1. A Danger to Himself and Others

Complete story — includes the ending

Picking up on the day after Season 3 ended, Romero disposes of Bob Paris' body in the bay. With Norman missing, Norma and Dylan worry about his well being. A farmer discovers an unstable Norman, resulting in him being admitted to a psychiatric unit. Meanwhile, Dylan goes to Portland to be by Emma's bedside after her lung transplant, while Norma attempts to have Norman discharged from the institution. The psychiatric doctor refuses to let Norman leave until after a 48-hour observation period, and chastises Norma for never taking Norman to a doctor for his frequent blackouts. Desperate, Norma returns to Pineview Mental Hospital hoping to have Norman admitted as soon as possible and encounters a psychiatrist, Dr. Edwards. Since she doesn't have insurance, Norma asks Romero to marry her so she can use his, but he rebuffs her. Elsewhere, Emma's estranged mother, Audrey, attempts to make contact, but Emma's father turns her away. As Audrey seeks help from Norman, "Mother" strangles her to death with her own scarf.
