ladies and gentlemen, Tyler Posey in all his glory
If Derek's arc does end, I don't think it'll be bc he dies. I think he'll probably just...leave. Maybe with Braeden. Probably with Braeden honestly. That being said, I don't think TW stands a chance in hell of making it to season 6 without Derek. Their ratings are already down to the same point they were when they STARTED. Getting rid of Derek would be the final nail in their coffin.
