Larry Nightingale

Lawrence "Larry" Nightingale was a science fiction fan who worked in a video-store with Sally Sparrow.

Biography
He first met Sally Sparrow (a friend of his sister, Kathy Nightingale) when he was walking naked around his sister's flat. He knew of the easter-eggs on 17 DVDs containing the Tenth Doctor and Martha.

Sally told him that his sister had gone on a trip when she had in fact been transported to Hull in 1920 by the Weeping Angels. Kathy got married to Ben Wainwright, lived a full life, and died in 1987. Unbeknownst to him, Larry had a niece and nephews older than he was.

Larry and Sally found and trapped the Weeping Angels and returned the TARDIS to the Doctor and Martha. Sally and Larry began running the video-store together. The next year, they met the Doctor and Martha in person. They returned to the store holding hands. (DW: Blink)
