Booth Returns to the States for a New Role


Ultimately, Smitty’s idea of resigning emerges as a pragmatic solution. By stepping down, she would alleviate the pressure on Booth’s promotion process, shifting the responsibility of the recommendation to Mitchell. However, Smitty’s decision, if enacted, would leave the Fly Team at a disadvantage, as her role is invaluable—acting as their liaison with European authorities.
In a turn of events, Wes refuses to accept Smitty’s resignation, claiming he never received her email. He also reveals that Booth has withdrawn from consideration for the GS-14 role, thereby deciding to return to the United States. Booth’s decision underscores his commitment to the team, prioritizing its strength over his personal aspirations.
Booth’s selfless act preserves the integrity of the Fly Team, which heavily relies on Smitty’s expertise and his ability to navigate the complexities of international law enforcement. His departure prevents another less-than-ideal exit within the franchise, concluding his storyline on a heartfelt note—reuniting with his daughter, symbolizing personal fulfillment beyond his career.
Why Booth’s Time with the Fly Team Was Always Temporary
Jay Hayden’s Role was Designed as Temporary

The nature of Booth’s exit was anticipated, as Jay Hayden has consistently been portrayed as a recurring guest star rather than a permanent cast member. His designation indicated that Booth’s presence in FBI: International was always meant to be brief, leading to the eventual conclusion of his character arc. Interestingly, the subplot surrounding Smitty’s resignation cleverly misled audiences, adding a layer of suspense to Booth’s departure.
Unlike fellow character Clay Voss from FBI, who met a grim fate, Booth’s conclusion was notably more tranquil. His story emphasized his status as a character embroiled in tension, hinting at his inability to mesh with the Fly Team’s dynamics long-term. This narrative arc suggested his tenure would be limited, aligning with the show’s overall storytelling strategy.

Uncertainty Surrounds His Next Steps

The future of Booth post-Fly Team remains ambiguous. As Mitchell remarks, Booth plans to return to South Carolina with his reputation restored and his personal life more stable. However, the specifics of his new position within the FBI remain unclear, which opens the door for potential storylines that could see Booth reunited with the Fly Team in future episodes, especially if circumstances allow for a crossover scenario.
Booth’s new role in South Carolina could facilitate guest appearances on FBI: Most Wanted, given the unit’s extensive travel in pursuit of fugitives across the U. S.While his return to FBI: International is plausible, it would necessitate a compelling narrative to justify his reappearance in Budapest.
