Or she is manipulating Jesse into thinking that it was part of the plan and she really did want to die. Also likely because we've seen some of her outbursts in Season 2.0 (threatening her Foster Parent for example).
I'm leaning towards this interpretation, though it might not be intentional manipulation, but rather Riley covering so that Jesse isn't too angry with her. We've already seen Jesse smack Riley around a bit, so I suspect Riley is scared of displeasing Jesse.
I'm equally leaning to that interpretation. Riley managed to turn a bad situation partially into her advantage, and she both avoids displeasing Jesse too much and she gets attention from her at the same time.
Regarding Weaver, what a cool scene when the director first lingered on the urinal (we expect it to
be Weaver), then the basin, then the mirror (we expect to see Weaver coming up from behind) ... and then she just does a "walk-by killing". Some people hate Shirley Manson on the show, but I just loved every scene with her in this episode (and most of what she did in S2.0 as well).
I'm still not sure what her game is though. She is collecting coltan, and "everything she does, she does for John Henry". But why does she want JH to be taught by Ellison, then? Ellison and her other assistant got a narrow escape, by the way. If JH had told them about Weaver...
I also really liked Derek in this episode; very competent, and he also managed nicely to thrown John's words back at him. Cameron was a bit cold this time around, she missed a chance to "support" John and talk about his future self. Loved the scene with Riley, John and Cameron, though.
Some parts with Sarah did drag a little, but it is the Sarah Connor Chronicles, I suppose. All in all I voted above average. Pity the ratings are so bad; I so want that third season. What is the remaining chance for that? Could WB really go to another network if the worst happens or is that chance very low?
