It is acquired by recording writing on a wall in the Male Ward.
"The harder I try to escape, the further I get into this god awful place. Like fighting a tar pit. They've been torturing people in the basement, and by method. Written on the wall- "FINGERS FIRST. THEN BALLS. THEN TONGUE." Somebody's managing the torture, instructing them."
The writing on the wall refers to Richard Trager and his torture methods.
