Cabmom, I think that when Christopher was looking at that family with the kids and the junky car he was imagining his life outside the "family". You see him looking at his $$$$ Hummer, then looking at them (what were they driving, an old Chevy Citation! Remember those?!) I think he was thinking he is better off the way his life is than the way it would be on the "outside".
I really thought he might go along to the Feds the way he was talking to her. I also believed Tony's call about the suicide. Then, when Sil was not looking too upset in the car with her, I knew she was in trouble. I was literally holding my breath when she was telling Christopher about her involvement with the FBI! Then I thought he really would kill her right then. But when he stopped, I thought that maybe he would turn to the FBI. Guess I was wrong.
Great bit of acting by the cast tonight, especially Christopher. It really got to me me when he was moaning "What are we gonna doooo!!!"
Too bad we have to wait two weeks. I can't believe the season is over already. Do we have to wait another 2 years for the next one?
