I have a question, we know already that this is going to effect him physically, emotionally and spiritually, we've already seen a bit of it already in the episode, but is it going to effect him in other ways? Like, when people have a near death experience they sort of do things that are reckless or dangerous because they sort of have to deal with surviving. Would he have an edge to him that he didn't have before, will he become a little angry, or would he also sort of start taking unnecessary chances that could do him harm?
I've been just thinking about that because while the spoilers for some future epi's have him acting like Greg and he's fine, (he admits in Post Mortem he's having problems sleeping, but at the same time, he's supposed to totally nail his testimony like a pro) I'm wondering if something is going on that we might not be seeing (not just him beating himself up over it-that is a given, Greg is sensitive) until maybe later on in the season.
