NCIS fans are grappling with the emotional weight of a major turning pointโthe departure of Mark Harmon, the last remaining original cast member. As Special Agent Leroy Jethro Gibbs, Harmon anchored the series from its 2003 debut, officially stepping away in Season 19. Now, with no founding cast members left in the main ensemble, his absence is being felt more than ever.
For over two decades, Harmon was the backbone of NCIS, portraying Gibbs with quiet authority, unwavering loyalty, and a compelling air of mystery. His character came to embody the heart of the showโresilient, principled, and unforgettable. His departure marks the end of an era that many fans considered the golden age of the series.
While Harmon remains connected to the show behind the scenes as an executive producer, viewers had long hoped for a surprise returnโperhaps in a special episode or series finale. But as the show moves forward without any of its original stars, itโs become clear that a significant chapter has officially closed.
Despite these changes, NCIS continues to attract a loyal audience week after week. Still, for many longtime fans, the show just doesnโt feel the same without Gibbs leading the way.
