The Battlestar Galactica and Dollhouse alum will play Michael Hastings, a former co-worker of JJ's (A.J. Cook) from her unseen gig at the State Department in Season 6. Michael will help shed light on what happened to JJ during her time away from the BAU.
The news of Penikett's arrival first came out on the Instagram account of producer Rick Dunkle. "Battlestar BAU Crossover?" he wrote alongside a photo of Penikett and former Caprica star Esai Morales, who joined Criminal Minds earlier this season as the new section chief Mateo Cruz.
Criminal Minds airs Wednesdays at 9/8c on CBS.
