The new season of "Criminal Minds" is set to premiere this fall, but CBS has been teasing the fans with tidbits of police drama from the series' latest season.

Over Twitter, the network revealed a new still of Thomas Gibson as Aaron Hotchner, the series' lead character. In the still, Hotchner glares into the camera with an angry expression on his face, alongside the caption, "Hotch faces his toughest case yet: 3rd graders."

As well, Enstarz details some new footage that was recently released in a Vine. The footage showed Gibson and co-star Shemar Moore chasing after children- presumably, the third graders in question.

Breathecast recently stumbled upon a piece of the script for an upcoming "Criminal Minds" episode, that details not only the dialogue for Shemar Moore's character, Morgan, and also the hilarious writing process that creates with the show's scripts.

Here's the dialogue from the leaked script pages, along with a note from the screenwriter.

"Morgan: That shirt you're wearing is a fly shirt. [Or whatever awesome saying Shemar comes up with that doesn't sound like a white, nerdy writer wrote it]"

Given the presence of Doug Adams (another character on the series) in the leaked script page, fans are now speculating that Adams, who at this point is not a regular character, may have an increased presence in future seasons of "Criminal Minds."

In other "Criminal Minds" news, Christian Today reports that C.S. Lee, best known for his role as Masuka and Showtime's "Dexter," will appearing in the next season of "Criminal Minds." According to their reports, Lee's character will be a villainous one, with a penchant for locking people in sheds.

Lee's character on "Dexter" was a comical one, so it'll be a treat to see Lee take on a role that's completely different from what we're used to.
