The landmark 500th episode of NCIS delivered one of the biggest shocks in the show’s history. Season 23, Episode 13, titled “All Good Things,” did not just celebrate a major milestone—it changed the future of the series forever. The episode featured the emotional and permanent exit of a long-time fan favorite, leaving the team and viewers reeling.
To understand the scale of this event, we have to look at the full picture of the cast and characters who brought this special hour to life. The milestone episode, which aired on CBS on Tuesday, March 24, 2026, brought together the current main cast and featured a surprising return to say goodbye to one of its most respected leaders.
The Main Cast of the 500th Episode
The 500th episode showcased the current NCIS team navigating a world where their agency had been dismantled. The core cast members each played a significant role as they dealt with the fallout of the shutdown and came together for one last case.
Rocky Carroll returned as Director Leon Vance, taking center stage in a story that would ultimately end his 18-season journey. Gary Cole played Alden Parker, who initially chose retirement rather than working for the agency absorbing NCIS. Sean Murray portrayed Timothy McGee, who tried to settle into a new position at the Army’s CID (Criminal Investigation Division) but was pulled back to help an old friend. Wilmer Valderrama played Nick Torres, who refused to work for the rival agency and instead joined the DEA to go undercover. Katrina Law appeared as Jessica Knight, who also took a role at CID. Brian Dietzen played Jimmy Palmer, the medical examiner who remained a steady presence, while Diona Reasonover appeared as Kasie Hines.
The episode’s emotional weight was carried by Carroll, whose character sacrificed everything to save the agency he had led for nearly two decades.
A Bittersweet Goodbye for Rocky Carroll
The central piece of news from the 500th episode is the departure of Rocky Carroll. After joining the series in Season 5, Carroll portrayed Director Leon Vance for 18 seasons. The actor confirmed that this exit was not his choice, but rather a creative decision by the writers to use the milestone for a massive story.
Carroll shared with TV Insider how executive producer Steven D. Binder approached him with the idea. The actor recounted Binder’s pitch: “We want to do something that really sends shockwaves through the TV community and the fan base, and your character is central to the storyline.” When Carroll heard the full arc—that Vance saves the agency but loses his life—he knew it was a powerful ending. He noted that he would have loved to stay until the series finale, but he recognized the quality of the story, saying, “After 18 seasons, I couldn’t have asked for more.”
The death scene was framed as a conversation between Vance and a younger version of Dr. Donald “Ducky” Mallard, played by Adam Campbell. This creative choice gave viewers a final, peaceful moment for Vance, allowing his character to walk into the light where he was greeted by the voice of his late wife, Jackie.
How the Team Came Together for the Final Case
With NCIS officially shut down at the beginning of the episode, the team was scattered. McGee and Knight accepted jobs at CID, while Torres went deep undercover with the DEA. Parker decided to retire, stepping away from law enforcement entirely.
The case that reunited them came from Billy Fuentes, a character familiar to long-time viewers. Billy was the young boy Gibbs helped build a treehouse for back in Season 1’s “Hung Out to Dry.” Now an adult, Billy came to McGee for help. His sister, a Navy petty officer, had been accused of murder, and he knew she was innocent. McGee, honoring the promise Gibbs had made years ago, reached out to the rest of the team. Torres left his undercover assignment, Parker came out of retirement, and Knight and McGee risked their new positions to work the case off the books.
The Shocking Ending Explained
As the team investigated, they uncovered a larger conspiracy involving a weapons smuggling ring connected to the Director of CID, Wayne Rogers, and his associate, Agent Thompson. The corruption ran deep, and when Vance discovered evidence that would expose them, Thompson planted a bomb in the NCIS evidence garage to destroy it.
Vance managed to stop the bomb, but Thompson shot him multiple times in the chest. Parker and Torres arrived in time to take Thompson down, but it was too late to save Vance. However, the episode revealed a twist: Vance was not wearing a protective vest. The final moments showed Vance speaking with a mysterious man who had been questioning him throughout the episode. The man, revealed to be the spirit of a young Ducky (Adam Campbell), was there to help Vance transition. Ducky assured Vance that his death was not in vain, telling him, “You saved your agency. Your legacy will live on.”

What Vance’s Death Means for the Agency
Because Vance stopped the cover-up, the crimes of CID Director Rogers were exposed. NCIS was reinstated, and the charges against Billy’s sister were dropped. Parker officially came out of retirement to lead the team again, returning to work as the agents began to rebuild.
Vance’s death marks a major shift for the series. As the Director for 18 years, he was the steady hand that guided NCIS through the transition after Gibbs left. His absence leaves a leadership vacuum that the show will need to address in the remaining episodes of Season 23 and moving into Season 24. While the team saved the agency, they now must learn to operate without the man who fought to keep it alive.
