Kate's niece Meg and her BFF were grabbed and thrown into a van at the end of last week's Criminal Minds, but as we'll learn on Wednesday's season finale, this ain't no simple kidnapping.

Needless to say, it'll be all hands on deck for the BAU to find them, but pregnant Kate (Jennifer Love Hewitt) can only do so much: She's been put on bed rest, but, judging by the sneak peek below, nothing is gonna stop her from finding Meg.

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