"The Mentalist" Season 6 returns with Episode 13 on CBS on Mar. 9. Red John's revenge is set in motion, as the Blake Association is out to kill Patrick Jane (Simon Baker), Teresa Lisbon (Robin Tunney), Wayne Rigsby (Owain Yeoman), Grace Van Pelt (Amanda Righetti), Kimball Cho (Tim Kang), and others. Jane's new chapter could be a short one. Fans are speculating this could be the final season of Bruno Heller's crime series.

Owain Yeoman has already made his final bow on Twitter. He is done filming Rigsby scenes. Amanda is also leaving The Mentalist. Season 6 could be the final season, fans suspect in online forum sites. After all, Bruno Heller will be busy with "Gotham City," a new series on FOX. But nothing is official yet. CBS has not announced a renewal or cancellation.

J.J. LaRoche (Pruitt Taylor Vince), an important recurring character in the Red John investigation, appears in The Mentalist Season 6, Episode 13. Rigsby and Van Pelt come to him for help with regards to the Blake Association kill chain.

Jisbon (Jane and Lisbon) shippers are hoping for a happy ending. But Lisbon will be dating someone new in The Mentalist Season 6. His name is FBI Special Agent Marcus Pike, portrayed by Pedro Pascal. Bruno Heller said this relationship will allow Lisbon "to be able to step away from Jane and see herself for herself."

Heller had kept the Red John arc going for six years. Some mentalistas are having a hard time seeing Patrick Jane in a new chapter without chasing the big bad guy. But Heller had expressed in previous interviews the series is about Jane being a "mentalist." Yet, unless The Mentalist Season 7 is official, many fans are betting the end of Red John is the end of the series.

Watch The Mentalist Season 6, Episode 13 online or on demand via CBS media for viewers who couldn't catch "Black Helicopters" in its premiere telecast.
