Chapter 1: The Unspoken Invitation
Sokka paced.
The polished obsidian floor of Zuko’s private chambers was cool under his bare feet, but it did nothing to soothe the restless heat in his gut. He’d been trying to sleep for hours. The bed in the guest suite was too soft, the silence too complete. All he could think about was the stupid, official-looking scroll on Zuko’s desk, the one containing his own painfully formal request for leave to return to the Southern Water Tribe for the solstice festival. Approved, of course, with Zuko’s elegant, sharp-angled signature at the bottom.
Weeks. He’d be gone for weeks.
A low fire flickered in the hearth, casting shifting orange light over the sparse, elegant room. The scent of sandalwood and the faint, lingering trace of cinnamon from their evening tea usually calmed him. Tonight, it just reminded him of the quiet hour they’d spent together, Zuko frowning over trade ledgers while Sokka doodled absurd improvements to Fire Nation catapults on scrap parchment. Normal. Easy. Everything was about to become not easy.
He stopped at the window, pressing his forehead to the cool glass. Caldera City slept below, a constellation of dim lights. He’d miss this view. Miss the way Zuko’s shoulders relaxed by the third cup of tea. Miss the gruff, unexpected laugh that sometimes escaped him when Sokka’s jokes hit just right.
A soft knock at the chamber door made him jump.
It was too late for servants. Zuko wouldn’t knock. Sokka’s heart did a stupid, hopeful lurch anyway. He crossed the room and pulled the heavy door open.
Katara stood in the hallway, a travel pack slung over one shoulder and a snow-dusted parka hood framing her face. Her blue eyes, sharp as ever, scanned him from his rumpled sleep tunic to his bare feet.
“You look terrible,” she said, breezing past him into the room as if she owned it.
“Katara? What are you doing here? You’re not supposed to be escorting me home for two more days.”
“I finished the negotiations at the North early. Figured I’d surprise you.” She dropped her pack, shrugged off her parka, and immediately zeroed in on the half-empty tea service and the two cups. Her gaze swung to the perfectly made bed, then back to Sokka’s face. A slow, knowing grin spread across her features. “Or. Maybe I’m surprising both of you. Where is he?”
Sokka felt his ears grow hot. “Asleep? It’s the middle of the night. And we were just having tea. Don’t make that face.”
“I’m not making a face. This is my ‘I’m happy to see my brother’ face.” Her expression shifted into something far more scheming. “So. You’re moping around his rooms in the dark. He’s clearly not here, which means you came looking for him and found an empty room. Which means you’re even more pathetic than I thought.”
“I’m not moping. I was thinking. Strategizing. Ambassador stuff.”
“Uh-huh.” She walked over to Zuko’s desk, her fingers trailing over the smooth surface until they rested on the scroll case. She didn’t open it. She didn’t need to. “Worried about going home without him?”
“What? No. Why would I—that’s not—” Sokka spluttered, running a hand through his hair. “It’s a family thing. He’s the Fire Lord. He’s busy. He doesn’t want to come to some freezing festival at the South Pole.”
Katara turned, leaning against the desk, and crossed her arms. “Did you ask him?”
Sokka stared at a particularly interesting crack in the obsidian floor. “It’s not that simple.”
“It’s exactly that simple.” She pushed off the desk and walked toward the inner door that led to Zuko’s personal bedchamber. “He’s your best friend. You miss him when you’re gone. You think Gran-Gran doesn’t want to meet the guy who helped save the world? You think Dad hasn’t been asking about him for years?”
“Katara, don’t—”
She ignored him, rapping her knuckles sharply on the carved wood. “Zuko! You decent? It’s Katara.”
There was a muffled thump, a low curse, and then the door swung inward.
Zuko stood there, hair mussed from sleep, wearing dark linen pants and no shirt. The scar over his left eye seemed more pronounced in the shadowy doorway. His lean, muscular frame was tense, coiled for a threat that wasn’t coming. His eyes, gold and wary, darted from Katara to Sokka, and some of the tension drained away, replaced by confusion.
“Katara. Is something wrong?”
“Nope. Everything’s right.” She beamed at him. “Pack a bag. You’re coming with us.”
The sentence hung in the air between the three of them. Sokka felt his stomach drop through the floor. Zuko blinked, his brow furrowing.
“I… what?”
“To the South Pole. For the solstice festival. I already cleared it with Dad. He’s thrilled. Said the guest igloo is all ready.” Katara’s tone was so casual, as if she’d just suggested a trip to the market. “Sokka’s been driving everyone here crazy with his moping, and you look like you haven’t had a real vacation since you took the throne. So. You’re coming. It’s decided.”
Sokka found his voice, high and strained. “Katara, you can’t just decide—he’s the Fire Lord, he has duties, he doesn’t want to—” His words died as he watched Zuko’s face.
The confusion melted first. Then the guarded, official look he wore like armor every day began to dissolve. His eyes, almost shyly, flickered to Sokka for a second, a silent question. Sokka could only stare back, his mouth slightly open, his whole world narrowed to the man in the doorway.
A slow, deep breath expanded Zuko’s chest. He brought a hand up, fingers rubbing absently over the edge of his scar, a habit he had when thinking. The faintest hint of a smile touched his lips, small and genuine, the one Sokka only saw when he thought no one was looking.
It was directed right at him.
“Okay,” Zuko said, his voice rough with sleep but clear. “Okay, I’ll come.”
Sokka’s heart stopped, then restarted with a painful, thrilling hammer against his ribs. The simple acceptance felt like a landslide. Katara smirked, clapping her hands together once.
“Great! We leave at dawn. Try to pack something warmer than that.” She gestured at his bare torso, then grabbed her parka. “I’ll go bother the kitchen staff about travel rations. You two… figure it out.”
She swept out, leaving a cavernous silence in her wake.
Zuko leaned against the doorframe, the smile lingering. “Your sister is terrifying.”
“Yeah,” Sokka managed, his voice a dry croak. “You really don’t have to do this. She can be bulldozed. I can talk to her.”
“Do you not want me to come?” Zuko asked. The question was quiet, stripped of any Fire Lord inflection. It was just Zuko asking.
“No! I mean, yes. I mean—” Sokka groaned, pressing the heels of his hands into his eyes. “I want you to come. Obviously. I just didn’t think you would. Or could.”
“I can.” Zuko pushed away from the door and took a few steps into the room. The firelight danced over the planes of his chest, the old burns and newer scars, the powerful lines of him. “I’ve wanted to. For a while. I just… didn’t know how to ask. Or if it would be appropriate.”
“Since when do we care about appropriate?”
“I’m supposed to care about appropriate,” Zuko said, but he was still smiling that soft, private smile. “But Katara’s right. I haven’t taken a break. And your father did invite me. Years ago.”
“He invites everyone. He invited the mail hawk once.”
Zuko huffed a laugh, a short, warm sound. He looked at Sokka, really looked at him, and the moment stretched, charged and fragile. Sokka became acutely aware of his own state of undress, the late hour, the sheer enormity of what had just happened.
“So,” Zuko said finally, breaking the gaze to glance toward his room. “Dawn. I should probably pack.”
“Right. Yeah. Warm clothes. It’s… it’s cold.”
“I’ve heard.” Zuko turned to go, then paused. He looked back over his shoulder, the scarred side of his face in shadow, the golden eye catching the firelight. “Sokka?”
“Yeah?”
“Thanks. For wanting me there.”
He disappeared into his bedroom, closing the door with a soft click.
Sokka stood alone in the quiet, flickering dark. The scent of cinnamon and sandalwood was still there, but now it was mixed with the crisp, clean scent of snow from Katara’s parka. The empty scroll case on the desk no longer seemed like an ending. It was just a container for an old question, one that had finally, impossibly, been answered.
He let out a long, shaky breath, a grin spreading across his face that felt too big for the room. Dawn couldn’t come soon enough.
Dawn couldn’t come soon enough. It came, instead, with a brutal efficiency that left Sokka scrambling, his mind still tangled in the soft wonder of Zuko’s smile. Packing was a chaotic blur of throwing warm parkas, gloves, and his boomerang into a travel sack while trying to swallow dry rice cakes. By the time the first true rays of sun painted the caldera walls pink, they were standing in the courtyard, breath fogging in the crisp morning air.
Appa shifted his great weight, his low groan echoing off the stones. The giant bison’s fur smelled of sky and hay. Katara was already settled atop his head, the reins loose in her hands, looking unbearably pleased with herself.
“You remembered your toothbrush, right?” she called down. “Three weeks is a long time to have mossy teeth.”
“I’m an ambassador, not a cave troll,” Sokka shot back, heaving his pack into the saddle. He turned to help Zuko, who was approaching with a single, impeccably packed duffel.
Zuko had reverted to his public uniform—dark red robes, the high collar, his hair now swept back in its formal topknot. The Fire Lord was present, a shield against the unknown. But the bags under his eyes were deeper, and his fingers tightened on his bag’s strap, knuckles white.
“You good?” Sokka asked, quieter.
Zuko just gave a sharp, stiff nod. Sokka took the bag, their fingers brushing. A static jolt, imagined or not, shot up Sokka’s arm. He pretended not to notice, busying himself with securing the luggage.
The flight began in a comfortable, familiar silence, the rhythmic sway of Appa’s gait and the slow, powerful beat of his tail soon lulling them into the journey’s rhythm. Caldera City shrank to a toy model below, then vanished behind mountain peaks. The world opened into vast, blue sky and the glittering ocean.
Sokka relaxed incrementally, stretching out on the saddle and watching clouds drift past. This was good. This was normal. Just friends on a trip.
Then Katara, without turning from her steering, shattered the peace.
“So, Dad’s latest letter,” she said, her voice carrying easily over the wind. “He says the whole village is buzzing. Well, as much as twenty-seven people can buzz.”
Sokka propped himself up on his elbows. “Buzz about what? Did someone finally invent a better seal-gutting knife?”
“About Zuko coming.” Katara glanced back, her grin wicked. “They’re not excited to meet the Fire Lord, you know. I mean, that’s part of it. But mostly, they’re excited to finally meet the important man in Sokka’s life. Gran-Gram’s been speculating for years. She has a betting pool with some of the aunties about your ‘mysterious, brooding pen pal.’”
Sokka’s entire body flushed with a heat that had nothing to do with the sun. He sat bolt upright. “Katara! What the—they don’t—I never said—”
“You didn’t have to. Your letters home are, like, seventy percent ‘Zuko said this’ and ‘Zuko did that’ and ‘Zuko’s trying to reform the agricultural subsidies, it’s so noble.’” Her impression of him was painfully accurate. “You’re not subtle, brother. The entire South Pole thinks you’re practically married.”
Sokka wished, fervently, that Appa would suddenly dive into the sea. He couldn’t look at Zuko. He stared fixedly at a stitch in the saddle. “They have the wrong idea. It’s a political relationship. A strategic alliance. A—a fraternal bond!”
“Uh-huh.”
A soft, low sound came from beside him. Sokka dared a glance.
Zuko had been staring out at the horizon, his profile stern. But at Katara’s words, the rigid line of his shoulders had loosened. The taut skin around his scar had smoothed. His lips, usually pressed in a firm line, were curling upward. It wasn’t the small, private smile from the night before. This one was fuller, brighter, tinged with amused wonder. It transformed his entire face, softening the severity, lighting his gold eyes from within.
He didn’t look at Sokka. He just kept smiling at the sky, as if he’d been given a gift he hadn’t dared ask for.
The sight stole the breath from Sokka’s lungs. His mortification was still there, a hot coal in his chest, but over it spilled something else, something terrifying and warm.
“See?” Katara said, her voice dropping to a conspiratorial tone. “He gets it. Anyway, logistics. Space is tight with all the cousins coming in. So, you two will be rooming together in the same guest igloo. It’s the nicest one, right next to Dad’s. I figured it made sense, since you’re so close.”
The air left Sokka’s lungs in a soft whoosh.
Rooming together.
Sharing an igloo.
Weeks.
The same enclosed, private, intimate space. Sleeping mats laid out side-by-side in the gentle blue gloom. The quiet sounds of breathing in the dark.
Zuko’s smile didn’t fade. He finally turned his head. His gaze met Sokka’s, holding it. There was a question there, and a shared, dizzying understanding. The formality of the Fire Lord’s robes seemed to dissolve in that look.
“That,” Zuko said, his voice perfectly even, “sounds efficient.”
Appa soared on, carrying them north into the cold, bright future. The wind whipped past, but between them, the air was suddenly, profoundly still.
