Pete takes on the whole room, welcoming everybody. Some dude, horrifically, goes, "I thought you liked them young!" Yick. Not at the birthday party, dude. Rose's ears perk up, and she follows the sound of Pete's voice around to the staircase where he's standing; the Doctor follows. Pete thanks them for coming, makes the "thirty-ninth" joke again and adds a "trust me on this." But he's not unloving: "Without any further ado...here she is, the birthday girl. My lovely wife, Jackie Tyler." Rose strains to see her, and she comes down looking like a Mob wife, and everybody cheers and takes pictures. Rose just stares up. "Now, I'm not giving a speech," Jackie begins her speech. "That's what my parties are famous for: no work, no politics, just a few good mates and plenty of black-market whisky!" The crowd laughs hearty, and she spots a guest: "Pardon me, Mr. President!" she laughs. "So, yeah! Get on with it -- enjoy, enjoy." More cheers. I don't know British history as far as blue laws, so I don't know if this is a seriously bizarre alternate-universe thing or if it makes more sense than I think, because it seems to come out of nowhere. Come to think of it, though, it's not really any different from the military curfews or the airships, in that it's jury-rigged and never explained in any way, because this isn't alternate history, or the butterfly effect: it's just different. Alien. I like that. No reason at all. Peter takes his wife's hand and leads her down the stairs to the crowd, and the Doctor quietly cautions Rose once again: "You can't stay. Even if there was [sic] some way of telling them." Rose blows him off: "'Course I can't. I've still got my mum at home, my real mum. I couldn't just leave her, could I. It's just...they've got each other. Mum's got no one." The Doctor sighs: "She's got you! Those two haven't!" He laments the fact of humans and their foibles, because he's stressing hard. "Rose!" Jackie calls out. "There's my little girl!" The Yorkie comes pottering up, and Jackie takes her in her arms and does that "Good girl" talk people do to tiny dogs. Rose stares, and the Doctor starts laughing at the expression on her face, but straightens up after a look.
Mr. Crane walks outside the factory, PA announcing that the Platoon is "now boarding. Platoon zero-L-two boarding." Crane tells a staffer to stop staring at the Cybermen now rolling out, and his wording is interesting: "I'm told they're the future. Ain't technology wonderful?" Lumic checks in, and Crane tells him that they're just about ready to go. "Prepare the factory," Lumic tells him, and Crane sees his airship in the sky. "Now, send them forth, old friend," the old coot adds. "Let the good work begin."
