NCIS fans are feeling the weight of a major milestone — the departure of the final original cast member, Mark Harmon, who portrayed Special Agent Leroy Jethro Gibbs since the show’s debut in 2003. While Harmon officially stepped away from the series in Season 19, his absence is now being deeply felt as the show continues without any of its founding stars still active in the main cast.

Mark Harmon was the heart and soul of NCIS, leading the team with quiet strength, stern loyalty, and a mysterious backstory that kept fans hooked for over two decades. His character, Gibbs, became a symbol of integrity and resilience, making his exit feel like the end of a golden era for the series.

Although Harmon has remained involved behind the scenes as an executive producer, many fans still held hope for an eventual return, even if just for a special episode or finale. Now, with no original stars left on screen, viewers are left reminiscing about the early days and wondering what the future holds for the long-running drama.

The show continues to draw millions of viewers each week, but this latest goodbye marks a turning point. For many longtime fans, NCIS just won’t feel the same without Gibbs at the helm.
