Mark Harmon Spotted Back on Set — Is Gibbs Finally Returning to NCIS? The sight of Mark Harmon near the NCIS set has fans buzzing louder than ever, reigniting speculation about a long-awaited Gibbs comeback. After leaving the show in Season 19, Harmon’s absence created a void that even the most dedicated cast members have struggled to fill. Now, with reports of him being seen near the production lot and rumors of scenes being filmed under tight secrecy, the question on everyone’s mind is whether Leroy Jethro Gibbs is truly coming home.

Insiders suggest Harmon’s visit wasn’t casual. Crew members have reportedly been instructed to maintain strict confidentiality, and the episode schedule for upcoming weeks has been locked down to avoid leaks. It’s the kind of behind-the-scenes activity that usually signals a major reveal, and fans know NCIS rarely stirs up this kind of mystery without reason.

For longtime viewers, Gibbs’ potential return carries more emotional weight than any new storyline could. His leadership, moral compass, and stoic wisdom defined the show’s golden era, and seeing him step back into frame—even for a brief appearance—would be a moment of television history.

Whether it’s for a flashback, a one-episode cameo, or something bigger, Mark Harmon’s presence near the set has reignited a fire in the NCIS fandom. After years of uncertainty, one thing is clear: Gibbs’ shadow still looms large over the team, and the world isn’t done with him yet.
