Theory, by Nuptaa
You know how Zuko is related to Avatar Roku? So that mean that Azula is too. Did you notice how they never really mentioned anything about Azula. I think that Iroh and all the other people are probally expecting that Zuko is the one to be good or whatever it is. But I think that Azula is the one who's going to turn good as some weird twist. In the avatar magizine it was talking about Aang learning firebending, and it said something like, 'Could Zuko switch sides? Could Azula swich side, Could Iroh teach him, or could it be a new character?' So it did propose that Azula could switch sides...
