One day, while Hope is out, an orderly feeds the residents dog food, and taunts Ethel by slowly eating a chocolate bar in front of her. Ethel snaps, and kills the orderly by hanging him with a cord, an act witnessed by Edgar. A lieutenant is called in to investigate the death, and leaves after questioning Ethel. Edgar tells Ethel that he will keep quiet about what she did, in exchange for her desserts. Ethel tries to poison Edgar, and when that fails, she resorts to stabbing him with four knives.After another visit from the lieutenant, Hope catches Ethel eating a bag of pretzels, and tries to confiscate them, prompting Ethel to bash her head in. Ethel proceeds to murder the remaining resident a man who believed he was an insect and one of the institution doctors when he drops by to see why his calls to the halfway house have not been getting through. Ethel then dances with a dog and a knife in the houses backyard, and when the lieutenant returns, she answers door, and laughs crazily as she states, Welcome to Bartholomew House. Im Hope Bartholomew, and I hope youll be very happy here ........
