He also revealed that the Chameleon will test Rossi and the team’s patience.
Last season, Criminal Minds set up the character’s run, which will span roughly half of Season 15, with “four or five” episodes.
That is what Ozark’s Michael Mosley (he played Pastor Mason) shared when teasing his time on the veteran drama’s final season to TVLine.
Due to the Chameleon changing up his appearance, Mosley had to don various disguises and “run around like a maniac,” but noted that being with the show in the end “was an honor.”
