This document provides brief descriptions of two characters, Charles and Fred. Charles is an Irish-born psychiatrist evaluator who carries disposable gloves, a medical kit, and a satchel and speaks formally. Fred is a security guard wearing a plain white uniform with no company insignia who is equipped with a taser and reinforced handcuffs. The document also mentions that the voices of characters will be recorded in a studio, sound effects will likely be Foley, and music/ambient sound will probably be an existing asset.
