YMMV / Castle S 8 E 3 PH Dead

• Complete Monster: Dr. Barbara Lillstrom is a professor at Hudson University hired by the US Navy to recreate the 1971 Stanford Prison Experiment. Lillstrom would trick many college students into becoming test subjects for her experiments, imprisoning them for prolonged periods of time as she subjects them to mental and psychological torture. When two of her subjects, Peter Garber and Emily, escape her prison, Emily has a mental breakdown and murders Peter as a result of Lillstrom's actions, who even attempts to subject Richard Castle and his daughter, Alexis, to the same torture to hide her own role in Peter's death. Arrested by Kate Beckett, Lillstrom reveals Peter's sexual relationship with Dean Feller to save herself when Beckett threatens to reveal her inhumane experiment if she doesn't provide any information.
