Although there are a lot of people who think that in Avatar there will be a Zutara I think??there will be a Kataang.I have enough proof to say so. In the episode "Return to Omashu"??at the end Ty lee says "It will be nice to see zuko agian, won't it Mai?" The second Ty lee said that Mai turned her head so her friends wouldn't see her blush.Then on "Zuko Alone " Zuko was having a memory of the past and in it he was walking with his mother in a hallway. While they were walking Mai turned her head?? so Zuko wouldn't see her blush and smile (which in this case Mai rarely smiles).To bad for Mai,Azula saw. Anyone could tell that Mai will go with Zuko.It is going to be an Zai relationship.Aang is going to get Katara, that is if he doesn't let her go.I'm sure he will find another way to master the avatar state.
