The Mentalist will be getting a visit from the under-eight set after the midseason hiatus.

Wayne Rigsby's (Owain Yeoman) young son will be making another appearance in episode 15, according to TV Line. Benjamin, who was born to Sarah Harrigan in season 4, was last seen during this season's "Wedding In Red."

Despite this recent appearance, the two-year, post-Red John time jump means that the CBS series needs to recast an older version of the little Rigsby. TV Line claims that The Mentalist is looking for a boy between the ages of four and five to take on the part.

Now married to Grace Van Pelt (Amanda Righetti), Rigsby currently has another young child by the name of Maddy. Currently out of the picture for several episodes, the small family is lined up for a midseason exit.

With Patrick Jane (Simon Baker), Teresa Lisbon (Robin Tunney), and Kimball Cho (Tim Kang) relocated to the FBI, Rigsby and Van Pelt have started their own security agency and have been seen very little in the last few episodes. Despite this, the couple will be hot on the trail of a conspiracy in the upcoming installment "The Golden Hammer."

As for their pair's impending exit, even Righetti claims she is unsure of the ultimate plan. However, it is probably safe to say that they will feature in episode 15 alongside Rigsby's son.

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