If this is the last season there is only twelve episodes to wrap everything up."I'm not making an announcement today about when Dexter will end. I think I will clarify before Dexter goes on the air for this next season. There's a clear endgame in place; I just can't talk about it just yet." Nevins did reveal, "The decision of when to end Dexter is ultimately a creative decision and will be made on creative reasons."
