A/N: Okay, no excuses here. The thing is that I was away on holiday around the end of Zutara Week, and then simply didn't have the inspiration to write… But I'll finish all the prompts, I promise :)

Day Four: Gravity

Iroh is familiar with times like this – when his people are preparing for battle, sharpening swords and hardening hearts, everybody so tense they are ready to snap, because the next few days, the next few hours, what they have until Sozin's Comet arrives, will decide about life and death, and usually he is just as tense as the others around him, if not even more so, because the weight on his shoulders are always mightier, has always been, but now – now he can barely keep the smile off his face.

Because he is almost completely sure that his nephew is in love.

Zuko has always been one to try to please others. It is the way he was raised, how Ozai wanted him to be, for which Iroh can't help but condemn his brother. And, alongside with this urge of his, Zuko has never been very smooth when ladies were concerned – and what he is doing right now around the pretty waterbender girl is rather amusing and bordering adorable. And Iroh absolutely loves watching it, the young boy's struggling brightening his day, even if only a little bit.

First of all, there are the big things, the things Iroh is sure that he is not the only one noticing – like how Zuko seems to always make sure that the girl is within his sight, or at least within earshot. How he jumps whenever Katara so much as seems to be in the need of some help – any kind of help. How he always struggles to speak exceptionally well when he is around her, but usually falls miserably and ends up stuttering. Some of the younger volunteers at camp have picked it up, too, chuckling amongst each other about the Fire prince, who has it so bad, that maybe he should take a cold shower.

And then there are the small things, the things Iroh thinks only he, who knows Zuko and his tells so well, notices. How, when they sit down for meals, the boy, maybe consciously, maybe unconsciously, always sits beside Katara. If the girl moves slightly to her left, Zuko will mimic her. If she steals a glance at something, Zuko will do the same. If she leans slightly backwards, Zuko will change the angle of his back, too. Sometimes when the girl sneezes or yawns, Zuko follows suit. Whatever the young waterbender does, his nephew does the same. Iroh couldn't think of anything more adorable, really.

In some way, it kind of reminds Iroh of some of the lessons he had to sit through as a young prince – he recalls one of his tutors and his detailed model of the Universe, complete with miniature planets made of colorful marbles, and clever, copper levers that made them move. If one planet was moved, the others moved according to it, too, just like their real, mighty counterparts.

These two young people are just like the planets, Iroh muses – they are parts of the same universe, where Katara is the Sun, and his nephew is one of the planets orbiting around her, his world centering around her, every one of his senses attuned to her.

He just hopes that thickheaded nephew of his will realize it soon, too, before it will be too late.
