An overlooked villain from Tracker season 1 would be the best returning character for the show’s sophomore season. Justin Hartley’s Colter Shaw, a self-proclaimed “rewardist” living on the open road and solving missing person cases, has many adversaries in Tracker season 1. While the show’s first antagonist character, Jensen Ackles’ Russell Shaw, turns out to be a good guy, most of the people Colter comes up against aren’t.
