Luke Alvez (Adam Rodriguez), an FBI Task Force agent, joins the BAU on Wednesday's Season 12 premiere of Criminal Minds to help catch those unsubs on the loose. Unsurprisingly, he and Garcia (Kirsten Vangsness), who still has a Morgan-sized hole in her heart, don't get off on the right foot.

As you can see in the exclusive sneak peek above, she's not exactly up for small talk, before going on a mini verbal diarrhea run laced with accidental sexual innuendo.

Baby girl, did you learn nothing from that sexual harassment seminar?
