The departure of one of 'Criminal Minds' main characters has been explained by the show's executive producer.
According to TV Guide, Simon Mirren explained that JJ, played by actress AJ Cook, will be returning to the show to tie up some loose ends this year.
He said: "We've always intimated that JJ's character has connections outside of our world - other more powerful elements in the government."
"Those powers that she's connected with come back into her life. So basically, what we're saying is, our loss is going to be somebody else's gain."
