Criminal Minds (CBS)
Airs: Wednesday, May 22 at 9/8c
The members of the BAU will at long last come face to face with their season-long nemesis The Replicator when one of them becomes a victim. Mark Hamill guest-stars in the two-hour episode, but details about his role are being kept under wraps. (Is he The Replicator?) Hotch's brother Sean (Eric Johnson) and his girlfriend Beth (Bellamy Young) will return for the first hour, which takes place in New York and ends with a Replicator cliff-hanger. Speaking of cliff-hangers, the season will yet again close with one — and with someone's future hanging in the balance.
