Adama: You're right. There's no Earth. It's all a legend.
Laura: Then why?
Adama: Because it's not enough to just live. You have to have something to live for. Let it be Earth.
Laura: They'll never forgive you.
Adama: Maybe. But in the meantime I've given all of us a fighting chance to survive. And isn't that what you said was the most important thing, the survival of the human race?
Liar Revealed is the Internal Reveal of The Lie, the facade maintained by a protagonist which provides the primary dramatic tension for the plot. This usually sets up the third act where the protagonists are forced to deal with the consequences of the lie on top of any external threats.
The magnitude of the lie is important. It usually involves one or more of the protagonists setting themselves up, intentionally or accidentally, as something they are not, and other characters buying into the lie such that failure of the protagonist to live up to the facade may be disastrous. For example, a main character receives praise for an act of heroism they didn't actually commit, then is put in a position where he will have to repeat his feat to save the day again, only to have their deception revealed just when people are counting on him most. (He will usually then proceed to save the day anyway, earning back the trust of those he deceived.)
There are a few usual ways this ends up. If the lie was for selfish reasons, the protagonist will doubtless face the wrath of those he lied to, but along the way end up having a change of conscience, and try to redeem themselves through good acts and An Aesop about "what really matters". If the lie was well-intentioned, the protagonist may still find that others turn their backs on him, but go on to carry through with what they said they'd do anyway, proving themselves a hero after all.
It's worth noting that this trope is particularly easy and common to misuse, either in the tendency of the protagonist to Maintain the Lie for reasons that make no sense except for dramatic tension or of the deceived to turn against the protagonist for the deception in spite of other considerations that should by all rights absolve him.
- Love Hina uses this for when the roommates discover that Keitaro is not a Tokyo U student early on. This leads to their already fairly low attitude of him sinking even lower.
- This occurs in a months-long storyline for Retail. In an effort to get a raise, Josh fabricates a story to his bosses that a competing retail store offered him a job with bigger salary. Much to Marla's protest, their district manager, Stuart, authorizes the raise. Weeks later Marla finds out that the store never offered him a job. She promptly tells Stuart, and while he warns against firing him, it's pretty evident that he's pissed at the whole thing, judging by a later strip which showed Josh calling him.
- Josh, realizing he was going to get fired, got a new job and gave a two-weeks notice to Marla, who ended up firing him anyway without working out the notice after he bragged about how he got away with lying.

- Near the end of Madagascar 3: Europe's Most Wanted, Captain DuBois confronts the Zoosters backstage at a circus actnote , pursuing them and revealing that they were from the zoo all along, forcing them to give up the act.
- The LEGO Movie applies this trope for less than a minute.

Luckily, she figures out he isn't quite the fitting Special easily and this promptly upsets her.
- The Tigger Movie applies this trope when Tigger mistakenly believes that his family is coming to visit him (after having gotten a letter from his friends who were trying to cheer him up). It's zigzagged several failed attempts to reveal who had written the letter to a very busy Tigger, Roo and the others decide to disguise themselves as Tigger's family to cheer him up and Tigger learning the truth (much to his great disappointment), therefore playing this trope straight.
- The titular character of Yellowbird, who had been keeping a secret the entire film, finally spills the beans near the film's end. Karl, not him, was meant to lead the flock to Africa, per the instructions of the flock's late leader Darius. Not only did he have no clue where Africa was, they weren't aware he didn't either. He tried to defend himself by stating that was the first time he'd ever been part of a flock and felt appreciated, and that all the misfortune that befell them was his fault. The other flock members are shocked and disheartened, most of all Delf, who'd come to view him as a good friend.

- In Housesitter, the main characters (Steve Martin and Goldie Hawn) lie their way through the movie, posing off as a separated married couple, Martin trying to win back his old girlfriend, and Hawn trying to milk the house and money from the lie for all it's worth. At the end of the movie when it looks like the lie is finally going to be revealed, it isn't. The townsfolk go on continuing to believe the whole story, and Martin and Hawn don't ever tell people the truth.
- Oz: The Great and Powerful plays with this. When he comes to Oz, Oscar is believed by everyone to be a great and powerful wizard destined to save them all, which he just runs with so he can become king. As early as the second act he outright tells the truth to Finley, who's stuck with him because of a life debt, and briefly frets over the repercussions. Glinda and the rest of his friends figure it out on their own, but they're all fairly accepting because he still gets things done, and because they know he's truly good at heartnote . The rest of Oz never learns the truth, while the Wicked Witches are ultimately fooled by his lies.
- In Pokémon Detective Pikachu, this is Inverted in the second act, which ends with Pikachu seemingly getting revealed to have been Mewtwo's accomplice before losing his memories.

- In Saw 3D, the protagonist is tested by Jigsaw because he never was actually put in a trap by Jigsaw but has lied to the world saying he was in a trap where he had to put hooks in his pectoral muscles and climb up to a light to deactivate a switch to escape.

He then has several traps aimed around everyone who helped him lie including his best friend, his publicist, and his lawyer all in traps that he has to save them from, which he fails them all. He then finds his wife, where he is forced to confess he never was tested by Jigsaw before this point, and Jigsaw forces him, as an ironic shout to him, to try and recreate the trap he made up to hit a switch that will save his wife from a Brazen Bull. he fails this as well and she burns to death. The whole movie is basically built on the Liar Revealed trope, showing disastrous outcomes when in a horror film.
- The first scene that is unrelated to the rest of the film where Brad and Ryan are bound to a double-bladed bandsaw and Dina is above the third blade jutting upwards is all a part of this as well. At first both men try to kill the other by pushing the blade into the other one in order to save themselves and Dina... until Dina essentially reveals that she's been playing both of them for money and comfort at the same time, thus cheating on both of them. Brad and Ryan decide to spare one another, resulting in Dina's death.
- A variation of this occurs in The Waterboy, where the Cougars crash the Mud Dogs' victory party to announce that Bobby's high school transcript was fabricated. This causes the entire Mud Dog team to abruptly turn their backs on him, in spite of everything he did for them.

He keeps the lie up by mentioning that she was at certain events that the main character was at, and claiming that they keep missing each other. Eventually, the protagonist becomes enamoured with her imagined being, at which point Victor seduces him and reveals his attraction. Basically, Victor created the character of his sister to deal with his feelings of attraction to the main character.

- In Uncharted 4: A Thief's End, Nathan Drake's brother Sam—long believed to have died in a Panamanian prison escape—returns, claiming that he needs Nate's help to find Henry Avery's pirate treasure in order to pay off a debt owed to drug lord Hector Alcázar. However, Nate learns from the Big Bad, Rafe Adler, that Alcázar had already died in an Argentina shootout six months before, and that Rafe bribed the prison warden to get Sam out, knowing that Sam had information on the treasure's whereabouts. This angers Nate, who was putting his own life and personal relationships on the line for what he thought was rescuing his brother.
- Though the trope itself is Older Than Dirt, the trope title is at least partly cemented here vis a vis The Nostalgia Critic and other videos by Doug Walker, where Doug lists it as number 2 on his "Top Ten Worst Clichés". In other videos he notes that he absolutely hates this type of plot for creating weak drama and very rarely sees a movie where he thinks it works (How to Train Your Dragon and Madagascar 3: Europe's Most Wanted being notable exceptions).
- In Danny Phantom, this trope is seen briefly in the third movie, "Reality Trip". It's used twice in the fourth movie/series finale, "Phantom Planet", as both Vlad's and Danny's identities are made public.

- In one particular episode of Spongebob Squarepants when Mrs. Puff passed Spongebob too early on his driving test.
- Averted in the My Little Pony: Friendship Is Magic episode "Sweet and Elite", where it looks like this is being set up when Rarity lies about Opal being sick, so she won't immediately have to travel back to Ponyville for Twilight's birthday and miss an exclusive garden party with Canterlot's high society. However, the truth is never discovered and the Aesop is about something else entirely (loving and not being ashamed of your friends even if they aren't as sophisticated as others think they should be).
- In fact Rarity lies to people at the party about her friend Dash being the Wonderbolts' trainer, yet this is never brought up again even after all her friends, including Rainbow Dash, show up and then eventually join the party.
- Subverted in Star vs. the Forces of Evil. In a earlier episode, Marco helped depose Miss Heinous as headmaster of St Olga's Reform School for Wayward Princesses while disguised as a princess and he maintains the charade when visiting the school later on to avoid disappointing the other students who all look up to "Princess Turdina". However, when Miss Heinous exposes the truth—fully expecting it to cause everyone to turn on Marco and allow her to return as headmaster—the princesses are surprised, but in the end, they admit they don't care. Partially out of appreciation for everything Marco has done for them and partially because they all really hate Miss Heinous.
