Eric Beale will be the star witness of an upcoming episode of "NCIS: Los Angeles" due to his gaming addiction.

In Episode 18, "Zero Days," the technical operator will be a major witness in an investigation when he overhears another gamer's real-life fight with an assailant. 

It turns out that the assaulted gamer is a computers systems expert and friend of Eric's (Barrett Foa). Eric then goes out into the field as Callen's (Chris O'Donnell) team investigates. 

"Will Hetty send Nell and Eric into the field to help solve a case? #keepwatching #staytuned #NCISLA," teased executive producer John Peter Kousakis on Twitter. 

Meanwhile, in Afghanistan, Kensi's (Daniela Ruah) ex-fiancee will make an appearance again in the March 25 episode. 

On the latest episode of "NCIS: LA," "Fish Out of Water," the NCIS team investigated an explosion at a fish market.

In the episode, the team does 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 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 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.
