Criminal Minds (CBS)
Premieres: Wednesday, Sept. 25, 9/8c
Where We Left Off: The Replicator was revealed to be John Curtis, a disgruntled former associate of Strauss and Blake's. He killed Strauss and kidnapped Blake back to his lair, and ostensibly died in an explosion there after Rossi locked him in his booby-trapped room.
What's Next: A new boss! NYPD Blue and Caprica star Esai Morales joins the cast as Matt Cruz, filling in the section chief void left by Strauss. He has a professional history with JJ that will be explored throughout the season. Rossi and Reid will still be mourning the losses of their significant others, so don't expect anything new on the romance front. And keep an eye out for unsubs at large who may make a return — and The Reaper, as the show will revisit Haley's death. New guest stars include Camryn Manheim and David Anders.
