History Main / SecretSecretKeeper

* In ''Manhua/GoddessCreationSystem'' after Xiaxi leaves the Wang Pu house she happens to be picked up by the crown prince, where she goes by a new name. They've met before, but he doesn't recognize her and instead tries to find out who she is: No mere commoner could possibly be as well educated as she is. [[spoiler:Before long, he figures out that she's the servant of the Wang Pu family, but keeps quiet about it and doesn't even tell her he knows.]]

* ''VideoGame/SpiderManIsomniac'':

* In ''VideoGame/SpiderManPS4'', [[spoiler: Aunt May reveals at the very end that she's known Peter was Spider-Man for quite some time by telling him "[[WhamLine I want to see my nephew]]". Unlike the comics she isn't in denial about it and is proud of Peter helping people, and kept it a secret so he wouldn't worry about it (which makes many earlier scenes in the game ''much'' more heartwarming). It's a cold comfort for Peter however, as she's on her deathbed]]. As well, [[spoiler:Otto reveals this during the final boss battle by addressing Peter by name during their fight. This sends Peter over the edge and crushes all hope he had in his former mentor]]. A third example (and one that isn't heartbreaking) is revealed in the "Hidden Backpack" side quest, [[spoiler:when Peter finds the backpack holding Matt Murdock's business card, who gave it to Spider-Man one day in case he ever needed a lawyer. Peter is perplexed at how a blind guy knew who he was.]]

* ''WesternAnimation/DcSuperheroGirls'': The episode "[=#BreakingNews=]" has Lois Lane set out to discover the identities of the titular hero team, and within the span of a scene transition, she's essentially figured them out already. Jess (aka Green Lantern) tips the rest of the girls off, so they do their best to put her off the trail, only for their BadBadActing to serve as confirmation. However, Lois decides not to submit her story to the news after dwelling on the matter and realizing the harm it could cause them, keeping her knowledge to herself. Of course, she doesn't tell our heroines this, so they end the episode believing that she didn't run the story because they successfully tricked her.

-->'''James Gordon:''' Wouldn't be much of a cop if I hadn't been able to figure that one out, would I? My ''oldest friend'' is ''gunned down'' by a robber...and nineteen years later, just about the time his ''son'' comes into his ''inheritance''...the Batman makes his first appearance in Gotham City.

** In ''ComicBook/SuperiorSpiderMan'', Max tells Otto that he's received an anonymous email containing proof that "Professor Elliot Tolliver" was Doctor Octopus, but that he'd figured out ages ago that "Tolliver" was San Francisco's Spider-Man and used a surreptitious DNA test to discover that he was really Otto Octavius, but as a strong believer in second chances had kept quiet to see whether Otto earned one (he did).

** In ''ComicBook/MarvelAdventures Spider-Man'', Emma Frost and one of her friends find out that Peter's Spider-Man due to Emma's psychic powers. She later decides not to blab once they find out that the reason Peter's Spider-Man is because of his tragic past.

* In ''[[Fanfic/AfterTheFallMiraculousLadybug After the Fall]]'', an AlternateUniverse where [[ForWantOfANail Weredad exposed Chat Noir's secret identity to Papillion]], Adrien eventually becomes this to [[spoiler:all of the other Miraculi holders]].

* In ''WesternAnimation/{{Encanto}}'', Dolores (who's gift is SuperHearing) reveals at the end of the film during "All Of You" that she had been aware all along that [[spoiler:Bruno still lived in the Casita after his disappearance, hiding in the walls.]] This revelation got subtle foreshadowing beforehand, most notably in "We Don't Talk About Bruno".

* ''Film/StarDust'': The ''entire crew'' knew:

* PlayedWith in ''WesternAnimation/YoungJustice2010''. Instead of a civilian keeping the superhero's secret, Robin knows Artemis' civilian identity (specifically, that she's [[spoiler:from a family of supervillains]]) but doesn't let her know. He did almost bring it up when she was suspected of being TheMole, however. Also, since she doesn't know ''his'' identity, he {{Troll}}ed her a bit when she transferred to his school.
-->'''Dick Grayson:''' ''[taking a selfie with her in their school uniforms]'' We'll laugh about this someday.\\

* ''WesternAnimation/CinderellaIIIATwistInTime'': Although Anastasia finding Fairy Godmother's wand pushed Lady Tremaine to seek revenge on Cinderella, there is a possibility that she's known about Fairy Godmother's involvement for quite some time, as it may have been the only conclusion Tremaine could draw on how Cinderella was able to attend the ball, and also retain the second glass slipper in the first film.

* ''Literature/TheBeginningAfterTheEnd'': There are quite a few characters who are secretly aware that Arthur is the reincarnated King Grey without him knowing. Most of these are [[OurGodsAreDifferent Asuras]] such as Sylvia, Kezess, Mordain, and Agrona ([[spoiler:the last of whom being [[CreateYourOwnHero the one responsible for his reincarnation]] in the first place]]). Rinia is also aware of his true identity due to being a {{Seer|s}}, having experienced many visions of him before she even met him. In addition, [[spoiler:after being partially freed from the Legacy's control, Tessia becomes aware of Arthur's past life as Grey as she is able to view the Legacy's memories of having lived alongside him, but does not hold it against him for keeping it secret from her]].

* ''Literature/TheBeginningAfterTheEnd'': There are quite a few characters who are secretly aware that Arthur is the reincarnated King Grey without him knowing. Most of these are [[OurGodsAreDifferent Asuras]] such as Sylvia, Kezess, Mordain, and Agrona ([[spoiler:the last of whom being [[CreateYourOwnHero the one responsible for his reincarnation]] in the first place]]). In addition, [[spoiler:after being partially freed from the Legacy's control, Tessia becomes aware of Arthur's past life as Grey as she is able to view the Legacy's memories of having lived alongside him, but does not hold it against him for keeping it secret from her]].

** It's occasionally implied that Robbie Robertson figured out Spider-Man's identity a long time ago. If he acknowledged it, then he would be obligated to tell J. Jonah Jameson that Peter Parker was selling pictures of himself. Robbie vehemently denies that he had known when Peter unmasks in the ComicBook/CivilWar arc.

** The first season finale of ''Series/MsMarvel'' has the gang startled to discover Zoe has known all along about Kamala's powers and kept quiet to return Kamala saving her life in the first episode.

* In ''Film/WhatAGirlWants'', Harry is a lord running for political office when he discovers Daphne, the daughter he never knew of. He had been under the impression Daphne's mother, Libby, had left on her own and never told him about the child. Libby responds that it was Harry's disapproving family that drove her to never tell him about Daphne. In the film's climax, Harry [[spoiler: tells the press that he's turning down office as he wants to be with his daughter. Alistair, the father of Harry's fiancee, is outraged and during an argument, reveals that he knew all along Libby was pregnant and kept it quiet so Harry wouldn't "throw his life away for her." Outraged that he was denied the chance to be a good father, Harry punches Alistair in the face and dumps his fiancee (who was also working to keep Daphne away) before flying to America.]]

** Molly Carpenter, Harry's apprentice, unwillingly becomes [[spoiler: Winter Lady of the Fae]] at the end of ''Literature/ColdDays'', an event she and Harry spend several books concealing from her highly religious parents. At the end of ''Literature/BattleGround'', her father Michael quite casually reveals that they'd figured it out some time ago, and don't have a problem with it or hold it against Harry that it happened to her on his watch.

* In ''[[https://www.fanfiction.net/s/1857017/1/The-New-Teacher The New Teacher]]'', [[Franchise/SpiderMan Peter Parker]] starts working as a teacher at [[Franchise/XMen the Xavier Institute]] and until chapter 40 (after Peter is forced to use his powers during the Brotherhood’s latest attack on the school), only a few X-Men know that he’s Spider-Man, to the extent that they even keep that knowledge from the rest of the team. Wolverine knew Peter's identity from the beginning, Shadowcat learns when she walks in on Peter changing out of his costume after Spider-Man helped stop a riot at the school, Rogue suddenly recalls some of the personal information she absorbed from Spider-Man in ''ComicBook/ContestOfChampionsII'' after spending time with Peter, and Wind Dancer’s awareness of wind allowed her to overhear the Green Goblin refer to Spider-Man by name when the Sinister Six take some of the students hostage.

* ''Film/TheAmazingSpiderMan'' implied that Aunt May knew Peter was Spider-Man but didn't tell him. By the time of ''Film/TheAmazingSpiderMan2'', it's pretty obvious that she knows, though he doesn't seem to think she does.

* ''[[Film/SpiderMan2 Spider-Man 2]]'':
** It's implied Aunt May realized Peter was Spider-Man after he saved her from Doc Ock during their fight at the bank. She never directly confronts him about it, but later in the film she talks him out of his TenMinuteRetirement, and in the third film she advises him not to seek vengeance against Sandman, claiming that "Spider-Man" doesn't kill people.

** Post-''Flashpoint'', it was revealed that Joe Chill knows that Bryce Wayne is Batman. Remorseful over what he did to the Waynes, Chill never told anyone and spent most of his free time penning a letter of apology to Bruce (he's illiterate). After Bruce learns that he knows, Bruce saves Chill’s life and stays by his side as he passes away from illness.

** Mary Jane Watson. During Tom [=DeFalco=]'s initial run on the book, it was revealed in ''Amazing Spider-Man #257'' that Mary Jane knew Peter's secret for years. ''Parallel Lives'' reveals she's known since pretty much the beginning, having seen Peter leave his bedroom window as Spider-Man on the night of Uncle Ben's death.

** Aunt May is eventually revealed to have known for years, though she was in denial. Aunt May let Peter know the truth shortly before she died during ComicBook/TheCloneSaga ([[WhamLine "Peter, what is it like to fly?"]]). Then it turned out that was a [[RetCon "genetically-altered actress"... ]]
** It's occasionally implied that Robbie Robertson figured out Spider-Man's identity a long time ago. If he acknowledged it, then he would be obligated to tell J. Jonah Jameson that Peter Parker was selling pictures of himself. Robbie vehemently denies that he had known when Peter unmasks in the Comicbook/CivilWar arc.

* ''Fanfic/SOE2LoneHeirOfKrypton'': During the Parasite arc [[spoiler:both Rei Ayanami ''and'' Misato Katsuragi]] figured out Asuka was Comicbook/{{Supergirl}}. [[spoiler:Misato]] because the Parasite barged into his apartment demanding to know where Asuka was and later he was defeated and fought by Supergirl, and [[spoiler:Rei]] because she fought the Parasite alongside Supergirl and noticed their similar appearances.

* In ''Manga/SpyXFamily'', due to her telepathy, Anya is the only one who knows Loid is a spy and [[Characters/SpyXFamilyYorForger Yor]] a hitwoman. She keeps quiet because of her own instructions to keep her powers secret. Fortunately, she thinks having a spy and assassin as her parents is awesome.

** Daredevil learns Spider-Man's secret identity when he meets Peter for the first time in ''ComicBook/TheDeathOfJeanDeWolff'', since he recognizes Peter's heartbeat (and Aunt May used a FullNameUltimatum, so Matt learned his name too). He only reveals this to Spider-Man in order to stop the enraged superhero from murdering the guy who killed Jean [=DeWolff=].

* In ''VideoGame/SpiderManPS4'', [[spoiler: Aunt May reveals at the very end that she's known Peter was Spider-Man for quite some time by telling him "[[WhamLine I want to see my nephew]]". Unlike the comics she isn't in denial about it and is proud of Peter helping people, and kept it a secret so he wouldn't worry about it (which makes many earlier scenes in the game ''much'' more heartwarming). It's a cold comfort for Peter however, as she's on her deathbed]]. As well, [[spoiler:Otto reveals this during the final boss battle by addressing Peter by name during their fight. This sends Peter over the edge and crushes all hope he had in his former mentor]].

'''Mr. Hawkins:''' You can drop the act, Virgil.\\

'''Mr. Hawkins:''' Wasn't hard to figure out. Why else kidnap me to get to Static? And maybe, maybe in the back of my mind, I've always known.

* Virgil's dad in ''WesternAnimation/StaticShock'' only consciously invokes the trope in the interim between his capture by the villains and his first conversation with Static, as it's then that he reveals that he knows the truth. (There aren't many reasons to kidnap a middle-aged counselor and sometimes community leader.) Cue the page quote.

* ''Fanfic/ForTheGloryOfIrk'': It turns out that [[spoiler:Professor Membrane and his wife Moira]] have known the truth about Zim being an alien all along, due to his old PaperThinDisguise. However, they acknowledged he wasn't really a threat, and therefore not only left him alone but sought to talk Dib out of his obsessive pursuit of him before he ruined himself with it.
* ''Fanfic/TheirBond'': The fact that Queen Zelda was sexually abused by Ganondorf for several years is supposed to be a closely guarded secret of Zelda and Link's. When her court puts Zelda on trial for treason after finding a deceased soldier's account of the abuse in his diary, Zelda realizes that her "secret" is not so secret after all. In fact, ''at least'' ten people, including of Zelda's closest companions and several guards, know of it. Everyone just keeps mum about it.
* In "[[https://archiveofourown.org/works/36162718/ The Devil and His Urchin]]", Azrael is aware that Trixie Espinoza is Lucifer's daughter before even Lucifer himself, as God had her keep an eye on Trixie to hide her from the attention of the Silver City, to the extent that she was forbidden to even tell Lucifer about Trixie's existence until he found out about her on his own.
* In "[[https://www.fanfiction.net/s/1857017/1/The-New-Teacher The New Teacher]]", [[Franchise/SpiderMan Peter Parker]] starts working as a teacher at [[Franchise/XMen the Xavier Institute]] and until chapter 40 (after Peter is forced to use his powers during the Brotherhood’s latest attack on the school), only a few X-Men know that he’s Spider-Man, to the extent that they even keep that knowledge from the rest of the team. Wolverine knew Peter's identity from the beginning, Shadowcat learns when she walks in on Peter changing out of his costume after Spider-Man helped stop a riot at the school, Rogue suddenly recalls some of the personal information she absorbed from Spider-Man in ''ComicBook/ContestOfChampionsII'' after spending time with Peter, and Wind Dancer’s awareness of wind allowed her to overhear the Green Goblin refer to Spider-Man by name when the Sinister Six take some of the students hostage.
* In ''[[Fanfic/AfterTheFallMiraculousLadybug After the Fall]]'', an AlternateUniverse where [[ForWantOfANail Weredad exposed Chat Noir's secret identity to Papillion]], Adrien eventually becomes this to [[spoiler:all of the other Miraculi holders]].
* Happens several times in ''Fanfic/BackToUs''. [[spoiler:Alya]] figures out [[spoiler:Nino and Marinette]]'s identities due to SomethingOnlyTheyWouldSay, and it is revealed that [[spoiler:Felix]] has known [[spoiler:Adrien and Camille]]'s identities all along and that [[spoiler:Gabriel Agreste and Daniel Trace]] knew [[spoiler:Adrien]]'s identity all along. All of them decide to keep quiet for various personal reasons.
* ''Fanfic/DodgedABeetle'' has Marinette secretly pass the Earrings to [[RoleSwapAU her new friend Lila]] shortly after her disastrous debut against Stoneheart. While Lila is unaware that her new friend was the former Ladybug, Tikki naturally knows, and makes clear to Marinette that she considers her to be a potential liability.
* ''[[https://www.fanfiction.net/s/13231242/1/A-Frozen-Supervillain A Frozen Supervillain]]'': Plagg senses Nooroo's presence enough times to deduce that Gabriel is Hawk Moth; however, he's unable to tell Adrien the AwfulTruth. So he sabotages the heating system in order to render Gabriel absolutely ''miserable'' while inside his lair, an action that ends up nearly killing the supervillain.
* ''Fanfic/HeroChat'': Chloé deduced everyone's identities pretty quickly (she figured out Adrien because he's her childhood friend, Marinette didn't take much more effort, and once you've figured her out then the other heroes are just a case of matching them to the rather small category of "people who Marinette trusts enough to give a Miraculous"). She tells Alix because she needs someone to talk to about how ''unbelievably stupid everyone else is''. There's a {{Glamour}} that keeps people from making the most obvious connections, but even considering that, everyone is ''really'' bad at hiding their identities from each other. For example: Adrien and Chat Noir are both rich, blond, with emotionally distant fathers and a mother who disappeared about a year ago. No one notices, even when directly comparing them. At several points, Chloé runs interference by giving (false) excuses for why all the heroes have suspiciously similar experiences, but eventually she gives up and convinces Ladybug to let her do an identity reveal. Ladybug agrees only on the condition that someone figures out everyone's identities... unaware, of course, that Chloé already figured them all out months ago.
* ''Fanfic/JulekaVsTheForcesOfTheUniverse'' opens with Juleka accidentally witnessing Ladybug detransforming. The next day, she witnesses Adrien ''transforming''. Later chapters have her learning other secret identities, either through further accidents or by putting the pieces together.
* PlayedWith in ''[[https://salthaven.tumblr.com/post/190458693897/ A Lady's Scout (and the Salt within her Soul)]]''. As part of a plan to [[LiarRevealed expose Lila]] while punishing her [[FairWeatherFriend Fair-Weather Friends]] [[AccusationFic for abandoning her]], Marinette gives the former temporary heroes gifts implying that she knows their secret identities. These double as 'parting gifts' signaling that the recipient won't be becoming that hero again. Everyone remains unaware that she's Ladybug, but grow convinced that she's been secretly working as a 'talent scout' for the superheroine.
* ''Fanfic/PowersOfInvisibility'' puts Juleka in this role, after she sees Marinette and Adrien transforming during the Evillustrator attack in Chapter 5, with it stating that she was already 90% sure it was them anyway. The following few chapters have numerous moments where Juleka privately snarks about just how bad the two's inexplicably successful attempts to hide their identities are, including from each other. She becomes a regular Secret Keeper to Adrien in Chapter 11, and to Marinette in Chapter 15, and both times Juleka is greatly amused to tell them she figured them out months ago. On a side note, the two of them don't actually connect the dots regarding each other until Juleka forces the issue in Chapter 23, despite knowing about their mutual friendship with her.
* After Miss Bustier in ''[[https://archiveofourown.org/works/24205963/chapters/58796419 Reevaluate]]'' and ''[[https://archiveofourown.org/works/24205963/chapters/65529913 Reassessment]]'' accidentally discovers that Marinette and Adrien are Ladybug and Chat Noir, she decides to discretely help them out, such as keeping Lila away from them and giving them both assignments that act as the perfect alibi in order to transform and fight during akuma attacks.
* In ''Fanfic/TheSameMoonShines'', Lan Qiren figured out that Tang Lijuan followed Lan Wangji to Lotus Pier when she up and vanished shortly before Lan Wangji joined the Jiang Sect. He never told anyone, content to allow his sister-in-law live freely with his nephew.
* In ''Fanfic/TheSevenMisfortunesOfLadyFortune'', Madame Zhou states that she knew Marinette's identity since the day she was rescued, because she was wearing her costume at the time.
* In ''[[https://archiveofourown.org/works/13236141/chapters/30276501 Teaching Lessons]]'', Gabriel Agreste figured out that Adrien was Chat Noir the instant he saw his ring, but has kept quiet to avoid alienating him and taking away something he truly enjoys. He internally snarks about how obvious Adrien is to anyone who knows what to look for and gives him subtle advice towards wooing Ladybug. [[spoiler:Once Adrien brings Marinette home for a date, Gabriel instantly recognizes her earrings and deduces she is Ladybug and that they unmasked to each other offscreen.]]
* PlayedForHorror in ''[[https://archiveofourown.org/works/33994849/chapters/84549145 Watch Me Burn]]'': Adrien learns that Marinette is Ladybug and, as in [[Recap/MiraculousLadybugS03E22CatBlanc "Cat Blanc"]], hides this from her while starting to date her. He also ramps up his harassment of Ladybug as Chat Noir, purely [[ForTheEvulz for his own amusement]], intending to string her along for as long as possible before revealing the truth.
* ''Fanfic/CrimsonAndEmerald'':
** The fact that [[spoiler:Kiyome]] is a vigilante is known by the Midoriyas, [[spoiler:the Commission]], and [[spoiler:All for One]]. All of them have their own reasons for keeping this secret.
** Melissa is aware that [[spoiler:All Might is her biological father]], but hasn't told her dad that she knows.
* ''Fanfic/DirtyLittleSecrets'': Todoroki knew that [[spoiler:Shinso brainwashed Mineta]].
* ''Fanfic/ThePiecesLieWhereTheyFell'': [[spoiler:Xvital admits that she left her intended husband because his mother had discovered she was a thief, and persuaded her into running off and leaving him before the wedding because he'd hate her if he found out. When Xvital and Tizoc reunite, Tizoc reveals he'd known about her being a thief practically from the beginning and didn't care, he still loved her and wanted to marry her. Then he proposes again, and she says yes.]]
* ''Fanfic/AdviceAndTrust'': Rei figured out that Shinji and Asuka were engaged in a SecretRelationship, but she kept it to herself for a while since she understood their motives to hide it from everyone.
* ''Fanfic/TheChildOfLove'': After getting together Shinji and Asuka spent a while pretending they were still fighting. Misato knew what they were really doing but she pretended she was clueless.
-->'''Asuka''': I...I don't know why I'm telling you all this...you don't know anything...\\
'''Misato''': Do you think I'm blind, Asuka?\\
'''Asuka''': ''[sobbing a little]'' Huh?\\
'''Misato''': Wait a minute here. My two roommates acting like lovers from one month to another... I'd have to be deaf and blind to not notice that. And I saw you two kissing in the car last week, remember? I bet that you forgot about the rear-view mirror. And what about the many times when I surprised you two? You were so embarrassed... and I also know that sometimes you've slept together in your bed. I'm not stupid, you know.
* ''Fanfic/DoingItRightThisTime'': Ritsuko has figured out what Shinji –and maybe Asuka and Rei- are time-travellers but she has kept it to herself.
* Ernie, owner of the first LocalHangout in the series (Morphin' through Zeo), is often portrayed like this. The way all his best customers wear colour-coded outfits and constantly vanish and reappear without explanation, you'd ''hope'' he suspected something... WordOfGod for ''Franchise/PowerRangers'' doesn't state that he actually ''knew'', but of course, it can go either way in fanfic.
* ''Fanfic/PersonalityConflicts'': During ''Final Frontier'', Trevor Park (and possibly Ernie Townsend, who was also there) figure out that Detective Jerome Stone had figured out the identities of the Power Rangers some time back (which he confirms), but none of the Rangers know (yet) that he knows.
* In the fic ''[[https://www.fanfiction.net/s/2299160/1/Shattered Shattered]]'' Ikuko Tsukino becomes this for her daughter upon realizing that Usagi is Sailor Moon.
* In ''Fanfic/EnTempusVeritas'', as in canon, Lana learns Clark’s secret and Lionel is the only one who knows that she knows. However, this version of events takes this twist even further to the point that Clark never learns that Lana knows his secret [[spoiler:before the ‘illusion’ ends and he returns to reality]].
* ''Fanfic/TheresNoRuleThatSaysAWolfCantBeAJedi'': To someone with a wolf's nose, it's quite obvious that Anakin and Padme are married. However, Swift's archaeological research has revealed that Jedi in times past didn't forbid it, with the reasons for the current rules still being under investigation, and he chooses not to say anything. [[spoiler:Until the Jedi Council are going to arrest Senator Palpatine as a Sith, and Swift knows that Anakin really needs to be with his wife right now and ensure her safety.]]
* "[[https://www.fanfiction.net/s/5016353/1/Fair-is-Foul Fair is Foul]]" has Cameron reveal that John's future self actually told her that Kyle Reese is his father, leaving Sarah and Derek disturbed that John gave away his greatest secret to a Terminator even though the John they know hasn't done it himself. John in turn is frustrated that they're judging him for a decision he hasn't made yet even as he argues that this should be proof that Cameron can be trusted.
* ''[[https://archiveofourown.org/works/22803655 What Do You Call a Bug's Parents?]]'' has Tom and Sabine having known their daughter is Marinette for a month ''before'' she tries to sneak to be a hero while sick, at which point they make it clear to her they know and substitute for her until she recovers fully.

* ''Anime/PrettyCure''
** Honoka's grandmother, Sanae, in ''Anime/FutariWaPrettyCure''. It's unclear just how much of the secret she knows, though. She seems to enjoy being mysterious about it.
** ''Anime/HealinGoodPrettyCure'' has the Cures' families and friends discover their identities during the final battle. The girls are exhausted afterwards, so they decide to keep it secret...while thanking them for what they did in their own way.

* ''Fanfic/SOE2LoneHeirOfKrypton'': During the Parasite arc [[spoiler:both Rei Ayanami ''and'' Misato Katsuragi]] figured out Asuka was Comicbook/{{Supergirl}}. [[spoiler:Misato]] because the Parasite barged into his apartment demanding to know where Asuka was and later he was defeated and fought by Supergirl, and [[spoiler:Rei]] because she fought the Parasite alongside Supergirl and noticed their similar appearances.

* In ''Fanfic/BabyWontYouPleaseComeHome'', Moira has taken on this role, as she is to date the only person aware that Malcolm Merlyn is alive and that he is Thea’s father. She is also secretly aware of Oliver’s identity as the Arrow and that he has taken Thea into his confidence.
* In ''Fanfic/TheCuttingEdge'', the time-displaced Laurel of course knows that Oliver is the Hood from the beginning, but he doesn't know that she knows at first. [[spoiler:Batman also deduces the Green Arrow's real identity when he comes to Starling]].
* ''FanFic/RaptureFalls'': Dr. Tenenbaum knew Atlas's secret long before Atlas himself knew he even ''had'' one, due to his memory loss.[[spoiler: Atlas had forgotten that he was an [=ADAM=]-created split personality of Frank Fontaine who pulled a SplitPersonalityTakeover, but Tenenbaum knew Atlas was one of Fontaine's personas (after all, she was the one who helped Jack break free of him) and quickly figured out that Atlas genuinely didn't know of his previous identity.]]
* A FandomSpecificPlot for the series are stories where Ran figures out that Conan is Shinichi without letting him know about it. Examples include ''[[https://www.fanfiction.net/s/10024966/1/The-right-words The right words]]'' and ''[[https://www.fanfiction.net/s/8966375/1/Bittersweet-Deduction Bittersweet Deduction]]''.
* ''Fanfic/ThreePointShot'': The third motive turns everyone who uses the confessional into one, as they become privy to another student's secret, as arranged by Monokuma. [[spoiler:Angie takes her knowledge of Shuichi's secret to the grave with her, though she openly expresses her disgust with him.]]
* ''[[https://www.fanfiction.net/s/6622801/1/Social-Networking Social Networking]]'' has the popular kids discover Danny's secret and [[spoiler:refuse to allow Paulina to use the information as blackmail, as well as coming to a HeelRealization that they have all been terrible to the person they consider a hero]].
* In ''[[https://www.fanfiction.net/s/6514538/1/Subtlety Subtlety]]'', the entire town of Amity Park (barring Danny's parents) know Danny Phantom is Danny Fenton and except for Danny and his friends, and everyone knows that everyone knows. They just let him pretend and act like they don't see him use his powers or transform, even when he does things like turning intangible in the middle of the cafeteria.
* In ''Fanfic/PartOfTheNight'', it's revealed that the other Major Crimes detectives knew all along that Gordon was lying when he claimed Batman killed Harvey Dent. They said nothing because they correctly assumed that Gordon and Batman had come up with that cover story to ensure that Dent's case against the Gotham mafia didn't get thrown out. Stephens ultimately confirmed this was exactly what was going on from talking to Ramirez after Gordon made her resign in disgrace for her role in Rachel's death.
* In ''[[https://www.fanfiction.net/s/10555228/2/Don-t-Poke-the-Golden-Goose Don't Poke The Golden Goose]]'', Jimmy Olsen learns Superman's identity. [[spoiler:Then he discovers that Perry White knows, as do most of the other reporters (except Lois). White insists that everyone take on this role because Clark Kent is a good reporter, having a superhero in town allows for steady news stories, and he respects Clark's need to have a break from crime-fighting.]]
* A somewhat complicated version in ''[[https://www.fanfiction.net/s/11888050/1/Guardian-Angels Guardian Angels]]''. Laurel (as the Black Canary) learns that Oliver is the Hood and Diggle is his partner (which they know), but they don't know that she's the Black Canary. As such, whenever she's the Black Canary she can act like she knows who they are; but as Laurel she has to act as if she doesn't know.
* Several of them in ''Fanfic/KaraOfRokyn'':
** [[ComicBook/{{Supergirl}} Kara]] is certain that Van-Zee and Ak-Var are the heroes Nightwing and Flamebird, but she keeps her suspicions to herself:
--->"Kids," said Van, and both subsided for the moment. Kara studied his jaw for a second. She was pretty sure that he was Nightwing, the Batman of Kandor, and that his friend Ak-Var, who was married to Van's niece, was Flamebird. Both of them had helped bring down the Zoners in her last adventure. But she'd had a secret identity, too, and there was one cardinal rule among super-heroes: don't pry.
** Both Lois and Jimmy figured out Superman's secret identity at some point, but they chose to not let on.
* ''Fanfic/SonGohanTheDestroyer'': By following the gossip among the gods, King Kai realizes that Son Gohan has become Beerus' successor. Knowing that Goku was deeply hurt by the [[FakingTheDeath 'death']] of his son in the Cell Games, he decides not to tell him that Gohan is actually training to become the new God of Destruction, believing that information would only hurt him more.
* ''Fanfic/TheSecretBiographyOfDonaldDuck'': Webby and the triplets learn about all of Donald's secret adventures by reading the titular book. Later, Violet and Lena are brought into the loop, as they all keep mum while trying to figure out the best way to properly confront him about it.
* ''Fanfic/GuidingLightAuroraRose2081'': Dolores knows about Bruno in the walls, and every day she cleans away the handfuls of salt he throws away. This time is even more significant because everyone in Encanto believes him to be Mirabel's kidnapper so she keeping his secret means there's more to Mirabel's disappearance.
* ''Fanfic/TheTwoSeers'': Dolores figures out that her uncle and cousin were living in the walls and ends up becoming a secret provider for the both of them. When Camilo has a run in with Mirabel, Dolores refuses to say anything about it to him.
* Chrom in ''Fanfic/{{Pretender}}'' knows Robin's true origins, [[spoiler:that he's Plegian and Validar's son]], long before Robin himself finds out in the hopes that keeping him out of the loop will help him stay away from the darkness of his past.
* One FandomSpecificPlot is that Crowley and Aziraphale's [[MundaneUtility minor miracles]] get noticed by the humans around them, but they leave them be.
** In ''[[https://archiveofourown.org/works/40719213 A Touch of the Sight]]'', Aziraphale quietly rearranges reality to get fresh chocolate cherry scones right when he wants them. The baker finds herself making an unscheduled batch of chocolate cherry scones using perfect cherries she couldn't find in months, and deduces that [[StevenUlyssesPerhero Mr. Fell]] will come in the second she's done.
** Since Crowley and Aziraphale regularly dine at the Ritz without making reservations beforehand, a few fics (like ''[[https://archiveofourown.org/works/19819165 Code Angel]]'') show that the staff knows when they're coming just by the inexplicable empty table. In ''[[https://archiveofourown.org/works/24944380 A Nightingale Sang in Berkeley Square]]'', since Crowley and Aziraphale sober up by returning the alcohol to the bottles, the kitchen now knows to re-cork the empty bottles, or else they'll find their recycling bin full of wine.
* {{Subverted}} in ''Fanfic/TheRigelBlackChronicles'', where Hermione confronts Harry to tell him that she's known for months that [[spoiler:he's a girl]]. He's both amused by her mistake, and concerned that she dug that far; the truth is that he's [[spoiler:Arcturus Black, and has switched places with his cousin Harriett Potter so that she can attend Hogwarts despite being half-blood and he can attend the American Institute of Magic despite Sirius' objections to sending him overseas]].
* ''Fanfic/ForgedDestiny'': At the end of Book Six, Chapter 5, after revealing what a Reaper is to Jaune, Ruby ends the chapter [[WhamLine tearfully confessing that she is aware that Jaune is lying about his Class]]. The following chapter has her explain that she's actually had her suspicions since Book One. She'd hoped that Jaune would tell her eventually, but she ended up forcing the issue in an attempted breaking of the MutualMasquerade due to being worried about the current mission and outright needing him to use blacksmith abilities to help her.
* ''Fanfic/BecomingLifprasir'': Apparently, Fishlegs figured out that Hiccup and Cattongue were the same person at some point and kept it to himself, as Astrid discovers when she herself pieces things together. He also insists that Astrid also keep quiet about this revelation until Hiccup is ready to reveal himself.

* ''Fanfic/InfinityCrisis'';

* In ''[[https://www.fanfiction.net/s/1857017/1/The-New-Teacher The New Teacher]]'', Peter Parker starts working at the Xavier Institute and until chapter 40 (after Peter is forced to use his powers during the Brotherhood’s latest attack on the school), only a few X-Men know that he’s Spider-Man, to the extent that they even keep that knowledge from the rest of the team. Wolverine knew already, Shadowcat learns when she walks in on Peter changing out of his costume after Spider-Man helped stop a riot, Rogue suddenly recalls some of the personal information she absorbed from Spider-Man in ''ComicBook/ContestOfChampionsII'' after spending time with Peter, and Wind Dancer’s awareness of wind overhears the Green Goblin refer to Spider-Man by name when the Sinister Six take some of the students hostage.
