Katara smiled. "Good, glad you got that. you don't have to get so exasperated Jamie. I'll always listen to you, you know. We may not agree on everything, but you're my friend, and you give good advice. I know when someone is looking out for me. Thank you."

She smiled and patted his shoulder. "I'll try to go easy when I can, okay? that's about the most I can promise anyone."

Katara listened to this part with rapt attention. "You know, I actually understand the regeneration thing: Aang is the Avatar, and they go through something similar called reincarnation. Basically, when the Avatar dies, his spirit goes into someone in the next part of the cycle of another nation. Even though that person is obviously different, they not only have some of the memories of previous Avatars, they also can tap into them as separate people and gain wisdom from their years of wisdom."
