Christian (The Time of Angels)
From Tardis Wiki, the free Doctor Who reference
Christian was a Cleric, and a member of Father Octavian's mission to track down the last Weeping Angel, which was onboard the Byzantium Starliner when it crashed. During the expedition in the Maze of the Dead, he was seen to carry the gravity globe which was later destroyed by The Doctor who shot it. He was also the first to encounter and be killed by a Weeping Angel. The Angel used his voice to lure his fellow Cleric, Angelo. (DW: The Time of Angels)
