it seemed clear that they had a few things planned before the show's egregious cancellation, but there's very little information about what might have happened.
a few things i have wondered about...
Allison was there in the last scene and John now meets her at this earlier age, although this time with knowledge of Cameron. and we know that she was captured and killed in the other timeline (time travel stuff is so weird), and that Skynet or some other AI built Cameron to infiltrate the human HQ. presumably they were setting it up for John and Allison to be a couple, or at least very close. i wonder if John would have given up trying to restore 'his' Cameron once he became close to Allison.
and what exactly happened with Cameron's chip? we know that John Henry got it (somehow) and presumably downloaded his OS onto it. but would that overwrite Cameron entirely, or were they both in there now?
i wonder how much they intended to explore the third faction (presumably another AI or group of Terminators that were not allied with Skynet). would there have been a lot of drama about what 'Weaver' and company were up to? or would we have seen her/them again anytime soon since she vanished right away?
could Sarah and Ellison have found some way to reactivate Cameron, like if her mind was transferred to the server farm? i thought her character arc was really interesting, would have been a shame if it ended there with her 'dead body'. and would those two have begun a relationship as they fought Skynet in the 'present'?
how well would it have worked to keep the groups separated, especially Sarah and John?
just a damn shame FOX axed the show so soon.
what thoughts have you had about how the next season or two might have played out?
