Lady programmer tries to open the Archive with a hand-activated panel like we saw in the spike ritual a hundred years ago, and it causes the Controller pain: "Archive Six is out of bounds." The Controller goes a bit nuts now, scared and unable to move: "Archive Six is out of bounds. No one may enter Archive Six. Return to work." You'd think she was protecting the Archon, his secret transmats -- not hiding things from Him. Genius, this. She falls back into herself, muttering. "Return to work. Inform all staff: solar flares in delta point seven. 19...20...." That's how long until she's free again.
Jack attaches the Compact Laser Deluxe to the Defabricator and creates a gun from it, and possibly a Sopranos reference for himself, and says farewell to the ladies: "Got myself a gun! Well, ladies. The pleasure was all mine...which is the only thing that matters, in the end." He exits, finding himself on Floor 299, and immediately uses his wrist tech thing to find the Doctor's two hearts. Good little Companion.
The Doctor shows Lynda the world, literally, on what looks like a very similar observation deck. The whole planet is ugly and mottled, with a few patches of light on the surface. "It's always been like that," Lynda says. "Ever since I was born." She points out "The Great Atlantic Smog Storm," which has been going on for twenty years and the safety and breathing index on which the news determines for everyone. The Doctor: "So, the population just sits there? Half the world's too fat, half the world's too thin, and you lot just watch telly?" Stop yelling at me, Davies. "Ten thousand channels, all beaming down from here," Lynda says, and the Doctor goes on a wobbly that the human race is sheep and whatever, and then interrupts himself to ask whether they've still got "that program where three people have to live with a bear," and they agree that they love the show (Bear With Me), especially the celebrity edition where the bear got in the bath. The cruel mistress that is adult ADHD swings him right back around on how history's gone wrong, "again," and that the Fourth Great and Bountiful Human Empire is still neither "Great" nor "Bountiful." "Last time I was here, I put it right," he says, and Lynda corrects him: "No, but that's when it first went wrong. A hundred years ago, like you said. All the news channels, they just shut down overnight.... There was nothing left in their place. No information. The whole planet just froze. The government, the economy, they collapsed. That was the start of it. One hundred years of hell." Ouch. The Doctor swallows his watchmaking diploma with a mighty effort, looking down on this ruined place: "I made this world."
