Priestley spoke with the press about his experience on “Psych,” saying it was a bit like a reunion because he’d worked with so many of the actors before, including his fellow guest star Jennifer Finnigan (pictured with Priestley, above).

“I’ve always been a fan of [‘Psych’], so when they called me up and asked me if I wanted to do this episode … then they told me that Jennifer Finnigan was going to be playing my partner in this episode, I was even more excited by that because Jennifer and I have been very good friends for a very long time,” says Priestley. “I’ve always been a very big fan of her work. It was a wonderful confluence of things that made this a lot of fun for me and something that I was very happy and very eager to be a part of.”

“Psych” is known for its blink-and-you’ll-miss-them barrage of pop culture references peppering every episode, so we had to wonder if there would be any “90210” references in Priestley’s episode, which makes him laugh.

“No, no ‘90210’ references on the show. At this point in my life, that project is so quickly disappearing in the rearview mirror of my life. I tend to reference that as infrequently as possible,” says Priestley.

The episode, called “Neil Simon’s Lovers Retreat,” features Shawn (James Roday) and Jules (Maggie Lawson) on a romantic getaway, so Priestley only interacted with them out of the main cast. But that was enough of a challenge.

“The hardest part of working with James is keeping a straight face because he is a very, very funny man,” says Priestley. “So there are challenges inherent within that. But him and Maggie are both very professional and very prepared. You really have to show up on that set with all your material prepared and ready to go because as it is with television, everything moves very quickly.”

Look for more from our interview with Jason Priestley Wednesday night (Dec. 14) when the “Psych” midseason finale airs on USA at 10 p.m. ET/PT.
