Tracker Season 4 Cast Shake-Up: 4 Characters Who May Not Return to the CBS Show

Robin Weigert was part of the CBS series Tracker only in Season 1. She played Teddi Bruin, one of the handlers for the show's main character, Colter Shaw. Weigert exited the cast ahead of Season 2 and has not returned since. So, it seems unlikely that she will come back in Season 4 after sitting out the last two installments.

Eric Graise's return for Tracker Season 4 also seems out of the cards. He portrayed hacker and tech expert Bobby Exley in the first two installments before departing the CBS drama ahead of Season 3. After his exit, Randy (Chris Lee), who is Bobby's cousin, took over the tech-support role. Notably, showrunner Elwood Reid stressed that Lee did not “replace” Graise, explaining that it is about “where I get the most creative juice.” In a 2025 interview with TVLine, Reid explained, “Having Chris Lee in the same space that Fiona Rene is in just gets you [more]. The stuff we've seen so far is so much fun. It has made a huge difference.”

For Abby McEnany, it's pretty much the same story as Eric Graise. She starred as Velma Bruin, one of Colter Shaw's business handlers, in Seasons 1 and 2 before leaving the drama ahead of Season 3. Given that she hasn't appeared since, a Season 4 return seems like a long shot.

Sofia Pernas has appeared in all three seasons of Tracker as rival rewardist and recurring character Billie Matalon. Then you might be wondering why we think she won't return in Season 4. Well, fans may remember that she is Colter Shaw's former romantic partner, and now the CBS drama is introducing another love interest. EP Elwood Reid told Us Weekly, “Putting the Billie thing aside for a second, what would happen if there was someone who challenged him emotionally in a way where maybe his job comes into cross purposes with that? That's the thing we're toying with. We've shot two scenes with this person, so [we're] just seeing if it'll work.” Meanwhile, speaking with Deadline, Justin Hartley noted, “I can tell you who I would love to bring back. I would love, of course, to bring Sofia back.” So, there might be a chance that Pernas pops up now and then in future episodes, as she has been doing so far.
