Mark Harmon has been the face of NCIS for nearly two decades, but even the legendary actor has some regrets about his time on the show. While he played Special Agent Leroy Jethro Gibbs with dedication and intensity, there’s one decision he reportedly wishes had gone differently—and fans had no idea until now.

Sources close to the production have revealed that Harmon regrets how his departure was handled. While he officially stepped away from the series in Season 19, insiders say he wished for a more dramatic and emotional send-off. Instead, Gibbs quietly left after deciding to stay in Alaska, leaving many fans feeling like his exit lacked the impact it deserved.

Another regret involves his long-rumored feud with Pauley Perrette, who played Abby Sciuto. Their behind-the-scenes conflict reportedly led to Perrette’s unexpected departure, and while Harmon has never spoken publicly about it, some believe he wishes things had ended differently between them.

Despite these regrets, Harmon remains a beloved figure in NCIS history. With the door always open for a possible return, fans are hopeful that Gibbs might one day get the farewell moment he truly deserves.
