Kamichi said nothing as he saw the man go away, and went along with him to close the doors and be sure he was going out without further incidents. It would create an scape route for Azula, but he spected her to be intelligent enough as to realize that a present with him was far better than a future without him, her strength, her allies or her throne.
Kamichi was now curious and alerted, for the government of the Fire Nation had sent out a militar policeman and not a doctor to supervice him. What did this mean, other that nobody understood that the poor girl was sick? Were his superiors not yet sure that he could do this, and sent that soldier to supervice and (if need be) stop him?
After the silent stroll, he got back to the inner doors of the institution that looked more like a temple than a hospital, and breathed all the smoke out of his lungs.
He always built up smoke when thinking, but he was improving in this. When he felt ready, he went back to the garden where he left Azula, and looked around for her.
