Which one was Walsh looking for? Zoe's father or Winston? I suspect Zoe's father.
Yeah, this in itself almost seems like an error. If Winston survived (which I still find very hard to believe given how close the gun was to him) and was taken away to receive medical treatment just like Sarah, Weaver should have known something about that. Perhaps she already was looking for Winston, but that's not how that episode played out. He should've been an easy target to find.
While it is not impossible, it would also be drastic for Weaver to shut down her own operation like that, if it was hers. In the intercepted message, they were referring to an evacuation and "you know the drill", so procedures in case of a security breach were in place. Even if Weaver simply does not tolerate sloppyness (the unsecured line), wouldn't killing the persons directly responsible have worked?
Weaver has this strange tendency to kill people for the slightest reasons. She first killed one of her employees just because he expressed doubts in her. I could see her killing everybody involved there over the breach. Weaver tells John Henry that his interception of that transmission was a mistake. If it's some rival company of Weaver's, you'd think that it wasn't a mistake at all. She needed to destroy every trace that might lead back to her. She must be aware of resistance factions, and she probably assumes it was a resistance member who shot Winston.
On the producer's blog, the return of at least one S1 character - previously unseen in S2, so not Charlie - has been announced. There aren't that many candidates; Carter is one of them (I guess Cheri, Morris, Terissa Dyson, Dr. Silberman are the most prominent of the others). So, maybe "he'll be back".
That sounds interesting, but I still have doubts that it's Carter. He was meant to be forgotten. I have the feeling that the one returning would be Andy Goode or one of Derek's associates when he was imprisoned in that house, since that basement mystery is supposedly going to have some light shed on it.
Weaver's character is rather ambiguous now. She kills easily, true, but Cameron is almost as quick to kill. The most curious thing about Weaver is why she would possibly want JH to learn "morals", and she does seem to spend a wee bit more effort on Savannah than strictly necessary for her cover. At the moment, we don't know what Weaver's exact goal is, but she doesn't act the way Carter did. Her "crossing against the light" comments early on were also interesting.
I don't think she ever really wanted specifically to teach it morals so much as Ellison convinced her that JH needs to learn morals. Perhaps she's ok with it seeing as how Ellison's "morals" are Biblical and she was all quoting the Bible before. Plus, it's possible that the Skynet she knew developed with those morals. Given the nature of the Bible, Skynet might be acting as God did in the Old Testament, or disregarding those morals knowing that the book isn't exactly flawless. It wouldn't be the first time it was used to start conflict. I'd rather the religion stuff not be the case, but it might be what the writers are going for.
As for Savannah, she really hasn't had a reason to kill her. She poses no threat, and gives Catherine an opportunity to study humanity more. It's certainly not genuine compassion because her character is shown to be void of that in relation to other humans. It's also possible that Savannah grows to be someone important.
That does not have to mean she is pro-human in any way, but what if she was send back by a Skynet that was desperate and losing the war in the future, and they may want to try another approach instead of nuking everything?
That's a possibility, but it's strange to have a Skynet that wants to kill John Connor or other resistance members, yet somehow just this one terminator has such a different motive. I could accept it as a rogue terminator faction from the future or something, but even that seems like a stretch here.
Allthough it does seem that Winston and Zoey's dad, who were the killers in the operation, may have known more than the other employees. They did make off with the drone, in any case.
Yes, I found it curious that they were the ones who survived and were both on that surveillance video. They have a potential to be "grays" from the future.
