Although Billy wants to live his life outside the rules, by remaining in Bendarat and forging relationships with Old Bill, Caitlin, and even Irene Thompson, he remains tethered to the world of the rule-makers. In other words, he values relationships with others more than his absolute freedom. Though poor in worldly possessions, Billy is rich in what matters: love, friendship, and luck. By helping Billy out in this way, Old Bill redeems the house he’s left empty for too long. He also reclaims the education and training (as a lawyer) that he abandoned after his personal traumas.
