With the exit of multiple series regulars ahead of Season 3, Tracker is set for a major refresh. Here’s everything we know about who’s staying, who’s going, and exciting new cast additions—including Sofia Pernas, Jensen Ackles, and more.
Who Is Not Returning?
-
Abby McEnany (Velma Bruin) and Eric Graise (Bobby Exley) are no longer part of the Season 3 main cast. These departures mark the second major shake-up following Robin Weigert’s exit at the end of Season 1.
Returning Cast

Justin Hartley continues as Colter Shaw, the only constant in the series’ upheaval.

Fiona Rene remains as Reenie Greene, Colter’s trusted lawyer.
New & Recurring Faces Joining Season 3
Jensen Ackles as Russell Shaw
-
Ackles returns in a recurring capacity as Russell, Colter’s estranged brother. His involvement was confirmed via an Instagram video on set with Hartley. Ackles and Hartley share nearly two decades of friendship, and Ackles described their dynamic as “natural and fun.”
Melissa Roxburgh as Dory Shaw
-
Colter’s sister Dory, a physics professor, is expected to reappear in Season 3, although her availability depends on scheduling.
Chris Lee as Randy
-
Introduced in Season 2, Randy (Bobby’s cousin) may step into a larger role, possibly taking over tech duties. This change could help evolve Reenie’s story and broaden the “team” dynamic.
Family Cast Returns
-
Wendy Crewson (Mary Dove Shaw, the mother) and Lee Tergesen (Ashton Shaw, father; via flashbacks) are expected to return as the show dives deeper into family history.
Sofia Pernas as Billie Matalon
-
Actress Sofia Pernas will guest star as Billie Matalon, a connection that’s likely to introduce a new dynamic to Colter’s cases and relationships.
What This Means for Tracker Season 3
-
With the core tech team of Bobby and Velma gone, Reenie and Randy’s roles may expand alongside Colter’s evolving family arc.
-
The season is expected to address major plotlines involving the mysterious death of Colter’s father, Colter being framed, and possible government conspiracies tied to his mother.
-
Fans can expect emotional reunions, deeper character work from Hartley, and fresh interpersonal dynamics across the cast.
Season 3 Details
-
Premiere: Sunday, October 19, 2025 at 8:00 p.m. ET on CBS (and streaming early on Paramount+).
-
Episodes: Season 3 will feature 13 episodes (down from previous seasons), focusing more tightly on narrative arcs.
Though Tracker loses familiar faces in Season 3, it gains new layers through Colter’s family and personal journey. With characters like Russell Shaw (Jensen Ackles) and Billie (Sofia Pernas) joining the fold, and Randy stepping up behind the tech screen, the show is poised for reinvention. And though only Justin and Fiona remain from the original cast, their evolving roles promise new emotional depth—and renewed direction for the future.
