His worried parents attempt to rescue him from a life-time of involuntary service, but Trace realizes something important about himself at the 13-week boot camp: the training he receives is valuable. It changes him.
Trace clearly benefits from the skills he learns in the Zone Troopers, but that fact doesn’t change the truth that the organization – no matter its revered “Hall of Heroes” – takes its marching orders from a corrupt and cruel state. Trace is able to separate the commendable ethos of the Zone Troopers ("proficiency, pride and prowess") from the unfit command structure that deploys it.
You get the feeling the creators of the series had some interesting history in mind there, and I love when Otherworld heads off on these unexplored weird tangents.
