The gate to the gallery opens just as hand-bots beam in. Amy -- the awesome, older Amy -- goes charging at them, kicking and slicing and twirling and slicing some more. "Go! I've got your back!" she shouts. The young'uns rush into the gallery. A hand-bot anesthetizes Amy. She goes down. Rory whacks the hand-bot over the head with the Mona Lisa. The canvas tears. For some reason, this completely knocks the bot out of commission. When old Amy catches up, she's momentarily paralyzed by the sight of Rory tenderly carrying her younger self into the TARDIS. Old Amy runs for the TARDIS, but the Doctor shuts the door in her face. "I'm sorry," he says. It turns out he lied to her. The paradox of having two Amys on the TARDIS would be too much. Rory is distraught. "She'll die!" The Doctor argues that she won't ever have existed. But she's out there now, pounding on the door, begging to be let in. He tells Rory to choose which Amy he wants and puts his hand on the lock.
Amy and Rory put their hands up to the window pane at the top of the door. She saw the way he looked at her other self. She'd forgotten how much he loved her, she says. Rory starts dissolving into tears. "I'm sorry, I can't do this." He turns the lock on the door. Is he locking it or unlocking it? I can't really tell. "Don't let me in," Amy says. She wants go in, wants to fight for her life, but she loves Rory and she's giving him back his lifetime with her younger self. They say their "I love you"s and Rory slowly backs away from the door.
Hand-bots surround Amy outside the TARDIS. "Do not be alarmed; this is a kindness," they say. She turns to face them. She asks the Interface to show her an image of Earth. "Did I ever tell you about this boy I met there, who pretended to be in a band?" She doesn't fight when a hand-bot touches her cheek. She crumples to the floor and closes her eyes just as the world around her fades to white.
In the TARDIS, Amy's boys watch over her while she sleeps. Rory asks if the Doctor knew all along they couldn't save both of them, but the Doctor is enigmatic as usual. Amy stirs. "Where is she?" she asks, looking around. The Doctor frowns a bit and then the episode just... sort of ends there. Was the editor anesthetized by a hand-bot? It seemed a bit abrupt, didn't it? Maybe the ending got compressed in a timestream.
