There is no individual thread for this specific topic, its just the idea that is the same.
I have always thought that Azula's plotline would end with something backfiring on her. From what I have seen from the Boiling Rock this seems to starting after the betrayal of Ty Lee and Mai which is the backfiring of her forcing her will upon others. It would seem that the next logical step in her plot line would be for her firebending power to backfire on her which could involve her losing some of her abilities. Another possibility is that some problems with her mother Ursa could come back to haunt her first.
