Well, i hope to hear lots of commenti from te 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, o 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 cerca of Zuko's mother.
What do te think will happen?
