In Seymour's upcoming episode, titled "Good Lovin'," Colleen is arrested on prostitution charges and it's up to Peter and Jared Franklin (Breckin Meyer) to prove her methods are purely therapeutic. But when Jared's sexually demanding fling with the opposing DA renders him exhausted and useless, Peter must single-handedly confront his mother on the stand and divine her true motive.

The Hollywood Reporter has an exclusive clip from the episode, in which Seymour also locks lips with Heather Locklear, who joined the show this season as the new boss.

STORY: Jane Seymour on Returning to 'Franklin & Bash' and Kissing Heather Locklear

Seymour recently talked to THR about returning to the series.

"The surprise is this time I need [Franklin and Bash's] help because I've been arrested for prostitution," she explained. "It's a complete misunderstanding; [Colleen is] actually a sex surrogate."

Of the kiss with Locklear, Seymour adds, "Ultimately, I find out Rachel [Lockear's character] hasn't had sex for six years, and so I kiss her. I really can't tell you much more about the episode without spoiling it. I haven't seen it, but they tell me it's one of the funniest ones they've ever done."

Franklin & Bash airs at 9 p.m. Wednesdays on TNT. Watch the clip above.
