Jason Venezia
Jason Venezia was a human who worked on the SS Lucy Gray, when the last humans left Earth and tried to escape the solar flares. (GAME: Evacuation Earth)
He guarded the entrance of the ship, but was bored of his job. He rather liked to see the band Death by Solar Radiations on their last Earth gig than stopping people from entering the ship.
The Eleventh Doctor and Amy Pond gave him music, so that he wasn't bored anymore. Later Jason was working on the ship and Amy and the Doctor helped him again. (GAME: Evacuation Earth)
When the Doctor and Amy came back to the SS Lucy Gray centuries later the Doctor saw a holographic photo of Jason, revealing that his surname was Venezia. The photos were in a hallway together with a statue of Amy and the Doctor. (GAME: Return to Earth)
