Garcia doesn't know when to hold 'em or fold 'em.

On Wednesday's Criminal Minds (9/8c, CBS), Rossi (Joe Mantegna) plays poker with Garcia (Kirsten Vangsness) to take her mind off being in Witness Protection at the BAU. Unsurprisingly, she's not that great at it and she can't stop thinking about the Dirty Dozen.

"This will not go on forever, Penelope," Rossi says in the exclusive sneak peek above.

"It feels like it will," she says. "I'm scared."

How does Rossi reassure her? Watch the clip to find out.

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