Which of the NATS will spark this ominous inquiry? Any of the wannabe agents could easily be investigated for breaking the no sex rule, but something tells us this is a tad more serious than whose boffing who.

Along with the major players, Elias Harper (Rick Cosnett), Brandon Fletcher (Jacob Artist), and Samar (Marjan Narshat) will also appear. Deputy Director Clayton (Mark Pellegrino), however, will not appear.

"Quantico" will air on Dec. 6, just a week before the drama takes on its midseason finale. In the meantime, viewers can watch Simon dig himself into a whole during Nov. 29's "Guilty."

Quantico airs Sundays at 10 p.m. ET on ABC.
