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. (TV: The Time of Angels)
