They steal a Jeep as Cameron slowly strolls out into the middle of the street behind them, and then, after John and Sarah zip around a whole lot, Cameron manages to wind up in front of them as they try to head into a drainage culvert (because John thought it worked so well in T2?). Cameron swipes at the Jeep as it passes by, causing it roll over.
After coming to, John reluctantly, as per Mama Connors' orders, skedaddles, as Cameron limps towards them. Sarah painfully pulls herself from the overturned Jeep, and Cameron orders her to call to John. Sarah refuses, and Cameron realizes that's a dumb plan anyway, and continues after John, easily swatting Sarah aside.
John stumbles into a warehouse and hides behind a cargo truck. Cameron follows, and turns on her infrared, but not her super-hearing, as she can't hear John scuffling around and grunting. John hops into a truck and tries to hotwire it, giving away his location. Cameron hobbles over, helping herself to a massive wrench and then chucking it through the windshield after John gets the truck started.
Just then, Sarah comes roaring into the warehouse, having already come to, found a truck and sussed out the situation inside. She slams into Cameron and pins her between the grilles of the trucks. John scrambles out the windshield to deactivate the immobilized Cameron, and it takes him half an hour to do so because Cameron begs him not to do it. She claims to have run a test, and she's fine now. She says she's sorry, and turns on the waterworks. And when that doesn't work, she tells John she loves him. John finally pulls out her chip, which is going to make things awfully awkward. I've been there, man. Tell someone you love them, and they deactivate you. Classic. I recommend Disintegration by the Cure.
Derek examines a prone Cameron, and goes over to commiserate with Sarah, being tended to by Charley. Seems Sarah finally got around to giving Unky Derek a call. Finding out John's been witness to (and participant in) some traumatizing events lately, Derek wanders over to have a heart-to-heart with his nephew, mainly consisting of "I told you robots are no good." "She was different," says John, meaning "hot." "She's not different," says Derek. John insists that there's physical damage to her chip, which means she can be repaired. "I need her. She saved my life," he says.
Derek gives up, so Mom comes in to be the good cop and tell John she's proud of him for what he's done today. But she can't let him try to fix Cameron. "So burn her," says a cold John. "Let's get the hell out of here."
