Lisbon sits with Roy Carmen, the CBI psychologist assigned to her since the encounter with Red John. Roy signed off on Jane after one session, and will do the same with Lisbon but he believes she has something she wants to tell him. A new case ends their session, William McTeer, a serial child rapist who Lisbon put away back in her San Francisco P.D. days with Bosco is found murdered in an alley. Forensics comes back with the prints on the gun, and they belong to Lisbon! Minelli takes Lisbon and the team off the case and puts Bosco on it instead. Unable to recall what she did the night of the murder, Lisbon fails the polygraph test and is suspended. Jane hypnotizes her in hopes that she'll remember, but when that fails, he begins to put the pieces together of what really happened. Together Jane and Lisbon set a trap for the Killer, CBI psychologist Roy Carmen. At the office, Lisbon suffers a nervous breakdown. Worried for her mental state, Minelli sends Roy Carmen to her apartment to check on her. Pretending she's suicidal, Lisbon gets Roy to replay the night of the murder and Roy slips on a detail that only the killer would have known. Jane deduces that Dr. Carmen had been putting lorazapam in the coffee Lisbon was drinking during their sessions and lifted her prints from the mug to transfer to the murder weapon in order to frame her for McTeer's murder.
