Criminal Minds: Evolution season 2’s explanation for Will’s absence has been revealed. The flagship crime procedural show was rebranded as Evolution when it transitioned to Paramount+ in 2022 with much of the main cast intact after being cancelled by CBS. Criminal Minds: Evolution season 2, which is the seventeenth season of the show overall, will feature the return of many of those actors, including Paget Brewster, Joe Mantegna, A.J. Cook, Kirsten Vangsness, and Aisha Tyler, though notable recurring character Will LaMontagne Jr. (Josh Taylor) – the husband of Cook’s JJ Jareau – will not be returning.
