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 seems to be an important item of his. The Doctor got 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, The Doctor said it was because it was his bedroom. (DW: The Eleventh Hour)

Jeff is considered good looking by Amy and the Doctor but is perhaps not the sharpest knife in the drawer. It is also unknown why Jeff didn't want the Doctor to take his laptop off him.
