Sometimes, for whatever reason, a mentor, a Quest Giver, 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 No More Lies 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 Manipulative Bastard 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 Manipulative Bastard version was waiting.
