The Fly Team gets a new boss when Season 4 of FBI: International begins. The rest of the agents are introduced to him during a case.

Premiering on October 15, "A Leader, Not a Tourist" stars Chicago PD alum Jesse Lee Soffer as Supervisory Special Agent Wesley "Wes" Mitchell. The Fly Team meets him when his partner is gunned down in Los Angeles and the suspects flee to Budapest, sending Mitchell overseas. He'll be working with Vo (Vinessa Vidotto), Raines (Carter Redwood), Smitty (Eva-Jane Willis) and Tate (Christina Wolfe). Check out photos of Wes and the team below.

Wes comes after the departure of Luke Kleintank’s Scott Forrester. Kleintank’s final episode came towards the end of Season 3, and it was in the finale that Forrester was officially written out. His mother’s name was on an intake form at a Russian prison, and she swapped identities with an American citizen and former military medic (Teri Polo) who had been caught up in the war in Ukraine and had been arrested by Russia. Forrester could only get one of them out, and he knew his team would follow the leads and catch Tess.

At the end of the finale, the team received a tip on Forrester's location – 30 miles west of the Bering Strait, possibly toward Alaska – but the agency's liaison with the NSA, Brian Lange (Colin Donnell), told them to delete the information and leave him and Angela alone. (Before they even knew his location, Forrester's security had been revoked and he had no future with the FBI.)
