The Criminal Minds series finale will also feature a couple of comebacks. "The Reaper" (C. Thomas Howell,) for instance, will be back again. The murderer has already been hunted down several times by the team and became the arch enemy of "Hotch" (Thomas Gibson) after he killed the agent's wife.

Will "Reaper's" return also bring back "Hotch"? Thomas Gibson left the show in 2016 following an argument with the producer. Fans would certainly be happy to see him again!
