Later, Emma visits Norman and informs him that she is his real mother, and that Mrs. Bates was her sister, who adopted Norman as an infant while Emma was institutionalized. She reveals that she was the real murderer, having killed anybody who tried to harm her son. In response, Norman strikes her in the head with a shovel, killing her. He then carries the body upstairs to Mother's room, and begins talking to himself in her voice, signifying that Norman's “Mother” personality has once again taken control of his mind.
