The NCIS season 23 finale is coming, and if Brian Dietzen is to be believed, it is going to leave a mark. According to TV Insider, the long running CBS drama has been searching for solid ground ever since the NCIS Director Vance death storyline gutted one of its most beloved characters. Rocky Carroll spent nearly twenty years on this show. Watching Director Leon Vance die in the line of duty hit the team hard, and they are still carrying that weight. CBS has yet to name a permanent replacement, and that open wound has been a quiet undercurrent all season long.

Brian Dietzen Is Telling Fans to Pay Attention

At CBS Fest, Dietzen sat down to share his thoughts on the ‘NCIS’ Season 23 Finale, and what he had to say is going to have fans setting their DVRs. He stopped well short of giving anything away, but his comments carried the unmistakable weight of someone who knows the ending lands hard. He drew a comparison to the 500th episode, not in terms of spectacle, but in terms of consequence. The NCIS finale twist he teased is not a throwaway moment. According to Dietzen, the final minutes of Sons and Daughters have real staying power and could send the show in a new direction entirely.

Everything We Know About the ‘NCIS’ Season 23 Finale

The NCIS season ending arrives on May 12 with an episode built around a case that refuses to stay buried. One year after a fatal coffee shop bombing, a new explosion raises fresh doubts about whether the original suspect really acted alone. The team is pulled back into something that cuts close to home, with themes of loyalty and legacy running through the hour. It is the kind of story that tends to double as a mirror for where the characters stand, which makes the final moments feel even more loaded.

The Show Has Earned Its Reputation for Big Swings

Longtime viewers know better than to assume they have seen everything NCIS has to offer. The NCIS shocking ending tradition stretches back years. Kate, played by Sasha Alexander, was killed in a moment that nobody saw coming. Mark Harmon‘s Gibbs stepped away from the team in a goodbye that felt both earned and heartbreaking. The Season 9 finale left the cast in chaos while Ducky, played by David McCallum, fought for his life. Ziva, portrayed by Cote de Pablo, staging her own death ranks among the most stunning reveals the show has ever pulled off. With all of that history behind it, the NCIS finale 2026 has every reason to aim just as high.

NCIS airs Tuesday nights at 8/7c, and the season finale airs May 12 on CBS and streams the next day on Paramount+.
