"With only two days before a man is executed, the FBI and Jane attempt to solve a cold case and prove the man is innocent," reads the Mentalist 6x17 episode synopsis on TV.com. In the past episodes, FBI Agent Dennis Abbott (Rockmond Dunbar) has allowed Jane to do what he wants. What is the mentalista game this week?

Pedro Pascal (of "Graceland" and "Homeland") re-appears in this episode as FBI Special Agent Marcus Pike. Incidentally, Pascal also currently portrays Oberyn Martell in the HBO hit series, "Game of Thrones." The Mentalist Season 6, Episode 17 cements the dating status of Pike and Teresa Lisbon (Robin Tunney).

Meanwhile, CBS has not announced a renewal for The Mentalist. Simon Baker was a guest on Ellen DeGeneres' show two weeks ago. They talked about The Mentalist Season 6 and the possibility that there will be no Season 7. Watch this video on YouTube for more details.

Many, if not all of The Mentalist fans will not be surprised should there be no The Mentalist Season 7. After the death of Red John, the series was never the same. It did not help that Red John turned out be someone so inconsistent with previously given clues.

For Jisbon shippers, the question now is whether Jane and Lisbon will end up together? Watch the sneak preview of this week's new episode. Spoiler alert, though, Lisbon and Pike will continue to date for a couple more episodes.

The Mentalist creator Bruno Heller is currently working on "Gotham," a DC Comics universe adaptation. This upcoming series will be distributed by Warner Bros. Television.

If there is no The Mentalist Season 7, why did Amanda Righetti and Owain Yeoman (who play Grace Van Pelt and Wayne Rigsby, respectively) have to exit the series? Yeoman on his Twitter page did not elaborate on the reasons, but said he will miss Rigsby.
