A 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 make the guard think 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 was later killed when the Byzantium was destroyed by the Weeping Angels. (TV: The Time of Angels)
