The western air temple was about zuko switching sides and joining aang to teach him firebending but katarra,sokka,toph,and aang dont accept him at first but then at the end aang is all like i think あなた are supposed to be my firebending teacher.
Well yeah what the other person said! It's about the アバター gang going to the westurn air temple after the invasion plan failed. So Zuko follows them and asks to 登録する there group. They say yes but Katara isn't sure cos she knows he has had a hard time doing the right thing. But if that wasn't any help then あなた can just go to the アバター portal and then あなた can watch episodes there!
