Will Trent season 4 is back with its core team solving crimes and confronting their own complex lives. The new season picks up after a dramatic finale that left characters fighting for their lives and facing huge personal choices. The show’s success comes from this mix of exciting cases and the personal struggles of its characters, brought to life by a talented group of actors.
The cast list has some key changes this year. A fan-favorite detective has been promoted to a main star, while another familiar face from last season will not be returning. This mix of returning favorites and new status for supporting characters keeps the series feeling fresh.
The Core Investigative Team
The heart of the show remains the partnership and friendship between Will Trent and Faith Mitchell. Ramón Rodríguez is back as Will Trent, the brilliant but emotionally guarded GBI special agent. Rodríguez is also stepping behind the camera, directing multiple episodes of the new season, including the premiere. His character is trying to build a stable life after a difficult childhood, a journey that continues to define him.
By his side is Iantha Richardson as Faith Mitchell, Will’s partner and moral compass at the GBI. Initially skeptical of Will, Faith has become one of his most trusted allies. Their strong working relationship is a key part of the series, and Richardson will continue to play this vital role in season 4.
Leading the GBI is Sonja Sohn as Amanda Wagner, Will’s boss and a mother figure to him. The season 3 finale left Amanda in critical condition after she was shot. Despite this cliffhanger, promotional material confirms Sohn’s return for the new season, leaving fans to wonder about her character’s recovery.
The Atlanta Police Department and Personal Connections
The story often overlaps with the Atlanta Police Department, where several key characters work. Erika Christensen returns as Angie Polaski, an APD detective and Will’s childhood friend from the foster system. Their on-again, off-again relationship is a central story, and Angie is now dealing with a major life change after deciding to keep her baby.
Angie’s partner at the APD is Jake McLaughlin as Michael Ormewood. The character also collapsed at the end of last season due to a brain tumor. McLaughlin is confirmed to be back, and his character’s health will likely be a major focus.
A significant promotion this season is for Kevin Daniels. After appearing in a recurring role for three seasons, Daniels has been upped to a series regular. He plays Detective Franklin Wilks, a calming presence at the APD and Angie’s friend and AA sponsor. This means viewers will see much more of his character.
Another important return is Yul Vazquez as Sheriff Caleb Roussard. Introduced late in season 3, Caleb was revealed to be Will’s biological father. His stubborn, small-town ways created instant tension with Will. Vazquez is confirmed to be back, exploring this complicated new family dynamic.
Beloved Supporting Characters and a Key Departure
No list of the Will Trent cast is complete without the show’s scene-stealing canine. Bluebell is back as Betty, Will’s loyal chihuahua. Betty provides Will with constant companionship and has become a fan favorite for her expressive eyes and funny moments.
Other supporting players making a return include Cora Lu Tran as Nico, the non-binary pet-sitter who looks after Betty and has become part of Will’s extended family. With Angie’s pregnancy storyline, Scott Foley is also expected to return as Dr. Seth McDale, the father of her child.
However, one character from season 3 will not be back. Gina Rodriguez, who played Assistant District Attorney Marion Alba, has exited the series. Marion was a love interest for Will, but their romance did not last. Co-showrunner Liz Heldens confirmed the character would not return for season 4.
Where to Watch the New Season
The two-part season 4 premiere aired on Tuesday, January 6, 2026, on ABC. For viewers who prefer to stream, new episodes are available to watch every Wednesday on Hulu and on Hulu via Disney+ for bundle subscribers. The season is scheduled to have a total of 18 episodes.
Author and executive producer Karin Slaughter said, “There were so many cliffhangers in that last episode of the season, and they’re just picking up where they left off and doing amazing things”.
The new season dives straight into the aftermath of the biological terrorist attack and the personal crises of its characters. With its cast of returning favorites and a promoted star in Kevin Daniels, the team is ready for its latest set of high-stakes cases.
