We are who we are

Whether we fight it or accept it, we are who we are. But who are we exactly? What do we want? What must we do? What do we sacrifice? What do we gain? The answers will be in the roads we take between love and duty. That's what the Avatar, Katara, Sokka, Chenlian, Zuko, their friends, and their enemies will learn during their journey.
