Ok, well, i don't think Zuko's mom killed anybody. I think Ozai killed his father. To get his palce. And?? then maybe Zuko's mom like ran away because she was so mad.
Or another theory. Ozai really was goign to kill zuko and (i'm not copying, i'm agreeing) Zuko's mommmy put herself up instead.
But Azula with the knife...also leaves me with speculations.
But in the beginning of the eppie, i thought that all those guys in kiddie form was cute. I was like squealing when i saw teeny Tylee and Mini Mai.
