So what's going down in your returning episode?

Well, basically Weston comes back about four days after the beating, so he's still very physically affected, and we see it on him. There's still cuts, bruises, scars. He's still physically in pain and affected by that. He's also emotionally and psychologically affected by it, and we see that in his social interaction with the team and also with the followers. Emotionally, I think he probably wasn't ready to come back, but I think he was as frustrated as the rest of the FBI at this point. We are getting so close and yet Joe Carroll is always a step ahead, and I think he doesn't want to waste time. He probably could have spent three or four more days resting, but he was like "I need to get back to the case; we need to get to the bottom of this." I think there's a certain aspect of revenge there. It's consuming him, and I think what's really fun about what happens to Weston is that we sort of see in a mirror how Ryan Hardy (Kevin Bacon) got to be the way he is. Over the season, Weston is affected by the violence that he sees, and now the violence has been inflicted on him. I think we get to see how Ryan got to be the way he is, by what's happening to Weston. So I think it's a complete parallel and we experience a lot of that.
