This show is clever. I so hope, it’s not gone.
I’ll start with the one thing that bugged me: the pacing. They rarely get it right. Once again, the episode felt too slow in the middle and awfully rushed in the end.
But there is so much more to love that I feel no desire to complain … yet:
The way the travel into the future played out, adds evidence to the one-timeline-idea behind the terminator universe (at least in TSCC) and this approach is crucial to add morals to the story.
In a many-world-universe, whatever one of your iterations misses to do, the other one does – actions have consequences within one timeline but not within or for the whole. On TSCC, your iterations vary their actions too, but every single one of them adds to the outcome of the whole:
John jumps into the future, therefore he never became leader of the resistance, Kyle had no reason to go back and neither did Derek. But since one Kyle did it once, this John still exists.
Something similar might be true for “Weaver”. I think, the writers realized early on, how alien the liquid “metal” is to the mechanical ones and how unlikely it is, that they are of one origin. It can’t be a coincidence that the writers have drawn parallels among Skynet, John and Weaver: they are all born by a loop, that they continue to establish.
In contrast to Skynet and John, however, who are one loop, Weaver’s alieness might be evidence that she is also of a different time. If that is “true”, her loop might contain the Skynet/Connor one and might even have caused it – or vice versa (dependent on what happened first: the past or the future).
Anyway, the newly established timeline could be a major step to open up the repetitive loop, the world seems to be imprisoned in. And this might be the rationale behind Weaver’s actions and her words towards John Henry, when they talked about Abel, Cain and God.
And by jumping into the future with John, she made sure, that he couldn’t undo for a decade and more, what she had set into motion.
Whatever it was, it wasn’t supposed to stop Judgment Day, because Weaver didn’t seem to be disappointed by the state of the future, they both jumped into.
And though Sarah promised John to keep on fighting, she failed, once again, to stop what was coming, but she won’t have failed to prepare some support for John. Ellison and Savannah will be prepared too, for what, I don’t know, but I’m sure, Weaver is already looking for them and John Cameron Henry.
All pieces are set for a finale: John is in a future, that doesn’t know him, but was still created by his decisions, this Kyle has not disturbed the timeline, he, Derek and Allison are John’s links into the resistance, Skynet and Weaver are going to complete their plans and John Cameron Henry might decide, how the dices are going to fall.
Damn, we need another season.
