The TARDIS materializes inside Amy and Rory's house, and the Doctor bursts into their bedroom, waking them up. In a great lather the Doctor tells them that the world is endangered and that they need to save the planet now. Suddenly, he realises that they have no idea what he's on about, and goes to leave since he's obviously arrived before any of these Earth-shattering events are happening. After Amy questions his decision, he tells them not to worry, and that everything is safe. While saying this, some clips from "Dinosaurs on a Spaceship" are shown, with the Doctor, the Ponds, and others, all facing peril. The Doctor then wishes them a good night's sleep, and flies away. Unable to go back to sleep after this interlude of foreboding doom from the Doctor, the couple are seen in bed staring at the ceiling while Rory remarks "I really hate it when he does that".
