Mmmm... Another stand-alone episode.
A new terminator has turned up with a mission to kill one of John Conner's future resistance fighters. John and Derek head off to a military academy to protect one of the possible targets. Sarah and Cameron in turn protect another target who happens to be a young boy.
Sarah takes the young boy in for the weekend while they hunt the terminator. She bonds with him and helps him write a book report on The Wizard of Oz. Seriously.
John gets enrolled at the military academy and Derek gets a job as an instructor, one assumes without references. They manage to dispatch the terminator.
Sarah puts the kid on a bus, unconcerned that he'll probably tell the cops about the crazy ladies with guns.
This episode did not have the ring of truth somehow.
Meanwhile agent Ellison investigates the terminator fight at the power plant from a couple of episodes ago. He reports back to Shirley Manson and she then cleans up loose ends behind his back.
Oh well. At least Lena Headey and Summer Glau were looking well.
