The best part is Aang wouldnât even teach him airbending in the beginning. First itâd be brewing the perfect cup of teach and blowing on it in juuuust the right way that it cools down âBut not too cold, or youâll ruin it!â
Brushing Appa of course. Zuko would be pretty decent at that, but would come back to Aang absolutely covered in slobber and bison hair. âAwww! He likes you! <3âł
Then itâd be calming meditation and slowing Zukoâs breathing (âBut I am calm!â), tracking an elusive and nigh legendary animal so they can ride it, teaching patience by baking the perfect cake âYou just slapped the frosting on! It looks awful! *airbends it into the horizon* âAgain!â
When Zuko finally gets it right, he almost smiles at Aang saying: âExcellent work, my student.â Then to Zukoâs consternation and horror Aang flings it at the head of the Fire Nation Governor during a political function. âAnd now we run!â
Pranks would be absolutely the thing that would bluescreen Zuko. Hereâs an airbending master, over a century old, witnessed the genocide of his people, and heâs juggling, doing dances and tricks with Momo for the village kids, and plaguing the local aristocrats and military officers with flying cakes and whoopie cushions.
âHow am I supposed to beat the Firelord with whoopie cushions?!â
And then, perfectly serious for the first time since Zuko had met him: âYou donât. The Avatar is about restoring balance. This training isnât so you can fight the Firelord - itâs so you can stop a war.â
It takes a long time for Zuko to understand this. But the weird thing is: the townsfolk actually like Aang. Sure the aristocrats and crooked merchants and the officers donât, but even the common Fire Nation infantry hide their chuckles with a cough when they see their commanderâs fancy armor get covered in honey and feathers by âCrazy Aang,â again.
And Zuko realizes, at that moment, that heâs been having fun.
So, waking early, with no prompting from Aang, Zuko feeds Momo, brushes Appa, washes off the slobber, brews Aang his morning tea -perfectly cooled- and then proceeds to make a new, beautiful cake with no explanation.
âThat looks wonderful, my student. Your best yet! Who were you planning to-â
Then Zuko smashes it in Aangâs face.
Itâs the first time since coming out of the ice that Avatar Zuko laughs.
