Actress Paget Brewster has responded to a viral theory about her character on the TV show Criminal Minds. In a TikTok video, a fan suggested that Brewster's character, Emily Prentiss, died in season 6. The theory proposed that Dr. Spencer Reid, played by Matthew Gray Gubler, had a mental breakdown and believed Prentiss was still alive. When the theory gained traction, it was shared on Twitter and Brewster responded with the word "Brilliant." Fans of the show found the theory intriguing and shared their opinions in the comments section. Some evidence from the show suggests that Prentiss' presence may have been in Reid's imagination. Reid's mother had schizophrenia and Reid himself experienced intense headaches in season 6. Prentiss' trajectory on the show also supports the theory, as she left and returned at various points. Although the character has since returned in Criminal Minds: Evolution, the theory has sparked speculation among fans.
