I agree with ide_cyan, I think Weaver wants Cameron, and is going to use Ellison to find her. Someone on my flist suggested that Weaver is to Skynet what Sarah is to the Resistance -- creator/mother/trainer (programmer?) and I really love that idea.

I have to admit, I was all set to be REALLY ANGRY that Michelle was being killed off, but then I realised, this is how you kill a female character without putting her in the refrigerator. That, combined with last week's nonsexual portrayal of nude!Sarah, is one of the reasons I love this show, even when the writers are clearly smoking the crack.
