The Mentalist - Season 7 - Dylan Baker and Christine Adams to Guest

Thanks to Champagne010 for the heads up

FBI Agent Dennis Abbott's (Rockmond Dunbar) past will come back to haunt him in a major way over a three-episode arc that also features guest stars Dylan Baker as a DEA agent "who knows a bit too much about Abbott's past" and Christine Adams as Abbott's wife. "We're going to meet Abbott's wife, and we're going to learn about some dark things in his past," Szentgyorgyi says. "His wife gets an opportunity in Washington, D.C. She lives in Austin but she's been given a chance to take on a big job in Washington, D.C., and that creates various complications."
