Kasie Hines has always been the team’s technical genius—but Season 23 is putting her at the center of one of NCIS’ most personal cases in years.
Episode 17 ended with a chilling twist after a late-night system upgrade turned into a murder investigation and cyberattack inside headquarters. The biggest shock came when Kasie revealed the stolen file labeled “Edna” wasn’t a person—it was a program she created herself.
Now, Episode 18’s promo confirms just how serious the situation really is.
The mysterious software appears valuable enough to trigger blackmail and violence, and Kasie believes her work may have played a role in the tragedy that unfolded. As Parker, Jimmy, and Sam help unravel the conspiracy behind the theft, the case is becoming more than just another mission—it’s a deeply personal crisis for Kasie that could reshape her role within the agency moving forward.
