During the events of Delirium: Photo of Gioia (1987) played by Karl Zinny
Mark watches Gioia with his telescope as a photo shoot is going on. He calls her and tells her a series of crude comments before she hangs up. That night, he calls Gioia and tells her Kim has been murdered and her body is in the pool. After Kim's body is found, Mark is questioned by Inspector Corsi and tells him the murderer had blonde hair. He continues to spy on Gioia and his family's maid tells him his father called, but he tells her to tell him he is not in. He then calls Gioia and tells her the murderer did her a favor by murdering Kim as the issue with her on the cover is going to sell out. He sees Gioia come home with Alex Worth and kiss and he points a pellet gun at Alex and mimics shooting him then laughs. Dr. Lorenzi visits Mark and tells him his inability to walk is all in his head, and later when Mark finishes placing a bouquet on the gravestone of his former fiance, he drives home. After more people connected to Gioia are murdered, Mark calls her and asks her how it feels to be surrounded by death. He sees Tony attacking Gioia and shoots him in the leg. He then visits Gioia in the hospital and after telling her she is beautiful and asking her if he can visit her, he tells her not to forget him.
