History Main / AdaptationalExplanation

* ''Franchise/PowerRangers'':
** ''[[Series/PowerRangersOperationOverdrive Operation Overdrive]]'': in [[Series/GoGoSentaiBoukenger Boukenger]], Gaja's {{Mooks}}, the Karths ("Chillers" in ''OO'') are often seen being used by other villain factions without explanation. The ''OO'' episode "Just Like Me", which features one such battle from the Sentai version, has Flurious' flunky Norg bring "Chiller stones" to Moltor, which he uses in the fight against the Rangers.
** The first episode of ''Series/MiraiSentaiTimeranger'' has a bad UnexplainedRecovery moment when the Timerangers are trapped in a crashed ship which explodes with them on it... and are inexplicably uninjured afterward. In ''Series/PowerRangersTimeForce'', Trip frees himself and gets the others off the ship before it blows.

* ''Franchise/StarWars: VideoGame/TheForceUnleashed'' novel by Creator/SeanWilliams not just expanded what we saw and played in the game, also gives TheProtagonist (The Apprentice, codenamed Starkiller) a proper name and a background: Galen Marek, son of the late Jedi knight Kento Marek (unnamed in the games and killed in the first episode). His mother is briefly mentioned, but in the novel as well in ''TFU II'' got a name and a background too (Mallie Marek, also a Jedi Knight who died when Galek was just a baby).

** Bridgette's feelings for Alejandro are explained to be the result of Alejandro raping her during the flight to Egypt, which causes her to develop StockholmSyndrome (rather than simply just Bridgette being unable to control her hormones as the show implied).
** Bridgette's apology song is explained here as being written by Trent to help her with winning Geoff's heart back, since he and Justin both believe she would never have willingly cheated on Geoff and thus side with Bridgette when Geoff breaks up with her.
** Noah's ShipTease moment with Bridgette in the Yukon is explained here to actually be him intent on getting closer to Bridgette in an attempt to warn her to stay away from Alejandro for her own good. However, the author speculates that Noah still actually has a crush on Bridgette.
** Ezekiel's feralization is explained here as the result of him getting a brain injury while hiding in the cargo hold when the plane crashed in Jamaica, causing him to lose the ability to speak properly and most of his higher mental functions.
** Beth's inability to answer the question about Duncan in Aftermath Aftermayhem is explained here to be intentional on her part (since ''Action'' established that she knows everything about her fellow contestants) as part of the Peanut Gallery's gambit to get rid of Blaineley.
** We also see how the contestants survived the volcano's eruption in the finale of ''World Tour''; [[spoiler:they were all rescued by the interns and taken home to Canada safely (except Alejandro, who is left for dead by everyone).]]

** ''Fanfic/PredatorAndPrey''
*** Bridgette's feelings for Alejandro are explained to be the result of Alejandro raping her during the flight to Egypt and causing her to develop StockholmSyndrome.
*** Noah's unusually affectionate hug towards Bridgette is explained here to actually be him intent on getting closer to Bridgette in an attempt to warn her to stay away from Alejandro.
*** Ezekiel's feralization is explained here as the result of him getting a brain injury when the plane crashed in Jamaica, causing him to lose the ability to speak properly and most of his higher mental functions.

* ''Fanfic/TotalDramaAllStarsRewrite'': Owen and Noah's reasons for continuing to star on reality TV (as mentioned in ''The Ridonculous Race'') are explained here as the result of Chris making them do so in exchange for giving them more money to [[spoiler:help Noah fund Dawn's animal shelter]].

* The two-hour episode "The Way of the Warrior" in ''Series/StarTrekDeepSpaceNine'' had a minor subplot where Drex and some other Klingons assault Garak on the station and a second one where after the Klingons threaten to open fire on Deep Space Nine they dismiss Sisko's threats as "thoron fields and duranium shadows". The novelization of the episode ties these two together -- Drex was assigned by Martok to get intel on [=DS9=]'s defenses, and Garak figured it out. Garak then ''provoked'' Drex and his thugs to beat him up by making them think he had the information. Only Garak had dummied up a fake report by a "Chief [[NiceHat Tam O'Shanter]]" saying that [=DS9=] [[FakeWeakness had minimal weapons and any scans would show false readings]].

* In an early episode of ''Series/MaskedRider'', a trio of skull-faced monsters are pointed out to have a weakness to water, and Masked Rider is able to destroy them by tackling them into a lake. This weakness is not mentioned in ''Series/KamenRiderBlackRX'', where going in the lake just makes them explode for no apparent reason.

* The [[Literature/DoctorWhoNovelisations novelizations]] of the first ''Series/DoctorWho'' stories from Classic Who added various details to the episodes and even expanded a little more the details that were unexplained, usually written by the same scriptwriters of the series. This helped in actual years to get better help to recreate the {{Missing Episode}}s with modern technology, as well using the audiobooks of the time.

* ''Anime/AceAttorney'': This happens in both "Reunion" and "Turnabout". In the case, Phoenix's friend, Maya, who is a spirit medium, is accused of murdering her client while being possessed by a spirit she was supposed to channel. Turns out [[spoiler:the girl she was supposed to channel, Mimi Miney, was actually alive and killed the client to keep it a secret, while Maya's [[EvilAunt aunt Morgan]], whose help was necessary to pull this off, wanted Maya framed to get the position of the master of their clan.]] This, however, leads to FridgeLogic: [[spoiler:While Mimi had much to lose if it was found out she was alive, it wasn't as much as a sentence for murder, and if she didn't know what kind of person Morgan was, how did she know she wouldn't turn her over to the police the moment she asked her for help with the murder?]] The anime version of events explains this: [[spoiler:She didn't. Mimi's plan was to bribe Morgan into faking the channeling and it was ''Morgan'' who made Mimi into an accomplice by threatening to reveal the fact that Mimi was alive. Since Morgan knew that Mimi was desperate to keep it a secret, she knew Mimi would comply]].

** Interestingly, the live-action adaptation itself has this trope occur, too. Here, the Beast's library contains a magical PortalBook that allows the reader to travel to any location just by thinking about it. The Beast explains that the Enchantress left it as a "cruel trick"--even though he could technically leave at any time, he would still look like a hideous monster and be shunned wherever he goes. That's all well and good...until Belle discovers that Maurice is ill and the Beast decides to allow her to leave the castle to go to him, which is proof that he loves her. Unfortunately, the presence of the Portal Book leaves audiences wondering why Belle simply didn't use it to warp to Maurice instantly, then travel back to the castle with him. That question is answered in another adaptation: ''The Beast's Tale'', the [[AllThereInTheManual official manga]], which explains that only the Beast can make the book's magic work, meaning he would have to travel with Belle directly into her village to rescue Maurice, which would likely lead to all three being attacked or even killed.

* In the book ''Literature/ADogOfFlanders'', the windmill catches on fire, but there is no explanation given as to how it came about. In the 1975 TV series/1997 movie, the windmill catches fire because Hans forgot to oil the gears, leading to parts of it getting overheated. In the 1992 anime, someone accidentally drops their cigarette while inside, not realizing it needed to be put out. Regardless of how it happened, Nello is still accused of setting the windmill on fire because Alois' father doesn't want a poor boy hanging around his daughter.

* ''Film/BeautyAndTheBeast2017'' explains why Belle and her neighbors know nothing about the castle in the nearby woods or about the Prince-turned-Beast: the Enchantress's spell has erased all memory of the castle and everyone who lives there from the outside world. The original fairy-tale has a different explanation (the Prince's family ruled a different land and the enchanted castle wasn't his own, but just his temporary home for the duration of the spell), but in [[Disney/BeautyAndTheBeast Disney's animated version]] this is a PlotHole, which the live-action version fills.

** ''[[Series/PowerRangersOperationOverdrive Operation Overdrive]]'': in [[Series/GoGoSentaiBoukenger Boukenger]], Gaja's {{Mooks}}, the Karths ("Chillers" in [=OO=]) are often seen being used by other villain factions without explanation.

* ''Film/Fahrenheit451": In the movie, Montag explains to Clarisse that firemen wear a helmet with the number "451" because Fahrenheit 451 is the temperature at which book paper catches fire. This is never explained in the book and is instead said in the book's tagline.

** In the books, students at Hogwarts tend to be referred to according to their houses ("a first-year Gryffindor" or "a third-year Ravenclaw" and so forth), even though the books are meant to be told from Harry's perspective, and Harry isn't in a position to be keeping track of which house each and every student belongs to. In the films, the Hogwarts robes are given color-coded scarves and neckties corresponding to the four houses, meaning anyone can tell which one a student belongs to just by looking at them.[[note]]However, when Harry and Ron are disguised as 2 Slytherins looking for the Slytherin common room, they ask a girl who tartily replies she cannot know where it is as she is a Ravenclaw, and new named characters are often introducing themselves with their houses. So the books don't always treat it as if Harry knew everyone's house and year, and if the books had any discerning marks for houses Harry and Ron would have known not to ask a Ravenclaw about the Slytherin common room.[[/note]]

** ''Film/HarryPotterAndTheChamberOfSecrets'' explains why Harry couldn't use Parseltongue to appease the basilisk when he fought it in the chamber. In the book, he never even tried for no adequately explored reason, but in the film, Riddle immediately dissuades him from doing so by telling him that the basilisk will only obey the Heir of Slytherin.

The opposite of this is AdaptationalExplanationExtrication, where the original work explains the plot point, but the adaptation doesn't.
