Well I for one like the Tony situation, it feels like the early seasons of 24, that even when you knew he was a good guy, you really couldn't trust him 100%. The way the show sets him up you always thought he could be a traitor or backstab someone. I think we'll keep seeing more of that ambiguity as we continue throughout the season.
Not much left to say, since this was a more action oriented episode more than anything. Liked the scene in the chemical plant, and they got a pretty good tv actor for that small role, so good stuff in my opinion.
