Guard (The Pandorica Opens)

The Guard was a Human guard at the Stormcage Containment Facility, in 5145. On his first day on the job, River Song managed to elude him and escape, using Hallucinogenic lipstick. By the time reinforcements arrived, he was in Song's cell pointing a gun at a stick figure of the prisoner drawn on the wall, thinking it to be the real thing. (DW: The Pandorica Opens)
