History WhatHappenedToTheMouse / Literature

* ''Literature/PeterPan'': In Wendy's personal imaginary world, she owns a wolf pup abandoned by its parents. Naturally, when she gets to Neverland the wolf appears and becomes her constant companion--or so the narration claims, since it never gets mentioned again. Surprisingly, this detail was never referenced or expanded on in any adaptations, even though the [[LighterAndSofter Disney version]] could easily have turned the wolf into a cuddly WoodlandCreature and the [[DarkerAndEdgier 2003 live-action version]] could have thrown it into some fight scenes. (There was at least one set of illustrations (Trina Schart Hyman's) which didn't neglect the wolf and showed it hanging around at Wendy's feet in the "Home Under the Ground" scene.)

* In ''Liberature/TheMovingFinger'', nothing is said about what happens to Megan's two young half-brothers after her mother is murdered and [[spoiler: her stepfather is arrested for the crime]]. This is especially disturbing because she is almost definitely their closest remaining relative.

* In ''Literature/ABrothersPrice'', there is [[spoiler: Balin Brindle]]. He's only a minor character, but some readers would like to know whether he [[spoiler: really [[ParentalIncest "serviced" his mothers]], whether [[RapeIsASpecialKindOfEvil it was consensual]]]] and whether he was able to marry well.

* When the narrator of Creator/EdgarAllanPoe's "The Fall of the House of Usher" arrives to visit his childhood friend, he's greeted by a footman and valet in Roderick Usher's employ. There are no other mentions of household servants in the story, and no hints as to whether or not [[spoiler: any of the staff live in the House and are killed when it suddenly collapses at the end.]]

* In Creator/AnthonyTrollope's ''Barchester Towers'', it's stated repeatedly in the first nine chapters that the new bishop will spend most of the year with his wife in London, leaving the actual running of the diocese to his assistant Mr. Slope. But the bishop and his wife never actually leave. (The reason is that Trollope put the book aside for a year, and when he returned changed his mind about what would happen without bothering to rewrite the first nine chapters.)

* In ''[[Literature/{{Divergent}} Allegiant]]'', [[spoiler:after the peace treaty is formed, Marcus leaves Chicago and no one knows what happens to him]].

* Marcie, a girl in the first ''Literature/OrigamiYoda'' book, is mentioned once and never again in the entire series.

* In ''Literature/CodexAlera'', [[BigGood First Lord Gaius Sextus]] is married to a woman named Caria, who is actually the lover and co-conspirator of Sextus's rival, Aquitainus Attis. She barely appears in the series, and her last appearance is near the end of book five, when it's revealed that she was poisoning Sextus and had been for years. She then vanishes from the story and is never mentioned again. [[spoiler: WordOfGod ended up confirming that she died when Alera Imperia blew up]].

** In ''The Angel Experiment'', the main characters (who are winged humans, part bird, part human, created by some MadScientists) have gone years without seeing another genetic experiment like them. When they get to a secret facility in New York, they find several experiments caged up. Naturally, they set them free. You'd think they'd want to talk to them or interact with them, maybe help them find a safe place, but it never goes anywhere. Over 5 books later, said experiments don't even get a passing mention, they're never thought of again, so it's a plot thread that went nowhere and contributed nothing to the story.

** ''Literature/MaximumRide'' suffers from this a ''lot''. The second book also has the group finding two kids in the woods. While Angel reads their minds enough to know that they aren't experiments, she can tell that they aren't normal kids. The kids use a tracking device to lead people from Itex to the group, and the most that's found out is that they were kidnapped solely for that purpose, and that they would be left to be eaten by something if they failed. The group leaves them in the woods to be recaptured by the company, and they're never thought of again.
** The third book has an entire facility full of successful experiments, including clones of Max (introduced in the book prior and herself having fallen into this trope until that point), Nudge, and Angel. It's never revealed what happened to the experiments after the facility is captured, and again the group never thinks anything of it.
** Also in the third book, Fang starts a worldwide revolution via the children that read his blog. You'd think that something like that would get a mention in the next book, but it might as well have not happened for all the aftermath there was.

* In ''Literature/ABrothersPrice'', there is [[spoiler: Balin Brindle]]. He's only a minor character, but some readers would like to know whether he [[spoiler: really [[Parental Incest "serviced" his mothers]], whether it was consensual,]], and whether he was able to marry well.

* Early in ''Literature/SixteenThirtyTwo'', a young woman runs into Grantville pursued by soldier who want to rape he. The uptimers kill the soldiers, but one of them is wounded in the process and once he's stabilized the girl is long gone. She doesn't appear again in the novel, but thanks to the opening of the universe to many authors, there is a short story on the subject in the first ''Grantville Gazette''.

* ''Literature/TheFaultInOurStars'' by John Green:

** Ironically, the same thing happened to John Green by readers of the actual novel, even after explaining in an author’s note in the novel and several times [[http://onlyifyoufinishedtfios.tumblr.com/ on this blog]] that he doesn’t know anything more about the plot or characters than that which is contained in the book. Effectively, he knows exactly no more and no less than his readers. Even when they don't believe him.

* In ''[[Literature/WizBiz Wizard's Bane]]'' by Rick Cook an Earth programmer TrappedInAnotherWorld creates a compiler to write spells like computer programs. This allows any human to cast spells to protect themselves from magic creatures, and even should allow many to write their own spells. But locals lack the proper mindset for programming, and by the start of ''Wizardry Compiled'' there's only one case of a local genius improving Sparrow's program. Besides, that patch creates half of the novel's problems. The patch creator is never mentioned again. Somebody that good would eventually join or challenge Sparrow. Maybe he or her was in one of the villages that disappeared without a trace when immortals retaliated.

* Early in SixteenThirtyTwo, a young woman runs into Grantville pursued by soldier who want to rape he. The uptimers kill the soldiers, but one of them is wounded in the process and once he's stabilized the girl is long gone. She doesn't appear again in the novel, but thanks to the opening of the universe to many authors, there is a short story on the subject.

She then vanishes from the story and is never mentioned again. [[spoiler: WordOfGod ended up confirming that she died when Alera Imperia blew up]].

* In the Literature/BookOfJob from Literature/TheBible, Satan shows up for the first few chapters to make a bet with God about Job's faithfulness and then just walks off while the rest of the book focuses on Job dealing with God and his three friends.
