Will Matthew Gray Gubler's Reid Finally Come Back In Criminal Minds: Evolution Season 2

Much has been said about

. It's still unclear where Reid is while the BAU hunted down Sicarius and his network of serial killers, however, it has been made clear that he remains a member of Emily Prentiss' team, he's just busy with other matters. This makes it fairly easy to bring him back if Gubler finally decides to partake in the Paramount+ project.

In recent months, however, Gubler has been publicly spotted with a couple of his old Criminal Minds co-stars.

Before his meet-up with Vangsness, he and Dave Rossi actor, Joe Mantegna also crossed paths and even had dinner. There was no mention of having any discussions about Reid's comeback in season 2. However, it's difficult to believe that the matter didn't even come up, especially with Mantegna being fully aware of the clamor for Gubler's character to return.

Whether Reid will be in season 2 is still uncertain.

However, between still being firmly a part of the BAU and Gubler's great relationship with his old cast mates, it won't be difficult to bring him back into the Paramount+ show. In any case, there's no rush for the actor to decide on the matter since the dual WGA and SAG-AFTRA strikes have delayed season 2 indefinitely.
