Directed By David Platt
A woman (Cynthia Nixon) who switches between five different personalities is suspected of harming her daughter. The investigation is met with initial resistance from her psychiatrist (Bronson Pinchot). When the woman's sister (Laura Allen) is released from jail, their parents are found murdered the next day and the two of them become the prime suspects.
- Bitch in Sheep's Clothing: The multiple personality act on Janis's part turns out to be just that.
- Family Theme Naming: Janis and her sister Cass are named after Janis Joplin and "Mama Cass" Elliot, both female inductees of the Rock and Roll Hall of Fame.
- Patched Together from the Headlines: The episode begins as a Gender Flip of the Billy Milligan rapes before it's revealed that it's also ripped from the headlines of the Menendez brother murders, in which two brothers killed their allegedly violent and sexually abusive parents.
- Pyrrhic Victory: Janis manages to obtain a "not guilty" verdict and is committed to a mental institution thanks to faking her multiple personalities, but the detectives arrest Cass as a co-conspirator, to their mutual shock.
