I don’t think he’s gone to the bad side. I’m thinking that he’s pretending to have it out for H, and is working with the guys who want H dead. When the time is right they (people who want H dead) can be flushed out, and guess who will be there waiting for them? It was a great choice using Ryan as possibly going bad. It will make everyone (rest of the CSI’s) think that he is still pissed off at H for firing him last season. Maybe he and Eric will come to blows and Ryan will have to take his shirt off.
