Ohhhh. I love these two ideas. Out of the two, though, I think I like the second one -- mostly because it deviates the most from canon. I especially like the fact that Zuko, older now, reconizes his father for what he is and is more willing to be talked into the Gaang that way. *sigh* I love myself some Zuko-Toph platonic friendship as well. What are the chances of you writing either one of these plots? *bounces*
