Yep, Famine, I'm a big fan of the show. I've just about given up on network television, as I hate reality shows, the dramas are just getting ridiculous, and there hasn't been a good sitcom in ages, but "Nip/Tuck" has given me hope that television might have a few breaths left in it. Of course, it IS on cable, so the networks are left holding the bag again.
I was actually hoping that the season finale would clear up the entire "Carver" storyline since the Escobar storyline from Season 1 was tied up nicely in that season's finale, but once again, they threw a major curveball with the final scene. So even though we know the nature of particular characters which I won't spoil for those who haven't seen it, we still don't know who the Carver is. Irritating in one way, but it keeps my anticipation for next season going, which I guess is the point.
I have my own theory on who the Carver is, and it's kind of out there. I won't go into it here, as I can't find a font color that is difficult for people to see without highlighting and there doesn't seem to be a spoiler tag for highlighting/obscuring. I don't want to spoil anyone on my theory, so if you want to PM me and discuss it, feel free to do so.

Cool to know that another SW fan is watching!
