I’m kind of loving Psych‘s love of all things ’80s and Brat Packish. The USA comedy has tapped Judd Nelson to guest star in an episode to air this winter. He’ll play a CDC researcher who specializes in a made-up Ebola-like ailment called Thornburg’s disease. In Psych‘s third season finale, Ally Sheedy was outed as the Ying Yang Killer. Who will they recruit next? Demi Moore as Shawn’s quirky aunt older sister? Got a better idea? Post it below!
