March 21, 2014 Updated: July 18, 2015

NCIS Los Angeles Season 5 Episode 18 is set for Tuesday, March 25, 9:00 p.m. ET on CBS.

In Episode 18, “Zero Days” the NCIS: LA team is called in to determine if the computer system that controls Russian missiles is at risk after Eric overhears his friend, a computer systems expert, being attacked during online game play.

Meanwhile, Kensi is shocked when a familiar face from her past shows up in Afghanistan.

Given that Kensi was once engaged to a Marine by the name of Jack, and Matthew Del Negro guest stars as a “Jack Simon,” there’s a possibility that the “familiar face” Kensi meets is her ex-fiancee.

Jack, who served in Fallujah, suffered from PTSD, and broke up with Kensi on a Christmas morning, could also be the infamous White Ghost. If that is so, Kensi could be headed for trouble in Episode 18.

Other guest stars in “Zero Days” include Tate Ellington (Ira Wells), Jim Holmes (Lance Witten), Jack Topalian (Boris), Ali Olomi (Insurgent), Jeronimo Spinx (NCIS Agent Thompson), and Natalie Britton (Receptionist).
