Sometimes, for whatever reason, a [[TheObiWan mentor]], a QuestGiver, or someone in the know has cause to lie to the heroes. It's not necessarily even for its own sake, in fact it may even be with the best of intentions. However, inevitably it comes to a point where instead of helping, continued deception will cause more harm than good.

Most of the time, this is when the characters have to let the truth out, no matter the feelings hurt, the harmful secrets revealed, the comfortable illusions shattered.

The NoMoreLies moment is that point, where the plan is no longer furthered by lying. Sometimes, in fact, the plan has already been hindered and the mentor has no choice but to part with the information. Sometimes the mentor is a ManipulativeBastard and only gives the information when he knows the Hero will have no choice but to keep going. Sometimes the hero does have the choice to leave, and that choice is precisely why the ManipulativeBastard version was waiting.

[[folder: Literature ]]

* ''Literature/KingdomsOfThornAndBone'': z'Acatto needs to tell Cazio that his own drunken stupidity led to the death of Cazio's father because if he didn't he knew the young man would chase shadows until he died.
* ''Literature/TheLordOfTheRings'': Aragorn shows himself to Sauron in the palantír when there can be no more gain by hiding himself and who he is.
** Well, that and it's also part of a larger deception to convince Sauron that he has the ring -- to draw his attention away from their ''real'' plan to destroy it.
* ''Literature/HarryPotter'': When Dumbledore tells Harry what little he hadn't pieced together about Voldemort and the Prophecy, he lampshades this pretty well verbatim. Although even then, he did leave one final vital nugget of information that only comes through in the final book.

[[folder: Multiple Media ]]

* The Turaga elders in ''Franchise/{{Bionicle}}'' decide by themselves to share their secrets about the lost city of Metru Nui, reveal the islanders' true origin and their forgotten past lives, and also that the Toa they had been mentoring weren't the first heroes to walk the land by a long shot -- but first wait for the Kolhii championship to be over. However, events that occur directly after the match lead to the actual discovery of Metru Nui, so they have no choice but to tell their tales. This was also a huge relief for Matoro, the only villager who had been aware of it all but was asked to keep silent around his people.

[[folder: Video Game ]]

* ''VideoGame/DragonAgeOrigins'': The Grey Wardens are made of this. They keep the Joining ritual secret until the last moment, and they keep the HeroicSacrifice needed by a Warden to slay an Archdemon secret until the end.
* ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' has Zelda, who knows about the Triforce and who has each piece of it, but she waits until she has no choice to tell Link.
* The ''VisualNovel/PhoenixWrightAceAttorney ''series has several of these, often when Phoenix's clients are innocent of the crimes they're accused of but hold off on explaining the full truth to Phoenix and the court until the climax of the trial. One major example involves Lana from the DS version of the first game.
* When you receive Mordin's loyalty mission in ''VideoGame/MassEffect2'', he tells Shepard that he wasn't entirely truthful about his previous work in the STG, studying the effects of the genophage -- [[spoiler: when they discovered the krogan were adapting, he and his team revised the genophage to keep the krogan subdued]].

[[/folder]]

[[folder: Web Comic ]]

* Webcomic/GirlGenius has Baron Wulfenbach say the "no more secrets" version of this to his son Gil. Of course, it's also of the "I'll tell you after the big plot event" so Gil still doesn't know anything. [[spoiler:And now the Baron may be dead.]]
