Season three put Tyler on a much better path than he'd been on at the beginning of the series. After being stopped from shooting up the school in season two, Clay and the rest of the group do everything they can this season to keep an eye on Tyler and help him feel accepted and OK. He ends this season by not just admitting to the school that he'd been sexually assaulted and turning Monty in for it, but also by having his photographs displayed in Monet's as an art exhibit. He says it's all the people who have helped him. I can only hope that things continue looking up for this troubled kid.
