* The penultimate episode of ''WesternAnimation/CodenameKidsNextDoor'' reveals that Chad was a FakeDefector sabotaging the teenagers from the inside. This is in spite of the show containing several scenes of Chad reveling in his villainy when none of the K.N.S or teenagers were around.

* From the infamous ''ComicBook/SpiderMan'' Clone Saga: Multiple:

* ''Series/{{Arrow}}''. After TheReveal that Emiko Adachi was EvilAllAlong, the audience is left to wonder if Emiko visiting her father's grave and TalkingToTheDead was just an act for when her half-brother Oliver Queen tracked her down, or because her desire to be acknowledged by her father [[DaddyIssues had never really gone away]].

* In ''VideoGame/FireEmblemThreeHouses'', Flayn and Seteth pretend to be siblings rather than father and daughter to conceal the fact that they are [[ReallySevenHundredYearsOld actually Saint Cichol and Saint Cethleann.]] They keep this façade even when no-one else is around until their last support conversation when Flayn calls Seteth "father" and [[LampshadedTrope points out]] no one is around to hear them anyway. If you complete their Paralogue, they will [[SecretKeeper tell Byleth about their relationship]], but not their true identities. They also drop the act if you end up killing them on the Crimson Flower route, with Flayn calling Seteth "father" In her dying moments, or if you kill Seteth first. This is a [[JustifiedTrope justified example]] because all of their conversations take place within Garreg Mach monastery where Seteth fears being overheard.

* A {{Justified|Trope}} example occurs in ''VideoGame/Persona5'', after [[PlayerCharacter Joker]] has seemingly been assassinated by [[SixthRangerTraitor Goro Akechi]] with his death being reported as a suicide. The protagonist's teammates react to the news report with silent shock and horror. It's revealed shortly afterward that they had actually known Akechi was going to betray them and came up with a plan to fake Joker's death and were thus pretending to act shocked when the news broke out even if they were by themselves just in case TheConspiracy Akechi works for was watching them. Some of their reactions may have also been genuine as they wouldn't be able to immediately know if their plan had succeeded and Joker was truly killed.

* ''Webcomic/TheLastDaysOfFoxhound'', a comic starring the QuirkyMiniBossSquad from the first ''VideoGame/MetalGearSolid'', essentially had to do a retcon to turn Ocelot, the series' MagnificentBastard, into this. Early in the comic's run, Ocelot was clueless about [[AncientConspiracy the Patriots]], and while dangerous, was on occasion easily overpowered by his psychic/psycho teammate Mantis. Then ''VideoGame/MetalGearSolid3'' came out during the comic's run and revealed that Ocelot had been working for the Patriots at least since the 1960s. The comic's creator, Chris Doucette, had to change everything into Ocelot pretending that he knew less than he did in order to become TheMole to multiple sides on behalf of the Patriots.

* ''WesternAnimation/AvatarTheLastAirbender'': When Iroh and Zuko are hiding as refugees, Iroh comments he can't find any spark rocks to start a fire to make tea. As a Firebender and in the privacy of his own home, this shouldn't be an issue. He still goes to their neighbors' and borrows a set, rather than bend the fire. [[JustifiedTrope Of course, given that he had suspiciously warm tea at the start of the episode and Zuko berated him for doing such, it could be that Iroh learned his lesson]]. Turns out he was ProperlyParanoid, as Jet was the one who stole the spark rocks, and was watching through the window, hoping to catch Iroh bending fire.

* In ''VideoGame/Persona3'', you can watch various security recordings of the inhabitants of the dorms' daily lives, including some particularly embarrassing moments. In Ikutsuki's recording(who, as S.E.E.S.' advisor, is most likely the one in charge of the dormitory and presumably knows about the cameras), in which he writes up a report about the second Full Moon incident and gets sidetracked thinking up puns, he acts like the goofy, affable PungeonMaster you know him as, rather than a nihilistic madman who wants to bring about the end of the world.

At the time, Haru is with her fiancée Sugimura, who is definitely not a fan of the Thieves, although he's not affiliated with the conspiracy.
