The actor will return as Derek Morgan for the episode, in which “Morgan brings the BAU a lead in the case against serial killer and escaped convict Mr. Scratch, who has wreaked havoc on the team all season,” according to a press release from CBS.
Moore is an original cast member who starred on the crime drama from 2005 to 2016 and appeared in 251 episodes. He left the show last March after 11 seasons. Criminal Minds addressed the departure by having Morgan bid adieu to the bureau to spend more time with his family. Moore’s credits since his departure include Justice League vs. Teen Titans and The Bounce Back.
