Barclay (Planet of the Dead)

Barclay was a passenger on Bus 200 when it travelled through a wormhole. He was going to Tina's, who, as he commented to the Tenth Doctor, was not yet his girlfriend. When he was returned safely home, the Doctor recommended him to Captain Erisa Magambo for a position in UNIT because he was good with engines. (DW: Planet of the Dead)
