Thomas Gibson Shemar Moore Criminal Minds CBS

The BAU is about to lose its leader on “Criminal Minds,” but could someone else be back to take Hotch’s (Thomas Gibson) place?

Everyone remembers the heartbreak of finding out that Derek Morgan (Shemar Moore) was leaving the BAU and “Criminal Minds” all together back in March of 2016. Now, the show will suffer another major loss as Thomas Gibson exits due to an altercation with a writer on set.

Aaron Hotchner has been a fan favorite for years, but this isn’t the first time he’s had to step down as chief of the BAU. In Season 5, Hotch handed the position over to none other than Derek Morgan, while he dealt with being the target of a serial killer called The Reaper.

Given the new information that Hotch will likely have to step down again permanently, it makes sense to start wondering if Morgan will be lured back into the BAU lifestyle.

Moore’s exit from the series seemed to have more to do with growth and moving on from a show he’d been loyal to for 11 years than any behind-the-scenes drama. However, the actor’s recently uploaded — and quickly deleted — Instagram video alluding to Gibson’s recent firing has us wondering if something else was at play between the actors.

“I’ll just say this: I believe in karma,” Moore says. “Good things happen to good people. Honest people. Hard-working people. Humble people. People who believe in basic goodness … Treat people how you expect them to treat you. Celebrate yourself and celebrate your blessings, as you should, but just know that you’re not better than anybody.”

The cryptic video doesn’t call anyone out by name, but the meaning is plain — what goes around comes around.

We know that the cast of every TV show likes to pretend they’re all one, big, happy family on set. But, it seems like the relationship between Moore and Gibson on “Criminal Minds” was less than familial, if this call-out video is any indication. Now that Gibson is no longer part of the show, we have to wonder … will Shemar Moore be willing to return for Season 12?

While Moore made no comments about returning to the show, the door was left wide open for him to appear again after he exited. So, with that said, Hotch’s departure could mean big things for fans of Derek Morgan.

“Criminal Minds” returns Wednesday, Sept. 28, at 9 p.m. ET/PT on CBS.
