David Lancel "Dave" Underwood was a member of Torchwood One. He sat with Pippa and Ianto Jones on the bus to the Away Day. He claimed not to wear clothes on the weekend and to be afraid of olives.
On the Away Day, he helped care for a wounded member of Torchwood after he was injured by a weapon. He later attempted to save Pippa after she too was injured, but she died. He did not seem too bothered on the bus back (AUDIO: Through the Ruins) and it was rumoured that everybody had been retconned but Ianto. (AUDIO: Uprising)
