Bob (The Time of Angels)

Bob, is a Cleric, who was a member of Father Octavian's mission to track down the last Weeping Angel which was on the Byzantium when it crashed. During the expedition, in the "Maze of the Dead", Bob was killed by a Weeping Angel. However, The Eleventh Doctor, could still communicate with Bob via Father Octavian's communication device. Because the Angels lacked a voice and because it wanted to torment its victims it copied Bob's consciousness and used him has a mouthpiece to talk to the Doctor. While it sounded calm the words clearly showed the psychopathy of the angels, and how they didn't care about killing innocent men.

The Angel consious confirmed the Doctor's suspision that the Byzantian Crash was a rescue mission on the Angel's part and while its brethrin were still feeding on the ship's tempral core to heal it was coming for the Doctor and the others and it would enjoy killing tham.
