For endlessflame55, who requested something about Zuko and Iroh's relationship.
Tally
Zuko can count the things he knows about fathers on one hand, unwritten laws that govern interaction.
They are to be respected. They are to be obeyed. They are to be feared.
He knows that they should also be made proud, but he has never managed that. The last, that they should be loved by their sons and love their sons in return, is something he tries not to think about at all.
Zuko has never tried to count the things that he knows about uncles.
They command only when necessary. They push for more, but with faith instead of intimidation. They make mistakes. They placate. They protect.
They care.
Once he ignored the tally because he thought it unimportant. He was right. But years have taught him that the rules of uncles do not matter because uncles do not try to govern their nephews at all.
