The Series Finale Of ‘Criminal Minds’—Here's Everything You Should Know

As fans of the show know, the team is set to face off with fictional serial killer Everett Lynch, also known as The Chameleon, played by Michael Mosely, one last time. “The Chameleon is back and he’s more chameleon-y than ever,” Matthew, 39, revealed to TV Line. “He’s worse than ever, he’s got a vendetta with Rossi, and he’s taking people’s faces left and right. Rossi, though, has a new theory to pursue, and … well, I don’t want to give too much away.”

Matthew also spoke about possible character exits. However, he insisted that viewers would be satisfied with the outcome and seemingly made a reference to spinoffs in the near future.

“The last two episodes, as all 324 episodes, have been written really beautifully and thoughtfully, and they’re teeing up, I think, something really special,” the 68 Killer star explained.

He added, “It’s a really beautiful ending, but they’re setting up a lot of different avenues of exploration for these heroes that we’ve come to love and have in our homes for so many years. It’s kind of interesting to see how it all will eventually shake out.

Matthew also revealed that fans could also expect to see some familiar faces including, Jayne Atkinson, Beth Riesgraf, and C. Thomas Howell. “They all feel like they’re there presently in every episode because they had such a big impact on the series,” Matthew explained. “When I’m playing Reid, Jayne’s always in the back of my head, and Beth Riesgraf is always in the back of my head, and Foyet even.

The Life After Beth actor noted, “It’s a really cool finale, a really special one that does a nice little job of closing out this, for lack of a better term, insanely long run, this special thing we’ve been so blessed to be a part of.”
