The Shocking Departures: Why Scott Forrester and Jamie Kellett Left

Season 3 of FBI: International was defined by the sudden and significant exits of two of its original stars, Luke Kleintank and Heida Reed. These departures created the massive void in leadership that Jesse Lee Soffer is now filling.

The first major exit was Heida Reed, who played Special Agent Jamie Kellett, the team’s second-in-command, since the series premiere in 2021. Kellett’s departure was shown in the Season 3 premiere, where her character was transferred back to Washington D.C. Her exit was a significant emotional blow to the team, particularly to her on-again, off-again romantic interest, Scott Forrester.

The second, and perhaps most impactful, departure was Luke Kleintank, who played Supervisory Special Agent Scott Forrester, the original head of the International Fly Team. Kleintank announced his exit midway through Season 3, stating that he was leaving to spend more time with his family. His character’s storyline was given a dramatic conclusion, leaving the team without its founding leader and setting the stage for the arrival of Agent Wesley Mitchell. The loss of both original leads has fundamentally reset the series' core relationships and chain of command.

Behind the Scenes: Filming Locations and The Dick Wolf Universe Connection

The topical authority of FBI: International is heavily reliant on two key elements: its connection to the successful Dick Wolf television empire and its authentic European setting.

The Dick Wolf Crossover and Procedural Universe

FBI: International is the third series in the highly successful FBI franchise, which is executive produced by Emmy Award winner Dick Wolf. This shared universe includes the flagship series FBI and the spin-off FBI: Most Wanted. The casting of Jesse Lee Soffer, a veteran of the *Chicago P.D.* (a separate but related Dick Wolf franchise), as the new lead, Wesley Mitchell, is a strategic move. It not only brings a familiar face to the franchise but also strengthens the narrative ties across the entire procedural universe, a concept known as the "Wolf Universe." This often allows for seamless crossover events, where characters from one show appear in another to tackle a shared threat.

Authentic European Filming Locations

What sets FBI: International apart from its New York-based counterparts is its commitment to filming on location across Europe. The show is primarily based and filmed in Budapest, Hungary, which serves as the Fly Team’s headquarters. The use of authentic locations is a massive draw for viewers, providing a cinematic backdrop for the intense investigations. The production team frequently travels, showcasing a variety of stunning European cities and landmarks.

• Budapest, Hungary: The primary base of operations and a frequent backdrop for episodes.
• Pula, Croatia: Scenes have been set against historical sites, including the majestic Roman amphitheater.
• Paris, France: The romantic streets and iconic landmarks of Paris have served as key filming locations for various missions.
• Swiss Alps: Season 4 plot details have referenced missions in the Swiss Alps, suggesting a continued commitment to diverse European settings.

This dedication to on-location filming ensures the series maintains a fresh, unique aesthetic compared to other procedurals, making the International Fly Team’s work feel truly global and high-stakes.

What to Expect from the New Team Dynamic in Season 4

The transition from Scott Forrester to Wesley Mitchell is the central narrative focus for Season 4. Forrester was known for his intense, often rule-bending, and protective leadership style, deeply connected to his troubled past. Mitchell's introduction as a "charming and rakish" Supervisory Special Agent suggests a potentially lighter, yet equally effective, approach to leading the Fly Team.

The remaining core team—Raines, Vo, and Smitty—are now the veteran agents who must adapt to their new boss. The dynamic between the highly disciplined Vo, the financially astute Raines, and the experienced Europol Agent Smitty will be crucial in establishing the new team chemistry. Fans can anticipate that the new leader will be tested early on, forcing the remaining agents to decide where their loyalties lie and how they can best support Mitchell's leadership while continuing their essential work protecting American interests across the continent.

The show's commitment to exploring complex international cases, from serial killers to fake death plots, ensures the action remains high-octane. With a new leader and a renewed sense of purpose, FBI: International is poised to deliver its most transformative and exciting season yet.
