For almost two decades, Leroy Jethro Gibbs, portrayed by the incomparable Mark Harmon, was the stoic, rule-following, boat-building core of the Naval Criminal Investigative Service (NCIS). When Harmon departed the flagship series in 2021, Gibbs settled into a quiet life of solitude in Alaska, finally finding peace after a lifetime of service and loss.
The NCIS universe, however, is never truly complete without its patriarch. While Harmon has remained intimately involved as the executive producer and narrator of the prequel series NCIS: Origins, fans have long awaited an on-screen update. Their patience will be rewarded on Veterans Day, Tuesday, November 11, as the franchise unveils its first major two-hour crossover event.
🌉 The Decades-Spanning Crossover Event
The upcoming crossover is ingeniously designed to link Gibbs’ past, as explored in the ’90s-set NCIS: Origins (starring Austin Stowell as the younger Gibbs), directly to the present-day investigations of the NCIS team.
Part One: The Origins Connection (8:00 PM ET/PT)
The event will begin with a one-time timeslot switch, placing NCIS: Origins in the 8 p.m. slot. This hour will focus on a small-town death of a naval officer that the young NIS (Naval Investigative Service, NCIS’ predecessor) agent Gibbs and the Camp Pendleton team, led by Mike Franks (Kyle Schmid), investigated in the early 1990s.
Crucially, Mark Harmon will appear in the Origins portion of the night. This special guest spot will provide the long-awaited update on modern-day Gibbs in Alaska. The mystery of the ’90s cold case will serve as the narrative connective tissue, suggesting that the original investigation may contain clues or unfinished business that requires the legendary agent’s insight, even in retirement.
Part Two: The Present-Day Fallout (9:00 PM ET/PT)
The storyline then continues in the flagship series, NCIS, where Agent Alden Parker (Gary Cole) and the current MCRT team unexpectedly reopen the decades-old cold case. The current investigation will directly intersect with or be informed by the events of Gibbs’ past, showcasing how the foundational work of the NIS agents still impacts justice decades later.
This format provides a satisfying temporal loop, allowing the audience to see a case unfold in the past, get an update on the retired agent who worked it, and then watch the modern team bring the cold case to a final resolution.

🤫 Gibbs’ Secret: He’s No Longer Alone
Perhaps the most tantalizing detail revealed by showrunners and executive producers David J. North and Gina Lucita Monreal is a short, cryptic sentence about Gibbs’ current life: “We don’t want to give too much away, but let’s just say Gibbs is no longer alone.”
This revelation is a massive plot point for a character who departed seeking “solitude” in the remote Alaskan wilderness. Speculation has already run wild across the NCIS fandom. The most popular theories include:
- A new romantic partner: Given Gibbs’ storied history of marriage, a new, late-in-life connection would be a significant development and a source of emotional warmth for the former agent.
- The return of an old flame: Could it be a reconciliation with an existing character from his past, perhaps one tied to the new Origins timeline?
- An unexpected family member: While less likely, the new companion could be a distant relative or someone connected to his immediate family’s legacy.
- A trusted former colleague: The mystery companion might be someone from the NCIS team who decided to join Gibbs for a shared, quiet retirement.
Mark Harmon expressed his enthusiasm for the story idea that convinced him to step back in front of the camera: “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.” This statement reinforces that the return is driven by a genuine, compelling story beat that honors the character’s post-retirement journey.

🎖️ A Veterans Day Tribute
The decision to air this historic crossover event on Veterans Day, November 11, is highly symbolic. The NCIS franchise is rooted in the military, with nearly every major character having a background in service or investigating crimes related to the Navy and Marine Corps.
Veterans Day is an ideal backdrop for the return of Leroy Jethro Gibbs, a decorated former Marine Scout Sniper whose entire career was defined by his commitment to service and justice for his fellow servicemen and women. The two-part mystery, stretching from Gibbs’ early days with NIS to the modern NCIS team, serves as a decades-spanning tribute to the enduring nature of their work.
The emotional resonance of Harmon’s return on this specific date will undoubtedly amplify the already high viewership, turning the television event into a true franchise milestone.
🎬 The Legacy of Harmon’s Involvement
Even in his diminished on-screen role, Mark Harmon remains the bedrock of the entire NCIS universe. His continuous work as an Executive Producer on both the flagship show and NCIS: Origins (where his son, Sean Harmon, previously served as a consultant and appeared in flashback sequences) ensures that Gibbs’ legacy and core principles remain intact.
Harmon’s presence, even as a narrator in Origins, provides continuity and a sense of gravity, validating Austin Stowell’s portrayal of the younger Gibbs. The Veterans Day crossover will now provide the rare experience of watching the two generations of Gibbs—Austin Stowell in the ’90s and Mark Harmon in the present—converge on the same case, a true narrative gift to the fans who have followed Gibbs’ Rule 1: “Never screw over your partner.”
The November 11 crossover is poised to be more than just a ratings hit; it’s a necessary, emotional check-in that validates the character’s legacy and sets the stage for the next era of the sprawling NCIS franchise.
