Anon asked: How would Zuko deal with feelings jealous over Azula? Especially if he's still in denial of the true nature of his feelings.
He would try to rationalize his feelings, and decide that his jealousy is actually something else.
He is not jealous that some guy was checking Azula out, he is just bitter that no one would ever think he is attractive after his father disfigured him.
He is not jealous that people are praising Azula for her fire bending, he's just frustrated that his sister gets so much attention while he is always alone and looked down on.
He is not jealous that their dad is probably the one person Azula loves more than herself, he is just angry that the only family members he still has are so close to each other, yet mistreat him.
He is not jealous that Azula actually seemed a little upset when she heard that Lu Ten died, yet laughed when Ozai burned his face. He is just confused and frustrated by how cold and cruel she can be - hell, she even hoped to see dad on the throne five minutes after Lu Ten died! Of course he's not jealous of such an awful person!
He is not jealous that Azula is always with Mai and Ty Lee, he is just bitter that he doesn't have any friends and these two probably only hang out with him because he is Azula's brother.
He is not jealous that Azula was clearly bothered by how close he was to their mother, he simply misses Ursa and wants to know what the hell happened to her. He doesn't care that Azula wanted her affection, but not his.
He is not jealous that Azula was attracted to some random guy, he is just irritated that he has to third wheel her, especially for someone who is obviously beneath her.
He is not jealous. He doesn't care. He doesn't want her. He is not upset that she is never going to look at him the way he looks at her.
