Nice build up for the entire episode leading to the cool twist where Jack finally gets the upper hand his Captor's when he uses Ben as his way to free Kate and Sawyer. When I this air originally, I don't remember if I saw the twist coming. I do remember going "hell yeah" when it played itself out. Also, Kate and Sawyer finally hook up in a Polar Bear cage! Who hasn't had that fantasy doing it in a Polar Bear cage before?
