And this clears up the lingering doubt I had about Riley actually being from the future: here she is as some filthy waif rummaging through people's things in one of the resistance's underground bunkers. There's Jesse, spotting her and tracking her down. Jesse brushes the hair off her face. "You're a pretty girl," she says. Like Riley's a parrot.

Eileen and Sarah pull up at a Slipstream trailer in the middle of nowhere. Sarah asks if Abraham is going to be cool with this. "Abraham doesn't live here. I do," says Eileen, adding that if Sarah's interested in Abraham, she's going to want to see this. They go inside, and the walls are covered with the same pictures the guy at the UFO conference had. Sarah drove all this way for this?

After the commercial break, Sarah has already figured out that "Abraham is a pseudonym." No, he put his own name on the blog that reveals military secrets. "Alan Park" is his real name, and he graduated from MIT specializing in Lidar, which is "light detection and ranging," which Sarah already knows, and its primary application is in robots. And then they have some tea and talk about the solitude of the desert, and how Eileen loves the solitude, most of the time.

Then it's back to business, with Eileen showing Sarah a map displaying drone sightings, and Abraham sightings. She points one out that's the most recent. "Then that's where we'll start," says Sarah.

Oh no! It's one of those deserted, windswept alleys that attract bright electrical balls that deposit humans or Terminators. In this case, it's Riley and Jesse. And then, having scored clothes, they're in a hotel room where Riley kind of oversells the skittish-waif-who's-never-seen-towels-before. And I realize Riley was filthy when Jesse found her, but she couldn't have at least WASHED before she went back to the past? But then we wouldn't get the dramatic shower scene with all the dirt and grime running off Riley down the drain. And then Jesse brushing Riley's hair and tucking Riley into bed. So in the present day Riley's helping John scrape the wallpaper off the walls and listening to him talk about how this wallpaper is his mom's subconscious way of keeping him a kid, and he goes to pull a flake of paper out of her hair and she recoils and he sees she's hiding a bruise on her left temple. He demands to know who did it to her, but she wants him to drop it, and he asks if it was her stepfather: "I'll kick his ass!" says John, and oddly enough the laugh track didn't kick in at that point. Riley runs off, telling John to leave it alone.
