what happened to ... *spoilers*
Somebody else posted this same question, what happened with Troy? I assume Tommy killed him, but do we have any evidence other than Tommy having his car? He was kind of a jerk anyway :-P
Also, the girl that came on to Tommy that he hit, and then they found her body the next day ... when we first saw it on the news, I figured that Tommy killed her kind of accidentally, just by delivering that one big shot to the jaw of a fairly small teenage girl, which might be enough. But when we see Tommy being very violent on several occasions after that, maybe he just went off on her like he did a couple other times. So what exactly became of her ... I guess my question is, did he kill her on purpose or by accident?
