Patrick Jane's (Simon Baker) 10-year hunt for the killer of his wife and daughter finally comes to an end as the identity of Red John is finally revealed. Does it mean the show is nearing its end or is it just a mysterious turn?

The popular American mystery crime drama series, "The Mentalist," has finally revealed Red John's identity. The Mentalist has teased its fans for more than six seasons with the identity of the serial killer, who killed Patrick Jane's wife and daughter. In Sunday's episode "The Great Red Dragon," Jane finally concludes that Red John is none other than the CBI director, Gale Bertram (Michael Gaston).

The story picks up from the  "Fire and Brimstone" episode where Jane gathers all possible suspects of Red John at his home. These suspects included Bret Stiles (Malcolm McDowell), Ray Haffner (Reed Diamond), Thomas McAllister (Xander Berkeley), Reede Smith (Drew Powell) and Gale Bertram (Michael Gaston). With the biggest clue he had got on the Red John case, Jane asks each suspect to show his left arm, looking for the three dots tattoo. But the story takes a mild turn as Jane is surprised to find a similar tattoo on the arms of McAllister, Smith, and Bertram. The episode ends with an explosion in Jane's house with Teresa Lisbon (Robin Tunney) rushing toward the house.

"The Great Red Dragon" episode starts with Teresa investigating the house, finding Smith still alive and in the process getting shot in a cross fire. Jane is found unconscious and the other Red John suspects including Stiles, Haffner, and McAllister are presumed dead.  With one other survivor besides Jane and Smith, Bertram is shown as Red John.

While Jane is still in the hospital Bertram tries to kill him but fails in his attempt. Bertram escapes with the help of Oscar and a bag full of money and supplies he had stashed in a storage facility.

Also, agent Cho (Tim Kang), Rigsby (Owain Yeoman) and Van Pelt (Amanda Righetti) find a flash drive containing coded messages.

The latest episode also reveals Red John's deep connections within the law organization that runs with the "Tiger, Tiger" code message. A new cast FBI supervisor Dennis Abbott (Rockmond Dunbar) makes an entry, shuts down the organization and releases all associates from active duties to investigate the Blake Association conspiracy and the Red John case.

In an interview with TV Guide, Jordan Harper, who wrote "The Great Red Dragon," revealed that there was more to come.

"The audience is going to come out of this episode with a lot of questions, but they just are going to have to wait a week and then see Red John, and I promise their minds will be blown - their socks blown off," Harper said.
