Security guard (The Time of Angels)

The Security Guard was a member of Alistair's security staff on board the Byzantium Starliner. When River Song infiltrated the ship, she used her hallucinogenic lipstick to fool the guard into thinking he was in a forest. He was later found by Alistair who wiped lipstick from his face, revealing it to be the calling card of River Song. He is thought to be killed when the Weeping Angel crashed the Byzantium. (DW: The Time of Angels) Although with the Angels never exsisting after they fell into the crack it is unknown if anyone survived the crash.
