Derek finds the T-888"s chip stashed in Cameron"s room and confronts her with it. Cameron admits to John that sometimes she lies (even about "important things") when the mission requires it. John decides to hack the chip to see what"s on it. He discovers that the T-888 (human name: "Vick Chamberlain") actually appears to have been married. It"s an advanced model, explains Cameron. The images also seem to include shots of the T-888 killing his wife, and the Connor Crew set out to find the body.
What they find isn"t Mrs. T-888, but a dead lobbyist who opposed a controversial Los Angeles city project, a computerized traffic system with a centralized database, which could be Skynet"s future body (with the Turk being its future brain). The system was the pet project of Mrs. T-888. Rather than blow up City Hall (Derek"s idea) John wants to plant a virus in the system, so civic officials think the program itself is no good. The program also seems to be the source of some marital discord between Mr. and Mrs. T-888 (she"s having trouble finishing the project), but he"s got some moves, man.
Meanwhile, Chrome Artie continues his mission to hunt John down, killing school administrators, bullying coaches, and intimidating showering high school boys along the way, and he obtains a list of all the boys who have enrolled in school since the fall and tracks John "Baum" down. Gee, it"s almost like it was a bad idea for John to go to high school. Cameron, spotting Chrome Artie first, sends Morris into the office to pose as John. Morris doesn"t realize just what danger he"s in, although I don"t think it"s inaccurate to say that even if he did, he wouldn"t say no to Cameron. Chrome Artie compares Morris"s face to his file images of John, determines there"s no match, and moves on. John"s upset that Cameron could have been sacrificing Morris, and he also doesn"t want Sarah to find out that Chrome Artie got this close.
More images are revealed on Vick"s chip: turns out one of Derek"s men, Sayles, was following Mrs. T-888, and Vick followed him back to the safehouse, where he killed the resistance fighters. John flies a little too close to the sun hacking Vick"s chip, almost reactivating him (and alerting any other Terminators to John"s presence). Derek and Sarah"s mission to upload the virus to the traffic program fails when the program seems to repel the virus. John"s solution: stick Cameron"s brain-chip into the traffic system, let her muck it all up. And it works.
Finally, Sarah"s come to the conclusion that Derek killed Andy (his silence when she confronts him is confirmation enough). "You lie to me again, I"ll kill you," she says. Presumably, that"ll be after their meeting tomorrow morning with the guy who bought the Turk.
