The Doctor herds everybody into the church and then heads for Rory and Amy's place. The DL appears in the van, wearing a spacesuit. "Friends? Is that the right word for the people you acquire? Friends are people you stay in touch with. Your friends never see you again once they've grown up. The old man prefers the company of the young, does he not?" The Doctor doesn't let it show, on his face.
The Doctor arrives at the house, which is littered with olds. They're raking and hoeing at the walls and the doors. Inside, Amy wakes up in Rory's arm. "I carried you. I'm afraid you may experience some bruising," he says sweetly, apologetically. When she sits up, the music swells and he takes a pair of handy scissors to his ponytail. It's totally dumb but it doesn't last long. The Doctor appears at their feet, and Amy I guess goes into labor, and the zombies attack. "They're scared," says the Doctor. "Fear generates savagery."
Rory is hit with eyeball spray, and goes slowly to dust. "Look after our baby," he says, and he's gone. Amy goes very quiet and very still, and unmoving she whispers, "Save him. You save everyone. You always do. It's what you do." She's counting on it. She's always counted on it. He shakes his head. He keeps showing her, over and over. A few tears, down her cheek:
"Then what is the point of you?"
The story can end now.
"This is the dream. Definitely, this one. Now, if we die here, we wake up, yeah?" Or they just die. "Either way, this is my only chance of seeing him again. This is the dream. Because if this is real life, I don't want it. I don't want it." The old folks let them pass, without attacking. Maybe because it's a dream, or maybe because they know what she is planning. The Doctor gives her the keys to the van, clasping her hand, ready to where she leads. "I didn't know... I honestly didn't, till right now. I just want him. I love Rory, and I never told him, but now he's gone."
The Doctor looks the DL in the eye, gets into the van with her. And she drives it, faster and faster, and steers into the house. And they die.
"You chose this world," the DL smiles. "Well done. You got it right. And with only seconds left!" He turns up the heat, since they've won the game. "I hope you've enjoyed your little fictions. It all came out of your imagination, so I'll leave you to ponder on that." Rory wakes, hands covered in ice, and she slowly throws her frozen self upon him. They turn their faces to the Doctor, like sunflowers, asking him what happens next.
