Mark Harmon, the beloved Leroy Jethro Gibbs of NCIS, has concluded his remarkable two-decade journey on the show. Gibbs’ departure was finalized in the 19th season when he made the decision to remain in Alaska. Although Harmon was initially credited in the final season, Season 20 has introduced Sean Murray as the new face, now portraying McGee.
The response from fans to this transition has been varied, with some embracing the change and others expressing a sense of loss with Gibbs’ departure. Harmon, in clarifying his decision, emphasized his dedication to keeping the character dynamic and facing new challenges.
Despite stepping away from the on-screen role, Harmon remains connected to the show behind the scenes, leaving the possibility slightly open for a potential guest appearance in the future. In the farewell episode titled “Great Wide Open,” Gibbs and McGee collaborate on a case in Alaska, concluding with Gibbs choosing to stay and part ways with NCIS.
Throughout the episode, subtle hints were dropped, creating a bittersweet farewell tour atmosphere. While the moment was poignant, many believe Gibbs has earned a well-deserved respite and an opportunity for solitude. The narrative intentionally leaves the door open for a potential return in future seasons, adding an element of anticipation for loyal fans.
