Not Ready for the Responsibility

Your an air nomad, just like Aang, and you both grew up as best friends.

No one liked hanging out with you though, since you had a weird ability.

You weren't the avatar, but you could bend all the elements.

And ever since Aang was dubbed as the next avatar, you and him would spend time together, since none of the other kids your age wanted anything to do with either of you.

It hurt, but at least you had each other.
