The Mentalist: Season 2, Episode 3

2 - 3: Red Badge

Lisbon is still attending counselling after five weeks and is upset that the psychiatrist won't sign her off yet. The CBI receives an anonymous tip about a murder, and the team finds the dead body of a criminal from Lisbon's past - a child molester Lisbon had arrested years ago together with Sam Bosco. Lisbon is quickly named the prime suspect after her gun is discovered to be the murder weapon and she is unable to recall the night of the murder. When a lie detector test is done, it is shown she has strong feelings of deception. She then goes into depression and cannot understand why she does not remember what happened that night. Patrick attempts to hypnotize her to make her remember and realizes that she cannot because she has been drugged. Patrick and Lisbon then put on a show in the office that makes Lisbon seem crazy and the murderer is revealed to be her Pyschatrist, who was paid to do this by a defendant whom Lisbon was to testify against.
