Criminal Minds‘ JJ is due to get a devastating blast from the past — and it will come in the form of Tahmoh Penikett.
As first revealed by Instagram photos shared by producer Rick Dunkle, the Battlestar Galactica/Dollhouse alum will appear in Episode 200 of the CBS crime drama, and now TVLine can reveal exclusive details.
Penikett will play Michael Hastings, someone with whom JJ worked during her off-camera Season 6 stint at the State Department. And when he resurfaces, let’s just say that it is not happy to see me.
As previously reported, Criminal Minds‘ milestone episode will shed light on JJ’s time away from the BAU, addressing questions first raised by the introduction of Esai Morales as new section chief Mateo Cruz. As showrunner Erica Messer told me last week, “The mystery of what happened to JJ is very much answered…. A lot of things happened to her professionally and personally that we never knew about.”
At the time TVLine spoke with Messer, she had just screened a producers’ cut of Episode 200, which she said “looks like a movie. It’s beautiful, the production values are insane.” Told partly in flashback, it also features an encore by series vet Paget Brewster, as Prentiss.

Penikett’s other TV credits include Supernatural, Continuum, Castle and The CW’s upcoming Star-Crossed. (And yes, this episode will “reunite” Helo and Adama.)
Criminal Minds airs its 199th episode this Wednesday at 9/8c. Do not miss the final seconds.
