Paget Brewster's return to Criminal Minds has been confirmed.

How her character reemerges and how her fellow BAU members react remain unclear ... and complicated. Considering how she left, it will be tough to explain.

Much of the team does not handle finding out that Prentiss is still alive and well, according to TV Line's Michael Ausiello, "especially Dr. Reid, who feels betrayed."

With Brewster's contract status up in the air, her departure from the procedural in the March 16 episode titled "Hanley Waters" was left open-ended for a reason.

Learning that she faked her own death won't be easy to swallow for Reid, though, and it should be interesting to watch their relationship unfold in the fall.

As for A.J. Cook's J.J., not only is she back in DC, but she's getting a promotion!

Season Seven of Criminal Minds begins September 21. Sound off on it here!
