The potential return of Derek Morgan in "Criminal Minds: Evolution" season 2 seems increasingly unlikely due to Shemar Moore's ongoing commitment to "S.W.A.T." season 8. As "S.W.A.T." has been renewed, Moore's availability to reprise his beloved role as Derek Morgan is restricted, posing a significant challenge for the showrunners. 

The reboot of "Criminal Minds," now airing on Paramount+ with a grittier tone, continues the legacy of the original procedural while delving into complex new storylines. One such development includes bringing back characters from the past, such as Jason Gideon's ex-wife, enriching the narrative tapestry.

However, the return of other fan-favorite characters like Matt Simmons and Spencer Reid remains in limbo. This uncertainty is compounded by logistical issues, as "Criminal Minds: Evolution" confronts the stark realities of limited resources and reduced manpower. These constraints necessitate creative solutions, potentially involving new characters or revisiting other former team members to bolster the Behavioral Analysis Unit (BAU). 

Despite these challenges, the show must address a formidable new adversary—a network of UnSub serial killers that emerged during the pandemic. Fans eager for a dose of psychological thrill can stream the latest season on Paramount+, where the original cast faces these unprecedented threats.
