Well, i hope to hear lots of 评论 from 你 guys!
Here is what I think will happen,
Zuko's father, Ozai, will tell Zuko about his mother. Then, he will get mad at Azula, because, Azula knows something, 或者 knew something but kept it from Zuko. But, then Aang puts his hand on Zuko's shoulder and says, We should go.
So, they leave off in 搜索 of Zuko's mother.
What do 你 think will happen?
