Chapter Text
Morning came the way everything else did in the western air temple, quietly, through broken stone and open sky, wind slipping through the corridors and creating a soft whispering background of sounds.
Sokka, Katara, Aang and Toph found themselves all sleeping in one room as a group. It had happened without verbal discussion when on the first evening they arrived, each one had set up their bedroll against one wall of the room. When the first of them woke in the morning, it didn’t last long until the whole group stirred and got started on the daily routine that had established itself as quickly and naturally as their sleeping arrangement.
They spent the first hours of morning together, eating, meditating, reading and discussing plans for the day before each of them scattered to their own activity.
Sokka liked to keep himself moving. He planned things that might or might not happen. Drew routes in the dirt. Checked supplies. Practiced his swordwork until his muscles burned in a way that made him feel productive and the world a little more manageable.
Toph disappeared and reappeared on her own terms, usually announcing her presence by insulting someone.
Katara carried their group in a way she pretended not to, always aware of what needed doing before anyone else noticed it was falling apart.
In the evening they rejoined. They gathered around the fire in the open courtyard, where the temple walls broke into sky. The fire was usually Sokka’s job, at least, it had become his job without anyone explicitly assigning it to him. It made sense. He liked it. There was something steady about it, something that made the world feel briefly understandable.Once it caught, it became the center of everything.
That was when the day finally belonged to them.
No training. No planning. No urgency sitting behind their eyes. Just food shared without counting, jokes that didn’t have to lead anywhere, arguments that faded as quickly as they came. Aang would laugh at something Toph said and nearly spill his drink. Katara would scold someone, but not seriously. Sokka would say something ridiculous just to see if he could get a reaction out of anyone, and usually he could.
Sokka liked their evenings the most.
When Zuko joined, he moved into his own room, separate from their sleeping quarters, but he did become a part of their routine.
Aang trained with Zuko in the mornings now, something Sokka still wasn’t sure he would ever get used to. They moved across the courtyard with a kind of sharp focus that made everything else feel distant. Aang trying, falling short, trying again. Zuko correcting him in clipped instructions that sounded like they belonged to a different life entirely. Sometimes Katara joined them, arms crossed, eyes narrowed, stepping in when she thought Aang was overextending himself, always having a watchful eye on their newest member of the group.
Sokka found himself watching him as well, more than he meant to.
Not because he liked Zuko. That wasn’t what it was. It was just… harder not to notice someone who looked like they were constantly standing at the edge of something. Sokka watched him the way he watched anything that could suddenly turn into a problem: like a storm cloud that hadn’t decided yet whether it was passing over or about to break open. Zuko didn’t act like he belonged, exactly. He acted like someone temporarily occupying a space he expected to be taken away again.
Zuko joined them in the evenings too, in his own way. While the fire pulled the rest of them into its circle naturally, Zuko didn’t follow that shape.
He chose his place the way someone might choose a lookout point. His back against the temple wall, close enough that the fire still reached him, warmth touching the edge of his boots, light catching on the lines of his face, but never quite close enough to be folded into the group without effort. He would sit slightly off to one side of the circle, angled just enough that he could see all of them at once without fully turning toward any one person.
It wasn’t dramatic. It wasn’t even obviously intentional at first glance. Just a few feet of distance. Close enough to not sit by himself, but far away to not entirely be part of their group.
Sokka noticed it in the way he noticed most things about Zuko, not as a single decision, but as a pattern of small, repeated choices. The way Zuko never fully leaned back into relaxation, even when the firelight softened his shoulders. The way he listened more than he spoke, as if words were something to be measured before they were allowed out.
Sometimes, when the conversation got loud enough, when Aang laughed too hard or Toph started arguing with Katara just to see what would happen, Zuko’s attention would sharpen for a moment, eyes tracking the movement of the group like he was still learning what safety looked like when it wasn’t quiet.
Surprisingly fast, Sokka started noticing that the space Zuko kept was no longer fixed.
At first, it was almost nothing. Zuko still sat at the edge of the fire in the evenings, still kept that careful distance between himself and the rest of them. But over time, that distance started to shift. Not in any dramatic way. Just a subtle closing of space, like someone inching closer to warmth without fully admitting they were cold.
One night he sat a little nearer than he had the night before. Another night, closer again. Not enough for anyone else to comment on it. Just enough that Sokka started to notice the difference in how the circle felt when they all settled in.
And sometimes, when the night stretched on and the group got louder, when Aang laughed too brightly at Sokka's joke that made Katara roll her eyes, Zuko didn’t sharpen the way he used to. Sometimes, Sokka could even imagine to see the smallest of smiles.
The night always ended in the same way. One of the group would get up, announcing they were going to sleep and it wouldn’t take long for each one of them to get up and make their way to their room afterwards. Each one of them, except for Zuko, that was. Sokka had formed a habit of being the last to leave, putting out his fire while Aang, Katara and Toph got ready for bed.
Since Zuko had joined them, he didn’t need to put out the fire anymore. Every night, when he left to join the others, he looked over his shoulder just before entering their room. And each night, Zuko was still sat there.
With the watch he kept of the firebender, he noticed different things as well.
Like how Zuko was always up early.
Sokka would stumble out of their room in the morning, yawning after a particularly targeted line of sun had driven him awake before his time and find the firebender outside, already awake, always practicing bending forms, pacing around or fidgeting with his blades.
Once, when Sokka made a passing comment about it, Zuko had just shrugged. “Firebenders rise with the sun,” he said, like it was obvious. Sokka wasn’t convinced it was that simple. Because it wasn’t just that Zuko was awake early. It was that he looked like he had never really stopped being awake.
It occurred to him that he had indeed never seen the firebender go to sleep.
Sokka started noticing it the way you notice a rope fraying, one strand at a time, until suddenly you can’t pretend it’s the same rope anymore.
At first it was subtle.
A longer pause before Zuko answered a question. A blink that lingered half a second too long, like his mind had briefly stepped out of the room and was only just returning. Nothing anyone else seemed to catch. Nothing that broke the rhythm of the day.
Then it started to show more clearly.
During one of Aang’s training sessions, Zuko had been explaining a technique, something about stance and breath and control, and Aang had nodded like he understood. The next day, Zuko explained the exact same thing again.
Aang blinked. “You already told me that.”
Zuko paused, for just a second too long.
Then, flatly, “No I didn’t.” Aang hesitated. “Yes… you did.” The silence that followed wasn’t loud, but it was sharp enough that Sokka felt it from where he stood nearby. Zuko frowned slightly, like he was trying to hold onto a thought that kept slipping out of reach. Then he shook it off and moved on, but something about it lingered in the air after.
Day by day, Zuko looked less like someone sharpening himself for training and more like someone trying to hold himself together through it.
By midday, it showed in training.
Zuko was still sharp, sometimes too sharp. But the sharpness wasn’t clean anymore. It came with edges of irritation that didn’t belong to the moment. Aang would make a mistake, and Zuko would correct him too fast, too tightly, like the mistake itself had offended him. Then he’d stop, just slightly too late, like he’d only realized after speaking that he didn’t need to be that harsh.
Sokka started noticing how often that happened. Not just the corrections,but the correction after the correction. A pause. A tightening of his jaw. A flicker of something in his eyes that looked less like anger and more like strain trying to pass itself off as control.
Even Katara had started reacting to it more often, her head lifting at sharper tones, her voice cutting in when Zuko pushed too far.
And Zuko would stop. But not fully soften. Just… rein it in. Like something inside him was being pulled too tight and refusing to stay comfortably contained.
Sokka noticed, too, how Zuko’s attention started slipping in ways it hadn’t before. Small things. Standing still too long after a conversation ended, like he wasn’t sure what he was supposed to do next. Looking at someone speaking and not quite processing it right away, as if the words were arriving slightly out of sync with his thoughts.
It wasn’t obvious from a distance. To most of the group, Zuko still just looked like Zuko. Brooding. Intense. Easily set off.
But Sokka was starting to see the difference between anger and exhaustion.
And Zuko was starting to look more like the second one pretending to be the first.
He noticed another thing. In the evenings, when they were sat together.
The fire had burned down to a steady, low glow, the group scattered in their usual loose circle. Conversation came in bursts, Aang telling some story the monks used to tell him when he was younger, Toph half listening while occasionally sending a pebble against the side of Aang's head when he wasn’t paying attention to his surroundings and Katara sorting through their supplies with distracted focus. Zuko sat in his usual spot across from Sokka, his back against the wall of the temple.
Sokka was the only one watching him closely enough to notice the shift. It started small. Zuko’s posture, usually controlled even when he was quiet, loosened by a fraction. His head leaned back against the stone behind him. He was blinking slowly, his eyes sometimes staying closed for a few seconds at a time.
At first, Sokka thought he was just tired in the way he’d been getting used to noticing.
But then Zuko went still. Not tense still. Not alert still.
Just… still.
His head tilted back, the firelight flickering across his face while his eyes remained closed.
Sokka froze.
Around them, nothing changed. Aang was still talking, Katara still sorting. No one else noticed.
Zuko's breathing evened out, just slightly too slow to be anything but sleep. His posture held for a few seconds like his body was still trying to convince itself it was awake, then it gave in like it had been waiting for this moment. Zuko’s right hand slipped from his knee where it had previously been resting and his mouth opened just the tiniest fraction. His expression, without the sharpness or tension, looked younger in a way Sokka hadn’t expected. Less guarded. Less prepared for anything to go wrong. He looked like a teenage boy, not like the angry prince that had been chasing them not too long ago.
After a moment of watching him, Sokka made himself look away. He did his best to look at Aang and listen to his story, but couldn’t help glancing at the sleeping boy across from him.
For a while, nothing happened.
The fire burned low and steady between them, wood settling in soft little pops that barely disturbed the night. Aang kept talking and Toph interrupted just enough to make Katara sigh without looking up from what she was doing.
The conversation drifted around the circle the way it always did.
And through all of it, Zuko slept. Not deeply. Not sprawled out the way Aang sometimes did when he nodded off too close to the fire. But asleep all the same.
Sokka kept trying not to look. He would force himself to focus on Aang’s voice for a few sentences, on the shape of the flames, on the feel of the cool stone beneath him. Then his eyes would pull back almost without asking him.
Zuko hadn’t moved. His head was still tipped back against the wall. One hand loose at his side. His breathing slow and even.
The longer it went on, the stranger it felt. Not because Zuko was sleeping.
Because no one else noticed.
Katara glanced past him once while reaching for something and kept talking. Aang didn’t break the flow of his story. Toph, somehow, either hadn’t registered it or had decided it wasn’t worth mentioning. Only Sokka sat there with the odd awareness of it.
It went long enough that it stopped looking accidental. Long enough that Sokka started feeling something shift into place in the back of his mind, though he couldn’t quite name it yet.
Time passed, Aang’s story had ended and he and Katara started gathering their things to get up.
Then Zuko stirred.
It was small at first, a deeper breath, the faintest movement of his shoulders. His fingers curled once against the stone. His head shifted a fraction, like he was surfacing reluctantly from somewhere further away than he’d meant to go.
Then his eyes opened. Not sharply. Not with the immediate alertness Sokka had gotten used to.
Slowly.
For one disoriented second, Zuko just blinked at the fire. And then he looked up.
Straight at Sokka.
The eye contact caught so suddenly that Sokka forgot to look away.
For a moment neither of them moved. The fire cracked softly between them. Aang was still talking somewhere to Sokka’s left, but his voice had gone distant, like it belonged to another part of the courtyard. Zuko’s face changed almost at once. Not all the way back into the usual guarded expression, but enough. He straightened a little, mouth closing, hand returning automatically to his knee as if putting himself back together.
His eyes narrowed the tiniest fraction. Not angry. Just… aware.
He knew.
He knew Sokka had seen.
Sokka felt strangely caught at it. Like he had stumbled into something private without meaning to. He should have looked away then. Made it easier. Instead, without really thinking about why, he gave the smallest lift of his chin, nothing more than a quiet acknowledgment.
Something in Zuko’s expression shifted again. Very small. His shoulders didn’t tense the way Sokka expected them to. He didn’t immediately stand, didn’t leave, didn’t shut down completely. He just held Sokka’s gaze for one second longer than he had to.
Then he looked back toward the fire. And after a beat, so did Sokka.
Neither of them said a word. But now Sokka knew something he hadn’t known before.
Zuko had fallen asleep here. With all of them around him. And when he woke, he hadn’t looked startled. Only caught.
