In the rocket, Toby Zed begins to laugh. Quietly and to himself. Nobody's quite as happy as Toby that they've gotten away alive. "Not all of us," grumbles Rose. "We're not out of it yet," notes Zach. "We're still the first people in history to fly away from a black hole." Toby checks the pull of the Pit: "Gravity funnel holding, sir. Always holding." In a vacuum gravity's a constant; black holes change things but let's stay with that idea for a sec.
"I accept that you exist," the Doctor grants Him. "I don't have to accept what you are, but your physical existence, I'll give you that." The Beast growls, and the Doctor takes a few steps toward It. "But I don't understand. I was expected down here. I was given a safe landing, and air. You need me for something. What for?" The Beast lunges, straining against His chains. "Have I got to...I dunno, beg an audience? Or is there a ritual? Some sort of incantation or summons or spell? All these things I don't believe in. Are they real?" (I said I wouldn't do this anymore, but: "Solsbury Hill" just came on shuffle. Computers are smarter than you and I. "Which connection I should cut.") The Beast just stares. "Speak to me! Tell me!" Words. The Beast is silent. "You won't talk. Or...you can't talk?" The Doctor talks to himself at length: "You spoke before. I heard your voice. An intelligent voice. No, more than that: brilliant! But, looking at you now, all I can see is Beast. The animal. Just the body. You're just the body, the physical form." The thing we share. It's us that give it power. "What's happened to your mind? Hmm? Where's it gone? Where's that intelligence?" And then he knows.
Toby Zed smiles. "Stats at 53, funnel status at 66.5, hull pressure constant. Smooth as we can, sir. All the way back home." Rose stares, not listening. No home, now. No time and no home. She's forgotten the big rule: the enemy's gate is down. Now, more than ever; now literally. As she speeds away; as Toby quirks his mouth. "Coordinates set for Planet Earth."
