S5 E3: A top forensic psychiatrist, Dr. Greta Heints (Susanna Thompson), is found assaulted and bound in a crack house. She regains consciousness but doesn't seem too eager to help Benson (Mariska Hargitay) and Stabler (Christopher Meloni) find her assailant. Her husband says she got a call on the private patient line the night of the attack and then went out. Detectives Munch (Richard Belzer) and Fin (Ice-T) investigate Greta's case list and they are looking at a patient named Benny Edgar Ralsay (P.J. Marshall), also known as the duct tape rapist. He has an ankle bracelet and claims he was at home the night of the attack, but the detectives also discover he slips his surveillance by putting the bracelet on his cat. Benny says he has nothing but total respect for Dr. Heints, even though her unconventional method - regressing patients to their early childhood to reparent them - has some people, like Dr. Huang (B.D. Wong), a little concerned.
