Azula watched him work to save the people. Now it was just to get and keep the boy's attention.
"Tell me..." she called, propelling herself down toward the ground easily, few firebenders but she and her father could do something like this. Or could have done in her fathers case. "How does it feel being alone, no one else that can help you. How do you hope to fight me when you couldn't before?"
She kept back from the waterbending. Waterbending had been her downfall before. But Katara was not here and powerful as the Avatar had been by the end he was not powerful now, here he was still afraid of the power of the Fire Princess.
"Its lucky for you Avatar I have no reason to care, My Kingdom is not here, your friends aren't here. And you fear me. So we can just continue as before, me doing precicely what I wish and you trying to clean it up and save everyone. Call this little exercise a lesson in humility, in knowing your place"
