CBS' hit police procedural drama TV series "NCIS: Los Angeles" season 7 is currently on a hiatus. When it comes back on air, fans should expect some interesting developments that will surely make them sit closer on the edge of their seats.

First up, the spoiler report from Entertainment Weekly teases on the return of a recurring character. The latter's resurfacing, however, won't be good news for the squad.

As further detailed by the media outlet, Peter Cambor, who plays the operational psychologist Nat Getz, will reappear in an upcoming episode that is slated to air this April.

For those who missed it, Dr. Getz has gone to the dark side for three months while on an undercover mission to topple down a Los Angeles-based terrorist organization. The character will be spotted on one of the security footages showing him stealing a "military transport of weapons."

The episode, which further details are yet to be revealed, will eventually see Callen (Chris O'Donnell) and Sam (LL Cool J) tracking down their mole. However, when things take turns for the worse, Getz will double-cross his colleagues. In fact, Entertainment Weekly shared a promo picture showing Callen being taken hostage. The site explained that Getz could be after for some information and it looks like he would be more than willing to hurt his fellow officers just to acquire them.

In the meantime, "NCIS: LA" will be back in the next couple of days with a brand-new episode.

The Futon Critic shared the synopsis for the 18^th segment titled "Exchange Rate." As stated, the whole squad will be shocked to find out that one of their own, Anna (Bar Paly), turns out to be the person behind the escape of a convicted Cuban spy who is expected to return to his country in a prisoner exchange. Meanwhile, Deeks (Eric Christian Olsen) begins to look down on himself to Kensi (Daniela Ruah).

Find out how these events unfold when "NCIS: LA" season 7 returns this Monday, Mar. 14 at 10 p.m. on CBS.
