A 'Canon Divergence', I believe it's called. So, basically, this story picks up when Zuko and Katara are flying back to camp during the 'southern raiders' episode; book 3, episode 14. This fic is an alternate ending, the ending we were robbed of, for Avatar: The Last Airbender. Zuko and Katara, much to Katara's original dismay, are a perfect duo. They balance each other, yin and yang like. They serve as the perfect reminder to each other to not look back; they're not going that way.
