Earlier in a story, opinion/assumption X is associated with Alice, and opinion/assumption Y is associated with Bob. Later in the story, Y is associated with Alice and X is associated with Bob instead.

Note that "perspective" is not literally a physical perspective but is used to refer to either opinions or assumptions; this can apply to either.

May in some cases result in an IronicEcho. UnrequitedLoveSwitcheroo is a Romantic SubTrope.[[note]]Wherein either X ''or'' Y represents a one-sided crush.[[/note]] See also HourglassPlot. Not to be confused with PerspectiveFlip.

[[folder:{{Anime}} and {{Manga}}]]
* In ''Manga/{{Phoenix}}: Karma'', the artisan Akanemaru first meets Gao as a fugitive and offers him his fire; Gao, disfigured from birth, rewards Akanemaru for his kindness by maiming him out of spite. By the end of the story, Gao has redeemed himself and become a master artisan in his own right, while Akanemaru has let his success get to his head and become a cold, heartless bastard: when Gao bests him in a competition, Akanemaru reveals Gao's sordid past, resulting in him losing his one good arm.
* In ''Anime/YuGIOhArcV'' For the first two seasons, everyone tries to get [[NinetiesAntiHero Shun Kurosaki]] to become a team player and work with the Lancers. [[spoiler: After CharacterDevelopment allowing Shun to [[TookALevelInKindness Take A Level In Kindness]], he tries to do this for [[Anime/YuGiOhZexal Kaito]], who became far worse than he was.]]

* One [[UsefulNotes/TheBronzeAgeOfComicBooks Bronze Age]] ''Franchise/{{Batman}}'' story begins with Batman unsuccessfully trying to convince the parole board not to let Penguin out of prison. When Penguin gets out, Batman keeps a close eye on him, convinced that his apparently innocent activities are [[FalselyReformedVillain a front for some new criminal scheme]]. Sure enough, he exposes Penguin's plan... to give legitimate jobs to ex-cons, which he had to do secretly because associating with them at all was a parole violation. The story [[BookEnds ends]] with Batman unsuccessfully trying to convince the parole board not to send Penguin back to prison.

[[folder:{{Film}} -- Animated]]
* ''Disney/{{Bolt}}'' involves, earlier on, Bolt believing that [[spoiler:Penny's love for him was sincere]], and Mittens believing that it wasn't. Later in the movie, [[spoiler:Bolt sees Penny hugging another dog, assuming himself to have been replaced, and walking away before Penny can even see him... then Mittens sees Penny sobbing at the real Bolt not being there, and figures she was wrong about Penny. After this point, it's Mittens who thinks Penny's love for Bolt is sincere, and Bolt believing that it wasn't.]]
* ''WesternAnimation/ToyStory3'' involves, earlier on, Woody and Buzz trying to encourage the rest of the toys to get ready to go into the attic. Towards the end of the movie, Woody is more skeptical of the attic idea, while the rest of the toys are more open to it; though Buzz's attitude seems relatively unchanged. [[spoiler:Of course, as things turn out, none of them end up in the attic anyway.]]

[[folder:{{Film}} -- Live Action]]
* The 1991 film ''Film/HeSaidSheSaid'', starts with two people having contrasting opinions about whether or not to expand a certain roadway. At the end, they both correct themselves, switching to the other person's opinion.
* In the 2009 film ''Film/FiveHundredDaysOfSummer'', Tom is hopelessly romantic, while Summer does not believe in love. By the end of the movie, their dispositions toward love are inverted.
* In the Spanish movie ''Anacleto: Agente Secreto'', Adolfo is a man with no ambition beyond spending the weekend in the sofa while watching a movie, and his girlfriend Katia dumps him because she want to have adventures, and is planning to go to India. By the end of the movie, after such an adventure, Adolfo is all fired up about becoming a spy like his father, but Katia says she just wants to spend the weekend watching movies from the sofa... and dumps him again.
* Early in the Franchise/MarvelCinematicUniverse, [[ComicBook/CaptainAmerica Steve Rogers]] just wants to join the Army and do his part for his country, and [[ComicBook/IronMan Tony Stark]] is an egotist who has little use for authority. By the time of ''Film/CaptainAmericaCivilWar'', the fallout from his reckless actions have made Tony believe that the Avengers need to be subject to oversight while Steve, having witnessed how corrupted and obstructive governing bodies have become in the modern day, distrusts the idea, to the point where the two end up leading opposing factions of the team.

* The premise of the book ''Flipped''.
* In the book ''The Pig, The Prince, And The Unicorn'', when Quadroped (the titular Pig) [[spoiler:meets Goriel, TheDragon of the piece, who doesn't kill Quadroped, but instead shows him that the assumed-till-then BlackAndWhiteMorality is more GreyAndGrayMorality.]]

* In ''Series/StarTrekTheOriginalSeries'', the Klingons were conniving, sneaky infiltrators and [[TheChessmaster Chessmasters]] while the Romulans were honour-obsessed ProudWarriorRace {{Blood Knight}}s. In ''Series/StarTrekTheNextGeneration'' and all other ''Franchise/StarTrek'', including ''Series/StarTrekEnterprise'' which is set before the original series, the two cultures' outlooks and personalities are exactly reversed, with no internal explanation.
* One episode of ''Series/ItsAlwaysSunnyInPhiladelphia'' revolves around the gang trying to fix the gun problem. Dennis and Dee think that guns should be more regulated, while Mac and Charlie believe the only way to fight bad guys with guns is with more guns. By episode's end, Dennis and Dee want more guns on the streets and Mac and Charlie think they should be banned. They lament that they hadn't gotten together halfway through, because they could have worked together.
* During the run of ''Series/{{Roseanne}}'', the characterizations of Becky and Darlene almost completely reversed through the course of the seasons. Early on, Becky was a high-achieving straight "A" student whereas it was considered a major accomplishment if Darlene could keep a "C" average and once used the excuse that the reason she skipped one class was because her friend forgot to wake her up after another class. However, as the girls got older, Darlene entered college and became a very successful student and creative writer whereas Becky completely dropped out of school to get married and ended up living in a trailer.
** In the finale, it was explained that the final season (and various other parts) of the show was [[AllJustADream just a story]] that Series/{{Roseanne}} had written. Among other things, it is revealed that in reality, Darlene got married and dropped out of school while Becky was successful
* ''Series/DrQuinnMedicineWoman'' seems to have an example of this at first glance. Sully is generally more progressive than most of the other men in town about almost every issue: ethnical minorities, women's rights, controversial books in the new town library, the theory of evolution, homosexuality... But when it comes to the railway and other building projects, Sully is the one fighting "progress" and the other men are supporting it. It becomes a [[SubvertedTrope subverted]] case though: Sully has good reasons to dislike ''that'' kind of "progress", because he knows how this would affect the local Cheyennes, all the animals in the nearby forest and the nature scenes. Which would have been a radical viewpoint in the 1860s/1870s. The other men on the other hand will only want to make a quick profit, and will not care too much about if other values could be lost. So it means that Sully ''still'' is the progressive one and the other men the more conservative ones.
* A variation occurs on ''Series/{{Friends}}''. After Rachel and Phoebe's apartment is destroyed in a fire, they must live with their friends with one living with Monica and Chandler and the other living with Joey. Monica's is seen as the better option due to its cleanliness and her tendency to spoil guests while Joey's is an unkempt pigsty. Eventually it's decide that Phoebe will stay at Monica's and Rachel with Joey. However, Phoebe gets frustrated by Monica's rules for keeping the apartment clean and the constant attention. Meanwhile, Rachel actually enjoys living with Joey because she can be as untidy as she wants and has fun playing games with him that make the apartment messier.

* The titular character from ''Theatre/LadyWindermeresFan'' thinks Mrs Erlynne is a wicked woman; her husband, however, thinks there is good in her, allows her to [[spoiler:blackmail him]] because he thinks she deserves another chance, and has her at the house as a guest against his wife's wishes. Mrs Erlynne's act of [[spoiler:saving Lady Windermere from disgrace at the cost of her own second chance in society]] reverses the situation: Lady Windermere is deeply grateful to her, and is forced to dispense with her previous black-and-white worldview; her husband, having witnessed Mrs Erlynne [[spoiler:disgracing herself in a gentleman's chambers]] after all he's done for her, considers her beyond the MoralEventHorizon. [[spoiler:He comes around, though.]]

* In ''VideoGame/PokemonBlackAndWhite'', Cheren is concerned with ToBeAMaster, analyzing every opponent he meets to give him an advantage, while Bianca is somewhat aimless and clumsy in her battles, becoming a Trainer largely to try to figure out what to do with her life. By the end of the game, Cheren has reached a roadblock and is questioning if he even has the personality to be a champion, while Bianca comes to terms with her father, who didn't want her going into the dangerous world on her own, and has decided her path for her future, assisting Professor Juniper in the lab.
* It's subtle, but this a major theme in ''VideoGame/FinalFantasyX'' and its sequel, ''VideoGame/FinalFantasyX2''. In the first game, Tidus (the protagonist) is a selfish, wangsty teen who is [[TrappedInAnotherWorld more concerned with returning home]] than the imminent destruction of Spira. It isn't until he learns that his LoveInterest (Yuna) will have to sacrifice herself to defeat [[BigBad Sin]] that he starts to undergo CharacterDevelopment and ''refuses'' to let Yuna sacrifice herself to save the world. There's a conversation roughly a third of the way through the game which highlights their different philosophies, in which Tidus questions whether sacrificing your life, even when [[RegularlyScheduledEvil the Big Bad is sure to come back]] is worth it and Yuna disagrees and says she feels ''any'' sacrifice is worth bringing just a ''little'' happiness to the world. In the end, Tidus has to make a HeroicSacrifice ''himself'' in order to destroy Sin and break the ViciousCycle, ''devastating'' Yuna, who had been prepared to sacrifice herself, but not her loved ones. Then, in the sequel, Yuna is a HeartbrokenBadass ActionGirl whose perspectives on sacrifice have completely changed. When another character offers to sacrifice himself in order to defeat the new BigBad, Yuna shoots his plan down ''immediately'', stating how much she's grown to hate having to [[PyrrhicVictory "lose in order to win"]]. To make this juxtaposition even more poignant, Yuna's outfit throughout the second game is a direct homage to her dead love.
* The Alliance in ''VideoGame/WorldOfWarcraft'' has hotheaded King Varian Wrynn and pacifist Lady Jaina Proudmoore. Varian has had a troubled history with the Horde and along with Warchief Garrosh Hellscream are the main reasons why the two are at war now; while Jaina is leader of Theramore, and worked with then Warchief Thrall to fight against the Burning Legion in ''VideoGame/WarcraftIII''. As of ''Mists of Pandaria'', Varian has grown into a ReasonableAuthorityFigure and no longer views the whole Horde as evil, just specific elements like Hellscream. Meanwhile Jaina saw Theramore destroyed by a Horde attack, and needed to be talked down before she tried to destroy Orgrimmar; then she was made leader of the neutral city of Dalaran, believing that it remained a beacon of hope for mending Alliance/Horde relations, until the Horde used it as a jumping point to invade Darnassus, which has broken her faith completely.
* ''VideoGame/XCOMEnemyUnknown'' put the player in charge of a globally-supported XCOM, backed and funded by a coalition of nations across the world, fighting against a secretive and subversive alien threat. The 2016 sequel, ''VideoGame/XCOM2'', is set in an AlternateTimeline of sorts (it's tacitly assumed that [[NintendoHard the ending you almost certainly got in your first playthrough]] is canon) where all human resistance including XCOM was annihilated by the invading aliens, who consequently [[VichyEarth put the earth under Advent, a sinister pro-alien government]] - XCOM lives on as an underground movement painted as traitors and terrorists by Advent propaganda, and leading the fightback. This extends to gameplay - in the original, your troops had to seek out and destroy alien forces hidden on the map, whereas in the sequel, it's ''your'' XCOM troops who are hidden and the aliens enemies are the ones standing in plain sight, just begging to be ambushed.

* There's an ''Webcomic/ArthurKingOfTimeAndSpace'' space-arc strip that starts with Lancelot claiming that God made the universe to be perfect as it is, and Guenevere countering that change is good, because it's how things progress. Arthur tells Merlin he wishes they could see things from each others' perspective. The next panel has Lancelot saying that if a certain species is dying it's God's will, and Guenevere responding that on the contrary, things have to be preserved.
* In ''Webcomic/GeneralProtectionFault'', Nick starts a WideEyedIdealist who is also [[HorribleJudgeOfCharacter prone to trusting people he shouldn't]], like he does with Trudy. By contrast, Ki is far more hesitant to trust people and dislikes and distrusts Trudy from the beginning. After Trudy's plans are thwarted in the Surreptitious Machinations arc, Nick feels guilty about having been blind to Trudy's nature, while Ki admits that there is some good in Trudy, [[spoiler:since she couldn't bring herself to kill Nick even after he rejected her]]. Some time later, when faced with the issue of whether to trust Trish in spite of several red flags, Nick refuses to trust her based on his experiences with Trudy, while Ki wonders if Nick is right and she should trust people more, deciding to trust Trish. After the two reach their conclusions [[http://www.gpf-comics.com/archive/2004/07/16 in this strip]], Nick lampshades it with the above quote.

* The Wiki/SCPFoundation {{verse}} is rife with these, both within individual SCP's and tales and in the broader lore, but one of the most shining examples is the Church of the Broken God. Once the [=CotBG=] was seen as a zealous cult of {{Machine Worship}}ers and the Foundation as the only group preventing them from initiating an apocalypse out of blind adherence to doctrine. Several years of plot development and lore exploration later, however, and there is a growing possibility that the Foundation's blind adherence to the doctrine of contain first, dissect and ask questions later, has been crippling the keepers of humanity's only weapon against one of the greatest threats the foundation has ever known.

* In one episode of ''WesternAnimation/DextersLaboratory'', Dee Dee crushes a bunch of ants, because she thinks they're filthy. Dexter, who find ants interesting, shrinks them both down to ant size so Dee Dee can get a better idea of their society. After some adventures, they return to normal size, at which point Dee Dee happily thanks Dexter for showing her just how cool ants really are - while Dexter is squashing them.
* In ''WesternAnimation/ThePowerpuffGirls'' episode "Mommy Fearest", when the girls attempt to sneak into the house after after fighting crime despite the Professor's new wife forbidding them to, the lights turn on to reveal her angrily waiting for them on the couch. When the girls later figure it out that it's really Sedusa, it then goes to Sedusa sneaking into the house with a bag of jewels and the girls turning on the light while looking smugly on the couch.
* ''WesternAnimation/TheNewAdventuresOfWinnieThePooh'' has the episode "Tigger Got Your Tail," where Tigger leads Pooh and Piglet on a hunt for invisible "Nobodies" who have been stealing things. Rabbit dismisses this as nonsense, claiming "There's a reasonable explanation for everything"...until his vegetables starts disappearing. At the end, when everything is recovered (crows were stealing the vegetables, Piglet's painting had blown away, and Tigger had just lost his voice), Pooh tells Rabbit that he was right...but poor Rabbit is so frazzled that he's still babbling about "Nobodies."
* The modern Canmore siblings in ''WesternAnimation/{{Gargoyles}}''. Initially, Jason and Robyn were determined to wipe out the gargoyle species completely, while Jon was only interested in fighting Demona in particular and was even willing to consider allying with the Manhattan Clan against her. By the end of ''Hunter's Moon,'' Jason and Robyn realized that their vendetta against all gargoyles had done more harm than good, but Jon had decided by then that all gargoyles were evil.
* ''WesternAnimation/SouthPark'''s "About Last Night" takes place right after the 2008 presidential election. Barack Obama's supporters are jubilant, believing his win has instantly solved all of their problems and begin to get drunk and party while John [=McCain=]'s supporters are convinced that Obama's win is a sign of the apocalypse and either kill themselves or hide away in shelters. The next day, everything is still the same and society has not changed one bit. The [=McCain=] crowd realizes they overreacted and decides that maybe Obama won't do such a bad job while the Obama supporters, angry to find out they still have responsibilities and they must pay for their drunken actions, complain that Obama lied and wish they voted for [=McCain=].
