Yeah, Colton left because they were only going to show him in only four episodes. He was a main character, so he didn't really want to continue the show. Also, I heard there were salary complications, and he (Colton Haynes) took Teen Wolf off his resumé.

So yeah... Colton was basically "taken out".
