While Derek Reese is dying on a kitchen table in the present, twenty years in the future he"s just another resistance fighter with a brother named Kyle who likes to tell stories about busting out of prisons with John Connor. Then he"s captured with the rest of his squad, where scary and confusing things happen. One of his squad members is an unrecognizable (thanks to his beard) Andy Goode, who confesses that he"s responsible for building the computer that gained consciousness and then took over the world. After escaping (well, more like being let go), Derek discovers that the resistance is reprogramming the Terminators; this can be good (like when they look like Cameron), but it can also be bad (like when they go all haywire and kill everybody, which is much worse than when your computer crashes in the middle of a game of Minesweeper). He also finds out his brother has accepted a time-travel mission. Kyle"s going back too, with his men, to correct humanity"s mistakes before they"re ever made. He also comes into contact with either Cameron or a Terminator who looks exactly like Cameron. And so, that is how a young Andy Goode ended up with a bullet in his forehead: from the end of Derek Reese"s gun.
And after a blood transfusion from John (whose blood type is either quite a mistake on the part of the writers or HE"S NOT REALLY SARAH"S SON), Charley and Sarah are free to have one of those awkward discussions where you run into an ex-girlfriend and let her know that you never really forgave her for running out on you eight years ago, and then supposedly dying in a bank explosion. Charley is told the truth about who Sarah and John (and Cameron, on T-888 endoskeleton disposal duty this episode) really are. The most implausible thing all episode may be that Charley didn"t wind up on the floor in the fetal position.
