Look who's back!

JJ (A.J. Cook) returns from maternity leave on Wednesday's Criminal Minds and, naturally, the BAU is welcoming her back with opening arms.

Rossi (Joe Mantegna) and Reid (Matthew Gray Gubler) shower her with gifts, while Garcia (Kirsten Vangsness) has decorated JJ's desk with all-new photos of her boys Henry and Michael (Cook's real-life sons play her kids).

But where are Morgan (Shemar Moore) and Hotch (Thomas Gibson)? Find out in the exclusive first look above.

Criminal Minds airs Wednesdays at 9/8c on CBS.
