Fans of Criminal Minds: Evolution have been speculating about the possible return of Dr. Spencer Reid, played by Matthew Gray Gubler, in the show's second season. Reid was notably absent in the Paramount+ reboot, with the explanation that he was working on another assignment with a different unit. However, the season 1 finale teased his potential return. In the final moments, a door opened and the scene went black, leaving viewers wondering who was about to walk in. Many fans took to Twitter to express their theory that it could be Reid. The speculation is fueled by Reid's popularity and the fact that his character would fit well in the reboot, given his expertise in profiling and his eidetic memory. However, Matthew Gray Gubler has not confirmed his return, and showrunner Erica Messer has hinted at scheduling conflicts that may prevent it. Until there is official confirmation, fans will have to wait for updates and revisit Reid in the original series.
