zuko alone is one of the best written episodes of the entire show. It's probably the first time where the public starts rooting for the "villain" and the kid not forgiving him makes the episode better bc for the first time zuko feels ashamed of being part of the fire nation
Along the way somebody was gracious enough to take a chance on you because you had the right attitude even if you didn't have the skills to match. It's only right you extend the same grace to someone else.
