Security guard (The Time of Angels)
From Tardis Wiki, the free Doctor Who reference
The Security Guard was a member of Alistair's security staff on board the Byzantium Starliner. He was walking confusedly around a forest setting dazed, this was done by River Song so that she could get into the ship. He was later found by Alistair who wiped lipstick from his face, revealing it to be the calling card of River Song. It was unknown if her was killed when the Byzantium crashed.
