30-year-old Zuko gets randomly flung back in time to his 16-year-old self. For a couple of hours at a time. At the most random times imaginable. Imagine the potential.
Zuko assumes that it's a dream or a vision, but definitely not real. He tries not to freak everybody out too badly, but he's also fully enjoying himself and seeing all of his friends as their young selves.
ZUKO, as he and Aang circle each other at the South Pole: I've spent years preparing for this encounter. Training, meditating. You're just a [Spirit Shwoop Sound] ... baby Aang!
AANG, confused: Well, more like preteen Aang. How do you know my name?
ZUKO, looking around: Wait, where are we?
SOKKA: Don't answer him! He's trying to get information out of you. You can't give away our location!
KATARA: Sokka, he's standing in the middle of our village. I think he knows.
ZUKO: We're here? This is so weird. I was just here for the Annual Penguin Race.
AANG: THERE'S AN ANNUAL PENGUIN RACE?!
ZUKO: Well, yeah, it was your idea... you gave a whole speech about cross-cultural cooperation and friendship, but I know you just wanted to go penguin sledding with a bunch of people...
SOKKA: Stop giving him more information! He already knows about the penguins!
Everybody else is confused, bewildered and even befuddled except for Iroh, who assumes that it's Spirit Shenanigans™️ and just fully accepts that his nephew likes tea and hugs and Pai Sho sometimes while being his usual shouty surly traumaball self at others.
ZUKO, stepping into the cabin: Hi, Uncle. I brought you some ginseng. How about a game of Pai Sho?
IROH, tearing up a little: I would love that, my nephew.
ZUKO: I wish we could do this more often, but you live so far away...
IROH, mentally calculating that he lives exactly three doors away from Zuko, and nodding sagely: The rat-viper may never climb the mountain that a hog-monkey can, but the monkey does not know what lies underneath it.
ZUKO, sighing sadly: I know, Uncle. I do appreciate my position in life, even if it has disadvantages.
IROH: Hmm. Your move, nephew.
The crew of Zuko's ship is terrified by the fact that whenever it happens, Zuko is somehow even more hyper-competent, seems to be weirdly calm about everything, and most unnervingly of all, he's polite.
SOLDIER: Here is a report on the best teahouses within three days travel of our current location, Sir. And, uh, Commander Zhao sent a messenger hawk.
ZUKO: Excellent. Thank you very much, Sergeant. I think we can ignore whatever Zhao has to say. In reply, I want you to send him a list of the most famous officers in Fire Nation history, and point out that none of them had sideburns. I want to see if he shaves them.
SOLDIER, sweating nervously: O-of course, Sir.
As a matter of fact, the whole fic could just be Zuko trolling Zhao. It would be glorious.
