Wayne Rigsby and Grace Van Pelt are back for season 6 of 'The Mentalist' which is due to return in January after the "Red John" story arc ended.

Rigsby (Owain Yeoman) is a senior agent of the California Bureau of Investigation whose talents as an arson investigator proved to be very valuable. Meanwhile, Van Pelt (Amanda Righetti) was the team's baby who usually worked with Rigsby in several cases. She is known for her skills behind the computer in the headquarters although she wanted to be on the field with the agents every time.

The last viewers saw the couple was during the episode "My Blue Heaven" where they said that they already have their own security company after the CBI was disbanded. They also have a baby together.

When 'The Mentalist' season 6 airs on Jan. 5, Patrick Jane (Simon Baker) and Teresa Lisbon (Robin Tunney) will have their hands full in investigating the murders of DEA agents, while also going on a separate dates on the side.

The skills of Rigsby and Van Pelt, meanwhile, will be highlighted during the episode "The Golden Hammer." The couple will try to make sense of the conspiracy involving the death of a cartographer who unwittingly stumbled upon a spy ring.

Don't get used to Rigsby and Van Pelt, however, since their roles are already redundant with the presence of FBI agents Kim Fischer (Emily Swallow) and Dennis Abbott (Rockmond Dunbar). It's not yet clear, however, how the writers of the series plan on giving them an explosive exit.

According to PopSugar, Reghetti said that the writers haven't decided yet how "they're going to exit the character or, if they have, they haven't shared it with me...I don't know if they really know to be honest."

"I think they're still trying to figuring out the best exit strategy for the character," she added.
