This episode deviates from usual in two ways. 1) There is no murder in the first act. 2) The normal pattern: Act I depicts the events leading up to the murder and Act II replays them from Charlie's point of view. In this instance, the two acts run parallel to each other, not converging until right before the second ad break.
