John is still entertaining Riley -- relax, they're fully clothed -- when the rest of the Connor Crew comes home, and Sarah gives John the gears about bringing Riley home when he just met her today. He whines a whole lot about wondering when it's his time to start living his life, when I thought the whole point of his haircut was that he was going to be less of a crybaby.
The next day at work, Sarah follows Greenway's nemesis into a restricted area of the plant. He catches her where she's not supposed to be, but she invents a cover story about looking for the supply area, so he puts her to work in the waste-barrel part of the plant. Unfortunately, she gets "crapped up" -- exposed to radiation. Somehow. She should have zipped her Hazmat suit up tighter.
It's morning at the Connor Compound, and Riley has inadvertently spent the night. Since she woke up earlier than John, she's made him a Lego robot, which freaks him out a little more obviously than he probably wants. He does allow Riley the option of calling him sometime, provided the first words out of her mouth when she calls him are the date. That's just the way it is, he tells her. If she's smart, she'll be too freaked out to call him back. I have a feeling, though, that she won't be smart.
Over at the power plant, Sarah's finding out she's not "crapped up" at all, that the positive reading on the scanner must have been a "hiccup," according to the plant honcho.
Looks like Charley and his wife are moving out of their house, I guess because the killer robots from the future know where they live? Luckily for Charley, Ellison is on hand to see them off with a copy of the Bible, which should be nice protection from the searing pain of the laser beams.
At the power plant, Greenway's conducting the final test, only he's a lot less concerned about the coolant than he had been previously. Since he doesn't have the giant surgery scar on his arm that he used to, it could be because, as Derek discovers (Sarah calls him, opening the conversation by stating the date, just as John instructed Riley to do), the real Carl Greenway is hanging from a noose at his house. Whoever's conducting the test, that ain't Greenway. But the plant? She's online.
So the robot version of Greenway starts opening valves. Cameron doesn't react initially, because she's thinking about what to do. "Since when do you do that?" asks Sarah, but there's no time, as Cameron has to go fix a water valve.
