"I don't know. But I have hope. Those who were born with bending, it's a part of them, even more than those that have been given bending. It's not the whole of who they are, but it is a piece of them and as much as I know it doesn't define them, that it doesn't define you, I do think you should be able to feel whole. So I hope."
