The Mentalist is currently on a brief midseason hiatus, but when it returns in January, Wayne Rigsby and Grace Van Pelt will make an appearance once more.

Jane (Simon Baker) and Lisbon (Robin Tunney) will return on Jan. 5 with their news post-Red John team in "White Lines," but once the faux psychic puts to bed the murder of several DEA agents and heads off on a date, Rigsby (Owain Yeoman) and Van Pelt (Amanda Righetti) will pop up with their own case in "The Golden Hammer."

As the FBI tries to solve the death of a cartographer who may have uncovered a spy ring before his death, the married couple will be hard on the heels of a conspiracy.

The last time viewers saw the former CBI agents was during "My Blue Heaven." In a very brief clip, Rigsby and Van Pelt quickly explained that, in the two years since the dissolution of the CBI, they had started their own private security company and were town the proud parents of a young baby (see video below).

However, the pair is slated to depart the series sometime this season. Now that FBI Agents Dennis Abbott (Rockmond Dunbar) and Kim Fischer (Emily Swallow) have essentially replaced them, the only remaining mystery is to how the duo will exit the show.

"I have not shot the final episode yet, there's a few episodes that I'm not filming, like partway through the season," Righetti told PopSugar at the end of November. "They haven't really decided yet what episode 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."

The Mentalist airs Sundays at 10 p.m. ET on CBS.
