Adam is back on Floor 139, touching his head, as Cathica comes down the corridor. She doesn't notice him, being very absorbed in this whole "thinking" thing she's just discovered, and she heads to the elevator and enters the override code, boarding.
"If we create a climate of fear," the Editor explains to the now-manacled Doctor and Rose, "then it's easy to keep the borders closed. It's just a matter of emphasis: the right word in the right broadcast, repeated often enough, can...destabilize an economy, invent an enemy, change a vote..." Got it, got it. Don't lose track. Rose: "So, all the people on Earth are, like, slaves." Got it. "That's an interesting point," the Editor admits. "Is a slave a slave if he doesn't know he's enslaved?" The Doctor, Kierkegaard, even Plato are like, "Dude, yes. We've been over this." The Editor was looking for a philosophical debate, so the self-evident and snappy "Yes" disappoints him: "Is that all I'm going to get?" The Doctor gives a great "Fuckin' yes!" response, and the Editor laughs: "You're no fun." The Doctor offers to show the Editor just how fun he is, if he'll unshackle them. The Editor: "Oh, he's tough, isn't he." The Editor begs them to admit that it's a great, foolproof system, but Rose tells him that nothing on this scale could possibly stay hidden -- that somebody somewhere must have noticed. The Editor admits that this does happen, from time to time, but explains that since the computer and chips allow him to see inside your brain, it's easy to find "the smallest doubt, and crush it."
As the Editor speaks, Cathica arrives in the elevator and comes out into Floor 500.
Elsewhere, Adam enters an empty broadcasting room.
"... And then they just carry on, living their life [sic], strutting about downstairs and all over the surface of the Earth, like they're so individual," says the Editor. The Doctor sees Cathica in the corner of his eye, where she's entered quietly and stayed out of sight. "When of course they're not! They're just cattle. In that respect, the Jagrafess hasn't changed a thing." Got it, got it. Rose: "What about you? You're not a Jagra...uh... a --" The Doctor says it for her: "-- Jagrafess. You're not a Jagrafess. You're human." The Editor tells her straight up that "simply being human" doesn't pay very well. Ah, capitalism. "But you couldn't have done this all on your own!" Rose protests. "No, I represent a consortium of banks -- money prefers a long-term investment. Also, the Jagrafess needed a little hand to...um...install himself." Cathica spots it on the ceiling, as the Doctor agrees that anything that large might need some help. "What's his life span?" asks the Doctor. Three thousand years. "That's one hell of a metabolism generating all that heat -- that's why Satellite Five's so hot. You pump it out of the creature, channel it downstairs. Jagrafess stays cool, stays alive. Satellite Five's one great big life-support system." He's not really talking to the Editor at all; he's giving Cathica the information.
