Colville (Revenge of the Cybermen)

Colville was a crewmember on Pluto Earth Flight One Five, who responded when Warner contacted the ship from Nerva Beacon. Warner informed him that Nerva was in quarantine because of a plague infection and their stopover had been transferred to Ganymede Beacon. Colville enquired about his brother, Crewmaster Colville, who was doing a tour on Nerva. Crewmaster Colville was among those who had been killed by the Cybermats; however, as per his order, Stevenson instructed Warner to tell his brother that he was fine. (TV: Revenge of the Cybermen)
