I just have caught up with season 3 of bones.
I had heard one of the cast was going over to the dark side and thought it was going to be Zac he seems to have been acting a little off for most of the season.
And when the lobbyist was killed thought the murder looked like Zac.
Did nearly changed my mind in the last ep because i thought sweet had the eyes of a killer but when Bug guy put his own home in the frame i knew i was right with my first choice.
I would have liked to know more about the master and how he turned Zac but i supposed that was because of the strike.
