And down on Earth, everybody lives. The sleepers awaken, step back, look around. They stare up at the ship.
"You killed them!" screams Alex, his words once more his own. "What do you think, big fella? Are they dead?" Caliban stutters: "We...allow them to live." The Doctor laughs at him. "You've no choice! I mean, that's all blood control is. Cheap bit of voodoo. Scares the pants off you, but that's as far as it goes. It's like hypnosis, you can hypnotize someone to walk like a chicken or sing like Elvis, but you can't hypnotize them to death. Survival instinct's too strong." Caliban, "Sycorax Rock" Caliban, gets defensive. "Blood control was just one form of conquest. I can summon the Armada and take this world by force." He's just a kid. They're just kids with too much firepower and not a hugely strong work ethic. What lies behind their power is lies; blood control is nothing. The pilot fish that accompany them seem more powerful. The Doctor: "Yeah, you could do that. Of course you could. But why? Look at these people." He gestures to the humans, speaking passionately: "These human beings. Consider their potential. From the day they arrive on the planet and blinking step into the sun. There is more to see than can ever be seen. More to do than -- No, hold on...Sorry, that's The Lion King. But the point still stands." And the point is this: "O, wonder! How many goodly creatures are there here! How beauteous mankind is! O brave new world, that has such people in't!" (O wonder, that. Not "maiden" but "wonder"; all that divinity forgotten.) "Leave them alone!" Caliban's like, "Or what?" And the Doctor grabs a sword off another Sycorax, drops to the floor below the stairs and, holding the sword high before the TARDIS: "I challenge you." The Unkindness laughs. One might say unkindly.
"Oh, that struck a chord. Am I right that the sanctified rules of combat still apply?" Caliban approaches him, unsheathing his sword: "You stand as this world's champion." The Doctor shrugs out of his robe. "Thank you. I've no idea who I am, but you just summed me up." He is a champion god without a home, and so he has adopted one; again and always and forever, with the Estuary on his tongue. That's the kind of man he is. He tosses the robe to Rose, and asks Caliban if he's going to fuck around or get down to it -- "Or are you just a cranak pel casacree salvak?" (Whoa there! I didn't realize that was a bad thing!) They kneel, ceremonially, and Caliban looks into the Doctor's eyes. "For the planet?" The Doctor nods: "For the planet."
