The Mentalist is officially saying goodbye to Wayne Rigsby and Grace Van Pelt.
"It's a very exciting opportunity, I think, for fans to say their goodbyes to two beloved characters," Yeoman tells TVGuide.com about the episode. "It's a very dynamic episode. I think our show pushed the envelope. ... It felt very different than what we've done."
Adds Yeoman: "I'll be shedding a little tear on Sunday saying goodbye to my long-term buddy Wayne Rigsby."
But will Rigsby and Van Pelt's ending be a happy one? At the end of last week's episode, Van Pelt was kidnapped by an unknown person who's targeting former CBI agents. "The whole of the episode becomes this action-packed quest for Rigsby to quite literally save the life of his wife," Yeoman teases. "The stakes couldn't be higher for my character."
Yeoman says the episode will show viewers a different side of Rigsby. "It's a very exciting episode for us," he says. "There's lots of twists and turns, and there's a bit of a badass side to Rigsby. Who knew?"
News of the their departures first surfaced in August, and Righetti confirmed the exits in November. The actress has since booked guest-starring gigs on Chicago Fire and its spin-off Chicago P.D., while Yeoman says he's exploring developing his own projects.
The Mentalist airs Sundays at 10/9c on CBS.
