that she is not to blame for the deaths, but she is frequently visited by visions of Harris, who claims to have killed her friends and pressures Cynthia to commit suicide, saying that the only way to stop anyone from dying is to take her own life and join him and the other Unity Fields' victims in the afterlife. A male and female patient who are lovers are later killed by the blades of an industrial fan in the utility room of the hospital, which Cynthia also attributes to Harris. She believes Harris has come back from the dead to kill those around her. Ralph Pesco, a troubled masochist patient with a tendency for violent outbursts, becomes enamored with Cynthia; finding himself on the edge after the deaths of his fellow members in the group, he knocks down a policeman who was watching him, and goes to talk to Cynthia, who was spending the night with Dr. Karmen in order to feel safe.

There, during an apparent episode of psychosis and violence, he commits suicide by stabbing himself multiple times in the abdomen. Awakening from sedation after the incident, Cynthia finds Harris sitting in her room, calling her his "love child," and urging her to commit suicide.

Alex realizes that Cynthia's suicide is the ultimate goal for Berrisford, so he orders the nurses to call the police and Detective Wasserman, who was investigating what happened at Unity Fields before the suicides began. Alex confronts Cynthia, insisting her visions of Harris are not real. He is surprised by Berrisford from behind, who knocks him out and takes Cynthia with him. Dr. Karmen wakes up and pulls the hospital's emergency alarm, which elicits chaos. Cynthia goes to the rooftop, where Alex finds her standing on the ledge, with Berrisford at her side, encouraging her to
