The NCIS team investigated a fishy situation on the latest episode of "NCIS: Los Angeles."

In "Fish Out of Water," the NCIS team investigates an explosion at a fish market. They do a joint investigation with the DEA, and one of their agents goes undercover. The undercover cop, Talia, teams up with Deeks (Eric Christian Olsen) and represents the one path that Deeks and Kensi (Daniela Ruah) can take once Kensi returns home from Afghanistan.

They manage to stop the terrorists before they blow up an event and 5,000 people.

The team takes charge of the situation so when the bomb goes off, it detonates in an empty parking lot on the beach.

On the romantic side of things, Sam (LL Cool J) invites Callen (Chris O'Donnell) to come over for dinner with Joelle, but Callen says he wants some things to remain private.

Meanwhile, in Afghanistan, Kensi awakes to the sound of Granger (Miguel Ferrer) talking, and finds out that they lost a helicopter in the same place where Sabatino left her.

It's reported that the White Ghost is nearby, so Kensi gets on her bike to go after him. But when she finally sees White Ghost's face, she reacts by shooting him in the arm before she has to retreat.

When she returns to the base, she tells Granger that she barely saw his face, and could not get a good shot. It's not Sabatino, but her shocked reaction could indicate that it's Jack.

On the next episode, "Between the Lines," "When a local gang records the execution of an ATF agent, the team is tasked with determining how his cover was blown. Kensi goes missing in Afghanistan which makes Granger worry about her safety."

"Between the Lines" airs Tuesday, March 18 at 9 p.m. EST on CBS.
