Mark Harmon’s NCIS Return May Finally Confirm This Minblowing Gibbs Theory

by

Mark Harmon is coming back as Leroy Jethro Gibbs, and his appearance in a special two-part episode could prove a surprising theory about the former NCIS leader. Though Harmon was the central figure in NCIS for almost 20 years, his character retired from the main show in Season 19 and moved to Naktok Bay. He’s already made a brief appearance in a prequel series focused on Gibbs’s earlier Navy days, and will be back on NCIS very soon.

Though fans will always remember him and celebrate his impact, NCIS: Origins is exploring Gibbs’ early life, revealing more about his experiences in the 1990s. Mark Harmon returns to narrate as the older Gibbs, adding depth to Austin Stowell’s portrayal of the younger version. After making an appearance in the spinoff last year, a long-held secret is now bringing Harmon back to the NCIS universe.

Mark Harmon Is Returning To NCIS In November For The Franchise’s Crossover Event

Mark Harmon will reprise his role as Gibbs in a special event spanning both NCIS and NCIS: Origins on CBS. The episodes will air on Tuesdays, switching the usual timeslots to present the story in order. According to NCIS: Origins showrunners David J. North and Gina Lucita Monreal, the event will revisit Gibbs four years after he relocated to Alaska. While he’s been living a solitary life, the showrunners hint that Gibbs now has company.

According to the co-showrunners of Origins, David J. North and Gina Lucita Monreal, Mark Harmon will reprise his role as Leroy Jethro Gibbs for a special NCIS crossover event on November 11th. Four years after his character went into seclusion in Alaska, fans will finally learn what Gibbs has been up to, and discover he’s no longer living in solitude. The showrunners acknowledge how much viewers have missed Mark and are thrilled to bring him back.

Harmon shared that the storyline intrigued him and felt like a good moment to revisit Gibbs’s past. The upcoming ‘Origins’ crossover will explore a case from the 1990s – the death of a naval officer investigated by a young Gibbs (Austin Stowell) and his team – which is now being reopened. This suggests the current story is connecting with Gibbs because of his history with Mike Franks’ team and their original work on the case.

Gibbs’ NCIS: Origins Return Could Confirm A Mindbending Theory About Gibbs & Lala

Fans are buzzing about Gibbs no longer being alone in Alaska, especially considering a popular theory that’s been circulating. In the first season finale of NCIS: Origins, Lala was seriously injured in a car crash – she flipped her Jeep to avoid hitting a child. Though her character recovers and returns in Season 2, she’s surprised to find Gibbs in a relationship with Diane (Kathleen Kenny), sparking a wild theory among viewers.

Some viewers are hoping that Gibbs will end up with Lala Dominguez in Alaska on NCIS: Origins, especially since the show introduced his second wife and moved away from a potential romance between Gibbs and Lala. The upcoming crossover suggests Gibbs won’t be alone in Alaska, leading fans to believe Lala could be the one joining him. However, it might be too soon in the series to confirm this, so it’s also possible a former colleague will visit Gibbs instead.

It would be emotionally satisfying if, after being separated for years, Gibbs reunited with a former teammate. This would echo the idea of missed connections and timing, which has always been central to their relationship. Alternatively, the visitor could be Timothy McGee, who was spotted at Gibbs’ cabin in the recent season premiere of NCIS.

What Mark Harmon’s Return Means For The Future Of NCIS & NCIS: Origins

Mark Harmon seems open to returning to the NCIS universe as Gibbs, but only if the story is right. He’s already made a cameo appearance in the NCIS: Origins prequel series, first in the pilot episode and again in Season 2, showing he’s willing to reprise the role. While fans are happy to see glimpses of the older Gibbs, he hasn’t yet returned to the original NCIS series.

Although Mark Harmon’s return to the NCIS universe is thrilling, he won’t be in the original series. Because the new show involves teamwork, Gibbs might interact with some of his old colleagues. However, many NCIS viewers are still hoping Harmon will reprise his role at the Navy Yard, where Gibbs has a long history and close relationships with his team from the show’s beginning. Since Harmon is willing to return, his involvement with NCIS: Origins suggests a future appearance on NCIS is possible if the storyline is compelling enough.
