In the Criminal Minds episode ‘Surface Tension’, while the BAU investigates the death of homeless man found with a bizarre hieroglyph under his armpit, Dr. Spencer Reid (Matthew Gray Gubler) visits his mother Diana. Criminal Minds fans haven’t seen Reid’s mother since 2008, when Reid was trying to find his father in Las Vegas. Now, after witnessing his mother’s paranoia, Reid decides to take her home with him.
Diana Reid is portrayed by Jane Lynch. She’s known for her roles on Angel from Hell (deviant angel Amy), Glee (Sue Sylvester), Two and a Half Men (Charlie’s therapist Dr. Linda Freeman), and The L Word (Joyce Wischnia), among many others. Lynch is also well recognized for her roles in the films The 40-Year-Old Virgin (Paula) and Role Models (Sweeny). She also sings (see below). Criminal Minds airs Wednesdays at 9pm on CBS.
