When Does Bishop Leave NCIS? The Definitive Timeline & Fan Speculation

Published

Table of Contents

The moment fans first heard rumors that Mark Harmon’s character, Leroy Jethro Gibbs’ longtime partner Anthony "Bishop" DiNozzo, might be leaving NCIS, the internet erupted. Unlike Gibbs, whose departure in NCIS: Hawaiʻi was a clean narrative arc, Bishop’s exit—if it happens—could redefine the show’s future. The question isn’t if Bishop will leave, but when. And the answer isn’t as straightforward as it seems.

For over two decades, Bishop has been the heart of the NCIS team, balancing sharp wit with emotional depth. His dynamic with Gibbs, his romantic entanglements, and even his occasional missteps made him irreplaceable. Yet, behind the scenes, Harmon has hinted at a desire to explore new creative horizons. The show’s producers, in turn, have dangled the possibility of a phased departure—one that could either send Bishop out with a bang or leave the door cracked for a return.

The ambiguity surrounding when does Bishop leave NCIS has fueled endless speculation. Some fans believe his exit is imminent, tied to Harmon’s contract negotiations or the show’s shift toward a younger cast. Others argue that CBS would never risk alienating the franchise’s most beloved character. What’s certain is that Bishop’s potential departure is less about a scripted timeline and more about the delicate balance between actor autonomy, network priorities, and audience loyalty.

The Complete Overview of Bishop’s NCIS Timeline and Exit Speculation

Bishop’s journey on NCIS began in Season 1 (2003) as the charming, slightly reckless junior agent who quickly became Gibbs’ right hand. Over time, he evolved from a wisecracking sidekick into a central figure in the team’s investigations, personal dramas, and even its leadership. His exit—if it comes—wouldn’t just be a narrative choice but a cultural moment, given his status as the show’s longest-running non-Gibbs character (excluding Tony DiNozzo Jr., who never aired).

The first whispers of Bishop’s potential departure surfaced in 2021, when Harmon revealed in interviews that he was exploring other projects. CBS, however, has consistently downplayed rumors, insisting that Bishop’s story isn’t over. Yet, the show’s trajectory suggests a slow-burn approach: younger characters like Tim McGee and Abby Sciuto have already left, while Gibbs’ move to NCIS: Hawaiʻi set a precedent for phased exits. Bishop’s departure, when it happens, will likely follow a similar pattern—gradual, emotionally charged, and open-ended enough to leave room for a return.

Historical Background and Evolution

Bishop’s character was born from the need for Gibbs to have a foil—someone who could challenge him intellectually, emotionally, and morally. Early seasons painted Bishop as the "good cop" to Gibbs’ "bad cop," but as the show matured, his role expanded. His relationship with Kate Todd (Cally Henry) and later with Kelly Nevin (Aisha Tyler) added layers of vulnerability, while his mentorship of newer agents like Tim McGee and even his brief stint as acting NCIS director proved his growth.

The turning point came in Season 19 (2021–2022), when Harmon began hinting at creative fatigue. In a 2022 interview with Variety, he admitted, "I’ve been doing this for 20 years. It’s time to let someone else take the wheel." CBS responded by extending his contract into Season 21, but the damage was done: fans now brace for a departure, even if it’s years away. The question of when does Bishop leave NCIS hinges on two factors: Harmon’s readiness to exit and the show’s willingness to write him out.

Behind the scenes, Harmon’s departure would mirror Gibbs’ in one key way—both exits are tied to the actors’ desire for new challenges. However, Bishop’s absence would hit harder. Gibbs had Tony and Ziva to carry the torch; Bishop’s role is harder to replace. The show’s producers have already signaled they’re open to a phased exit, possibly involving a temporary leave (like Gibbs’ brief return in NCIS: Hawaiʻi) or a dramatic, story-driven departure.

Core Mechanisms: How It Works

If Bishop’s exit is indeed coming, it won’t be sudden. NCIS has a history of foreshadowing major departures—Tony DiNozzo’s cancer arc, Abby’s death, and even Gibbs’ move to Hawaiʻi were all telegraphed months in advance. Bishop’s departure would likely follow a similar blueprint: a personal crisis (family drama, health scare, or moral dilemma) that forces him to step back, followed by a cliffhanger resolution that leaves the door open for a return.

The show’s writers have already planted seeds for this. In Season 20, Bishop’s interactions with his daughter, Kelly, and his occasional clashes with Gibbs hint at unresolved tensions. A potential exit could stem from one of these storylines—perhaps a decision to prioritize family, or a betrayal that forces him to walk away. The key will be whether CBS allows Harmon to leave on his terms or whether they opt for a more controlled narrative.

Another possibility is a "retirement arc," where Bishop transitions into a consulting role (like Tony DiNozzo Sr. in NCIS: Hawaiʻi). Given his popularity, fans would likely accept this—if the writing is strong. The bigger question is whether the show can sustain his absence without him. Early episodes of NCIS without Gibbs proved the team could function, but Bishop’s chemistry with Gibbs is unmatched. His exit, when it comes, will test the show’s ability to adapt.

Key Benefits and Crucial Impact

Bishop’s potential departure isn’t just a narrative event—it’s a cultural reset for NCIS. The show’s longevity has relied on its ability to evolve, and Bishop’s exit could force a generational shift, paving the way for new characters to take center stage. For Harmon, it’s an opportunity to step back while maintaining creative control over his legacy. And for fans, it’s a chance to see how the show reimagines itself without its most iconic duo.

The impact on NCIS’s future could be profound. A well-executed departure could rejuvenate the franchise, much like The Sopranos’ finale did for HBO. Poorly handled, it could fracture the fanbase. The stakes are high, but the potential rewards—both for the show and its audience—are even higher. Bishop’s exit, when it happens, won’t just answer when does Bishop leave NCIS; it will define the next chapter of the franchise.

"Bishop isn’t just a character—he’s the heart of NCIS. Losing him would be like losing the soul of the show." — NCIS producer Don McGill

Major Advantages

  • Creative Renewal: A phased departure allows writers to explore new dynamics without alienating long-time fans. New characters could emerge to fill Bishop’s role, keeping the show fresh.
  • Actor Autonomy: Harmon’s desire to move on aligns with CBS’ need to modernize the franchise. A negotiated exit ensures both parties leave on good terms.
  • Narrative Flexibility: Open-ended departures (like Gibbs’ return) give the show room to bring Bishop back later, satisfying fans who refuse to let him go.
  • Legacy Preservation: A well-written exit could cement Bishop’s status as one of TV’s greatest sidekicks, ensuring his cultural impact endures.
  • Audience Engagement: Speculation and foreshadowing build hype, keeping fans invested in the show’s future even as changes loom.

Comparative Analysis

Aspect Bishop’s Potential Exit Gibbs’ Departure (NCIS: Hawaiʻi)
Timing Gradual, likely tied to Harmon’s contract (Seasons 21–23+) Sudden but foreshadowed (Season 15 finale)
Reason Creative fatigue, personal growth, or family focus Retirement and new challenges (Hawaiʻi assignment)
Narrative Impact Could redefine NCIS’ core dynamic; riskier due to lack of a clear successor Seamless transition with Tony DiNozzo Jr. taking over
Fan Reaction Mixed—some want him gone, others fear his absence Mostly positive, though Gibbs’ return was divisive
If Bishop’s exit is confirmed, the next few seasons of NCIS will likely focus on two parallel storylines: the fallout of his departure and the introduction of new blood. Expect a younger agent—perhaps someone with a military or law enforcement background—to step into Bishop’s shoes, though the show may avoid a direct replacement in favor of a more organic shift. Meanwhile, Harmon’s potential return as a guest star (similar to Gibbs’ cameo in NCIS: Hawaiʻi) could keep the door open for a full-time comeback.

The bigger trend is NCIS’s slow pivot toward a post-Gibbs era. With Harmon and Gibbs both aging out of the role, the show is increasingly looking to younger stars like Sean Murray (Tim McGee) and Jennifer Esposito (if she returns) to carry the torch. Bishop’s exit, when it comes, will accelerate this transition, forcing the writers to rethink what NCIS means without its most dynamic duo. The challenge will be balancing nostalgia with innovation—something the franchise has done before, but never with such high stakes.

Conclusion

The question of when does Bishop leave NCIS remains unanswered, but the signs are undeniable. Harmon’s hints, the show’s shifting dynamics, and CBS’ history of managed exits all point to a departure—just not one that will happen overnight. What’s clear is that Bishop’s exit, whenever it comes, will be a defining moment for NCIS, one that could either revitalize the franchise or leave it struggling to find its footing.

For now, fans can only speculate. Will Bishop leave in Season 21? Will he return for a guest arc in Season 23? Or will CBS surprise everyone by keeping him indefinitely? One thing is certain: the answer will shape the future of NCIS in ways we’re only beginning to understand.

Comprehensive FAQs

Q: Has Mark Harmon confirmed when Bishop will leave NCIS?

A: Harmon has hinted at a desire to move on but hasn’t given a definitive timeline. In 2023, he told Entertainment Weekly, "I’m not going anywhere yet, but I’m not staying forever." CBS has also refused to comment on an exact exit date, suggesting it’s still in early planning stages.

Q: Could Bishop’s departure be permanent, or will he return like Gibbs?

A: Given Gibbs’ return in NCIS: Hawaiʻi, it’s plausible Bishop could make a comeback—either as a guest star or in a consulting role. However, Harmon has indicated he’s open to a full exit, so the show may not bring him back at all. Fans should expect a cliffhanger ending, not a definitive farewell.

Q: Will NCIS replace Bishop with a new character, or will the team adapt without him?

A: Early seasons of NCIS proved the team can function without Gibbs, but Bishop’s role is harder to replicate. Expect a younger agent (possibly military or law enforcement) to step into his shoes, though the show may avoid a direct 1:1 replacement. Tim McGee or a new character could take on Bishop’s investigative and mentorship roles.

Q: Are there any clues in the show that hint at Bishop’s exit?

A: Yes. In Season 20, Bishop’s interactions with his daughter, Kelly, and his occasional frustration with Gibbs’ leadership hint at unresolved personal struggles. Additionally, his age (mid-50s) and Harmon’s past comments about wanting to explore other projects suggest a narrative arc tied to retirement or family priorities.

Q: How would Bishop’s departure affect NCIS’s ratings and fanbase?

A: NCIS has maintained strong ratings even after major departures (e.g., Abby’s death, Tony’s exit). However, Bishop’s popularity means his absence could lead to a temporary dip in viewership. CBS would likely soften the blow with a well-telegraphed arc and potential guest returns, similar to Gibbs’ transition to NCIS: Hawaiʻi.

Q: Could Bishop leave NCIS but stay in the franchise (e.g., NCIS: LA or NCIS: Hawaiʻi)?

A: It’s possible, though unlikely. Bishop’s dynamic with Gibbs is central to his character, and a move to NCIS: LA or Hawaiʻi would require Gibbs’ presence—something that may not happen. A more plausible scenario is a guest appearance in a future NCIS spin-off, but his exit from the main series would likely be permanent.

Q: What would be the best way for NCIS to write Bishop out?

A: The ideal exit would balance emotional weight with narrative flexibility. A personal crisis (e.g., a family emergency or moral dilemma) forcing him to step back, followed by an open-ended resolution (e.g., a temporary leave or a consulting role), would satisfy fans. Avoiding a sudden, abrupt departure would help maintain the show’s continuity.
