This is where a character, usually a spy, will explain the dangers posed by a specific individual being among the group. He will often go into such detail that there's no doubt in the audience's mind who this person is, but most of the time the people he is addressing will be oblivious. In fact, the opposite will often occur where someone will exclaim that he knows everyone and there's no possible way it could be any of them.
Often used by a Villain to invoke Spot the Impostor to create paranoia, gain a character's trust or both. Not to be confused with Most Definitely Not a Villain as this ruse is generally well thought out and only audience is able see through it.
- Guy MacGuffin does this is in SpyBoy.
- Used in Breach when Robert Hanssen, based on the real life FBI agent convicted of being a Soviet spy, who is part of the team looking for The Mole. A bit of Truth in Television as the real Hanssen hacked into a fellow agent's computer and produced secret files which he presents to the person whose computer he hacked. It was later theorized that Hanssen did this to cover his tracks when he hacked the computer to see whether he was suspected as a spy.
- In the books of The Witcher series a vampire participated in a small talk about vampires. He even recommended some "folk remedies". Including garlic (which he ate at the moment). Of course, in his case it was more fun than precaution: greater vampires of that world are Nigh Invulnerable and before this incident he once was dismembered and buried in several places for a few years, then "got better" anyway.
- And in one of the later books he did that again, this time arguing the vampires' vulnerability to silver. He explained they can't even stand the touch of silver. All the while gesticulating with a silver fork in hand.
- Burn Notice:
- In one episode Michael Weston is doing some spy-hunting for a client until he realized the client was a bad guy. So he decides to become the actual mole, and then keeps the client paranoid (and thus dependent on Michael) by telling him all the things the spy could do to him.
- Another time Jesse works as a security consultant for a Corrupt Corporate Executive CEO. He calls the security guards at the gate to him so he can explain to them how their lousy security measures can just allow anyone to walk in through the gate. Cue Michael walking in through the gate as the guards are looking at Jesse. The entire scheme centers around Jesse constantly warning the CEO about how bad his security is specifically so Michael has an easier time penetrating that security.
- The Whitest Kids U' Know: In the sketch "It's Illegal to Say", this trope is invoked. It quickly becomes clear that the message telling the audience that it's illegal to say you want to kill the President is a cover for describing a plan to kill the President with a mortar launcher.
