The Iconic Leroy Jethro Gibbs is No Longer Alone in the Alaskan Wilderness
Imagine this: the vast, silent expanse of Alaska, a rustic cabin, and Gibbs, tinkering with an old radio, a journal in hand. That’s precisely where we find Mark Harmon’s beloved character, Leroy Jethro Gibbs, in the exclusive first look at the upcoming NCIS and NCIS: Origins crossover. After departing the flagship series as a regular in Season 19, Gibbs chose a life of solitude in the wilderness. However, this special event promises to pull him back into the narrative, confirming he's "no longer alone," as teased by co-showrunners David J. North and Gina Lucita Monreal.

This return isn't just a brief voiceover—Harmon is back on screen. Fans have eagerly awaited a substantial return since his last regular appearance. His continued involvement as an executive producer and narrator for the prequel series, NCIS: Origins, has kept him connected to the franchise. Still, nothing beats seeing the man himself. This guest appearance in the Origins half of the crossover marks a significant moment, promising to delve deeper into Gibbs's past while bridging it with the present.

Unraveling a Decades-Spanning Mystery: What to Expect from the Crossover Event
Get ready for a "Super Tuesday" on November 11, 2025, as CBS dedicates a full two hours to the NCIS universe, commemorating Veteran's Day. The crossover kicks off with NCIS: Origins at 8/7c, which, for one night, takes over the usual NCIS time slot. This is a strategic move to ensure narrative flow, as the younger Gibbs (played by Austin Stowell) and his 1990s NIS team investigate the small-town death of a naval officer in Serenity, California.

The baton then passes to the flagship NCIS at 9/8c. Here, the present-day team, led by Alden Parker, unexpectedly reopens the very same cold case after an inmate breaks free from prison just weeks before his release. The narrative elegantly bridges the timeline gap, connecting Gibbs's earliest days as a Special Agent with the modern MCRT (Major Case Response Team). It’s a clever way to show the enduring impact of cases and how past events echo into the future.
"Over the years, the outside changes, but inside, you still feel all the same things. You'll see."

The statement from co-showrunners David J. North and Gina Lucita Monreal—"We don't want to give too much away, but let's just say Gibbs is no longer alone"—has sent ripples of speculation through the fan community. This simple phrase suggests a significant development for Gibbs, who purposefully sought solitude in Alaska. Who could be with him?
Fan theories abound on Reddit. Some wonder if it's a new companion, perhaps an old flame like Lala, whose past relationship with Gibbs is yet to be fully explored in Origins. Others optimistically hope for a visit from beloved characters like Tony DiNozzo and Ziva David, perhaps with their daughter Tali, creating a multi-generational reunion. Even a loyal canine companion has been suggested. The mystery surrounding Gibbs's company adds a layer of anticipation to an already exciting event, hinting at a new chapter for the character.

Mark Harmon's On-Screen Presence Elevates the NCIS Universe for Fans and Cast Alike
Mark Harmon’s return is more than just a fan-service cameo; it's a narrative decision that significantly impacts the show's quality. Kyle Schmid, who portrays Mike Franks on NCIS: Origins, articulated this perfectly, stating, “His presence does something to the show that just, I think elevates it.” Schmid expresses immense gratitude for Harmon's belief in Origins, acknowledging the risk involved in investing in a prequel. Source: [TV Insider, "Kyle Schmid Says Mark Harmon’s ‘NCIS: Origins’ Return for Crossover ‘Elevates’ the Show," Nov. 4, 2025]
Harmon himself has voiced his approval for the direction of Origins, emphasizing his pride in the storytelling and how it pushes boundaries by diving deeper into characters' backstories. He found an idea for Gibbs that resonated with him, making it "a good time to check in with him." This mutual respect between the original star and the new creative team underscores a commitment to character authenticity and a rich, evolving narrative that respects the franchise's legacy.
A Glimpse into the Past: Austin Stowell's Young Gibbs
While Harmon embodies the seasoned, world-weary Gibbs, Austin Stowell carries the torch for his younger iteration in NCIS: Origins. Stowell openly admits to the "nerve-wracking" experience of portraying a character so deeply ingrained in television history. He described it as a series of "first times," from leading a network TV show to taking on an already established role. This challenge is precisely what makes the crossover so compelling: witnessing the genesis of the iconic agent we've known for decades, and how his early experiences shape the man he becomes.
The juxtaposition of Stowell's young, developing Gibbs with Harmon's older, reflective version offers viewers a unique perspective on character development. It allows for a deeper understanding of Gibbs's rules, his quirks, and the origins of his resolute nature. This kind of storytelling provides a satisfying arc for long-time fans and an engaging entry point for new viewers, illustrating the cause-and-effect of his early career on his later character.
"I’m very proud of the storytelling that David and Gina are doing on Origins. They continue to push boundaries and dive deeper into the characters’ backstories. They came to me with an idea for Gibbs that I liked, and it seemed like a good time to check in with him. I hope fans enjoy it."

More Familiar Faces: The Return of Agent Vera Strickland and Unexpected Twists
Mark Harmon isn’t the only familiar face making a comeback. Roma Maffia is also reprising her role as Agent Vera Strickland, a character last seen in NCIS way back in 2013 during Season 11. Her return as a retired NCIS agent in the present day adds another layer of nostalgic depth to the crossover, as her younger counterpart is already a part of the NCIS: Origins cast. This dual appearance suggests a strong connection to the central case spanning the decades.
Unlike Harmon, who is confirmed to appear only in the Origins hour of the crossover, Maffia's character will bridge both the 1992 and present-day timelines. This distinction highlights a careful narrative choice: Gibbs's current story unfolds in a particular context, while other characters serve as more direct links between past and present. The re-opened case involving the '90s NIS team, including Gibbs and Franks, will see the present-day MCRT seeking Strickland's help, weaving her history directly into the current investigation.
A Mini-Story of Fan Anticipation: The Case of "Sarah's Return"
For many, this event is monumental. Imagine Sarah, a dedicated NCIS fan who, like many, drifted away after Gibbs's initial departure from the main series. She'd occasionally catch an Origins episode, enjoying Harmon's narration, but felt a piece of the original magic was missing. When the news broke of his on-screen return, not just for a fleeting moment, but as a central part of a major crossover, it was the push she needed. She immediately marked November 11th in her calendar, texted her fellow fan friends, and even considered rewatching some classic Gibbs episodes to prepare. It's more than just a show for Sarah; it's a reunion with a character who felt like family for nearly two decades. This kind of personal connection is what makes Harmon's return so impactful.

Addressing Expectations: Limitations and Other Perspectives on Harmon's Comeback
While the excitement for Mark Harmon’s return is palpable, it's important to manage expectations. One clear limitation is that his on-screen appearance as older Gibbs is confirmed only for the NCIS: Origins episode, not the main NCIS hour. Source: [CBS, "Another NCIS character makes a return after over a decade," published alongside images, unknown date/author, but published with Nov 2025 articles]. This means that a full reunion with the current NCIS cast, which many fans might be hoping for, won't happen during this crossover event. It’s a bittersweet detail, offering a glimpse of Gibbs without fully reintegrating him into the current team’s dynamics. The decision likely stems from maintaining the narrative integrity of Gibbs's Alaskan solitude while still giving fans the chance to check in on him.
Another point to consider comes from a less official source. The National Examiner recently reported that a source close to Harmon claimed he was "bored" with semi-retirement and missed the "routine, the crew, the fans, the whole buzz of being on set." While this paints a picture of Harmon yearning for the spotlight, it contrasts with Harmon's own official statement, where he expressed pride in Origins' storytelling and liking the specific idea presented for Gibbs's return. It's a plausible human element—missing one's work—but it’s important to treat such uncredited claims as speculative rather than definitive reasons for his decision, especially when Harmon's own words emphasize the quality of the narrative.
