He plays Supervisory Special Agent Wesley “Wes” Mitchell, a new character. Soffer is not reprising his Chicago P.D. role of Detective Jay Halstead, and the character is not a continuation of Halstead’s story.
Who took over from Scott Forrester
Kleintank played Supervisory Special Agent Scott Forrester from the series debut through Season 3. In April 2024, TVLine reported that Kleintank was leaving the show, and he attributed the decision to family. In a statement he said: “This decision is driven by my unwavering commitment to my family, whose love and well-being are paramount in my life.” (TVLine, April 23, 2024)

Forrester’s exit was written into the show rather than handled off-screen. He went AWOL, and it was later revealed that he had joined his fugitive mother, Angela Cassidy, and was on the run with her.
The new team leader: Wes Mitchell
In June 2024, TVLine reported that Soffer had joined FBI: International as a Season 4 series regular to fill the gap left by Kleintank. At that point the character was not named. The report stressed that Soffer would play a new character rather than Halstead, even though he is best known for the Halstead role on Chicago P.D. (TVLine, June 20, 2024)

Season 4 names that character as Supervisory Special Agent Wesley “Wes” Mitchell, the new leader of the International Fly Team. The show’s premise, as described by its production company, is a Budapest-based International Fly Team travelling through Europe to protect Americans. (Wolf Entertainment, series page)
Why the One Chicago connection does not carry over
The two franchises share a universe, which is why the question comes up. Soffer’s career on Chicago P.D. makes Halstead the first association many viewers make. But the FBI: International role is a separate character with his own backstory and place on the team. Readers should not assume that Halstead transferred to the international unit, or that the Season 4 storyline picks up from Chicago P.D.
Tyler Booth is a different kind of addition
Jay Hayden is the source of most of the confusion. He appears in Season 4 as Agent Tyler Booth, who is not a team leader. In a December 2024 TV Insider interview, Hayden described Booth as one of Wes Mitchell’s close friends and said Booth is temporarily placed with the Fly Team. Hayden said: “He’s worked with Wes Mitchell previously to Wes’s coming over to the Fly Team.” He also described Booth’s approach: “He’s more concerned about getting the job done.” (TV Insider, December 5, 2024)
Three Season 4 roles compared
| Character | Actor | Status in Season 4 | Relationship to earlier roles | Narrative function |
|---|---|---|---|---|
| Scott Forrester | Luke Kleintank | Departed; series regular through Season 3 | Original team leader from the series debut | Written out after going AWOL and joining his fugitive mother, Angela Cassidy |
| Wes Mitchell | Jesse Lee Soffer | Series regular; leader of the International Fly Team | New character, not Jay Halstead from Chicago P.D. | Replaces Forrester as the team’s leader |
| Tyler Booth | Jay Hayden | Temporary placement with the Fly Team | Described as one of Wes Mitchell’s best friends | Brought in alongside Wes; not a leadership role |
What the sources do and do not establish
The reporting cited here covers Kleintank’s exit, Soffer’s casting, and Hayden’s Season 4 description. Those sources establish that Wes Mitchell is the team-leader replacement and that Booth is a separate Season 4 addition. The sources do not address how the character’s arc develops beyond what is described above, and they say nothing about later seasons. Check the current cast listing for FBI: International before assuming who leads the team in any season after Season 4.
Kleintank’s exit, Soffer’s casting, and Booth’s placement were all reported by named outlets at the time, so the core answer is well sourced. What remains uncertain is anything after those announcements.
Also check your viewing platform for the Season 4 episode listings, as availability varies by region.
FBI: International is a spin-off of FBI, and the team name and mission described above reflect the Season 4 premise as Wolf Entertainment presents it.
Readers who want the simplest version can leave with this: Soffer is the team-leader replacement as Wes Mitchell, Wes is not Halstead, and Booth is a temporary Season 4 addition to the Fly Team.

Finally, the Season 4 premise centres on protecting Americans abroad, which is why the team is based in Budapest and travels across Europe.
The Season 4 leadership change is the single most important casting fact for this season.
