WHO’S STAYING AND WHO’S LEAVING? FBI Season 9 Finally Reveals Its Biggest Cast Changes

The countdown to Season 9 of FBI has officially begun, and fans are asking the question that accompanies every new season of a long-running drama: Who’s staying, and who’s leaving?

After eight seasons of high-stakes investigations, shocking twists, and unforgettable character moments, the hit CBS series is preparing for another chapter. With rumors swirling across social media and fan forums, viewers are eager to learn which familiar faces will continue protecting New York City and whether any major departures are on the horizon.

While CBS has not announced a sweeping cast overhaul, Season 9 is already generating discussion about the future of several key characters.

The Core Team Remains the Heart of the Show

One reason FBI has remained successful for so many years is its strong ensemble cast. The series has consistently balanced intense cases with character-driven storytelling, allowing audiences to connect with the agents behind the badges.

Many fans expect the show’s central figures to remain at the forefront of Season 9.

Among the most important members of the team are:

• Missy Peregrym as Maggie Bell
• Zeeko Zaki as Omar Adom “OA” Zidan
• Jeremy Sisto as Jubal Valentine
• Alana de la Garza as Isobel Castille

These characters have become the backbone of the series, and fans would be hard-pressed to imagine the show without them.

Missy Peregrym’s Future Continues to Spark Debate

No cast discussion would be complete without mentioning the ongoing speculation surrounding Missy Peregrym.

Over the years, temporary absences related to personal commitments have repeatedly fueled rumors that she might leave the series permanently. Each time, fans have worried about Maggie Bell’s future.

As Season 9 approaches, those questions continue.

However, there has been no official confirmation that Peregrym is exiting the show. In fact, many viewers expect Maggie to remain a central figure in upcoming storylines.

Given her importance to both the series and her partnership with OA, a permanent departure would represent a major change for the franchise.

OA Remains a Fan Favorite

If there is one character fans seem universally eager to see return, it is OA.

Played by Zeeko Zaki, the character has grown into one of the show’s most respected and beloved agents. His moral compass, determination, and partnership with Maggie have made him a cornerstone of the series.

Recent storylines have placed OA in increasingly challenging situations, suggesting there is still plenty of room for further development in Season 9.

For many viewers, FBI simply would not feel the same without him.

Leadership Faces New Challenges

Season 9 is also expected to continue exploring the leadership responsibilities carried by Jubal Valentine and Isobel Castille.

Both characters have frequently found themselves balancing professional obligations with personal struggles, creating some of the show’s most compelling storylines.

Their experience and authority remain essential to the operation of the New York Field Office.

As threats become more complex, their roles may become even more important.

Could New Faces Join the Team?

Long-running procedural dramas often introduce new characters to keep stories fresh.

While there has been no confirmation of major additions, fans are already speculating about the possibility of:

• New agents joining the field office.
• Guest stars receiving expanded roles.
• Crossovers with other FBI franchise characters.
• Temporary task-force members becoming permanent fixtures.

Fresh faces could provide new dynamics while preserving the show’s established foundation.

Why Cast Changes Matter

The cast of FBI has always been one of its greatest strengths.

Unlike some procedural dramas that focus primarily on weekly cases, FBI invests heavily in its characters. Viewers become attached to the agents, their relationships, and their personal journeys.

As a result, any cast change carries significant emotional weight.

A departure is not simply a production decision.

It affects storylines, partnerships, and the overall identity of the series.

What We Actually Know

Despite dramatic headlines suggesting massive shake-ups, the reality is that most reports remain speculative.

At the time of writing:

• CBS has renewed FBI for Season 9.
• No official announcement has confirmed the departure of any major series regular.
• Core cast members are widely expected to remain involved.
• Future casting announcements may emerge closer to the season premiere.

That means many rumors should be treated cautiously until confirmed by CBS or the actors themselves.

Looking Ahead

Season 9 represents another important milestone for one of television’s most successful crime dramas.

The series has built a loyal audience through strong storytelling, memorable characters, and compelling investigations. Maintaining that formula while continuing to evolve will be the challenge facing the creative team.

Whether new characters arrive, familiar faces depart, or unexpected twists reshape the field office, fans can expect plenty of suspense both on and off the screen.

For now, the biggest takeaway is simple: the future of FBI remains bright, and viewers will be watching closely to see which agents continue the mission when Season 9 finally arrives.

Until official announcements are made, the question of who’s staying and who’s leaving remains one of the most intriguing mysteries surrounding the next chapter of FBI.
