2x21 "Adam Raised A Cain"
Wow, I was totally blind sided by Derek's death. I can't believe it, that he's actually dead. I think the way they did it was better than having him go out the "hero" - It had more of a shock impact ! Still, I'm going to miss his character. He was buried in the same area as his brother, but not as his brother. Sad.
Then Sarah is apprehended so it's just Cameron and John now and they will become closer than ever.
The more we see of John Henry the more we see that he is not the bad side of Skynet. He's the side that respects humans and Savannah has a lot to do with that, much to Catherine's dislike. She'd have preferred if Savannah did not come home.
I thought this was a great episode.
