Literally anything couldve changed the trajectory of Tma, but I think the thing that fucks me up the most, is the fact that I’d argue a lot of the reason Jon even ends up in that precarious place between avatar and human (”how much of you is left”) is because after all that time nobody, not even martin treated him like a human. Jon tried his damnedest to help, and persevere, and he did what humans do to survive, make bad choices. And everyone invalidates that. His needs, like statements, are viewed of that like a dog needing to be taken on a walk. His acknowledgments on his capabilities are never about him, and only the powers, the things he can take and steal and do, and martin pushes him to use the powers and yet is so shocked when Jon is more horrified with himself than when he started.
