History TheUnreveal / WesternAnimation

* ''WesternAnimation/TheOwlHouse'': At the end of "Eclipse Lake", the bond between Hunter and the red cardinal Palisman has gotten strong enough for Hunter to understand the bird's chirps as actual speech, demonstrated with him learning its name. However, its chirping is never translated for the audience, so it isn't until Hollow Mind that the audience is to learn that its name is [[spoiler:Flapjack]][[note]] although prior to that episode, Flapjack's name was revealed and explained in an audio-short released during an art charity stream on March 13th, 2022[[/note]].

* ''WesternAnimation/TheOwlHouse'': At the end of "Eclipse Lake", the bond between Hunter and the red cardinal Palisman has gotten strong enough for Hunter to understand the bird's chirps as actual speech, demonstrated with him learning its name. However, its chirping is never translated for the audience, so it takes seven more episodes for us to learn that its name is [[spoiler:Flapjack]].

* ''WesternAnimation/TheLegendOfKorra'': The very first episode picks up where [[WesternAnimation/AvatarTheLastAirbender the last series]] left off, with Jinora asking Katara "What happened to Zuko's mom?" Katara slowly tells her granddaughter that that's a ''fascinating'' story, and it involves... and then Ikki interrupts. Anyone interested in that story would have to wait another year for [[Comicbook/AvatarTheLastAirbenderTheSearch the comics]] to explain it.

* In the second season of ''WesternAnimation/TheVentureBrothers'', a large chunk of episode was devoted to three theories on the origins of character The Phantom Limb, while also explaining how Master Billy Quizboy's hand was removed and replaced with a robotic substitute. Though both answers would not be revealed until the third season, at the end of the episode Dr. Venture absent-mindedly enquires how Quizboy got his robotic arm, to which he replies: "Interesting question!... I have no idea."
** To be precise, [[spoiler:Monarch]]'s story was the closest; he got most of the salient facts right (which makes sense, as he's part of the same organization as Phantom Limb and has met him many times), although he wasn't there so it played out differently than he imagined.

-->'''Timmy''': What's ''your'' first name?
-->'''Timmy's Dad''': [[KnowWhenToFoldEm Ooh, I see your point!]]

%%* ''WesternAnimation/TheFairlyOddParents'': Used frequently so as not to reveal Timmy's parents' names.

* The short lived ''WesternAnimation/{{Big Guy and Rusty|TheBoyRobot}}'' program from FOX in the late 90's featured a monkey which rode around on the boss' shoulders who could talk, think, and reason better than he could. None of the characters in the show seemed to think it was unusual, except for one monster of the week villain who questioned her on the origins of her abilities. As she began to explain ("Well, it all started when I was a wee, little monkey...") the titular robots burst in, and she ends the discussion ("Ah, some other time.").

** Occurs again regarding The Monarch's motive for [[ArchEnemy terrorizing the Ventures for years]], as he spent the entirety of the series refusing to elaborate ''why''. As it turns out, [[spoiler:there was never any one reason he hated Rusty; it was just a series of [[EvilIsPetty petty reasons for disliking him]] that were amplified by the baboon DNA [[CloningBlues Jonas Venture used to create him]] making him hyper-aggressive]].

** This is played rather tragically in the case of the Sovereign's true identity in "All This and Gargantua-2." An earlier episode revealed that, despite assuming Creator/DavidBowie's appearance and mannerisms, he wasn't actually David Bowie. Then, when he appears in the episode, he assumes the form of the apparently long-dead Jonas Venture, which would be a suitably dramatic reveal... but Dr. Mrs. The Monarch immediately realizes he's just messing with her, and demands to know who he ''really'' is. He takes a few seconds to respond, and then says "Just some bloke who wanted to be anyone but himself." Shortly afterward, he is killed by a misfiring gun while attempting to flee his compound.

** "Operation: R.A.I.N.B.O.W.S.": Numbuh Three freaks like heck over Mr. Mogul's whispered big plan for the Rainbow Monkeys he's just captured. Later, Mr. Mogul and other adults are amongst themselves, but come time to mention his big plan, he still whispers it anyway.

** "Operation: R.A.I.N.B.O.W.S.": Numbuh Three freaks like heck over Boss's whispered big plan for the Rainbow Monkeys he's just captured. Later, Boss and other adults are amongst themselves, but come time to mention his big plan, he still whispers it anyway.
** Numbuh Three and Numbuh Four's relationship is obvious to the viewers and the characters, and even themselves, but whenever they confess their feelings, they're blocked off. For example, Numbuh Three is playing Truth-or-Dare at a slumber party and two girls ask her if she likes-likes Numbuh Four, and before she can, they're cut off.

** In another episode, Timmy has been traveling through his summer reading list (instead of reading the books) and Sherlock Holmes gets pulled into reality at one point and quickly forgotten. At the end of the episode, he's at the Turner home, impressing the parents with his deduction skills. "And I have deduced your real names are-" cut to black, end title card, then Timmy's dad announces "That's amazing!" or something to that effect.

** In "A Pal For Gary", it is not made clear what species Puffy Fluffy is; although, most sources say he is a breed of nudibranch.

** In ''Phineas & Ferb Franchise/StarWars'', Candace is the boys' LongLostRelative. She asks what happened to her and Phineas' biological father, but his answer is cut off by [[EarthShatteringKaboom the Death Star exploding]] (with them still on it).

* Miss Sara Bellum from ''WesternAnimation/ThePowerpuffGirls''. Her face is usually just offscreen, but it's been hidden by numerous things including clipboards, bandages, shadows, flying debris, even pickles. Heck, in one of the books, the thing obstructing her face was ''Bubbles''! Her face was [[http://t1.gstatic.com/images?q=tbn:zsv5J6kEREvboM:http://newsimg.ngfiles.com/110000/110737_bellum_face.JPG&t=1 revealed for one frame]] in the 10-year-anniversary episode.

* ''WesternAnimation/SheRaAndThePrincessesOfPower'': When the show ends, a number of minor questions remain unanswered, including [[spoiler:Catra's species (not a single other cat girl or boy appears), why Entrapta's hair is prehensile, where Adora's biological family is, what became of the First Ones, what happens to Horde Prime's clone army after his death, or whether Angella will ever escape from being trapped between dimensions. It also leaves a lot of Horde Prime's backstory vague, though judging from some of his dialogue it must have been awful.]]

* ''WesternAnimation/TheLegendOfKorra'':
** The very first episode picks up where [[WesternAnimation/AvatarTheLastAirbender the last series]] left off, with Jinora asking Katara "What happened to Zuko's mom?" Katara slowly tells her granddaughter that that's a ''fascinating'' story, and it involves... and then Ikki interrupts. Anyone interested in that story would have to wait another year for [[Comicbook/AvatarTheLastAirbenderTheSearch the comics]] to explain it.
** We never really find out why Korra could [[spoiler: suddenly use airbending when Amon robbed her of her other bending gifts]]. WordOfGod is that [[spoiler: Amon couldn't sever her connection to airbending]] because it wasn't fully established yet, and she could suddenly use it because she was [[spoiler: selflessly defending Mako, as opposed to her usual motivation, which is at least partly driven by her own gratification]].

* In ''WesternAnimation/GodTheDevilAndBob'', Bob asks God various awkward questions about morality and the nature of the universe. God replies "Look, you're not supposed to find this out until after you die, but..." at which point a train goes by and drowns out God's voice. The audience only gets to see the hand gestures God makes during his explanation and the only thing we hear at the very end is "like a cork trapped in a whirlpool". Bob seems amazed and says it makes perfect sense when explained that way.

* Throughout ''WesternAnimation/KimPossible'', no explanation was ever given about why Dr. Drakken's [[AmazingTechnicolorPopulation skin is blue]]. Flashbacks show that it wasn't always that way, and when all of Drakken's evilness got transferred into Ron, Ron gradually turned blue while the now-good Drakken gradually went back to his original skin colour. In TheTag at the end of the GrandFinale, Professor Dementor asks him how his skin turned blue. He starts to tell the story, only for [[UpToEleven the entire show to end]] before we hear any real details.

* ''WesternAnimation/TeenTitans'':

** In "Tea At The Treedome", we never find out how or why Sandy is living at the bottom of the ocean[[note]] [[WordOfGod Word Of God]] simply states that it's [[ForScience For Science!]] [[/note]], because [=SpongeBob=] runs off to get some water from the bird bath just as she starts to explain.

** In the Spongebob movie, Plankton finally gets his hands on the secret recipe of the Krabby Patties, but we're never told what it is, we just see him selling them at the Chum Bucket.
