Zuko was your childhood best friend, whom you had a crush on, but when he's father banished him from the kingdom. You never seen him again. And now 2 years later, you are travelling with Aang, Sokk and Katara, so basically the Gaang. You are a really trusted friend. You are a firebender, but they trust you since you saved them many times. You guys were on Appa flying across the water when a fireball came at you guys. Aang dodged it with controlling the air. You guys looked down to see Zuko.
