Jensen Ackles is back on Tracker. The Supernatural star returned as Russell Shaw in season 4, episode 5, “Need to Know,” which aired on CBS on Sunday, November 1, 2026 — and the reunion of the Shaw brothers was the episode fans had been waiting for.
Ackles plays Russell, the older brother of Justin Hartley’s Colter Shaw. In the episode, a military contractor’s wife and daughter are kidnapped, and Colter discovers that Russell is already investigating a related lead. The brothers team up to uncover a cover-up tied to a file connected to their father — and to something that happened to Colter as a child.
The episode ended on a quiet note, with the brothers heading out for beers after a case that left plenty unresolved. It was the kind of low-key finish that made the reunion feel earned rather than rushed.
Why the return matters for Tracker
Russell Shaw is not a one-off guest spot. He is central to the show’s biggest mystery: what really happened to the Shaw brothers’ father, and what Colter does not yet know about his own past. Ackles first appeared as Russell in season 2, and his appearances have become the moments when the show’s family story moves forward.
“Need to Know” leaned into that. Instead of rehashing old arguments between the brothers, the episode had them solving a case together, with Russell still holding back a dangerous secret about the assignment he was on. That tension — two brothers working side by side while one of them knows more than he is saying — is what the episode was built around.
The return also landed well with viewers. According to FlixPatrol’s daily rankings, Tracker reached No. 3 on Paramount+’s U.S. television chart on November 3, 2026, trailing only South Park and Marshals and sitting ahead of established favourites including Tulsa King, NCIS and Tom Hardy’s MobLand, which fell to No. 7. A daily chart position cannot prove which actor drove the surge, but the timing — two days after Ackles’ return episode — is hard to ignore. FandomWire’s report on Tracker’s chart climb covers the rankings in full.
Will Jensen Ackles be back on Tracker?
Yes. Justin Hartley has said Ackles will return for more episodes, with most of his appearances expected at the start of 2027. Speaking to TV Insider, Hartley said: “He’s in at least one [episode], and we’ll have him back when we can.”
That fits the pattern of the role. Ackles’ Russell appears in short runs that push the Shaw family mystery forward, rather than as a full-time regular — which makes each return an event for the show’s fans.
What else Jensen Ackles has coming up
Tracker is not Ackles’ only project. He is set to star in Rules of Prey, an upcoming MGM+ series in which he plays Lucas Davenport, a detective who returns to the Minneapolis Police Department to investigate a series of murders. The first season will have eight episodes, and three new cast members were recently added — but there is no release date yet. MovieWeb’s look at his Tracker return also covers what Rules of Prey could mean for him.
Ackles is also back as Soldier Boy in the final season of The Boys on Prime Video, a role that has kept him in front of a very different audience from his Supernatural days. Between Tracker, The Boys and Rules of Prey, he is one of the busiest actors on television right now.
How to watch Tracker
Tracker airs on Sundays on CBS, with episodes available on Paramount+ live for eligible Premium subscribers and on demand the following day. Season 4, episode 5, “Need to Know,” is available to stream now.
