CBS Quietly Confirms NCIS Doesn’t Need Gibbs at All

For nearly two decades, NCIS‘ Leroy Jethro Gibbs, played by Mark Harmon, was the heart of the crime drama. However, CBS has demonstrated that the long-running procedural can survive without its most recognizable character, even as the franchise just found a new reason to bring him back into the mix.

Harmon left the original series in 2021 after 18 seasons as Gibbs, who fiercely led the Major Case Response Team of NCIS. His character’s decision to remain in Alaska in Season 19 gave the veteran agent a fitting conclusion, allowing him to leave his demanding and long-winded career behind. Rather than immediately reversing their decision to axe his character, NCIS continued to develop its remaining characters and introduce new leadership.

Harmon’s replacement, Gary Cole, joined the series as Alden Parker, taking over as team leader after Gibbs’ departure. Although replacing a well-established character such as Gibbs presented an obvious challenge, Parker eventually found his place within the team. Meanwhile, NCIS operatives Timothy McGee, Nick Torres, and other agents continued solving cases, demonstrating that the show’s identity extended beyond Gibbs’ recognition.

Despite Gibbs’ exit from NCIS, CBS’ decision to bring him back to the franchise in NCIS: Origins Season 3 doesn’t necessarily undermine his original departure from NCIS during Season 19. Instead, it highlights how the character can remain important and versatile without dominating every storyline.

Harmon’s return to NCIS: Origins initially allowed the franchise to explore Gibbs’ history without requiring him to entirely reprise his leadership role. The prequel, in which Harmon returns, follows a younger Gibbs, played by actor Austin Stowell, while Harmon narrates his earlier experiences. Gibbs returned to the screen in the NCIS: Origins Season 3 premiere on Oct. 6, 2026, as a mystery connected to his past disrupts his peaceful retirement in Alaska.

CBS’s bringing Gibbs back into the NCIS fold also shows how the network preserved his role rather than erasing it entirely. While his original leadership role wasn’t at the forefront of his return to the franchise in NCIS: Origins, CBS still showed that by reintroducing him, they could selectively preserve his larger-than-life reputation while allowing other characters to carry the procedural forward.

Gibbs’ absence also gavean opportunity to establish a new and entertaining dynamic among other characters. Cole as Parker brought a different leadership style, while McGee’s experience positioned him as an increasingly important figure within the team.

That helped demonstrate that the series could evolve rather than depend indefinitely on one actor. The franchise’s continued investment in NCIS: Origins, which is currently in its third season, also paves the way to explore Gibbs as a versatile character without making his return a requirement for continued momentum in the original show.

Ultimately, CBS’ approach to bringing Gibbs back five years later suggests that the greatest value of his role may lie in his enduring legacy rather than in his constant presence. By no longer being a regular member of the original team’s lineup, his return and the expanded narrative of his overall character can generate anticipation for the audience.

As a new addition to NCIS: Origins, CBS continues to celebrate its most iconic character while keeping the door open for the next generation of agents to lead the way
