It is located in the back left corner of a room just before pushing aside a storage unit in the Vocational Block.
I conducted another interview with your patient, Dennis, this afternoon and have to agree with your suspicions. In the course of a forty minute interview, I had a wide exposure to all four of Dennis' expressed personalities, (as near as I could tell two brothers, their father, and their grandfather.) They seem primarily concerned with some life-threatening flood, though there was little consistency between the event having already happened or threatening imminent arrival.
The clarity of his delusion, and performative nature of the personalities' expression certainly suggests malingering. I admittedly fall in the Furstenburg camp of categorical skepticism of the Dissociative Personality Disorder. But Dennis's case seems clearly invented by an attention-seeking patient, more likely symptoms of gross narcissism and obsessive compulsive disorder. Continue with shock therapy.
Sincerely, Dr. Wolfram"
