AceShowbiz - Tracker is gearing up for an exciting conclusion to its third season with the return of Jensen Ackles. After appearing in the first two episodes as Russell, the brother of Colter Shaw, he is set to rejoin the cast for the final two episodes, including the season finale on Sunday, May 24.

Fans now know that Ackles will not only be featured in the last episode but also in the penultimate installment airing Sunday, May 17. Episode 21, titled "Chrono Stasis," centers on a reunion between Colter and Russell as they embark on a personal mission to uncover secrets related to their father’s mysterious past. A newly released photo highlights this pivotal episode.

The season finale, Episode 22, titled "The Best Ones," follows the brothers as they investigate a victim connected to a suspicious research project, continuing the show's deepening intrigue.

The April 26 episode of Tracker (Season 3, Episode 18) advanced the storyline involving the brothers’ father without revealing all the answers. Colter’s investigation led him to Buck Avery, played by Michael O’Neill, who shared information about a secretive operation called the Chrono Stasis Institute. This defunct research facility was allegedly connected to government contractors and abruptly shut down after a mysterious accident. The project reportedly received support from DARPA before it ended under unclear circumstances.

Buck directed Colter to Dr. Serena Jukic, a key figure who might hold the truth about the accident. However, Jukic vanished after mentioning the incident. The episode concluded by setting up the season’s climax and Jensen Ackles' upcoming return. Colter left a voicemail for Russell, explaining their father’s involvement in a potential government cover-up and urging him to assist in finding Dr. Jukic, who is portrayed by Jeri Ryan from Star Trek: Picard.

Before Ackles' return, viewers will see Sofia Pernas, wife of co-star Justin Hartley in real life, reappear in Episode 20 airing Sunday, May 10. In this episode, Colter’s investigation into a woman who disappeared from a rehab facility leads to an unexpected encounter with Billie, revealing a possible connection between their cases.

Additional photos featuring Jensen Ackles' return to Tracker have been released, showcasing moments from the upcoming episodes. Fans are encouraged to share their excitement about Russell’s return as the season approaches its thrilling conclusion.
