As the production team shoots the 10^th season of 'Criminal Minds', a snippet of a leaked dialogue from Episode 4, "The Itch," reveals a preview of a possible new character.

The official Twitter account of 'Criminal Minds' posted the photo. The image shows a portion of the script, and with that, a conversation between Doug Adams and Derek Morgan. However, the highlight of the picture was the joke attached to Morgan's dialogue.

The script reads, "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]"

The picture, captioned "Page 9 from #CriminalMinda EP10x04 The Itch.: #tablereadfunnies #breenfrazier," has made fans think that the new character, Doug Adams, could be a regular on the show.

Beyond that, cast members have also been sharing photos of the set as well. Additionally, A.J. Cook, who portrays Jennifer Jareau, said that the ending of Season 9 will have a big influence on the continuation of the story.

"It's Season 10, its going to be a big season. I will say that the how Season 9 ends will directly impact Season 10," said Cook.

Joe Mantegna said that he will be directing Season 10 in the same way he directed the previous seasons. However, he mentioned that they are hoping for a bigger budget this time around

Also, while there is still no confirmation from production about this, Jane Lynch is rumored to be returning to the show for Season 10.

'Criminal Minds' is set to return on CBS this October 1.
