2. The Impossible Witness — The victim's identical twin appears and claims to have seen the real killer through visions. His unusual knowledge makes him both a potential witness and a suspect.
3. The False Suspect — The twin investigates Pendler, tracks him down, and survives his attack. Although physical evidence implicates Pendler, his behavior does not fit the established killer profile.
4. Visions Under Hypnosis — Recurring dreams lead the twin to Dr. Battera and hypnosis. The clarified vision connects Pendler's attack with mismatched shoes and Tannerson's presence.
