Hangman is the first episode of the sixth season. It was released on 25 September 2009.

The team tries to protect an activist from a sniper, while Charlie and Amita attempt to keep his proposal and her answer a mystery.


The most common Hangman reference is to the spelling game, and its step-by-step elimination process, but in this episode, Charlie describes the "Unexpected Hanging Paradox", in considering that the assassin might be giving false clues to manipulate the expectations of the investigators and thereby change the timeline and the outcome.
