It only took four years, but Joe Mantegna finally got his Criminal Minds wish.

"I've been campaigning to meet [Rossi's] ex-wives since we've established it in the third season," Mantegna tells "I've even campaigned for an episode where all three show up. How diverse would they be? I didn't want it to be like, you go to a play and they have a shotgun hanging over the fireplace. Somebody better grab that shotgun and use it by Act 3. I laid that in there with the producers about having these three ex-wives for so long: 'I think it's time we addressed that.'"
