Taking place shortly after the TARDIS dematerialised from Leadworth, Amy asks the Eleventh Doctor many questions without pausing: how does the TARDIS retain its air supply? Why did he label a time machine "police box"? Where are the other windows which are on the exterior of the TARDIS? What is a police box and is the Doctor a policeman? Has he seen his haircut? Does he ever need to change the bulb on top the TARDIS? She also thinks the box is made of wood and his bow tie is a cry for help.The Doctor answers most of these questions. Amy asks again if he's an alien. The Doctor says that, from his perspective, she's the alien. Amy wonders if the Doctor is a space squid or a tiny slug zipped in a human suit, but the Doctor dismisses her theories, stating he's as human as he appears. Amy admits she's done with her questions, but the Doctor tells her she's just begun; he throws a switch on the TARDIS console, opens the door and shows her outer space.When Amy says it looks like special effects in a studio, the Doctor proves it's real by pushing her out of the TARDIS.
