Larry Nightingale
Lawrence "Larry" Nightingale was a science-fiction nerd 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 Doctor and Martha.
Sally told him that his sister had gone on a trip when she had been transported to Hull in 1920 by the Weeping Angels. He 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, he met the Doctor and Martha in person. The final scene implied that they would persue a relationship, with the two holding hands as they entered the store. (DW:Blink)
