And so normal service is resumed. After a long wait Terminator The Sarah Connor Chronicles returned to Virgin 1 last night.
Ellison dreams about digging up Cromartie. He wakes up to find Cameron checking his garden for the missing terminator.
Sarah has decided that the three dots means something. The gang finds a new company working on AI that use three dots as the logo. John studies the hard drives they steal and says the company has a design but needs money to implement it.
Derek confronts his gal from the future when he finds her surveillance photos of the gang. She tells him that future John is making bad choices because of his close relationship with Cameron. Future gal came back to keep an eye on John. Derek obviously has doubts about Cameron also.
The child physiologist who was helping Weaver with her AI dies in the lab. Ellison questions the AI and decides that it's amoral and doesn't know the difference between right and wrong.
Sarah poses as wealthy "Sarah Gale" and offers money to the three dot company to buy a Japanese chip they need. Eventually she realises that the three dot guy has tricked her and kicks the crap out of him before recovering the money.
(Notice the name "Gale" as in Gale Anne Hurd, the producer of The Terminator movie. I bet "Weaver" is named after Sigourney Weaver from James Cameron's Aliens and "Ellison" is named for Harlan Ellison the SF author. "Cameron" needs no explanation.)
The big shock of the episode its that John's gal Riley is from the future! She came back with Derek's gal to befriend John. Riley seems to be cracking up and wants out. This isn't going to end well.
At the end of the episode Ellison is brought by Weaver to meet "John Henry", the AI. It's Cromartie! Back! I saw it coming, but still... Cromartie! Back!
