Chapter Text
The blizzard came down like the sky itself had decided to bury them.
Zuko and Katara had been chasing a rogue waterbender for days. The renegade had been ambushing merchant caravans on the lonely roads outside Zigan village, encasing wagons in thick ice before stripping them of money, food, and anything else worth carrying. Honest traders were left stranded in the snow, hungry and penniless.
The governor of Zigan was desperate and had sent an urgent plea to Team Avatar. Aang and Sokka were busy scrambling to secure vital supplies, while Toph and Suki were grappling with a separate emergency elsewhere in the vast Earth Kingdom. This left only Zuko and Katara available to answer the call in exchange for rare healing herbs and a purse string of gold coins that the governor pledged.
They were deep in the northwestern area outside of the village when the blizzard suddenly hit. One second the trail was wet slush under their mounts’ paws, the next, a howling wall of snow swallowed everything. Weather in this part of the kingdom is unpredictable due to its close proximity to the Northern Sea.
They had known that. They just didn’t think much about it. The trail was fresh, and the ruffian only hours ahead, and neither of them had wanted to slow down long enough to prepare for the unexpected. Now they were paying for it.
Half-frozen and soaked, Zuko and Katara stumbled through the storm with their polar-leopard caribous until they found a small herder’s hut dug into the side of a hill. They went inside, slammed the door against the wind, and stood dripping on the dirt floor—too cold and tired to even glare at each other to who should have packed more provisions or who should have checked the weather signs.
There was one door, one hearth, one table, and (of course) one bed.
A narrow bed, barely wide enough for two if they tried very hard not to breathe at the same time.
After starting a fire at the hearth, Zuko took one look and started unrolling his bedroll on the floor without a word.
Katara, teeth chattering, snapped, “Don’t be an idiot. The floor’s frozen stone and you’re already shaking.”
“I’m fine.”
“You’re turning blue, Zuko.”
“That’s just the light.”
She rolled her eyes so hard it hurt. “Get in bed, prince martyr. I’m not explaining to Aang why I let you lose your fingers to frostbite, and then you won't be able to teach him firebending.”
Zuko hesitated another three heartbeats (long enough for pride, short enough for survival) then kicked off his boots and climbed in, staying as far on the edge as humanly possible. Katara slid in on the opposite side, leaving a canyon of cold air between them. She pulled every blanket over herself like a fortress wall.
Silence. Wind howled against the shutters. The fire in the hearth spat and settled.
Minutes dragged.
Katara’s feet refused to warm. The damp in her sleeves wicked heat away faster than the dying fire could give it. She curled tighter, hugging her own arms.
Zuko lay rigid on his back, eyes fixed on the ceiling, pretending he wasn’t shivering so hard the bed frame rattled.
After what felt like hours, Katara muttered into her pillow, “This is ridiculous.”
“Agreed,” he said instantly, voice strained.
“We’re adults.”
“Technically.”
“We can share body heat without it being… weird.”
A long pause. “Define weird.”
“Oh for Agni’s sake—” She scooted exactly four inches closer, still not touching. “There. We’re sharing an approximate thermal radius. Happy?”
“Ecstatic,” he deadpanned.
Another ten minutes. The fire burned lower. The temperature in the room plummeted.
Katara’s nose was ice. Her toes were going numb. She could actually hear own teeth clacking together.
She huffed. “Turn over.”
“What?”
“Turn over. Back to back. It’s warmer.”
He obeyed with the stiff dignity of someone balancing on the edge of a blade. They rearranged, two ramrod-straight spines separated by a handspan of frigid air. Slowly, slowly, the shared warmth began to build between their shoulder blades.
It was… tolerable.
Katara drifted off first, exhaustion winning over everything else.
Sometime past midnight the fire finally gave up and died.
The cold crept in like a living thing.
In her sleep, Katara chased heat the way a flower turns toward sunlight. She made a small unhappy sound, shifted, and kept shifting until her forehead bumped onto something solid and warm. Instinct took over: she burrowed closer, tucking her iced nose against the crook of a neck that smelled faintly of smoke and wet wool. One of her arms flopped across a narrow waist; her knees curled up behind someone else’s. She sighed, long and content, and went fully under.
Zuko woke the instant her cold nose touched his throat.
Every muscle locked.
Katara’s breath was warm against his collarbone. Her hand had somehow found its way under the edge of his tunic and was splayed, trusting and asleep, over his ribs. Her legs were tangled with his like she’d decided he was her personal furnace.
He couldn’t move. Wouldn’t move.
He lay there staring wide-eyed at the ceiling while the storm screamed outside and told himself, fiercely, that this was purely for survival. Body heat. Nothing else. She was asleep. She would be mortified when she wakes up. He would pretend this never happened and they would never speak of it again.
But she made another small sound (half sigh, half whimper) and pressed closer, chasing warmth even in dreams, and something in his chest cracked straight down the middle.
He stayed perfectly still for the rest of the night.
He didn’t sleep again. He counted her breaths instead. When she shivered, he carefully eased the blanket higher over her shoulder without letting any cold air in. When her fingers curled against his skin, he let them. He told himself it was because moving would wake her and she needed rest. That was all.
He watched the window turn from black to pale gray.
Dawn finally seeped through the ice on the glass. The wind had quieted to a tired moan.
Katara stirred. Her eyes fluttered open, lashes brushing his neck. It took three full seconds for awareness to hit.
She froze.
Zuko closed his eyes and waited for the explosion.
It didn’t come.
Very slowly, Katara lifted her head. He could feel her stare boring into the side of his face. He kept his eyes shut and tried to breathe like a person who had definitely been asleep this whole time.
Katara’s voice, when it came, was a mortified whisper. “Did I… Did I just crawl all over you?”
A beat.
“…You were cold,” he said to the ceiling.
She started to pull away. His arm (traitor that it was), tightened for a fraction of a second before he forced it to let go.
Katara sat up, cheeks flaming, clutching the blanket to her chest. “I’m sorry. I—spirits, I was practically on top of you.”
“It’s fine,” he said, too quickly.
“It’s not fine! You must have been miserable.”
He finally opened his eyes and looked at her. “I wasn’t.”
Two simple words. Quiet. Undeniable.
Katara’s mouth opened, closed. A knowing embarrassment flickered across her face.
Outside, the snow had stopped. Sunlight glittered on fresh drifts taller than the door.
Zuko sat up, clearing his throat. “We should dig out, check to see if the caribous from the governor are still outside.”
“Right,” she said faintly. “Dig.”
They didn’t look at each other while they gathered their things. Katara bent the ice away from the door in furious bursts; Zuko melted a path with short jets of flame.
When the way was clear, Katara paused on the threshold, breath fogging in the bright cold.
She didn’t turn around. “And Zuko? she said facing the snow. “This one stays between us.”
Zuko’s heart did something complicated. “…Agreed.”
Of course he’d write it all down later, scrupulously, in the little leather-bound journal he kept hidden in his pack, because some things like this were supposed to be recorded for history... even if the only person in history that would ever read it was him.
She steps outside.
He followed, boots crunching, the memory of her weight against his chest still warm long after the blizzard had passed.
