Jensen Ackles' role in Tracker season 2 is made even more exciting by the promise that another season 1 character will be on hand. The Colter Shaw actor has promised some characters will return, and apparently Ackles' Russell Shaw will be among them. The star's chances of appearing in Tracker season 2 seemed slimmer after Ackles has been cast to star in a new show on Prime Video called Countdown. However, it's since been confirmed that despite that, he will be taking on a recurring role in season 2.

In Tracker season 1, Russell was vital to the story. He texted Colter throughout the show's freshman season before eventually appearing in the penultimate episode to plea for the reward-seeker's help. Russell needed to appear because it was believed that he had killed their father, Ashton Shaw. Russell revealed in season 1 that he didn't kill their father and that there was someone else in the woods with them that night.
