Shiiipping

Billy Shipton flirts with Sally Sparrow after showing her the police box that was found at an abandoned house where a bunch of cars were also abandoned over the years. After accidentally calling herself Sally Shipton, she gives him her number and runs off. After she's gone, he turns around and stone angels have surrounded the box. He blinks...

...And wakes up in 1969. He is immediately met by The Doctor and Martha Jones. The Doctor explains that the Weeping Angels send people back in time to feed off the energy of the days never lived. He then tells him that he needs him to take a message to Sally.

Back in 2007, Sally returns a few seconds later to where she left Billy, only to find him gone. Her cell phone rings. It's Billy. She asks where he is. She turns up in a hospital, where she finds a very much older Billy lying in a bed. They talk briefly about his life. He married a girl named Sally. They laugh about her being Sally Shipton. He tells her about how he got into video publishing and she deduces that he put the easter egg of The Doctor on the DVDs. He tells her that he often thought about coming to see her again earlier, but The Doctor told him that it would destroy 2/3s of the universe and that he would only see her again on the day he dies.
