For longtime NCIS viewers, Michael Weatherly walking back into the Washington, D.C. headquarters as Tony DiNozzo is more than a familiar face returning to a familiar workplace. It is a reminder of an earlier era of the CBS franchise, when Tony, Gibbs, McGee, Ziva, Abby, Ducky and the rest of the team helped turn NCIS into one of television’s defining procedural dramas.
Now, as Season 24 prepares to begin, Weatherly is officially returning as Tony for a season-long arc, beginning with the premiere on October 6, 2026. CBS confirmed the comeback in July, noting that Weatherly previously starred on the series for 13 seasons and appeared in more than 300 episodes.
And while nostalgia is obviously part of the equation, Weatherly himself has pointed to two much bigger reasons for why the timing of Tony’s return makes sense. One of them is directly connected to CBS bringing another NCIS legend back into the spotlight: Mark Harmon.
The result is a Season 24 that appears to be deliberately connecting the franchise’s past with its present rather than simply bringing back an old character for a quick cameo.
Tony DiNozzo Is Really Coming Home
Tony DiNozzo has always occupied a unique place in NCIS history. He was funny, impulsive, occasionally immature and constantly capable of turning a serious investigation into an opportunity for a movie reference or an ill-timed joke. But beneath that personality was an agent who gradually grew into one of the team’s most dependable members.
Weatherly left the main series in 2016 after 13 seasons, and Tony’s departure was closely tied to his relationship with Ziva David and the discovery that they had a daughter, Tali. Since then, the character’s life has continued away from the Washington office.
That distance is important because the Tony coming back in Season 24 is not necessarily the exact same Tony viewers remember from the early seasons.
Weatherly has already returned to the character through NCIS: Tony & Ziva, the Paramount+ expansion that reunited Tony with Cote de Pablo’s Ziva. That experience allowed the actor to explore a different stage of Tony’s life, one shaped by family, responsibility and the consequences of everything that happened before.
Weatherly has described the Tony & Ziva experience as part of the reason Tony can now return to the mothership as a “new and improved” version of the character.
That distinction could become one of the most interesting parts of Season 24.
Tony is no longer simply the charismatic agent who left the NCIS bullpen years ago. He has spent years building a life outside the agency, and CBS has given him a very specific reason to return to Washington.
According to the Season 24 premiere synopsis, Tony arrives in D.C. to establish a satellite office for his private security company, Salus Mondiale. At the same time, the NCIS team is dealing with the aftermath of a shooting involving McGee’s son and investigating a new threat involving the Secretary of the Navy. Tony ends up helping the team when they need an unexpected source of expertise.
That setup makes his return feel organic rather than forced.
He is not suddenly being pulled back into NCIS simply because the writers want a nostalgic reunion. Tony has his own professional reason for being in Washington, while circumstances bring him back into contact with the people and organization he left behind.
And that brings us to the first major reason for the timing of his comeback.
Reason No. 1: CBS Is Leaning Into the Power of the NCIS Legacy
Weatherly’s return is happening during a particularly nostalgia-heavy period for the NCIS universe.
The franchise is no longer just one television series. It has expanded into multiple shows, different generations of characters and stories that allow CBS to revisit recognizable figures while continuing to build new ones.
But the most striking part of the current strategy is Mark Harmon’s return as Gibbs in NCIS: Origins.
Harmon spent 18 seasons playing Leroy Jethro Gibbs on the original NCIS, and CBS has confirmed that he will appear throughout Season 3 of NCIS: Origins as part of a season-long mystery connected to Gibbs’ past. Harmon also continues to narrate the series.
For fans who associate NCIS with the Gibbs era, that is a significant development.
And Weatherly has explicitly connected the timing of his own return with what CBS is doing around Harmon.
In an interview with TV Insider, Weatherly explained that one practical reason for his comeback is the way CBS is building its Tuesday-night NCIS programming. He pointed to the broader franchise lineup, including NCIS: New York, and specifically highlighted Harmon’s return to an on-camera role in NCIS: Origins.
That is an important clue about how CBS appears to be thinking about the franchise.
Tony DiNozzo and Gibbs represent different pieces of the original NCIS identity. Gibbs was the central leader, while Tony was one of the show’s most recognizable personalities. Bringing these characters back in the same broader television era creates a connection between the original generation of NCIS and the current franchise.
It does not mean Tony and Gibbs are necessarily going to share scenes in Season 24. They belong to different parts of the NCIS universe at the moment.
But their simultaneous presence matters symbolically.
CBS is reminding viewers that the franchise has a history.
And that history is still useful.
Mark Harmon Makes Tony’s Return Feel Even Bigger
There is something interesting about the way CBS has positioned Mark Harmon and Michael Weatherly.
Neither return requires the original show to completely abandon its newer characters.
Gary Cole’s Alden Parker remains part of the current NCIS team, alongside Sean Murray’s Timothy McGee, Wilmer Valderrama’s Nick Torres, Katrina Law’s Jessica Knight and Brian Dietzen’s Jimmy Palmer.
That means Tony is entering a team that has evolved considerably since he left.
This is not 2016 anymore.
McGee is now a veteran agent rather than the younger field agent who once worked alongside Tony. Torres and Knight represent a different generation of the team. Parker has his own leadership style and history. The relationships inside the bullpen have changed.
Tony’s presence therefore creates an unusual dynamic.
He knows the institution.
He understands the culture.
He remembers people and traditions that some of the newer characters never experienced.
And yet, he is also an outsider now.
That contradiction could give Season 24 plenty of dramatic material.
Tony may know exactly how the old NCIS worked, but that does not automatically mean he knows how the current team works.
In fact, that could become the point.
His return gives the writers an opportunity to explore what happens when someone from the franchise’s past walks into its modern era.
Reason No. 2: Tony Has Changed Since We Last Saw Him
The second major reason is arguably even more important for the story itself.
Tony has changed.
When audiences last knew him primarily as an NCIS agent, he was defined by his jokes, confidence, flirtatious personality and sometimes reckless behavior. His emotional development happened gradually over the course of the series, particularly through his relationship with Ziva and his bond with the team.
But Tony’s life after NCIS forced him into another role: father.
That changed the character.
His relationship with Ziva and their daughter Tali gave Tony responsibilities that were fundamentally different from those he had inside Gibbs’ team.
NCIS: Tony & Ziva gave Weatherly another opportunity to portray that version of the character, and his Season 24 return can build upon that development rather than pretending the intervening years never happened.
Weatherly has specifically credited the Paramount+ series with helping shape the Tony who is now returning to the original show.
That creates an interesting question for Season 24:
What happens when the old Tony meets the current NCIS?
The answer may not simply be another round of jokes and nostalgic references.
It could be a story about a man who has already moved into another chapter of his life being pulled back toward a part of his identity he thought he had left behind.
The Salus Mondiale Connection Changes Everything
The decision to make Tony’s return connected to his private security company is especially useful.
Rather than making Tony an NCIS agent again immediately, the show gives him an independent professional identity.
He is arriving in Washington because of business.
That means his involvement with NCIS can develop naturally.
The Season 24 premiere establishes that Tony is opening a satellite office for Salus Mondiale, while the NCIS team is investigating a threat against the Secretary of the Navy. His expertise becomes relevant to the case, giving him a believable reason to work alongside the team.
This is important because Tony’s professional experience outside NCIS can be used to show how much he has developed.
He is not returning as a museum piece.
He is returning with new skills, new responsibilities and a different perspective.
That could also allow the show to create tension between Tony and the current team.
McGee, for example, knows Tony extremely well. Their history gives the two characters an immediate foundation.
But Torres and Knight do not share that same history.
For them, Tony is essentially a legendary former agent walking into their workplace.
That creates opportunities for humor, awkwardness and even professional disagreement.
And Parker may have the most interesting relationship of all with Tony because he occupies a position of authority that Gibbs once held.
Tony has spent years working outside the NCIS hierarchy.
Now he is walking back into a world where someone else is leading the team.
Tony and McGee Could Be One of the Season’s Emotional Highlights
If Season 24 wants to use Tony’s return for more than nostalgia, his relationship with McGee is an obvious place to start.
Sean Murray’s McGee is one of the few characters remaining from Tony’s original era.
Their friendship represents continuity.
McGee remembers the Tony who worked alongside Gibbs and Ziva. He remembers the early days of the team. He also experienced Tony’s departure firsthand.
Now Tony is suddenly back.
The two men are not simply coworkers anymore. They are survivors of an earlier version of NCIS.
That could give their scenes a different emotional weight from Tony’s interactions with newer characters.
The premiere’s storyline involving McGee’s son also makes Tony’s timing particularly interesting. CBS has revealed that the opening episode deals with the fallout from a shooting involving McGee’s son while the team handles another threat. Tony arrives at precisely the moment McGee’s personal and professional worlds are colliding.
That gives Tony an immediate connection to the central story.
It also reinforces how much McGee’s world has changed.
The young agent Tony once knew has become a father and a senior member of the team.
In a strange way, Tony is coming home to find that everyone else has grown up too.
And Then There Is Ziva
Of course, no discussion of Tony DiNozzo’s return can completely avoid Ziva.
Cote de Pablo’s Ziva remains one of the most important relationships in Tony’s story, and the two characters were recently brought back together through NCIS: Tony & Ziva.
That does not automatically mean Ziva will appear in Season 24.
CBS has not announced a Ziva appearance in the Season 24 premiere, and the official storyline focuses on Tony’s arrival in Washington and the new case facing the NCIS team.
But Tony’s history with Ziva naturally creates questions.
Could she appear later?
Could the Tony & Ziva storyline affect Tony’s decisions?
Could the new NCIS season become another chapter in their family’s story?
Those remain separate from what CBS has officially confirmed.
What is clear is that Tony no longer exists as the same character he was when he left the original series. His relationship with Ziva and their daughter is part of his established history now, and that history can inform how he behaves in Washington.
CBS Is Building a Larger NCIS Universe
There is also a bigger franchise strategy behind all of this.
CBS has been increasingly willing to connect its NCIS shows through returning characters, crossovers and shared mythology.
Weatherly’s return comes alongside other major franchise developments, including Mark Harmon’s ongoing presence in NCIS: Origins and the expansion of the universe through NCIS: New York. Weatherly himself has discussed the possibility of more crossover opportunities involving other NCIS actors.
That creates a fascinating possibility for the future.
Tony could become a bridge between different corners of the franchise.
He has history with the original NCIS team.
He has a direct connection to Ziva.
He has now established Salus Mondiale.
And Weatherly has already demonstrated that Tony can exist successfully outside the traditional NCIS environment.
The character therefore has more flexibility than he did a decade ago.
He can be an investigator.
He can be a consultant.
He can be a private-security expert.
He can be a father.
And he can still be Tony DiNozzo.
That versatility may be exactly why CBS is bringing him back now.
The Nostalgia Is Real — But It Is Not the Whole Story
It would be easy to look at Weatherly’s return and call it a nostalgia play.
And certainly, nostalgia is part of it.
CBS knows that Tony DiNozzo is recognizable. The network knows viewers remember his partnership with Gibbs, his relationship with Ziva and his friendship with McGee.
But the current setup suggests the writers are attempting to do more than recreate the past.
Tony’s return has a contemporary storyline.
He has a new career.
He has a family.
He has changed.
And the NCIS team has changed too.
That distinction could make the comeback much more interesting.
The goal is not necessarily to recreate Season 5.
Instead, Season 24 can ask what Tony DiNozzo looks like after nearly a decade away from the organization that helped define him.
What Mark Harmon Represents in This New Era
The Mark Harmon connection ultimately says something important about the broader NCIS franchise.
Gibbs is still one of the defining figures in the show’s history. Harmon’s return to NCIS: Origins gives viewers access to a version of that character while allowing the franchise to explore his past. CBS has confirmed that Harmon will appear throughout Season 3 as part of a present-day mystery connected to Gibbs’ history.
Weatherly’s return works differently.
Tony is not being placed in a prequel.
He is coming back to the present.
That means audiences get to see what happens when one of the original show’s major characters encounters the modern NCIS team.
Gibbs represents the franchise looking backward to understand where its central character came from.
Tony represents the franchise bringing part of its past directly into its current story.
Those are two very different approaches to nostalgia.
And having them happen during the same broader television season makes the timing especially notable.
Season 24 Could Become a Reunion Without Becoming a Reboot
The biggest question surrounding Tony’s comeback is therefore not whether audiences remember him.
They obviously do.
The real question is what the writers intend to do with him.
CBS has already confirmed that Weatherly’s return will be part of a season-long arc rather than a one-episode guest appearance.
That gives the story room to breathe.
Tony does not have to arrive, solve a case, exchange a few jokes with McGee and disappear again.
Instead, the show can explore his new business, his relationship with the current NCIS team and the unresolved emotional connections created by his past.
It also gives Weatherly an opportunity to portray the character at a different stage of his life.
That is arguably the most compelling aspect of the comeback.
Tony DiNozzo returning to NCIS is exciting because viewers remember who he was.
But Tony DiNozzo returning after everything that has happened since he left could be much more meaningful.
The Premiere Sets the Tone
The Season 24 premiere, titled “Wayward Son,” is scheduled for Tuesday, October 6, at 8 p.m. ET/PT on CBS and Paramount+. The episode introduces Tony’s return while the team deals with the fallout from the shooting involving McGee’s son and investigates a threat to the Secretary of the Navy.
That is a packed setup.
It places Tony directly inside an active NCIS investigation instead of treating his arrival as a standalone reunion.
And the title itself feels appropriate for a character who has spent years away from the organization.
Tony is coming back, but he is not necessarily coming back to the same place.
The people are different.
The leadership is different.
The stakes are different.
And Tony himself is different.
That is where the two big reasons for his return ultimately come together.
CBS is leaning into the enduring power of the NCIS legacy, especially at a moment when Mark Harmon is once again appearing as Gibbs in NCIS: Origins. At the same time, the writers have a chance to use the Tony who emerged from years away from the flagship series — a more experienced character whose life with Ziva and Tali changed his priorities.
The nostalgia gets viewers through the door.
The character development gives Tony a reason to stay.
And that may be the real story behind Michael Weatherly’s return.
Tony DiNozzo is coming back to NCIS — but the version of Tony walking through those doors in Season 24 is not the same man who walked out in 2016.
