Zuko:
[to an unconscious Aang] I finally have you. But I can't get you home because of this blizzard. There's always something. Not that you would understand. You're like my sister. Everything always came easy to her. She's a firebending prodigy and everyone adores her. My father says she was born lucky. He says I was lucky to be born. I don't need luck, though. I don't want it. I've always had to struggle and fight, and that's made me strong. It's made me who I am.
