Nathan (Planet of the Dead)

Nathan was a passenger on Bus 200 when it travelled through a wormhole. He was on the top deck when it went through, but rushed down the stairs before it was torn apart by the wormhole's power. He said he was unemployed and he was going to stay at home watching TV. When he was returned safely home, the Tenth Doctor recommended him to Captain Erisa Magambo for a position in UNIT because he was good in a crisis. (TV: Planet of the Dead)
