George was a human who worked in the town Scraptown and later on the SS Lucy Gray, when the last humans left Earth and tried to escape the solar flares.
The Eleventh Doctor and Amy Pond met him in front of Scraptown and helped him to sort out some machine parts. Later George worked on the ship and, since Amy and the Eleventh Doctor needed his help, they did him some favours. George was a chaotic person. He forgot were he put things and didn't tidy up his room. The Doctor and Amy helped him to find his stuff and tidy the room. (GAME: Evacuation Earth)
