Can I ask for one where Lu Ten lived in Ba Sing Se, but Iroh didn't, and Lu Ten ended up as Fire Lord. How would Ozai have handled that? Would Azula and Zuko have turned out any different?

From the Vampatar AU-- Zuko finding Sokka can turn into a wolf

What if Pakku had run into Zuko during the invasion of the Northern Water Tribe? How would their interaction play out? ( I have this mental image of Pakku jut scolding Zuko for trying to sneak in:)
