Azula knew she wasn't trusted. Of course she did, Zuzu wasn't stupid, he had to know she'd betray him soon as look at him. But here, in this place she needed her brother. For now at least and for that she would take his distrust and his jibes about it being that weak man's favourite kind of tea. Zuko would always jibe at her, always try to prod her into attacking him or something. One way or the other. He was wary. And he was probably still very mad at her for the whole Agni Kai thing. Well if he hadn't brought his pet water peasent to the fight then maybe he wouldn't have to be so mad at her. "Well Uncle did know his tea I suppose so his word must be trusted on it. I suppose he needed something to fill his head with after he was such a failure in the greater war." she said, she hadn't said it to be snide it was just a fact. He had been a failure.
Azula was so used to lies, but it was hard to lie to someone who knew her as well as her brother did. This sibling bond she'd heard so much about simply didn't with her. The doctors at his blasted facility had said she was mad. Had said she didn't form relationships like other people did. Normal people. But who were they to judge her. "You left, I left, we both returned, we fought, you cheated, you won, you locked me away. When were we ever to have time for something so simple as tea." she told him matter of factly. "They would give me some to drink sometimes. One or two of your guards, not loyal to me or anything but just...I believe they...ugh...pitied me. I would have burned them alive if they'd ever let their guard down. Pity is a weakness Zuzu, remember that."
He wouldn't wish this world on anyone, or her company. It could easily have been both with her brother.
She watched him busy himself with making the tea while she thought about what he'd said. It was a fair point. What did normal siblings do? "Well I expect they talk sometimes, go to parties together which we did once, do you remember? When we discovered why Mai was so angry and annoying all the time and why Ty Lee was so ridiculous. And you..." she trailed off, fighting the smirk that came to her so easily at the memory of his ridiculous little outburst back them. "I think we're supposed to help each other and be there for each other. Things like that, should we try it?" she queried, sipping the tea as she wondered could they ever be normal siblings. Or if she even wanted to be.
