It's funny how we always talk about Satoru letting Suguru get away so many times and being unable to kill him and that's why Suguru was able to do evil cult leader things for 10 years because the ONLY person strong enough to face him just wouldn't and couldn't, but we never bring up how Suguru never came after Satoru.

Is Jason struggling hard trying to deal with envy that Tim has taken his family, his place in the court, his dragon? Of course, but at the end of the day Tim never owed Jason’s memory any respect or loyalty. But the egg he stayed up late whispering his hopes and notions of friendship and happiness and protection, patient and gentle for years, despite everyone telling him it was a lost cause. His egg –now a dragon– has forsaken the only person to dedicate themself wholeheartedly to its safekeeping. So Jason might eventually get to a point of understanding and tolerance with Tim but the little dragon must have felt him off in the distance and given up on him. It is the only way the pieces fit together. How can Jason accept that? He never faltered in his belief in his egg but as soon as he seemed weak it discarded him for someone easier to love.
