Lacuna! We've hacked the mainframe. I imagine in that time we've gotten some superego tight-ass crap from Cathica, some maddening Tao of Pooh crap from the Doctor, and a whole lotta nothing from Rose, who doesn't have a lot to do this week. "Satellite Five: pipes and plumbing. Look at the layout." Cathica wigs on the Doctor for disregarding access to "the archive, the news, the stock exchange," and focusing on the pipes and stuff. They (with Excellent help from Rose) notice that all the cooling ducts and ice filters are set at "high" and are focused on moving heat down: away from Floor 500. "Something up there is generating tons and tons of heat," says the Doctor, and Rose says she feels like she's missing out on a party: "It's all going on upstairs. Fancy a trip?" Cathica points out that they need the lift key, and the Doctor scoffs some more well-meaning circa-1992 hacker crap: "Keys are just codes, and I've got the codes right here." He keys in "override 215.9," and replies to Cathica's worried questions, "Someone up there likes me," staring at us/the Editor through a camera lens. The Editor laughs to himself.
Commercial. Adam sits in the surgery, feeling his forehead. Tamsin cheers that it was painless and scar-free, and Adam asks how to activate it. Tamsin: "It's a personal choice. Some people whistle -- I know one man who triggers it with 'Oh, Danny Boy.'" Adam looks at her. I know, creepy, right? Like eXistenZ, only with your forehead instead of your rear end. "But you're set on default for now. That's a click of the fingers." "Click" is British for "Snap." Just like how roosters in Spain go "Co-co-rico," in Britain all the cereal goes "Click, Crackle, Pop," or when somebody crosses the harshness threshold everybody goes, "Oh, click!"
Rose and the Doctor get on the lift up to Floor 500, and they ask Cathica to come with them, but God only knows why, considering her sucky nature. What is that Arthur O'Shaughnessy thing Willy Wonka spits at Veruca? (Or was it Violet?) "We are the music makers, and we are the dreamers of dreams." I always think that when people act that way. I would come off like a twat if I said that to somebody, but Gene Wilder pulled it off tolerable well. Due to rocking. Very Ninth Doctor, that. So the Doctor and Rose are all, "Come with us! Come with us!" and Cathica's like, "'Fraid not!" And finally the Doctor, of course, is like, "Cool! Suck it!" and Cathica tells them not to mention her name or involve her in their trouble, and takes off. In the elevator, the Doctor sums up: "That's her gone. Adam's given up. Looks like it's just you and me." Rose nods. "Good," she agrees, and he takes her hand as the doors close.
