A House Divided
"A house divided against itself cannot stand."—Abraham Lincoln, paraphrasing the above.
The opposite of Locked in a Room: the ensemble of diverse characters starts to argue and turn against each other during intense situations. E.g. being boarded up in a house/building/store when there are rampaging viruses/zombies/aliens/vampires/Werewolves/Jehovah's witnesses or what have you looming outside (or inside) trying to get to you. Which leads to paranoia, frustration, and disagreement among the group when it comes to fixing the dilemma. Patience starts to run short, the ensemble is starting to get on each others nerves, and things quickly get out of hand and possibly implode.
When this occurs against something threatening to wipe out humanity as a whole (such as the ever-popular Zombie Apocalypse) this usually leads to An Aesop for the survivors (or the audience) about how we need to look beyond our differences and focus on the big picture, or a scathing indictment of humanity's self-destructiveness and how we can sometimes be even worse than the monsters we're fighting. This trope is also a good way to showcase the darker side of characters under stressful situations whom are otherwise good people. This also can be caused by clashing egos, But mostly it's due in part to conflicting personalities.
This trope is named for a famous Biblical quote that Lincoln later borrowed about how "a house divided against itself cannot stand," though it is also referred to in writing circles as "Scorpions in a Box."
This is frequently combined with an Ontological Mystery.
Typical Character types that are found in this trope are:
- Action Girl, Probably resents the Damsel.
- Agent Mulder
- Agent Scully
- Bald Black Leader Guy
- Black Best Friend (or just the token black)
- Crazy Survivalist, on occasion fights with both the Jerkass and the Marty Stu
- Damsel Scrappy
- Damsel in Distress
- Dying Like Animals, the whole farm and Zoo in fact...
- The Jerkass... obviously.
- Marty Stu, always at war with the Jerkass
- Similarly an Ideal Hero
- The Millstone
- Nietzsche Wannabe,
- Ignored Expert, Only Sane Man, and Cassandra Truth
- The Load
- Psycho Party Member
- Token Evil Teammate/Token Good Teammate
- Zombie Infectee, sometimes the main cause of the division
Anime and Manga
- Infinite Ryvius. After the adults die, it takes all of two episodes for the children to start turning on one another. The vicious infighting continues even in the middle of battles.
- In Naruto, there's a hardlined military faction that works against members of Konoha that follow the teachings of the 3rd Hokage, which includes, among others, the main character and the 5th Hokage. There are also other factions in the Land of Fire who want the fifth gone. None of these groups particularly liked the third Hokage either.
- This came out particularly strongly in the first arc of Umineko no Naku Koro ni because the characters are stuck in a Closed Circle where Everyone Is a Suspect.
- In the RS arc of Pokémon Special, the Gym leaders realize that there's a terrorist group out there planning to screw over Hoenn. Since Aqua and Magma work against each other, the Gym Leaders argue about which group are the real bad guys, not realizing that though the two teams have opposing goals, both groups are terrorists. The Gym Leaders probably would have duked it out between themselves if not for the fact that Groudon and Kyogre start destroying the region.
- Though, in all fairness, Tate and Liza weren't entangled due to their duty to guard the Red and Blue Orbs, and Norman knew better and refused to take sides. Shame Sapphire wasn't at this particular meeting, or she could have vouched against them both, being a witness to the heinous deeds of both groups.
- Happens to the girls holed up in the lighthouse in the Battle Royale manga.
- And they all wind up dead, especially the instigator. Oh so much.
- Marvel's Civil War arc has caused this among its heroes.
- So far the group in The Walking Dead comic manages to avoid this... for the most part.
- The core members have learned to trust each other over the constant fear that the other people aren't making the best decisions. Every time someone new comes into the fold, the tension surfaces. Time, and sometimes a death or two, will put things back to 'normal'.
- Used in a strip in Doctor Who Magazine in which a group of minor villains that the Doctor has previously defeated gather together in a deserted space-station to plan a final attack that will finish him once and for all. One of them dies horribly, and as the others begin dying one by one afterward, it seems (to them, anyway) as if the Doctor has infiltrated their midst in disguise and is picking them off one by one. Finally, the last couple — paranoid that either one of them could be the Doctor in disguise — kill each other... and at that point, the Doctor arrives, not recognizing any of them. Turns out the first death was just an accident with a faulty machine and the other deaths were just everyone picking each other off out of sheer paranoia.
- The Blair Witch Project.
- Cabin Fever.
- In Night of the Living Dead Ben and the Mr. Cooper fight over the use of the cellar. Ben believes it should just be a last option, with Mr. Cooper thinking it's their only option and threatens to close everybody else out of the cellar if they don't make up their mind. Eventually things come to a boil in both versions of the film. Unfortunately, it turns out that Cooper may have been right. In the underrated remake Ben and Cooper get into a shoot out within the besieged house over the fact that Cooper wouldn't let anyone kill his daughter.
- Lampshaded in Pirates of the Caribbean: At World's End, and referred to as "Cuttlefish in a barrel".
- Also averted, partly because they were Genre Savvy enough to know about it.
- In John Carpenter's 1982 version of The Thing, The researchers at Outpost 31 turn on each other when they realized the alien could imitate anyone. Paranoia and intense tension build up, Resulting in one of the most bone chilling endings ever made.
- The 1951 version, The Thing from Another World, centers on a conflict between the scientists and the military over how to best deal with the alien creature (which is a more conventional monster rather than a shape-shifter).
- Saw II.
- Partially subverted in Saw V, in that Jigsaw not only does nothing to promote his captives' squabbling, but arranges things so that cooperation would've greatly reduced the casualties. Too bad the prisoners were so determined to act this trope out straight...
- Shaun of the Dead - Shaun: As Bertrand Russell once said, "The only thing that will redeem mankind is cooperation." I think we can all appreciate the relevance of that now.
- You read that on a beer mat, didn't you?
- The latter portion of 28 Days Later.
- Cube. Although the eponymous Cube is filled with lethal booby traps, they only kill two of the seven characters.
- The Descent. Mostly between Sarah and Juno, especially after the former found out the latter took the group caving/spelunking in a dangerous uncharted cave that's filled with flesh eating subterranean mutants, in a misguided effort to reunite the group. Not to mention the fact that Juno also slept with Sarah's deceased baby daddy. Juno's Good Intentions not only contributed to her friend Sarah's breakdown . But also led her friends to their doom.
- Juno also accidentally mortally wounded one of her friends (Beth) in the cave thinking she was one of the cave dwelling monsters. And left her there to die and tried to cover it up. When Sarah comes across the injured Beth, Beth explains what happened (including info about the affair Juno had) . And tells Sarah not to trust Juno, essentially putting the proverbial nail in the coffin of Sarah and Juno's friendship.. Of course karma is a bitch, as Juno sufferers the consequences (unfairly or not).
- A literal example (well actually an apartment complex) in the films REC, and Quarantine. The inhabitants never fully reach this level seeing as how the infection happens so fast people rarely get the chance to argue with one another, although they came dangerously close to this trope during the initial panic.
- The Beast of War is a forgotten war movie from 1988, depicting the struggle between a Soviet tank crew and their mujahadeen opponents. Not all the conflict takes place outside the tank. The commander shoots his Afghan translator, convinced he's working with the enemy, and when another soldier threatens to report the killing he's tied to a rock and booby-trapped for the mujahadeen to find.
- In Night at the Museum 2: Battle of the Smithsonian, Larry remembers some advice the (animated) Lincoln Memorial gave him, and begins taunting the villains and playing them against each other. Ultimately, their inability to work together proves to be the ultimate reason for their defeat.
Lincoln Memorial: A house divided cannot stand.
- The Stephen King story and movie, The Mist. A military project code-named 'Operation Arrowhead' has gone awry and a quaint Maine town is shrouded in mist that happens to be filled with flesh eating monsters from another dimension. A lucky few residents are able to barricade themselves in the local supermarket. The Fundamentalist Mrs. Carmody preaches that this is all an act of God for landing people on the moon and homosexuality. Yes, really. Yet as people start getting picked off by the monsters most of the people in the store let their fear get the better of them and start listening to Mrs. Carmody's sermons, save for a level headed group that finds its self outcast and fearing for their lives after Mrs. Carmody has her followers sacrifice one of the townspeople to the monsters. When they decide that they would rather face the monsters then face a religious nut, Mrs. Carmody tries to stop them and utters her final words, 'Kill them all!' before she is finally put in her place with a Boom! Headshot!.
- Happens to a small group of teenagers on a plane in the film Altitude.
- Survival of the Dead. Only it's more like an island divided. The O'Flynns and the Muldoons have such a sharp family rivalry that they don't even pay attention to the zombies killing everyone around them during the final showdown at the end. And they don't let up, either. Not even when they become infected themselves. Tsk, tsk.
- M.Night Shyamalan's Devil takes this beyond the average person's tolerance with an elevator full of people slowly being killed off.
- The post-apocalyptic film The Divide is fueled by this trope.
- The story Who Goes There? by John W. Campbell, which provided the inspiration for the movie The Thing. A shape-shifting alien is thawed out, and proceeds to start killing people in an isolated Antarctic research station. Everybody is understandably paranoid and scared to death. Besides being eaten to death of course.
- Much of Tanya Huff's Smoke and Mirrors—in which a television crew gets locked in a Haunted House—consists of this trope; they don't descend to killing each other, but...not by much.
- In the Stephen King short story The Mist, this happens to around 80 people stuck in a supermarket. The main threat is a deeply religious woman who urges the others to make a blood sacrifice to stop the monsters outside.
- Will Navidson and his significant other Karen move into the house because they are trying to avert this trope, but the strange happenings in House of Leaves don't allow for that sort of healing.
- In Terry Pratchett's Discworld, wizards have a weird, formalized version of this. Wizards get along about as well as a sackful of soggy cats, something apparently programmed into them at a genetic level (or at least the level that passes for genetics on the Disc). Unseen University was created to redirect that murderous energy into a strict hierarchy where a cutting note could do nearly as much damage to one's opponent as a hurled fireball, but with a much smaller risk of bystanders being turned into charcoal (or possibly haddocks). They still cheerfully murder one another with creative booby traps, but things have settled somewhat now, since the current head of the University has proven himself more or less unkillable (and he sleeps with two loaded crossbows, although he's a kind man, and probably won't shoot you in both ears).
- Machiavelli in Discourses on Livy believes that this is one of the reasons for a republic's strength, since it allows the right leader to come tot he fore at the right time.
- Seen in Star Trek Gemworld during a crisis, when the six races of Gemworld, and their leaders, fail to work together successfully. Barclay calls them out on it, by appealing to the Good Old Ways:
"This is not how your ancestors survived, by ignoring a problem...The inhabitants of Gemworld have gotten soft. You prefer to bicker and fix blame instead of finding a solution. I'm sorry... that's not how the Ancients would have faced this... The question is - will you act like your ancestors? Will you do what it takes to survive? Or would you prefer to hide in this room and bicker?”
- In Babylon 5, the alliance against the Shadows turned in against itself when it was left leaderless by Sheridan's death. Order was only restored when The Messiah returned from the dead.
- Happens from time to time on Lost. Often a main character will stop the fighting and remind everyone that there are other threats to their survival without them turning on each other. Jack, Locke, and Hurley have delivered such speeches, beginning with Jack's "live together, die alone" speech in an early episode.
- Pretty much the entire episode of Midnight from Doctor Who is an extended Scorpion Box. it's easily one of the most disturbing Doctor Who episodes ever aired.
- Also the plot of "Edge of Destruction", a first Doctor serial.
- The Twilight Zone episode "The Monsters Are Due on Maple Street".
- The Outer Limits episode "Abduction", An alien kidnaps five high school students, and tells them that one must be killed. They must decide which of them it will be. And of course they're from completely different social groups. Ray, a typical jock, Danielle, the hottest girl in school, Jason, a stereotypical geek, Brianna, a devout religious girl, and Cody, a social outcast. So needless to say they don't get along. But then again it was a test. And the ensemble was picked for that very reason.
- The 4400 episode No Exit features most of the major characters being Locked in a Room... that's trying to kill them. Their bickering and political differences lead to Shawn and Meghan's deaths, and in the end Jordan and Tom need to work past their personal differences to save the others.
- In Angel when the cast were regressed to their 17 year old versions and trapped in the hotel. They all belong to the types listed in the header: Angel (Marty Stu), Gunn (Bald Black Leader Guy), Fred (Damsel in Distress), Cordelia (Damsel Scrappy by that time), and Wesley (Jerkass).
- Warhammer 40,000's Imperium intentionally invokes this trope with every institution, organization and military unit mistrusting everyone else. This does leave them with a bureaucratic nightmare where military or humanitary aid for worlds may arrive a century after it was needed, but it also keeps the human race comparably safe from the danger of a high-ranking defector. This lesson was learned after two bloody civil wars, one of them tearing humanity out of its beginning golden age.
- This also happens to foster an environment where different parts of the military occasionally go to war with each other, however...
- Girl Genius has a lot o this going, especially in the House of Storm Lords/Knights of Jove/Storm King Conspiracy (which heavily overlap, but are not the same). As explained by Wooster, they were already splintered by the time the real Heterodyne heir was discovered and Baron Wulfenbach was wounded. Immediately before which, deaths of Snarlantz of Passholdt and Prince Aaronev VI of Sturmhalten (with subsequent blockade of their lands) had to at very least tear the communications further. Only from what we know, there were followers of Tarvek, followers of Martellus, the fools who were art of the plan with Zola, but launched it prematurely as their own bid for power or at least some gold, and Lord Selnikov with his army -- and Lucrezia's loyalists against everyone else.
- As such they all acted independently and even competed, thus while this did drive them to show as much force as they can more or less simultaneously, they didn't leave reserves and inevitable Gambit Pileups made a lot of mess; of course, once the "Storm King" factions moved, Lucrezia's followers and random opportunists figured it's an opening and also joined the fray, finally making enough of a mess to tear both Baron's Pax Transylvania and each other's plans into shreds.
- The Trolls from Homestuck eventually become this, as shown by this update and the ones following it.
- A subversion of the villainous version happens in Survival of the Fittest - Burton Harris/Ken Lawson plays off the paranoia and reservations of a group of students hanging out in a cottage in order to get the entire uneasy alliance to dissolve. Burton/Ken wasn't exactly a villain though, just a dick who thought that the place was too crowded.
- One Hundred Yard Stare: Episode four sees the girls turning into this trope.
