"I'll Be Back."
Reese says that in a few years there's going to be a nuclear war. All of Los Angeles will be gone. There were a few survivors, but no one knew what started it. "It was the machines, Sarah." Sarah doesn't understand. "Defense network computers. New, powerful, hooked into everything, trusted to run it all. They say it got smart -- a new order of intelligence. Then it saw all people as a threat. Not just the ones on the other side. It decided our fate in a microsecond: extermination." He says he grew up after the war, hiding in the ruins, hiding from the Hunter-Killers. "Most of us were rounded up. Put in camps for orderly disposal." Oh, my God. Did James Cameron intend this movie as a Holocaust allegory? Reese shows her a red bar code on his arm. "This was burned in by laser scanner. Some of us were kept alive. To work. Loading bodies. The disposal units ran night and day. We were that close to going out forever." But on the plus side, it got him into Black Flag shows for free.
But there was one man who taught them to fight. "To smash those metal motherfuckers into junk. He turned it around. He brought us back from the brink." John Connor. Sarah's unborn son.
Since all the other cops have apparently given up looking for them, Reese hotwires the car. But as he starts it, there's creepy eyebrowless Arnie, blowing out the rear window with a shotgun.
And now we're off to the races, with Reese and the Terminator firing shotguns at each other and still able to drive, with minimal damage to other parked cars. Maybe road rage is commonplace enough in 2029 that everyone knows how to do it.
The chase moves onto the streets of L.A., Reese and the Terminator trading shots, with neither connecting. Reese orders Sarah to steer so he can stick his torso out of the driver's side window and present a nice big target for the Terminator. Unfortunately, the underpass they're in ends at a big wall, and Sarah has no idea what to do. Reese appears to clip Arnie, though, and Sarah slams on the brakes, while the Terminator is too busy...rebooting? And slams into the wall.
And here come all the cops who mysteriously vanished from the parking garage. A half-dozen squad cars pull up and block the road. Reese's instinct is to jump out of the car with his shotgun. Fortunately, Sarah stops him, telling him that they're required to have a scene in which the local authorities think the time-traveller is wacko. One of the cops goes to check the other car, but there's no one in it. Not one of the cops seemed to notice anybody getting out, though. Nice work, cops!
