Hitting for the Cycle - S11-E18
Continuity mistake: Series 11, Episode 18, "Hitting for the Cycle": At the very beginning of the episode they are talking about the cycle while looking at the board. The three main ones, Suicide, Accidental and Homicide, are together on cards with a space above and then two more cards. The scene then goes out to show the CSIs again, and there are now four cards grouped together on the board.
Nick Stokes: There's a sucker born every minute.
Gil Grissom: Yep, and they all come to Vegas.
Question: Why would Catherine take the blame for the lab explosion? If anyone was to blame it was Hodges. Since he accidentally turned on the hot plate and even admits that sometimes it gets switched on by others accidentally, if he had bothered to make sure he didn't switch it on before leaving the room, the explosion never would have happened.
