-saves adoptee's thread-
If the title picture had her telling how she learned waterbending, earthbending, and firebending already, it could have flashbacks to her learning from Katara, Toph, and/or Zuko if any of them were around when she learned those elements. the Gaang probably would have no problem with teaching the next avatar since it was their closest friend incarnated. I can totally envision Toph doing that, Katara sorta, and Zuko not really. But it'd be pretty neat. Their age might get to them, but it didn't seem to get to Bumi, Roku, or Sozin.
