[@McHaggis]I was thinking about that as well. I'm not sure how long Nilak has been in Ba Sing Se but maybe they could have met briefly if Amaya would also treat people in the upper ring. I also have some idea's on how Dao could end up interacting with some of the other characters. He could receive orders to go undercover in the Ba Sing Se university to find out where the loyalty of a certain descendant of a firenation citizen lies ;)
