Who’s that bold guy on the right? I used to think Aang was councelmen representative for the airnomads. But he seem not to be a part of a council at all!
Having all powers he represents the whole world. And with his popularity it is only fair to have him out of council. On the other side, he was the last airbender and the last airnomad and that guy is a newbie, how can he represent the vanished nation instead of the only last true airnomad?
Aang probably didn’t want to be on the council because he would hold so much power as the Avatar and, knowing Aang, he didn’t want all that power. As for that guy…probably an Air Acolyte.
