On the season finale of The Mentalist, Patrick Jane will meet a new love interest.

On the May 3 episode of this CBS hit, meanwhile, Teresa Lisbon will come across a former flame: TV Guide reports that Kenny Johnson (The Shield, Sons of Anarchy) will guest star as Greg Taybeck, Lisbon's high school squeeze who gets involved in an investigation.

"She ran away [from that relationship] to find a different life," Executive Producer Bruno Heller tells the site. "So, she stops and has to reassess her life and look at the paths not taken. Her boyfriend has kids, and she doesn't. So, how does she feel about that?"

Heller adds that the episode will center around the "joys and regrets" of realizing where one is in life.

The Mentalist returns with a new installment on April 26.
