Nancy creeps around the bomb site and ducks behind a tent, but she's nicked, and Jack's army friend Algy turns on the floods and tells her to halt, guns everywhere.
In the Chula ship, Rose and Captain Jack are chatting about his history. Rose: "You used to be a Time Agent; now you're trying to con them?" Jack tells her that it's not about the money -- he found out they'd stolen two years of his memories (not to mention Vaughn was married to some bint with too much eyeliner). "Two years of my life. No idea what I did. Your friend over there" -- Jack nods to the Doctor, who's looking at him hard -- "...doesn't trust me. And for all I know, he's right not to." They head to the crash site.
Algy drags Nancy into a tent, where another soldier, by the name of Jenkins, is looking none too good. He waves it off for Algy, who tells him to keep an eye on Nancy, and has her handcuffed to the table. "No," she says firmly. "Not in here. Not with him." The scar on his hand, crosswise. Check. "You shouldn't have broken in here if you didn't want to stay," says Algy, lightly. Nancy protests, "You don't understand! Not with him." Algy blows her off and says that they're going to need to ask her some questions, but Nancy can't look away from Jenkins, and the other soldier with Algy finds her wire cutters. "Very professional," he says. "Little bit too professional. Didn't just drop in by accident, then, did you?" Nancy says that her little brother died on the site, and that she's investigating it. Algy tells the other men to check the perimeter in case there are other breaches or accomplices. He makes to leave after them, but she calls out again: "Please! Listen, you can't leave me here." Algy ignores her, and tells Jenkins to watch her, and Jenkins replies: "Yes, Mummy." Check. Algy's like, "No you didn't!" but Jenkins -- who's clearly in much discomfort -- apologizes for the brain-freeze. "Look," Nancy tries again, "lock me up, fine. But not here. Please, anywhere but here!" Algy isn't having it, and leaves. Jenkins apologizes, and tells her that she'll be okay, even as she's pulling and shaking on the cuffs, trying to get free. Jenkins pants and sweats and chokes and asks what her deal is, and she begs again to be let go: "You've got a scar on the back of your hand. And you feel like you're gonna be sick, like something's forcing its way up your throat. I know because I've seen it before." Her voice gets desperate. Jenkins is getting nervous, too: "What's happening to me?" Nancy tells him that he isn't going to be himself much longer: "You won't even remember you. And unless you let me go, it's gonna happen to me, too. Please. What's your mother's name?" Jenkins tells her, but when Nancy asks for his wife's name, his children's name -- nothing. "What's your name?" Nancy asks, and he can't even talk anymore. But he doesn't know it. Nancy: "Please. Let me go. It's too late for you -- I'm sorry -- but please, let me go." She's nearly crying. Jenkins's face begins to contort, nastily, and he calls out for "Mummy," and Nancy just looks away, eyes shut tight, as he changes.
Captain Jack spots Algy on duty at the bomb site, and Rose assumes that she's meant to distract him. "I've gotten to know Algy quite well since I've been in town," Jack says. "Trust me. You're not his type." Over his shoulder, Captain Jack calls in a flirting tone, "Don't wait up!" The Doctor, seeing Rose's confusion, smiles lightly: "Relax, he's a fifty-first century guy. He's just a bit more flexible when it comes to dancing." Just how? The Doctor adds, "By his time, you lot have spread out across half the galaxy." She refuses to put the pieces together. "So many species..." the Doctor grins, "...so little time...." And Rose is a little wigged. "What, that's what we do when we get out there? That's our mission? We seek new life, and..." The Doctor nods, sniggering: "Dance." Which, whatever. Unchain sex from procreation and it turns into art. Ask the '70s.
