Jensen Ackles is back for Tracker season 4, and his first episode starts filming in a matter of days. Justin Hartley laid out the return at a Televerse panel in Los Angeles, setting up an immediate continuation of the brothers’ storyline before the season opens on Sunday, October 4 at 9:30 p.m. on CBS.
Hartley Sets the Return
Hartley said, “We left him in a place where he was doing something for Colter — keeping a secret from him, but for Colter's own good,” and then added, “He took one for the team. Quid pro quo: 'I'll do this for you... just keep him out of it. He doesn't need to know any of this. It's to protect him.'” That puts Russell’s re-entry on a specific footing: he is not simply back in the story, he is back because the secrecy he chose has now boomeranged.
“When we find him this season... he needs a favor from Colter and from his skill set. So the two brothers work together to solve this problem that Russell's found himself in — and one of his friends, too,” Hartley said. The setup points to a practical division of labor, with Colter bringing the kind of help Russell needs and Russell carrying the consequences of the choice he made before the season turned over.
Season 3 Left Loose Ends
Season 3 ended with Colter and Russell learning what happened to their father, Ashton, and that thread widened fast. Ashton was tied to a covert, DARPA-funded government program experimenting on gifted children, while Colter rescued Chrono Stasis test subjects Danny and Lola. Russell also received troubling new information about something Ashton had done to Colter as a child, which turns the family file into a personal one instead of a purely historical one.
Russell then phoned Reenie and asked her to keep Colter off his trail, then said he would fill her in on where he was headed and why as soon as he could. That leaves his position in Season 4 clear enough for the audience to track: he is arriving with unfinished business, a favor to ask, and a problem that has moved beyond private family history.
October 4 on CBS
Tracker season 4 premieres Sunday, October 4 at 9:30 p.m. on CBS and streams the next day on Paramount+. The timing makes Ackles’ return more than a casting note; it arrives as the show resets the family arc around what Russell knows, what Colter does not, and what the brothers now have to solve together.
That is the useful read for viewers: Season 4 does not need to rebuild the premise from scratch. It is picking up a live wire from the Season 3 finale, and the first episode is set to start filming almost immediately, which should push the Russell-Colter thread back to the center of the season quickly.
