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 in Criminal Minds: Evolution season 1 by the late Deputy Director Bailey, the pair is working on a case elsewhere, hence why they couldn't the BAU in taking down Sicarius and his serial killer network. Despite this, they remain of Prentiss' team, which means they can return anytime. This new update makes it seem like there are no 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 in Criminal Minds: Evolution is 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 Minds to 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 in Criminal Minds: Evolution is because he hasn't gotten an invitation from the people behind the revival.

Regardless of the specifics, perhaps they can return via the already confirmed Criminal Minds: Evolution season 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.
