I can't wait for the next season also.. It's been a while since I've watched a show's full season, watched all of Nip Tuck.. and so far all of Lost (but damn they need to play the next episode already..)
I watched it, I thought it was pretty damn good...to be honest I had an idea that Quentin was invloved but then when I saw the father kidnap the kid I thought maybe he was the Carver....
Like Garrick said though I didnt like how they left a few things for guessing but I guess that leaves us in suspense for next season .....overall I thought it was a damn good episode.
