Well, when you face metal killing machines daily, expect to get unlucky once. And once is all it takes.
Also points for the first truly effective musical montage of the series. *sniff*
As for Ellison, I feel for him. Poor guy must be incredibly confused by this point. He knows what the Connors do. He knows what John Henry is. He's right in the middle and I doubt he's managing to put any complete picture together. Aside from probably being terrified of Cameron.
I believe him, BTW, on the matter of not calling the police. He got Savannah. That's all he wanted. He had no reason to put Sarah away. I'm looking forward to him finding out that his boss is metal.
I don't even want to THINK about what John is going to try to do. Hopefully Cameron will restrain him. Or possibly she could recreate T1 on the police's ass?

Also, American viewing public? Fuck. You. Seriously. And fuck Fox executives for being so narrow-minded. Hulu ads. DVD sales. It's not all about the first airing. Which you guaranteed no one would watch, just for the record, by the infamous timeslot. Do you hate quality sci-fi shows? Is that it?
Go make another season of Wife Swap or something.
