why is vance leaving ncis

Leon Vance is leaving NCIS because the writers chose to kill off the character in the show’s 500th episode, not because Rocky Carroll wanted to leave.

Quick Scoop: Why is Vance leaving NCIS?

In the milestone 500th episode, Director Leon Vance dies after being shot multiple times while stopping a smuggling syndicate and protecting crucial evidence tied to NCIS’ future. His sacrifice clears a petty officer’s name, exposes the corrupt CID Director Wayne Rogers, and ultimately gets NCIS reinstated after it had been shut down due to falsified budget numbers.

Behind the scenes, this exit was a creative decision from the writers, who approached Rocky Carroll in late 2025 to use the 500th episode as the endpoint of Vance’s story. Carroll has confirmed that it was not his choice to leave; the showrunners decided to close the chapter on one of the series’ longest- serving leaders in a dramatic, heroic way.

In-story, Vance gives his life to save the agency. Out-of-story, the writers wanted a big, emotional turning point for NCIS’ 500th episode and chose Vance’s death as that moment.
