In 2005, while in her aunt's house in Devon, Sally Sparrow tore off a piece of wallpaper, revealing a message from 1985 asking for help. After later finding a photograph with the Ninth Doctor asking to look through the wallpaper again, she found another message leading her to play a video recording of the Doctor in 1985; the Doctor communicating to Sally through already having the conversation from Sally's uncompleted Christmas homework.
The Doctor explained that the TARDIS had "burped" forward in time twenty years to this year and needed Sally's help. Sally's future self appeared, telling Sally to hit the TARDIS reset button to reach the Doctor. The Doctor told Sally to finish her homework detailing this conversation and the messages left to her first, which she did. Sally then piloted the TARDIS to the Doctor to rescue him.
