Derek strolls into the room and plops down the chip Cameron saved from the T-888, saying he found it in her room. "Why were you in my room?" she asks. Sarah's more interested in the fact that Cameron lied about destroying every last piece of the T-888, and Cameron says the chip contains visual records of the Terminator: where it's been, who it interacted with, etc. Derek bitches that that's the only truly irreplaceable part of the machine, and Cameron kept it. "Next she's going to tell us it'll help us find the Turk," he snaps, but Cameron says it won't. John wants to know what Derek's getting at. "She can't be trusted. No matter how she acts on the outside, we have no idea what's going on in there," says Derek. "Well, I could say the same about you," says John. You could, but you should probably at least append "no gives back, infinity" to the end of it.
Since he's getting nowhere with John, Derek tries convincing Sarah, pointing out Cameron was the one who told the Connors about the safehouse. "Who else knew about it? Nobody. Where are my men? In the morgue." Cameron says she didn't tell the T-888 about the safehouse. "Prove it," says Derek. John shifts the topic slightly to ask if Cameron's ever hacked one of those chips. "No. But you have," she says.
John and Cameron head to some kind of video game café where some people are playing some Halo-like game (if not actual Halo, I don't know) on giant screens. John asks Cameron how often she lies. When the mission requires it, she says. He asks if she lies to him. Yep. "About important things?" he says. You mean like Yes, I destroyed all of the T-888? Yes, John, about important things. Jesus.
Anyway, some guy comes out with some machinery with dual-core processors and Johnson rods and genectagazoinks and whatever, and John speaks dork right back at him, and apparently this thing is really amazing and will let John create actual human life like in Weird Science, and he takes two, and there is now probably a picture of John on the wall at that café: "Dude is so hardcore he bought two."
John asks Cameron if he's making a mistake with the chip thing: "Do I wanna see what's on it? Tell me now," he says. "I'd rather tell you after," she says, which makes no sense at all unless she knows what's on the chip. If she's trying to imply that she can't tell him if he'll want to see it because she doesn't know what's on it, wouldn't she say, "I can't tell you until after" instead of "I'd rather tell you after"?
