Complete story — includes the ending
Norman is anxious to be arrested, fearing that he will see "Mother" and she will intervene. He is interrogated, and given his medication, but "Mother" forces him to vomit it out and takes full control of him. "Mother" blames Madeleine for Sam's murder and says Norman confessed to take the fall for her. Dylan gets a lawyer and explains that Norman is not a criminal nor a bad person - he is mentally ill and needs a mental institution. Emma's mother's body is also found and identified from the lake, confirming Dylan's suspicion about Norman killing her. Romero returns to the Bates' property and finds Chick, who has set up his writing desk in the house. Chick is killed by Romero after mocking him and the entire situation. Sam's body is found next, and Norman, with "Mother" still in control, is charged with three murders.
