With the help of Miles Dyson's widow, Sarah tracks down a former Cyberdyne intern whose photograph appears in surveillance photos taken by the resistance fighters they found dead last episode. Sarah figures they were a "Skynet hunting party," so she tracks down the intern herself, and he's now a dorky cell phone salesman with a hobby that involves building a chess-playing computer that may or may not be on the cusp of artificial intelligence. She charms her way into a couple of dates and then torches his house. Which beats the time he went on Blind Date and a little pop-up graphic implied he was impotent, but still.
Meanwhile, Cameron and John begin classes, with John warning Cameron not to be a freak. This proves to be more than she can handle; she tells another girl that yes, that dress does make you look fat, and then makes friends with another girl who goes and throws herself off the roof of the school a couple hours later. It probably wasn't Cameron's fault, but she stops John from intervening. Sarah thinks that was the right decision, but John wants to know why they're bothering to save humanity from the robots if this is the way they're going to act.
Special agent Ellison is following the Connor Crew through the murders of Enrique and the resistance fighters, as we build the "weird evidence makes authority figure wonder if maybe Sarah isn't crazy" storyline.
And Chrome Artie tracks down a scientist and gives him some crazy skin-growing formula that he hadn't been able to get just right. It's a literal blood bath for Artie, who emerges a lot fleshier and creepier than his robot version. Science guy, do you need those eyes? Because I think I'm just going to help myself.
A classroom full of scientists -- the sweater-vests and pipes letting us know these are old-timey scientists -- write incomprehensible formulae on a blackboard and discuss science-y things as Sarah voiceovers that she became obsessed with scientists while she was in the mental hospital. Specifically nuclear scientists, the ones who invented The Bomb. "Oppenheimer, Heisenberg, Fermi, Teller. Pioneers, geniuses, all." Suddenly, Sarah's in the midst of the scientists, with her gun out and ready to kill these beautiful minds. She wants to know why these "fathers of our destruction" couldn't stop what they were doing, and if she had the chance, would she have stopped them? None of the scientists is paying any attention to her, and she shoots several times, killing them all. But they just get up again, and encircle her. And then they aren't scientists at all, but a ring of fleshless Terminators. She fires her gun again, but it has no effect. And then all the Terminators simultaneously raise their weapons, and shoot, which is when Sarah wakes up. She's on her bed, surrounded by documents and photographs.
John walks in with a cup of coffee for her, and he says, "You look like hell," which is not true now, and has not been true thus far in the series. She explains that there are newspaper clippings, surveillance photos, bank records, and pamphlets from every high-tech company in the state. "I even think I saw the deeds to city hall in there." She says the resistance guys weren't sent back to be a support group: "They're a Skynet hunting party." She can't make heads or tails of all the info, but there's one document that seems like a good place to start: a Cyberdyne employee list. "She's not going to be happy to see you," says John. "She never is," says Sarah wryly. He asks if she wants him to come along, and she says he's got his own job to do, a big one. At that moment, Cameron walks past in the hall, wearing nothing but bra and panties. Sarah takes a moment to reflect on the gratuitous cheesecake. Really, they're lucky she had any clothes on.
In the kitchen, Cameron, now fully clothed, is robotically putting on makeup, and John jokes that she's getting pretty good at it, but since it's not brain surgery, it'd be odd if an advanced cybernetic intelligence couldn't do handle a stick of eyeliner. Cameron replies that brain surgery would require a much sharper stick of eyeliner. John rolls his eyes.
Sarah walks in and notes that it's "much better" when Cameron wears clothes, which is a matter of opinion, and then starts going over the big job that Cameron's got to do, unfolding a diagram on a piece of paper: "Okay, six ways in, six ways out. The front opens to the street here. Security's minimal. Two armed guards in the morning, four in the afternoon. And if anything goes wrong, there's a parking lot here." Planning a raid on some computer research lab? Nope. Just going to high school. John says he can handle it, and kisses his mother goodbye. "We can handle it," says Cameron, which is a relief to Sarah. "Don't you kiss me," she warns Cameron, who heads out the door. "Or anyone else," calls Sarah. Aw, the first day of school. That brings back memories; heading to school with my futuristic cyborg killing-machine bodyguard.
