Well, i hope to hear lots of comments from you 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, or 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 procurar of Zuko's mother.
What do you think will happen?
