Colville (Revenge of the Cybermen)
From Tardis Wiki, the free Doctor Who reference
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 inquired about his brother, Crewmaster Colville, who was doing a tour on Nerva. While he was told his brother was fine, this was a lie Stevenson instructed Warner to tell Colville, as per his order, to keep quiet the fact Crewmaster Colville had been among those killed by the Cybermats.
