NCIS: Los Angeles' Deeks and Kensi aren't as sneaky as they think.

Three-Episode Story Coming On 'NCIS: LA', When Will The Interconnected Plot Begin?

The truth about the Densi relationship will come tumbling out during "Fighting Shadows," and the LAPD detective and NCIS agent will quickly find out that their little tryst isn't as inconspicuous as they may have liked.

Callen (Chris O'Donnell) will confront Deeks (Eric Christian Olsen) about his choice of girlfriend during episode 18, and the intrepid investigator will rattle off a list of agents who have already figured out Densi's blatantly obvious relationship.

"Sam, Nell, Hetty, of course. Eric took a while but he finally got there. They guys in the motorpool. Pretty much everyone at this point," Callen explains in a new sneak peek (see video below). "Granger I'm not so sure about."

When Granger (Miguel Ferrer) does find out, however, Callen is quite confident he will crush both members of the illicit romance.

All in all, it looks like next Monday will be a dark day for workplace liaisons. "Fighting Shadows" will be even harder for Deeks as the shaggy-haired detective will find himself in hot water courtesy of a dangerous secret.
