Hmmmmm, random bullshit musing:
1. When John traveled into post Judgement Day future, he was absent from the timeline when the Resistance started, so somebody else started it, probably the Reese Bros.
2. John Henry was also absent on Judgement Day, which means he's not Skynet (pretty clear already) but... sort of an anti-Skynet Skynet? Although it's not shown in any episodes yet, T-888s supposedly have one primary chip and two backups. Two possibilities on Cameron's chip and John Henry: A: Cameron let John Henry plug her chip into one of the backup sockets, then showed him how to download his AI into the other backup chip and is now doing a 'ride-along' in the Cromartie body, or B: John Henry used Cameron's chip but discarded the Cameron AI into the server farm while uploading his own AI into her chip, ditching her.
3. The girl John meets in the future *might* be Allison Young, but then again, did we ever actually see dogs going nuts around Cameron?
4. John Henry going into the future is odd. He got his ass kicked by Skynet in the present day, why would he take himself out of the loop for 15 years while it continues to advance from that point forward?
5. I'd still fuck Summer Glau even with the creepy robo-eye showing.
6. So would you. Don't lie.
