Will Trent Season 3 cast and character guide: Who plays whom in the ABC drama? 

Will Trent returns to ABC for a new set of episodes, and season three brings the familiar team back while adding a few notable faces. Ramón Rodríguez continues in the title role, joined by Erika Christensen, Iantha Richardson, Jake McLaughlin, and Sonja Sohn, the core group that drives the show’s investigations.

This season also adds Gina Rodriguez as a series regular, stepping into a legal role that changes how the team works on cases and in court. The series follows Special Agent Will Trent as he solves crimes with the Georgia Bureau of Investigation while navigating his complicated past and relationships.

The concise cast list below explains who plays whom, why those roles matter to the stories this season, and how the new additions shift the show’s focus toward courtroom drama as well as fieldwork.

The main cast of Will Trent

Ramón Rodríguez plays Special Agent Will Trent, the GBI investigator at the center of the series; he is a detective with dyslexia and a challenging past. Erika Christensen is Angie Polaski, a detective who often works with Trent and shares a complicated relationship with him.

Iantha Richardson plays Faith Mitchell, the team’s technical and forensic expert who finds key evidence. She was also Trent's partner before he went away. Jake McLaughlin appears as Michael Ormewood, a reliable partner in field operations; although he started off on the wrong foot, he has developed as a human and detective. Sonja Sohn is Amanda, the team's supervisor who manages resources and decisions on investigations. These five actors make up the backbone of the show’s cases and character moments.

Bringing back the established leads keeps the series steady and familiar for returning viewers, while adding a strong legal character shifts some focus toward how cases are won in court.

That balance of fieldwork, lab work, and courtroom drama helps the season explore different kinds of tension and character growth without changing the show’s basic method.
