If you’ve been a loyal NCIS viewer, buckle up—because 2025 is shaping up to be one wild ride. From surprise comebacks to brand-new shows, the franchise isn’t slowing down anytime soon. And yes, Mark Harmon—the beloved face of Leroy Jethro Gibbs—is stirring up headlines again.

In this deep-dive, we’ll unpack every major NCIS update you need to know, including Harmon’s rumored return, the latest spinoffs in development, and all the unexpected plot twists that have longtime fans buzzing. Whether you’re a die-hard fan or just hopping back in, there’s a lot to catch up on.

Is Gibbs Really Coming Back?

Let’s cut to the chase: the rumors are true—Mark Harmon is set to return to the NCIS universe. While he stepped away in Season 19, new developments suggest he’s not finished with Gibbs just yet. Sources confirm Harmon will appear in NCIS: Origins, and a potential guest role in NCIS Season 22 isn’t off the table.

How Harmon Will Re-Enter the Storyline

Harmon’s role may take the form of flashbacks or narration, but executive producers hint that his presence will have real-time consequences. Expect big emotional stakes and high-tension callbacks to Gibbs’ moral code and mysterious past.

What Is NCIS: Origins?

Think of it as the prequel you never knew you needed. NCIS: Origins is diving deep into the formative years of a young Leroy Jethro Gibbs, set in the 1990s. Actor Austin Stowell will portray the younger version of the iconic agent, while Harmon will reportedly narrate and executive produce.

Exploring Gibbs’ Backstory

This series isn’t just fan service—it promises to reveal how Gibbs’ legendary rulebook and gruff exterior were shaped. Expect new characters, never-before-seen mentors like Mike Franks, and gritty cases that set the tone for Gibbs’ future career.

New NCIS Spinoffs: Global Expansion Ahead

NCIS: Tony & Ziva Spinoff Series

That’s right—Tiva is officially back! A European-set spinoff starring Michael Weatherly and Cote de Pablo will follow their lives post-NCIS as they try to balance espionage and parenting. This one’s going to blend action, romance, and international stakes.

NCIS: Sydney Success Sparks More Global Ideas

After NCIS: Sydney’s surprising breakout, producers are now eyeing other international locations. Think NCIS: Tokyo, NCIS: Berlin, or even NCIS: Cape Town. CBS has made it clear: the brand is global now.

NCIS Season 22: What To Expect

The Legacy Continues Without Gibbs?

Not quite. While Gibbs isn’t expected to return as a regular, his legacy still casts a long shadow. Season 22 picks up the pace with new agents, fresh threats, and possibly even a crossover with the Origins storyline.

Tributes and Easter Eggs

Expect touching tributes to David McCallum (Ducky), who passed away in 2023. Longtime viewers will catch subtle nods and emotional callbacks sprinkled throughout the season.

Plot Twists That Will Shake Up The Franchise

Shifting Alliances and Betrayals

Producers have teased that trusted agents may flip, alliances may fracture, and not everyone will make it out unscathed. One key character may even be revealed as a double agent.

Gibbs’ Secret Missions Revealed?

Rumors swirl that the new series will reveal covert missions Gibbs completed before joining NCIS—the kind of operations that were too dark to mention… until now.

Cast Changes and Guest Appearances

Who’s Joining the Team?

A few fresh faces are shaking up the cast in Season 22. While names are under wraps, insiders say we can expect a former CIA analyst, a cyber-specialist with a murky past, and a surprising legacy hire—possibly the child of a past agent.

Fan-Favorite Returns

Aside from Harmon, expect short arcs or cameos from Tony DiNozzo, Ziva David, Abby Sciuto (yes, maybe!), and even Bishop. NCIS is going all in on nostalgia—smart move.

Behind the Scenes: Creative Shifts

New Showrunners, New Vision

NCIS has brought in a new showrunning duo to breathe life into both the main series and Origins. Their goal? Tighter storytelling, emotional arcs, and season-long mysteries instead of case-of-the-week formulas.

More Cinematic Direction

Expect slicker production, more serialized storytelling, and a darker, more grounded tone—especially in Origins.

Why Now? The Strategic Timing Behind the Expansion

The NCIS franchise has always ebbed and flowed, but 2025 marks a resurgence. With streaming audiences booming and long-time fans craving character-driven drama, this is prime time for an overhaul.

Filling the Void Left by Other Crime Dramas

As other procedural powerhouses fade out, NCIS is positioning itself to reclaim dominance—and Harmon’s return is just the spark it needed.

Fan Reactions: Hope, Nostalgia, and Skepticism

Why Fans Are All In

The Gibbs nostalgia is real. Fans are eager for emotional closure, untold stories, and a return to character-first storytelling. The buzz on social media? Massive.

Concerns About Overextension

Still, some worry that too many spinoffs could dilute the NCIS brand. Will all these storylines stay cohesive? Or is CBS biting off more than it can chew?

What This Means for the NCIS Franchise’s Future

The writing is on the wall: NCIS is evolving, and Harmon’s reappearance is the glue holding it all together. With a mix of old-school fan service, modern twists, and international intrigue, the franchise is betting big—and it just might pay off.

Conclusion: A Bold New Era for NCIS Begins
