Low points, as usual, involve the children. John Ross is still a whiny pissant. Anne's daughter hasn't been on the ranch ten minutes and already she's boinking Ewing men. Jordana Brewster was wasted this episode.
I'd argue that it's Christopher who is the whiny pissant. John Ross has an excuse this week, considering his daddy is dead. Emma just came from a situation where her every move was being watched and controlled. I'm not at all shocked that she was getting high and screwing John Ross... because her grandmother and father aren't there to keep her from doing those things. It was she who was "wasted."
Elena was definitely underused, though, and this subplot with her and her brother is not going to do much to help with that.
