Jeff Angelo
Jeff Angelo was the grandson of Mrs. Angelo and a resident of Leadworth. He apparently lived with his grandmother, and was implied to be viewing sites of a distasteful nature on the internet. As such, his laptop seemed to be an important item of his. The Doctor convinced him to send a virus to various alien experts, transmitting across the world to defeat Prisoner Zero. He was praised as a hero by the Doctor, who implied to Jeff that at least one of the alien experts would offer him a job. When Jeff asked why he was chosen by the Doctor, the Doctor replied that it was because it was his bedroom and advised he delete his internet history. (DW: The Eleventh Hour)
Later, when Amy was telling the Doctor that she was to be married, the Doctor asked if it was to "the good looking one", referencing Jeff, before Amy told him that it was Rory. (DW: Flesh and Stone)
