WARNING! SPOILERS ahead for FBI: International season 4, episode 22, "Gaijin."
FBI: International season 4, episode 22, titled "Gaijin," leaves several questions open, even though the episode is the series finale. FBI: International season 4 wasn't intended to be the procedural's final season. It introduced Wes Mitchell (Jesse Lee Soffer) as the new leader of the Fly Team, who was meant to replace Scott Forrester (Luke Kleintank), who had disappeared near the end of season 3 and was said to be helping his fugitive mother escape.
Unfortunately, FBI: International became one of the shows CBS canceled in 2025. The announcement was made in March, two months before production ended, and the finale aired, leading to widespread speculation about what would happen in the wrap-up. However, the final episode focuses on Wes' solo adventure in Tokyo, offering no wrap-up for him or any other character, instead presenting cliffhangers that will never be resolved now that the procedural has ended.
9 What Happens To The Fly Team?
It's Unclear Whether The Team Still Exists And Who Is Leading It
There was widespread speculation that FBI: International's season 4 ending would include the Fly Team being disbanded. This would have ended the series, and earlier episodes suggested this would be the case. Several seeds were planted, suggesting Wes would return to the United States, and Vo and Raines were competing for a job elsewhere. Thus, it seemed the team would lose at least two key members, and the FBI might decide to cease operations in Budapest.
8 Is Wes Leaving Permanently?
It Wasn't Clear If He Was Moving Back Home Or Making A Short Visit

FBI: International's final scene is Wes finding his half-sister, Delilah, as she is walking in a secluded area and introducing himself as her brother. While it's clear he decided to try to forge a relationship with her, there is still ambiguity as to Wes' fate. He might have decided to quit the Fly Team and move back to the States to spend time with Delilah, but it's equally possible he wanted to visit her before returning to Budapest.
It would have made sense for Wes to leave permanently and allow Vo to take over the team, but that isn't made explicit in this final scene.
7 Who Got The G14 Job?
The Scene Cuts Off Without Revealing The Answer

The non-ending of Vo and Raines' storyline is one of the most disappointing aspects of the FBI: International finale. This story has been built up over weeks, with Wes telling Vo and Raines about this job opportunity and warning them that they'll have to compete against each other. Instead of giving the audience an answer of who was chosen, the series finale leaves it open-ended.
It's clear this story was intended to have a cliffhanger that would be resolved in FBI: International season 5.
The best solution would have been for Raines to get it so Vo could take over the Fly Team after Wes left, but unfortunately, this will never be confirmed.
6 What Happened With Tate And Wes' Relationship?
It Began, Then Fizzled Out With No Resolution
There was no real opportunity for any Tate/Wes scenes in the series finale because Wes was in Tokyo while the rest of the team stayed in Budapest and occasionally helped get him needed intel. Tate and Wes didn't interact much and had no personal conversations. Thus, there was no closure to their relationship arc, making it feel pointless for the series to have started so close to the final episode.
5 Can Reiko Join The Fly Team?
She Lost Her Position With The Japanese Police
The final two episodes introduced a new character, Japanese police officer Reiko Isokawa (Yoriko Haraguchi). Reiko initially resisted telling the Fly Team the truth about a serial killer they were searching for because she didn't want her country to look bad. However, she was Wes' partner once he reached Tokyo, implying this character was meant to be more than a one-off. Furthermore, Wes encouraged her not to give up on fighting for justice when she was fired from the Japanese police force at the end of the case.
Thus, it seems likely that the intention was for her to join the Fly Team after losing her position in Japan. However, she was left in limbo, with no job and nothing more than a pep talk from Wes before he left for the United States and the finale ended.
4 What Was Smitty's Fate?
The Interpol Agent Barely Appears In The Finale
Although she technically wasn't part of the Fly Team, Smitty was one of FBI: International's most recognizable characters. She often worked with the team, using her Europol connections to help solve cases, and had a strong personal storyline near the end. For these reasons, she deserved far more than she got in the finale. To be fair, most of the Fly Team got the short end of the stick while Wes was in Tokyo, but Smitty's absence was particularly noticeable.

There Wasn't Enough Air Time For The Other Members To Be Sure

The majority of the episode was dedicated to Wes' attempts to find a kidnapped American in Tokyo before she became a killer's next victim, with the rest of the Fly Team playing a role while monitoring the situation from Budapest. During many of the scenes in which Wes talked with his team, Vo (Vinessa Vidotto) appeared to be in charge of the Fly Team. However, it was impossible to tell if this was the case.
Instead, they got cameo appearances where they relayed information or followed Wes' directions to get intel. This was one of the most disappointing aspects of the finale, as it robbed the audience of the opportunity to see what the Fly Team looks like without Wes there to lead.
2 Will There Be Any Members Of The Fly Team Appearing In The CIA Spinoff?
It's Possible, But Nothing Has Been Said Yet
Although FBI: International is finished, the members of the Fly Team could theoretically appear in CIA, an offshoot of FBI premiering in the fall of 2025. CIA focuses on cases involving crimes against the United States, often involving international espionage. Thus, it is a ready-made sequel for FBI: International, and it would make sense to fold some of the Fly Team into the new series.
That said, the finale didn't give any indications as to whether this would happen.
It's also an open question whether the new position Raines and Vo competed for was a position that would qualify them to work with the CIA in the new series.
1 What FBI: International Season 5 Was Going To Be
The Cliffhangers Offer Some Clues
FBI: International could have done an emotional story about Delilah rejecting Wes and Wes refusing to give up. Similarly, the Fly Team would likely have lost either Raines or Vo and gained Reiko, and Tyler Booth's (Jay Hayden) reappearance suggests he would have had a bigger role in the new season. It's disappointing that these story threads will never be followed up on, especially since the writers squandered the opportunity to wrap up the series to include cliffhangers that will now have no resolution.
