Well, i hope to hear lots of टिप्पणियाँ from आप 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, या 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 खोजिए of Zuko's mother.
What do आप think will happen?
