Two things are clear to me after watching a new clip from next week's ep of Terminator: The Sarah Connor Chronicles. First, the show isn't shying away from its recent dive into nerds-only territory. Second, Derek Reese is about to snap.

The clip builds on the bizarre conversation Derek (Brian Austin Green) had with Jesse (Stephanie Chaves-Jacobsen) last week about time travel. He suggested that they might have each come from two different cyborg-infested future realities. (Yeah, like I said, it's nerdy). Now, Derek seems more paranoid than ever while talking to John (Thomas Dekker) about the mysterious three dots. We already know that Derek tried to kill himself once before. Is he headed for another breakdown? Monday can't come soon enough.

The last few episodes of Sarah Connor have been some of the best genre TV I've seen all year. It's a shame that the show probably won't be renewed for a third season. I know I'm being pessimistic here, but the writing seems to be on the wall.
