not to a level of egregiousness.
 * Season 3 takes place in both universes. The alternate universe is technologically much much more advanced than ours - yet in both universes Windows 7 is state of the art and widely used.
 * But then of course we now know that Windows 8's desktop mode looks exactly the same as Windows 7 (as do many other elements) and that it'll be the dominating OS for a good decade or so.
 * Psychic Link:
 * The pilot features a link between Agent Dunham and John Scott in order to find a missing, unidentified suspect. The drug cocktail used to "open her consciousness" involves ketamine and lysergic acid, also known as LSD. Which.
 * Also happens in episode 17, "Bad Dreams".
 * Psychic Nosebleed:
 * As a general rule, nosebleed in Fringe equals really bad.
 * Psycho Strings:  gets these in his introduction in Season 4 to let us know that he might not be the man he was in the other timeline.
 * Putting on the Reich: The uniforms of the non-Fringe Division police officers in  resemble Chinese and North Korean uniforms rather than that of the Nazis though.

Tropes R-Z
"Walter: Dammit! Why can't I get a current? Astrid: Maybe you reversed the poles?"
 * Real Life Writes the Plot:
 * Replacement Goldfish:
 * Red Shirt: Police officers and non-Fringe division FBI agents are frequently killed off by the Monster of the Week.
 * Examples include:
 * "The Cure" (1x6)
 * "Ability" (1x14)
 * "Night of Desirable Objects" (2x2)
 * "Fracture" (2x3)
 * and 'especially' "Of Human Action" (2x7):
 * Ret-Gone:
 * Retraux:
 * The opening of "Peter", is made to look as if it was made in the 80's. As well, the floating text from flashbacks to 1985 is in a different font.
 * They compare 80's fringe science to modern fringe science - all of it seemed absurd, but some of it actually came to pass, while the rest just turned out to be bunk. The implication is pretty obvious: yeah, a lot of it is crazy, but the good stuff will change everything!
 * Retro Universe: Walter's fairy tale world in "Brown Betty." The cars are old, men wear fedoras, and yet everyone still carries a cell phone.
 * Return to Shooter:
 * The Reveal:
 * Last bit of the season 1 finale, when the camera pulls around to reveal.
 * Closing shot of the season 1 finale, when the camera pulls around to reveal
 * The last part of "A New Day in the Old Town", when we learn that
 * As of "Over There" part 1, we now know that
 * The ending scene of the season 2 finale, where we see.
 * End of "The Last Sam Weiss," where we see tha Peter is at a 9/11 memorial - installed 10 years in the future.
 * End of "The Day We Died," where the Observers casually inform us that
 * Reverse Polarity: In 3.06:
 * End of "The Day We Died," where the Observers casually inform us that
 * Reverse Polarity: In 3.06:

"'Walter: Peter was really worried about you when you were gone. Peter: Walter... Walter: You were. Peter: Well, of course I was worried. Walter: He was *really* worried."
 * Romance on the Set: Anna Torv married Mark Valley, who played her partner and lover in the pilot, but they separated after a year.
 * Room Full of Crazy: Seen on several occasions. Walter's lab may also qualify.
 * Rule of Cool: Are half the things that occur on Fringe even remotely plausibly? Not by a longshot. Are they awesome? Hell yes.
 * Running Gag: Peter "maybe knowing a guy" who can do this or that faster than the FBI could.
 * Also, Walter getting Astrid's name wrong.
 * Charlante: "THEY'RE NOT WORMS!"
 * The image cutting to a pan of the Massive Dynamic HQ after someone says that they need information, technology, or that they've found a link to someone important. It might as well be a recurring gag given how often it happens.
 * Save Both Worlds
 * Sacrificial Lion:
 * Science Is Bad: Sort of. According to the creators the entire ethos of the show is that scientists haven't had any sense of their own purpose since the space race ended and that's bound to cause all kinds of problems.
 * Serial Escalation: Part of the second season premiere.
 * Schizo-Tech: The alternate universe has modern cell phones by 1985, but still uses zeppelins. Tablet computers are so widespread that paper is obsolete, but they haven't cured smallpox.
 * "Brown Betty" cranks this Up to Eleven. It's supposed to come off as an old-school 1950's Film Noir musical, but alas, we have laser pens, cellphones, and laptops. ...The cellphones are touch-pad PDA's which are absurdly huge and look like giant slabs of metal, and the laptops are built out of wood.
 * Secret Test: The Observer's ultimate goal in "Firefly". Нe wanted to know if
 * Set Right What Once Went Wrong:
 * In S2-E16, "Peter", one of the Observers wanders through Walternate's lab and distracts him so
 * "White Tulip".
 * She Cleans Up Nicely: Olivia puts on a cocktail dress to inflitrate a black-tie fundraiser.
 * She Fu: Impressively averted with Olivia. While she usually favors taking the bad guys down with a few well-placed bullets, the times she does get into a fistfight she both takes and dishes out pretty convincing punches. Of course, she is a former Marine and fancy backflips would not be in her combat repertoire.
 * Shipper on Deck: Walter, for Peter & Olivia: "Do you two want to use the room?" Lately he's wondered aloud if his son and Olivia got married she would call him "Dad".
 * Oh, Walter is just a giant ball of mischief when it comes to shipping Peter and Olivia. "Of course, condoms are never 100 per cent effective (pause) You two should be aware of that." and we have:

 * Oh, Walter is just a giant ball of mischief when it comes to shipping Peter and Olivia. "Of course, condoms are never 100 per cent effective (pause) You two should be aware of that." and we have:

"Walter: I was worried, too, when you were taken. Olivia: Thank you, Walter. (she walks away) Walter: (after a pause) Not as much as him, of course. Peter: Walter.... Walter: It's true."
 * ... later in the same episode ...

"Peter: The best lie, the one that's easiest to remember with consistency, is the one that's based on the truth. Whenever I would do this, I would base it on my own last name. Bishop. So Peter King. Peter Knight."
 * Nina Sharp is a pretty avid Peter and Olivia shipper. For good reason. Shipping is really Serious Business where those two are concerned.
 * September also ships Peter and Olivia.
 * Astrid tries to set up Olivia and Lincoln in Season 4.
 * In a really weird turn of events,   seems to ship Lincoln and Olivia from the amber timeline. He even buys Lincoln a pair of hip glasses to woo her with.  Alternate universes, altered time lines and upcoming apocalypses sure make hysterical Love Triangles.
 * Shoo Out the New Guy: Anyone else remember Amy Jessup? Nope, well you're not alone. For the star of season 2 there was an announcement of a new member joining Fringe Division who saw a possible religious/supernatural connection to the Pattern. She ended up being in only two episodes.
 * Shoot the Fuel Tank: Olivia does this in the Season 3 premier. From a moving taxi. Henry Higgins, the taxi driver, is suitably impressed.
 * Shout-Out: There are a lot of shoutouts to famous scientists and science fiction authors.
 * In one episode Charlie suggests that Olivia see psychiatrist Dr Katz. Must be some Comedy Central watchers on staff.
 * A conspiracy theorist in "The Road Not Taken" thinks that the entire Z.F.T. conspiracy is caused by "renegade Romulans from the future here to change the timeline" - The actor who played the conspiracy theorist is Clint Howard, and he played a similar (read "exactly the same") character in an episode of Star Trek Deep Space Nine.
 * At one point a copy of Arthur C. Clarke's novel Childhood's End can be seen on a shelf; it now appears that
 * The pilot of is loaded with references to the movie Altered States in the form of Dr. Walter Bishop's shady history as a Mad Scientist. Both Bishop and the Mad Scientist in the movie both combined powerful drugs with sensory deprivation tanks and are naive cloudcuckoolanders with bad social skills. Even their last names are similar, suggesting that Bishop's character might have been inspired in part by Eddie Jessop of Altered States. Furthermore, Amy Jessop in Season 2 has the same last name as Eddie Jessop.
 * Considering Blair Brown is in the cast, this could count as a marginal case of Actor Allusion.
 * That movie was cited as one of the show's influences.
 * And finally in the season 2 premiere we have X-Files references! First, one character is shown to be watching The X-Files immediately before he dies. Later, a senator makes an in-show reference to "X-designated cases," implying that both the X Files (as in what Mulder and Scully investigated) and "The X-Files" (as in the TV show) exist in the Fringe verse.
 * In 2x02, it's lupus.
 * In Episode 1x07, Mitchel Loeb refers to "Agents Coscarelli and Scrimm," who are presumably named for horror director Don Coscarelli and actor Angus Scrimm. Scrimm starred as "The Tall Man" in Coscarelli's Phantasm series.
 * People turning to dust like in "Color Out Of Space".
 * There's also Dunwich Hospital in the episode "Grey Matters" - and there's a Dr. West working there.
 * The Simpsons Pez dispenser.
 * He didn't want to have to kill those cops and F.B.I. agents, they just got in the way...
 * In "August", the Fringe team is shown pictures from throughout history that show that one specific man has always been present at major historical events.
 * David Robert Jones is the real name of David Bowie. Thomas Jerome Newton is Bowie's character (the alien) in The Man Who Fell to Earth.
 * Olivia's license plate reads 1C3P01.
 * Along the same lines, she had the nickname "Han" in high school due to being a loner ("going solo").
 * Da-da DA-duh-DA-duh-DA-duh-dun
 * The whole plot involving the time traveler in "White Tulip" is essentially the plot of Ludo's Rock Opera "The Broken Bride".
 * Alternate Olivia's ringtone is "Science Fiction Double Feature".
 * Astrid Farnsworth might be a Futurama shout out, or it might be a shout out to the real Farnsworth.* Almost certainly the latter...by extension if nothing else, since Futurama's Farnsworth is a Shout-Out to the good Dr. Philo.
 * A possible one: In 2x13 ("What Lies Below") the CDC shows Olivia a model for what would happen in the disease were allowed to spread. It shows it spreading over the whole world with infected areas in red and non-infected in black. Eventually the whole map is red...with the sole exception of Madagascar.
 * William Bell and Thomas Henry Newton.
 * A doctor in "The Plateau" mentions "nootropics". Olivia promptly pipes up "Smart drugs, right?"
 * After failing to take the identity of a Daniel Verona, a man takes a pill to fake his death.
 * The Fringe team finds that someone has dug something up out of a hole in a basement. Walter thinks it would be delightful were it a box with tiny legs that got up and ran away.
 * Speaking of which, here's a somewhat far-fetched one from "Jacksonville"...This is one Ted Pratchett. Could this be a really twisted double allusion to the "trousers of time" theory? (Warning: the image is fairly disturbing.)
 * It could be a reference to this scene from Planetary/Batman: Night on Earth.
 * The glasses Walter wears in "The Firefly" are said to have been made by a friend of Walter's, a Dr. Jacoby from Washington state (who wore similar glasses in that show).
 * "The Firefly" was the first episode in the Friday Night Death Slot.
 * "6B" has Walter flipping a coin that always lands on heads. The hotel where this takes place is even named the Rosencrantz.
 * Young Peter in "Subject 13" is seen looking at an original series Battlestar Galactica board game.
 * In the second episode of season one,  Sounds like Space: Above and Beyond, another Friday Night Death Slot show. On Fox, no less.
 * William Bell (played by Leonard Nimoy) used the alias "Dr. Paris" to operate on Walter. Leonard Nimoy's character in the original TV series "Mission:Impossible" was called "The Great Paris."
 * Another Cortexiphan trial patient is identified as Cameron James
 * Walter names a lab mouse John. This doesn't seem notable, until he reveals -- literally; he'd turned it invisible -- that he has a second mouse: Yoko.
 * Amberverse David Robert Jones shows us the advantages of having one's body dismantled and reassembled at the atomic level.
 * The creepy town of Westfield in "Welcome to Westfield" contains multiple references, including Silent Hill, The Walking Dead, and The Crazies.
 * The victim from "Dream Logic" dies of acute exhaustion. He's from Seattle. Coincidence? I think not.
 * Shown Their Work: In "Everything In Its Right Place" alternate-universe Fringe Division uses textbook military suppression tactics. Which makes sense, as they have more of a military bent than the standard version.
 * Sinister Geometry: Massive Dynamic's interior decorator must be an interesting guy.
 * That's the interior of the Royal Ontario Museum's Michael Lee-Chin Crystal, the inside actually do look like that.
 * Smug Snake: Sanford Harris.
 * Special Edition Title: Fringe loves to change its opening sequence; for starters, the list of "fringe topics" that appear changes every season as well as for certain special episodes, all listed on the Quotes page. The style also changes depending on the episode:
 * First and most dramatically, episodes "Peter" and "Subject 13" were set in the 80s. The opening replaced some of the modern "fringe" science subjects with now-commonplace sciences such as DNA profiling and in vitro fertilisation. It was also set to an 80s-sounding version of the theme and similarly retro graphics, and a slightly grainy effect as if recorded on VHS tape.
 * A red color scheme is used for opening credits of episodes taking place in the parallel universe, instead of the usual blue. The season 2 fringe topic "parallel universes" was replaced by "first people" in those episodes.
 * The opening of season 3 episode "Entrada" alternates between red and blue, since it shares time about equally in both universes.
 * A grey color scheme was used for the season 3 episode "The Day We Died" (set ) and featured even more advanced fringe sciences, such as dual maternity and thought extraction. Ominously, "water" and "hope" are also listed as fringe topics.
 * An amber color scheme is used for season 4 episodes taking place.
 * The season 4 episode "Letters of Transit" (set ) goes a different route with its code-words. None of them are science-related but instead cover concepts like "community," "joy," and "free will."
 * Spontaneous Human Combustion:
 * A Season One episode explored this. People who were used in experiments involving Pyrokinesis would burst into flames and explode if they couldn't focus their attention on other things around them when their power builds up inside of them.
 * Later, in Season Four, a fringe incident is initially believed to involve several people spontaneously combusting after their bodies exerted too much energy (with others in the affected area needing to stand perfectly still to avoid meeting the same fate), but it is revealed to have been spurned by nanotechnology entering the affected persons' bloodstream.
 * Spy Speak: Where does the Gentleman live? Little Hill.
 * Stable Time Loop:.
 * Implied in White Tulip.
 * Star-Crossed Lovers: How one of the Australian promos described  If the trope is subverted or not remains to be seen.
 * Staring Kid: So very much. You could actually make a drinking game out of this if you watched only the teasers.
 * Start of Darkness:
 * Stalker with a Crush:
 * A Storm Is Coming: spoken word for word by
 * Strapped to An Operating Table: Olivia is abducted and strapped down by  in Season 1; she is later strapped down again in Season 3 and almost de-brainified by Alt-Brandon once the Secretary decided she Had Outlived Her Usefulness.
 * Stupid Jetpack Hitler: Walter's father worked for the Nazis while spying for Americans.
 * Stylistic Suck: "Subject 13" took the Whole-Episode Flashback concept further than normal and made even the HD broadcast look like it was shot on mid-80s hardware.
 * Sweet Tooth: Walter.
 * Synchronization: In the episode
 * In the fourth season episode "The Consultant," is experimenting with a device that causes accidents in one universe and kills the counterparts of any victims in the other world in the exact same way. Ever see someone die in a plane crash while in the middle of a business meeting? Not pretty.
 * Team Mom: Blue!Astrid has taken this role to the team
 * Team Pet: Gene, the cow.
 * Technology Marches On:
 * After 17 years locked up in a mental institution, Walter is a bit behind the times. "Don't forget to check out his floppy disks!"
 * Even before being committed, he apparently preferred to use dated technology in his everyday life, all the more surprising for a cutting-edge scientist. He has a typewriter and his record collection is pre-CD.
 * Tele Frag: happens in "Jacksonville" (2x15) to an entire building when it(and the people inside) are merged with their Alternate Universe counterparts.
 * Terror At Make Out Point: The episode "The Man From The Other Side" begins with two teens getting stoned in a car (presumably before or after making out) who quickly have their identities stolen by interdimensional shapeshifters.
 * Trapped in Another World:
 * The Omniscient Council of Vagueness: The Observers.
 * The Reveal: "The Secretary" of the shadowy alternate universe organization is . He's known as "The Secretary" because he's.
 * The Virus: "What Lies Below"(2x13)
 * Themed Aliases: Though Peter hasn't used many aliases during the run of the show, he still knows enough to lampshade this trope.
 * The Omniscient Council of Vagueness: The Observers.
 * The Reveal: "The Secretary" of the shadowy alternate universe organization is . He's known as "The Secretary" because he's.
 * The Virus: "What Lies Below"(2x13)
 * Themed Aliases: Though Peter hasn't used many aliases during the run of the show, he still knows enough to lampshade this trope.
 * Themed Aliases: Though Peter hasn't used many aliases during the run of the show, he still knows enough to lampshade this trope.

" I'm doing what you wanted. I'm turning on the lights."
 * Those Wacky Nazis: "The Bishop Revival."
 * Time Travel: "White Tulip".
 * The Observers are able to move through and outside of time. For a long time, their abilities, origins, and motives are a total mystery. They are eventually revealed.
 * Timey-Wimey Ball: "White Tulip", again.
 * Title Drop: By Walter in "The Day We Died."
 * Title In: Played with.
 * Titles are presented as big, 3D letters hovering in the air during establishing shots.
 * One establishing shot of a location in Iraq had the letters more or less aligned with the city's grid as US choppers flew over it. Then the angle changed so the camera was on the ground, and the letters are actually reversed, with the choppers in the air on the other side.
 * Other times, they are reflected in nearby bodies of water.
 * Raindrops have been seen splattering on contact with them.
 * They cast shadows on occaision.
 * When they title in action that occur in the '80s, they turn into the stereotypical old fashioned computer font.
 * When titles are shown for the alternate universe Fringe team, they're the normal plain-text-on-screen style.
 * In another episode, the big floating letters that spelled "Manhatan" with only one "T" were.
 * Tonight Someone Dies: "The Day We Died". The producers hinted on that and also announced that they will introduce a rookie FBI agent. The promo for the episode featured a coffin. And it's also named "The Day We Died". In the middle of the episode  got shot by , but that's okay, because it was in the Bad Future. What really counts is that  The rookie FBI agent turns out to be
 * Town with a Dark Secret:
 * Tranquil Fury:  She disapproves. Violently.

"Richard: You're threatening me? After seeing what I'm willing to do to my own brother? : Well let me assure you, we'd be happy to treat you as family too."
 * Transhuman: Many examples, including the Cortexiphan kids, subjects of other experiments in human augmentation, and.
 * Traveling At the Speed of Plot: The team can navigate the Boston-New York-Washington megapolis in a matter of moments.
 * In The Consultant, Colonel Broyles gets his "Show Me" card scanned at Liberty Island. After they get an alert about this, Bolivia and Agent Lee make it from Fringe HQ in Manhatan to Liberty Island in the time it takes Broyles to walk down the hallway.
 * Triumphant Reprise:
 * "Funeral Pyre Straits" is played in Season 3 during  It's basically the worst case scenario. A louder, triumphant version is played in Season 4 when Olivia saves Peter in a particularly creative way.
 * Fauxlivia's theme was played as a dark string piece when Fauxlivia was up to no good and as a sad piano piece when . More upbeat versions are also played when
 * Twenty Minutes Into the Future: The look and feel of the Alternate Universe has shades of this but, as mentioned above, the show is more of a Next Sunday AD setting.
 * At the end of The Last Sam Weiss.
 * Letters in Transit takes place in.
 * Tyke Bomb:
 * Ugly Guy, Hot Wife: The episode "Midnight" had such a combo with the revelation that the defected scientist from ZFT
 * Unresolved Sexual Tension: Peter and Olivia. In the beginning, it was simple, and it was obvious that there was some attraction.
 * Then came Altlivia,
 * As of 6B:
 * Vehicle Vanish: The Observer does this.
 * Viking Funeral:  in "The Day We Died".
 * Villains Act, Heroes React: Peter disapproves of this trope.
 * Viral Marketing: In JJ Abrams fashion. Massive Dynamic has their own website.
 * Vomit Indiscretion Shot
 * Flight 627. What happened to the passengers is not pretty.
 * The shot of 's belly crawling with maggots under the skin.
 * Wacky Parent, Serious Child: Walter and Peter, the latter being more the snarky type rather than the responsible one.
 * Weaksauce Weakness: The cure for malevolent hell Ebola from 75,000 years ago... is
 * Weirdness Magnet Lampshaded: When pressed by Olivia about Massive Dynamics' suspicious tendency to be involved in Pattern cases, Nina counters by noting the oddity that the cases also seem to be clustered in the taskforce's backyard. Explained in the season one finale as being caused by "soft spots," which cause weird events to radiate out from them. These soft spots are apparently caused by the advancement of science and technology.
 * "Well Done, Son" Guy:
 * Well-Intentioned Extremist: The Alternate Fringe Division sees the deaths of at least 10,000 people (themselves included) acceptable losses in order to quarantine the dimensional tears. Furthermore, it's believed that only one of the two dimensions can survive the upcoming cataclysm, so unless someone figures out a way to Save Both Worlds, pretty much any atrocity inflicted on the opposing side is arguably justifiable.
 * Western Terrorists: ZFT.
 * We Didn't Start the Billy Joel Parodies: The episode "The Road Not Taken" got one (lyrics). ("Susan Pratt started the fire / It wasn't God nor Jesus / It was pyrokinesis")
 * We Wait: Said in the first episode when Olivia is in the isolation tank.
 * Wham! Episode:
 * "There's More Than One of Everything"(1x20).
 * "Momentum Deferred"(2x04) follows up with more revelations from along with setting up the rest of the season.
 * For a while, Fringe lacked a true wham episode since the plot attempting to travel to the other universe built slowly. Then we got the season two finale "Over There"
 * This was quickly followed by "Olivia" (3x01) where
 * Entrada (3x08) wrapped up what felt like a season's worth of plot in one action-packed episode.
 * "Lysergic Acid Diethylamide" (3x19) has an ending that shoves it very firmly into Wham territory.
 * "6:02 AM EST". Walternate . Sam Weiss . Fringe events . Peter . Fauxlivia . Walter . It doesn't get much whammier than this...
 * "The Last Sam Weiss" (3x21): Olivia . Peter wakes up.
 * "The Day We Died" (3x22):  For those of you keeping track, the final four Season 3 episodes are all listed here.
 * Back To Where You've Never Been.  The promo said that the episode would explain everything. THEY LIED.
 * Brave New World, part 1.
 * Wham! Line: A strange one since it is not spoken but written on a plaque:.
 * Similar example: Peter Bishop,.
 * "The FBI ceased to exist over a decade ago."
 * Also,, spoken almost cheerfully by   with regards to the man with the X T-shirt.
 * "They don't remember him." "Of course not. "
 * "It is the same - " *collapses*
 * An early one from the Pilot, when Olivia is listening to a tape of her suspect being threatened:
 * An early one from the Pilot, when Olivia is listening to a tape of her suspect being threatened:

"Peter: Well, if there's something strange in your neighborhood... Walter: Who You Gonna Call?? ''"
 * What Do You Mean Its Not Symbolic -- The Eye Catches show a peculiarly changed item, such as a cross-section of an apple with fetuses (feti?) as the seeds, or a frog with the Greek letter Phi, or Φ, printed on it, along with a point of light. The Other Wiki says Phi is used as a symbol for several interesting subjects, such as electric or magnetic flux in physics, a shorthand representation for an aromatic functional group in organic chemistry (which relates directly to the pilot episode), and a sentence in first-order logic.
 * Not to mention the number (1.618...) represented by Phi, and, by extension, the Golden Ratio, although the Golden Ratio is usually denoted by the lowercase version of Phi (φ). Still, it's relation to science and nature fits right in with the theme of the show.
 * What Happened to the Mouse?:
 * Season 1 hinted at Peter's connections to the Boston mob several times. After a mobster had been informed about Peter being back in town at the end of "The Dreamscape", the sub-plot has apparently been dropped entirely.
 * Agent Amy Jessup, after appearing in two episodes of season 2 and investigating a possible connection between The Pattern and biblical prophecies, disappeared from the show without an explanation. Maybe the producers realized that the general fan reaction was not favorable. Putting her storyline into the Aborted Arc pile.
 * Season 1's main bad guy organization, ZFT, appears to have vanished entirely after the death of its high-profile member David Robert Jones in the season 1 finale.
 * Although it is arguable that the whole point of ZFT was to activate Olivia and have her realise her talents so that she could eventually defend the universe. And having done that they could get back to regular crazy science instead of murdering people with science.
 * Although ZFT the book resurfaces in the Season 2 finale. In the other universe it's apparently a propaganda book written by Secretary of Defense.
 * Peter's deal with Nina Sharp in "The Cure" seems to have been forgotten.
 * Although this of course may yet show back up...
 * What happened to Tyler?
 * What Could Have Been: In-universe examples with the parallel universe, glimpsed in backgrounds and the like. Including:
 * Back to The Future starring Eric Stotlz (in a Shout-Out to the circumstances of The Other Marty)
 * The West Wing season 11, complete with an Obama lookalike on the poster and a slightly different logo ("the" is on the right hand side, not in the middle)
 * Comic books such as The Red Lantern and ''The Death of Batman - see them here
 * Dogs, now enjoying its 18th year on Broadway.
 * Queen Diana is visiting the States apparently. Depressing both IRL and in-universe, since it suggests an early death for Queen Elizabeth II.
 * Len Bias apparently having more than 20 great years with the Boston Celtics, and still being good enough to win the NBA MVP award in his 40s.
 * What Is This Thing You Call Love?: Played straight with September's line "I believe you call it love."
 * What Measure Is a Non-Human?: Raised in "Reciprocity" when Walter finds out that Peter
 * Do Shapeshifters Dream Of Electric Sheep?
 * What the Hell, Hero?: Walter gets a lot of this. Particularly during season 2. And usually for good reason.
 * "Marionette" has
 * Whole-Plot Reference: Whether unintentional or a deliberate reference, the episode "White Tulip" (2x18) borrows heavily from the plot of The Broken Bride by the band Ludo:
 * Who You Gonna Call?:
 * Well, yeah... it's a section of the FBI geared specifically towards the (un)conventionally inexplicable. Actually spoken by Walter Bishop in the episode "The Road Not Taken":

"Peter: You know, there are easier ways to kill people."
 * The alternate-universe Fringe Division even moreso, as it operates openly, has a larger budget, more personnel, and reports directly to the Secretary of Defense.
 * Why Am I Ticking?
 * The pyrokinetic twins.
 * The Bellini's Lymphocymia sufferers in "The Cure."
 * Project Tin Man in "Fracture."
 * The victims of in "Brave New World."
 * Why Don't You Just Shoot Him?:
 * Lampshaded:


 * "Earthling," in which.
 * Wild Child: Seen in "Inner Child."
 * Wild Mass Guessing: It's as though Abrams is reading Fringe's WMG page and saying Sure, why not?
 * Woobie, Destroyer of Worlds:
 * Walternate.
 * Eugene.
 * Worm Sign: The burrowing mutant in "The Night of Desirable Objects" (S2 Ep2)has this in one scene.
 * Yank the Dog's Chain: Frequently. Especially to Olivia. The most Egregious of which... "This is my favourite time of day. So full of promise." Cue
 * You Have Outlived Your Usefulness:
 * Also,.
 * Your Head Asplode: "The Cure." And "The Box."
 * Your Mind Makes It Real: The effect of a hallucinogenic. Beyond the "standard" die-in-a-dream-die-for-real effect, due to Mind Over Matter phlebotinum you'd die in the exact same manner. So a guy who hallucinates an attack by glass-winged butterflies has his body manifest cuts.
 * But then Averted in "Lysergic Acid Diethylamide", which falls just short of a Whole-Plot Reference to Inception, complete with the fact that dying in the "dream" just causes you to wake up.
 * Arguably more just an example of a Journey to the Center of the Mind.
 * Zeerust: Walter's old lab stuff.
 * Zeppelins from Another World
 * The Alternate Universe's Empire State Building's dirigible docking station is active unlike in our world where it was only used once. Also, this is played so straight it's basically an Invoked Trope.
 * In "Over There: Part 1", zeppelins are used twice to tell the viewers (and sometimes, the characters), "Hey, we're in the other universe." Again, played so straight that the producers must be tropers themselves.
 * In "Subject 13", Walter realizes young Olivia's crossed over when he sees she's drawn a picture of a zeppelin.
