Airing on Tuesday, December 17,FBI: Internationalseason 4, episode 8 is titled “You’ll Never See It Coming,” and serves as the show’s fall finale. It will see Beau Knapp’s Greg Csonka return when the star witness in the case against him is “beaten to death in a Budapest prison before he can testify.” The antagonist first appeared in the season 4 premiere and vowed to get revenge on the Fly Team leader, who is responsible for his arrest. Therefore, it was only a matter of time before the plotline came full circle and forced Wes to revisit what—or who—Csonka cost him.

Joining the team in their attempt to uphold Csonka’s conviction is Agent Tyler Booth, played byStation 19alumni Jay Hayden. When speaking withScreenRantabout his character’s relationship with Wes, Hayden confirms that Tyler does have an influence on his former colleague. As Wes struggles to control his emotions in the fall finale,the temporary Fly Team agent may push him to choose vengeance over justice.Check out Hayden’s full quote below:

ScreenRant: The recent episode makes the team wonder if Wes' friendship with Tyler affects his decision-making. What do you think?

Jay Hayden: Yes. I think because they were partners for so long, they were equals for so long, and had each other’s back, and did a lot of stuff back then and were friends—it’s very hard now that the dynamic has changed to change that. They’re still operating as if, even though the titles have changed and the jobs are different. It’s going to keep clashing.

Well, Csonka is coming back in the mid-season finale, and he’s going after Vo…

Jay Hayden: There’s a perfect example. As it gets more personal for Wes, will the counseling from Tyler be positive or maybe lead it to a more negative place? Maybe the devil on his shoulder—that voice gets louder and louder. Now he’s got someone in his ear saying, “Whatever it takes is whatever it takes. Who cares? No one’s going to know.”

Wes officially joins the Fly Team after his partner is killed by Csonka in the season 4 premiere. Since Mike’s death,Vo has acted as a pillar of support for her former training agent, and their connection remains a surprising highlight of the show.In the previewforFBI: Internationalseason 4, episode 8, Wes comes face-to-face with Csonka before he is transported. The prisoner convoy is intercepted, and Vo goes down after a shootout ensues.
