NCIS: Los Angeles' Densi may hit a little turbulence in the season 6 premiere.

'NCIS: LA' To Reach 'Zenith' At New Night & Time, What To Expect From Premiere

Detective Marty Deeks and Agent Kensi Blye will spend part of "Deep Trouble: Part 2" looking for Sam and Callen via helicopter, but the pair will also have to deal with DEA Agent Talia's unstoppable urge to best Kensi and land herself a Deeks.

If the ladies' competition felt a little fierce during the season 5 finale, TV Line promises that the battle will get much worse when the premiere opens.

However, there may be a ray of hope on the horizon for Talia and Kensi. Dennis Smith directed the premiere, which was filmed directly following the season 5 finale, and the NCIS veteran dropped a few hints about the future of the series' latest love triangle.

"Big #NCISLA 'Kensi and Deek's' shoot today. Kensi's bonding, but with who?" Smith teased during filming.

While the little love drama plays out back at the Office of Special Ops headquarters, Sam and CAllen will be trapped on a bomb-laden submarine. To make matters worse, it looks like their little vessel will soon spring a leak (see photos here).
