Summary
Criminal Minds: Evolutioncan always bring back Spencer Reid and Derek Morgan, but their return will work under one specific storyline, showrunner Erica Messer reveals. After a short broadcasting break, the FBI’s Behavioral Analysis Unit (BAU) is back on the small screen via the Paramount+ revival. Emily Prentiss has a solid team around her as they chase the mystery of Gold Star while ensuring that Elias Voit stays in prison. As great as theCriminal Minds: Evolutioncastis, there’s alwayshope that Shemar Moore and Matthew Gray Gubler eventually return as their respective charactersto the franchise.
When asked about this, Messer tellsTV Linethat thedoor is always open for Derek, Reid, and even Daniel Henney’s Matt Simmons to appear. However, she reveals that their comebacks will only work if it’s due to a personal matter and not a professional one. Read her full quote below:

At this point, what could bring anybody back [Reid and Matt included] would be an emotional draw versus any case work.
Messer’s Criminal Minds: Evolution Update Makes Bringing Back Morgan And Reid Trickier
Both Moore And Gubler Are Open To Return In Criminal Minds: Evolution
Considering past comments about Reid and Simmons' whereabouts,Messer’s comments are discouraging. As established inCriminal Minds: Evolutionseason 1 by the late Deputy Director Bailey, the pair is working on a case elsewhere, hence why they couldn’t join the BAU in taking down Sicarius and his serial killer network. Despite this, they remain members of Prentiss' team, which means they can return anytime. This new update makes it seem like there areno concrete plans for bringing Reid and Simmons back just because their separate cases are done. Instead, it should be via a new narrative.
Despite this, Moore said that he is open to returning, adding that the only reason he hasn’t appeared inCriminal Minds: Evolutionis because he hasn’t gotten an invitation from the people behind the revival.

This reasoning fits with Morgan’s situation better.Moore’s character left Criminal Mindsto focus on his family. He has returned a couple of times during some rough patches for his old team, but he has never fully come back for a case in a professional sense. He has effectively walked away from the job, knowing how dangerous it is for him and his family. Despite this, Moore said that he is open to returning, adding that the only reason he hasn’t appeared inCriminal Minds: Evolutionis because he hasn’t gotten an invitation from the people behind the revival.
JJ’s Criminal Minds: Evolution Season 2 Struggle Sets Up The Ugliest Franchise Character Exit
Criminal Minds: Evolution season 2 introduces a new issue with JJ that could result in the franchise’s ugliest way to write a chracter out.
Regardless of the specifics, perhaps they can return via the already confirmedCriminal Minds: Evolutionseason 3. No release date has been set for it, considering that season 2 is still in the middle of airing, but perhaps by then, the schedules of Moore, Gubler, and Simmons have all been cleared up for them to participate. It would be a shame for the revival to end with no sighting for any of them.
