Like Fire and Moonlight - Chapter 01: The Return to Hogwarts

It was barely past nine when Harry Potter stepped out of the Ministry car, a shine still on his dragonhide boots and a practiced grin already climbing into place. The morning was crisp in the kind of way that made everything look sharper than it felt — the cobblestones beneath his feet, the scarlet steam drifting off the Hogwarts Express, the way strangers’ eyes flicked instantly toward him before they had the decency to pretend they weren’t watching. He could feel it like a second heat on his skin: the stares, the nudges, the whispering there he was rising through the crowd like static. Seventh year. Final round. The golden boy of Gryffindor returns.

He straightened, shoulders back, chin tilted at just the right angle — polished without seeming too stiff. Nearby, someone snapped a photo with a small crackle of light; he didn’t flinch. Instead, he turned slightly, caught the lens with a flick of his eyes, and let the corner of his mouth tilt in something just rakish enough to be reprinted. James would kill him later. Or grin. Hard to say.

“Stop posing,” Lily murmured under her breath as she stepped beside him, gently tugging at the sleeve of his cloak like she had since he was nine. Her red hair, streaked now with silver, was twisted into a high knot that made her look like some battle-hardened academic empress — all grace, no softness, except in the way she looked at him. Her fingers fussed over his collar like he was still fifteen. “You’ll make the cover again and your father will throw a fit.”

“He’ll love it,” Harry said without turning. “They’ll get on my good side this time.”

“You only have the one,” came a voice from behind them. James Potter — Senior Auror, Ministry darling, wand-slinger and world-class pain in the arse — approached with the slow, unhurried pace of a man who had no intention of helping with trunks but every intention of judging your posture. His robes were regulation black with the faintest burn mark at one cuff; he wore it like a badge. “Next time you show up in that Witch Weekly column, I’m going to have your wand confiscated.”

“You’ve been threatening that since fifth year,” Harry replied, but the smile was tight. He loved his father — in that abstract, weathered way that sons love fathers who never quite stopped treating them like junior cadets. James had taught him how to duel, how to drink firewhisky without coughing, how to walk into a room like it owed you a favor — but he’d never quite managed the softer bits. Every compliment was camouflaged as a joke, every concern framed as an order. Harry didn’t mind, not really. It just made everything feel... a little like boot camp.

“He looks good,” Lily said pointedly, her hand still at Harry’s elbow. “Doesn’t he look good, James?”

James grunted, scanning his son like a field report. “He looks like a bloody headline. Try not to embarrass us. Or impregnate anyone.”

“Mum,” Harry said, nearly choking.

Lily patted his cheek. “We’re proud of you,” she said, low enough that only he could hear. “Just don’t let them turn you into a statue. You’re not a legacy. You’re you.”

That hit harder than he liked.

A whistle shrieked from the far end of the platform. All around them, students scrambled toward the train in flurries of hugs, last-minute trunk-slamming, owl-box juggling, and wand-forgetting chaos. The crowd became a tide. Harry took one last look at his parents — his mother elegant and tired, his father already glancing at his pocket watch — and forced a grin.

“Seventh year,” he said. “What could possibly go wrong?”

James snorted. “You could end up partnered with a Slytherin.”

Lily’s smile faltered — just slightly, just enough that Harry noticed.

“I’ll write if I’m arrested,” Harry said breezily, then swung his bag over his shoulder and stepped up into the train, golden and grinning and already pretending he didn’t feel the first crack in his armor.

~HP~

The Hogwarts Express had always smelled the same — a heady mixture of worn velvet, buttered pastry, adolescent sweat, and owl feathers — like chaos trapped in red velvet walls, reheated every September. Harry moved through it like it was second nature, nodding at wide-eyed first-years and ducking past upperclassmen who clapped him on the back like they were old war buddies. He performed the part with effortlessness, each smirk and wave finely tuned from years of attention. He could recite the script now: grin, joke, look slightly exasperated by the attention while secretly soaking in the heat of it. Let them think he was tired of being admired. Let them love him for hating it.

He found Ron and Hermione in their usual compartment near the middle of the train — Ron already halfway through a treacle tart, Hermione with a neatly ordered stack of parchment balanced on her lap like she was preparing for a trial rather than a train ride. Harry slid the door open with a grin and no warning.

“Did you miss me?”

Ron looked up, crumbs on his cheek. “I thought I smelled ego.”

Hermione didn’t glance up. “I was hoping for thirty minutes of peace before you started antagonizing the train.”

“Better get used to disappointment,” Harry said, collapsing onto the seat across from them with a theatrical sigh that jostled Hermione’s stack and made Ron laugh through a mouthful. Outside the window, the platform was beginning to pull away in a slow, lurching crawl. The landscape was a smear of grey station stone and bright cloaks and last-minute hand waves.

Harry let himself settle back into the seat, arms folded behind his head, boots up on the edge of the seat until Hermione kicked them down. This — this part — was comfortable. Banter like worn denim. Ron, still lanky and sunburned from a summer of backyard Quidditch with his brothers, grinning at nothing. Hermione, already talking about the new syllabus and what they were supposed to be reading for Magical Ethics and Legacy Studies — a brand-new class she was practically vibrating over. It was always like this. Predictable, familiar, a soft echo of what Hogwarts used to be before things started feeling tight around the edges.

Hermione was explaining something about the new inter-house structure — “...it’s meant to encourage long-term collaborative empathy and reduce behavioral house bias, especially among upperclassmen, which is honestly overdue if you ask me, though I do think pairing students randomly is asking for disaster, but I suppose that’s the point...” — and Harry let her words wash over him like background music. He watched the countryside flicker past through the window instead, his own reflection faint in the glass: black hair slightly too neat (Lily), shoulders broad (James), eyes tired in a way no one ever seemed to comment on.

“I heard they’re pairing Gryffindor seventh-years with Slytherin prefects,” Ron said suddenly, wiping his hands on his robes.

Harry blinked. “You heard from who?”

“Ginny. Or Seamus. Or both. Or the girl in Flourish and Blotts who tried to sell me a bookmark with your face on it.”

Hermione rolled her eyes. “It’s true,” she said, pulling a scroll from her bag. “McGonagall’s been planning it all summer. It’s part of her new ‘post-war unity initiative’ — even though there wasn’t a war. Just paranoia, and egos, and a lot of house points lost over dramatic speeches.”

Harry smirked. “You’d have made a great Slytherin, you know.”

Hermione didn’t take the bait. “They’re calling it The House Concord. Each house has to nominate two upper class representatives to lead cross-house community events. You, Harry, are obviously one of Gryffindor’s.”

Ron made a low whistle. “Better hope you get stuck with a Ravenclaw. They at least do their homework.”

“Or Hufflepuff,” Hermione added. “If you’re lucky.”

Harry stretched again, feigning disinterest. “Who do you think they’ll saddle Slytherin with?”

Hermione looked up at him over the rim of her scroll. Her expression said she already knew something he didn’t. “You’ll find out soon enough. Prefects are being called to the front carriage. You might want to get moving.”

“Already?” Harry sighed, hauling himself up with exaggerated effort. “Tell McGonagall I’d rather be crucio’d than partnered with Greengrass.”

“She might take that as a formal request,” Hermione murmured, not looking up.

Harry grinned, but it was all surface — because the truth was, somewhere under the grin and the swagger, the idea of Daphne Greengrass being even remotely close to his academic orbit made something cold twist low in his stomach. She was all angles and silks and silence. The kind of girl who could undo you with a single glance and never blink as you crumbled. And if there was one thing Harry Potter had never learned to handle, it was someone who saw straight through his charm.

He didn’t know, as he stepped into the corridor, that she already had.

~HP~

The prefect carriage was always warmer than the rest of the train, whether by some subtle spell woven into the woodwork or the sheer body heat of entitlement. The cushions were thicker, the trim real brass, the enchanted lanterns above casting a soft golden light designed to flatter even the most sour-faced sixth-year Slytherin. Harry had spent enough years wandering in and out of it to know the script: smile like you don’t need to be here, joke with the younger prefects, let Hermione do the actual organizing. Usually, he’d arrive five minutes early just to stretch his legs across one of the good armchairs before anyone else could take it. Today, he was late by design. Nothing telegraphed power like showing up just after everyone was forced to wait.

He tugged open the door with casual flair, arm slung lazily across the handle, and stepped inside like a storm in search of something to ruffle—only to find the room quiet. Empty, nearly. One person was there ahead of him, alone, and entirely unmoved by his arrival.

Daphne Greengrass sat near the far window in a position that could only be described as precisely correct. Her spine straight, one leg crossed elegantly over the other, a slim green-bound book floating beside her shoulder, suspended by a lazy wandless charm as she sipped from a porcelain cup that was far too sophisticated for train tea. The window’s filtered sunlight brushed a silvery sheen over the cool tones of her outfit: a high-collared blouse the color of crushed sage, black trousers pressed to perfection, polished shoes with a discreet serpent clasp glinting at each ankle. Not a wrinkle. Not a strand of her pale-blonde hair out of place. She looked like she’d stepped out of a pureblood etiquette handbook and had merely deigned to sit here for the benefit of lesser creatures.

Harry had seen her before, of course—across common rooms during prefect meetings, at Quidditch matches where she sat like a sculpture in the Slytherin stands, never cheering, only watching. He’d heard the way people talked about her: cold, brilliant, untouchable. But until this moment, he had never been in a room with her where it was just the two of them and the silence between them had nowhere to hide.

She did not look up.

“You’re late,” she said mildly, as if commenting on the weather, and turned a page in her book with the flick of one long, unbothered finger.

Harry blinked once, then let his grin slide into place like a weapon. “You’re early.”

“I’m punctual,” she corrected without inflection. “It’s different.”

She still hadn’t looked at him. He could see the curve of her cheekbone from this angle, the barely-there shimmer of something expensive at her throat. There wasn’t a single tell in her posture—no twitch of irritation, no glance toward the clock, no visible satisfaction at catching him late. She wasn’t trying to win. She already had.

Rather than concede the silence to her, Harry strolled over to the refreshments cart and poured himself a cup of tea that tasted exactly as bland as he expected. He didn’t sit, not yet. He wanted to test how long it would take her to acknowledge his presence in any way other than as a mildly disappointing footnote.

“I don’t think we’ve ever been properly introduced,” he said, letting his voice carry just enough to be irritating. “Though I feel like I’ve seen you scowling from a lot of balconies.”

Daphne’s eyes lifted then, slowly, deliberately, and met him.

They were grey—not the dull grey of rain clouds, but the sharp, polished kind found in obsidian or steel. Her gaze was so calm it bordered on disdainful, and yet there was something surgical about the way she looked at him. Like she was measuring things no one else bothered to notice. Depth. Leverage. Cracks.

“I don’t scowl,” she said. “I analyze.”

“Right,” Harry said, sipping the worst tea in Britain. “That’s what I do when I watch Quidditch: analyze with contempt.”

A pause. Then, finally, the faintest curve at the edge of her mouth—not quite a smile, not enough to claim. More like an acknowledgment. A tick in a box labeled sentient.

“You’re louder than I expected,” she said.

“And you’re colder.”

“Are you always this obsessed with thermodynamics in your first conversations?”

Harry tilted his head. “Only with people who think the world owes them silence.”

“Only with people who think the world owes them attention,” she countered, and this time, the ghost of a smile did reach her eyes.

It wasn’t warm. But it was real.

Harry sat down across from her, careful to stretch his legs just enough to invade the edge of her space. She didn’t move. Instead, she set her cup down gently on the saucer beside her and returned to her book, utterly unruffled.

But she’d looked.

And that, Harry thought, might be the first point on the board.

~HP~

The tension in the carriage hadn’t softened by the time the door creaked open again with a gust of cooler air and the brisk authority of heeled boots on polished floor. Deputy Headmistress McGonagall entered like a storm in perfect formation — not angry, not flustered, but moving with the sharpness of someone who had spent the summer drafting contingency plans for every conceivable disaster involving magical adolescents, and now had to implement one because no one else had the spine to do it right. Her tartan robes snapped slightly as she crossed the compartment, her lips drawn in a line so precise it might have been spelled into place.

Harry sat up straighter instinctively, the grin flickering just a degree toward sheepish. Daphne didn’t shift at all — she simply turned a page in her book and looked up with the serene, poisonous calm of a queen about to be inconvenienced.

“Mr. Potter, Miss Greengrass,” McGonagall said without preamble. “Good. I expected both of you would be here, though not necessarily at the same time.”

Harry opened his mouth — perhaps to make a joke about punctuality, perhaps to charm a smile out of her — but one look at her expression and he thought better of it. Daphne folded her hands neatly in her lap, posture immaculate, gaze flat.

“Before I get to the point,” McGonagall said, sliding a folder from inside her robes and setting it on the nearest side table, “let me be clear: this is not optional. There will be no appeals, no owls sent home to protest, and no dramatic refusals to participate in front of your respective Houses. You’ve both been chosen. You will both do your jobs.”

That was enough to kill whatever flicker of banter had been crawling up Harry’s throat. He exchanged a glance with Daphne — not surprise, not curiosity, but something closer to resignation. Whatever was coming, neither of them had volunteered for it. And McGonagall had just made it very clear: this was about duty, not desire.

“You two,” she continued, drawing herself up like a tower about to cast shade, “will be the student co-leads for this year’s House Concord Initiative. You will organize all cross-house events. You will manage inter-house volunteer programs. You will deliver regular progress reports to staff. And—” she pinned them both with a look sharp enough to transfigure steel, “—you will do so without hexing each other in public.”

Harry blinked, absorbing the weight of what she’d just dropped. The words filtered through a little slowly, not because they were complicated, but because they were unexpected in the worst way. House Concord. Cross-house events. Co-leads. And not with Hermione or a friendly Ravenclaw or some laid-back Hufflepuff who’d smile awkwardly and do all the paperwork. No. With her.

Daphne’s voice broke the silence first — smooth, unhurried, and laced with veiled protest. “Professor,” she said, tone deceptively polite, “while I’m honored to be selected, I’m not sure pairing us is the most... productive choice. Our skill sets don’t complement one another. There are others in Slytherin more aligned with the goals of public cooperation.”

Harry snorted before he could help himself. “She means I’m loud and she doesn’t like loud.”

Daphne didn’t dignify that with a look. “I mean you lack precision. And foresight.”

“Charming,” Harry muttered. “You must have fun at birthdays.”

McGonagall raised one hand like a judge silencing an unconvincing duel. “Enough. The purpose of this initiative is not to indulge comfort. It’s to challenge bias, reshape culture, and establish precedent. You two,” she added, tapping the folder once for emphasis, “represent opposite ends of Hogwarts’ fractured identity. And if you can work together, others will follow.”

Daphne’s lips parted slightly, as if to deliver a further argument — one that would certainly be devastating in both syntax and tone — but then, very carefully, she closed her mouth. Her eyes flicked briefly toward Harry, as if calculating the precise cost of protest, then back to McGonagall. When she finally nodded, it was slow, deliberate, and more of a concession to logic than agreement.

“Understood.”

Harry watched her with reluctant fascination. He hated the way she carried herself — like she was five steps ahead of every conversation — but he couldn’t help noticing how easily she made silence feel like strategy. She hadn’t accepted anything. She’d just decided that rejecting it wasn’t efficient.

“Any questions?” McGonagall asked, already sounding like she hoped there weren’t.

Harry shrugged. “Do we get badges?”

“You get weekly evaluations,” McGonagall replied, and her glare suggested she’d enjoy failing him.

With that, she turned on her heel and left, robes swishing behind her like an exclamation point. The door clicked shut. The carriage was quiet again — except now, the quiet didn’t feel like a vacuum. It felt like a fuse.

Daphne stood slowly, adjusted the cuffs of her blouse with fingers that moved like she was putting on armor. Then she looked at him — properly, directly, as if seeing him for the first time not as a tabloid figure, but as a problem to be managed.

“Fine,” she said, voice cool and unbothered. “We’ll work together. But let’s get something clear.”

Harry tilted his head. “Do tell.”

“I don’t like you.”

He smiled, wide and easy. “Well, at least we’re starting with honesty.”

She said nothing else. She didn’t have to. She simply gathered her book, her tea, and her silence, and exited with the kind of grace that left no door open for pursuit.

Harry sat back, exhaled slowly, and stared at the now-empty seat across from him.

This was going to be hell.

~HP~

The door hadn’t even clicked shut behind her before Harry let out a breath he didn’t know he’d been holding, dragging a hand through his hair in an unconscious gesture he knew would make Hermione sigh. This wasn’t what he’d expected from his final year. He was supposed to spend it coasting through Quidditch victories, dodging homework through sheer charm, maybe shagging someone in a forgotten classroom and making Ron deeply uncomfortable. Not being partnered with the Slytherin queen of passive aggression and haute couture in a year-long enforced truce while the staff watched for signs of a Hogwarts renaissance.

The thing that bothered him most — and he hated admitting it, even internally — was how unshakeable she’d been. Most people reacted to him. Laughed, blushed, bristled, snapped. Daphne Greengrass had absorbed his presence like fog over a lake: quiet, unmoved, and eventually disappearing without a ripple. It shouldn’t have intrigued him. But it did. And that was inconvenient.

He made his way down the corridor, letting the chatter of students wash over him without absorbing much of it. First-years squeaked by in droves, carrying trunks too large for their arms and wide-eyed awe like it might protect them. A pair of third-year Ravenclaws were arguing loudly about a botched levitation charm and whose fault it had been. Someone was already selling enchanted toffee from behind a Transfiguration textbook. It was all normal, wonderfully so — which made the memory of Daphne’s voice, smooth as silk dragged across a blade, stand out even more.

He found the Charms Hall carriage near the center of the train, where several third-years had already gathered in mixed-house pairs, looking awkward and half-asleep. As part of their new initiative duties, Harry and Daphne were meant to oversee these early cross-house practice sessions — encourage teamwork, correct spellwork, discourage any wand-dueling that bordered on blood sport. He expected her to be late — dramatic exits usually required dramatic returns — but no, of course not. She was already there. Naturally.

She stood at the far end of the makeshift classroom, speaking quietly to a cluster of students in yellow and blue, her tone so measured it made Harry feel like he was being graded from across the room. She wore her authority like perfume — not overwhelming, but lingering, intoxicating, impossible to ignore. When she turned at the sound of the door, her eyes flicked to him without greeting.

Harry plastered on his most irritating smile and clapped his hands. “Alright, you lot. Today’s exercise is mutual humiliation, otherwise known as Charms pairing. Pick someone you don’t know, and preferably someone who won’t hex your eyebrows off.”

There was a ripple of laughter, mostly from Gryffindors. A few Slytherins narrowed their eyes. Daphne said nothing. Her expression didn’t shift — not disapproving, not amused, just... unreadable. He hated that. He preferred his audience loud, impressed, or outraged. She was none of the above.

As the students partnered up and began their feather-levitation exercises, Harry moved among them, correcting wand angles and posture, throwing in the occasional joke that made some of the girls giggle and a few of the boys roll their eyes. It was familiar territory. He could do this in his sleep. Charm them — literally, metaphorically — and keep everything light.

But then, because fate had a cruel sense of humor, one of the Slytherin boys pointed his wand a little too sharply during a flick and sent his partner’s quill hurtling into the air with enough force to knock over two desks and a cage of pixies someone had inexplicably brought along. Shouts broke out. Feathers and glitter exploded. The quill stabbed itself into the ceiling and sparked violently.

Harry stepped forward, raising his wand, but before he could say a word, Daphne was already moving — not fast, not dramatic, just precise. Her wand flicked once, twice, elegant as a conductor. The quill stilled midair, the glitter vanished, the pixies floated neatly back into their cage, and the desks returned to their original positions with a sound like satisfied furniture. Silence followed, stunned and oddly reverent.

She turned to the student, tone glacial. “If you’re going to cast with arrogance, at least have the skill to support it. Sloppy spellwork is embarrassing. For you and for your House.”

The boy flushed a deep red. Harry raised a brow, somewhere between impressed and mildly alarmed.

“Subtle,” he murmured, stepping beside her as the class quietly resumed.

Daphne didn’t look at him. “They respect structure. Chaos makes them defensive.”

“And what do you respect?”

She glanced at him then, just once, and it was enough to make the space between them feel several degrees warmer.

“Results.”

Harry might’ve said something clever if a small voice hadn’t interrupted from behind them — a third-year Hufflepuff girl barely tall enough to reach her own wand. “Um. My partner says I’m bad at this, but he’s just bossy and doesn’t listen. I don’t want to do spells with him anymore.”

The boy next to her scowled, cheeks red.

Before either Harry or Daphne could respond, the girl added, “But you two don’t seem to like each other and you work fine.”

Daphne blinked.

Harry laughed.

And just like that, something shifted — not loudly, not dramatically, but with the quiet certainty of friction giving way to momentum. He looked at Daphne, ready to offer a quip, but she spoke first, low and dry.

“That’s debatable.”

Still, she stepped forward, knelt slightly, and began walking the girl through the proper wand movement — slow, clear, patient. Harry followed her lead without being asked. Together, without planning it, they demonstrated the charm side by side. Their timing was precise. Their words, in sync. The feather rose, hovered, and landed between them without a sound.

Later, when the students had dispersed and the train began to slow in anticipation of their arrival at Hogsmeade, Harry and Daphne stood before the assembled group, wands tucked away, matching expressions of polished indifference hiding the faintest hint of shared amusement. They had written their closing remarks separately. They hadn’t spoken once about what they would say.

And yet, when they stood together and delivered their lines — she was cool and crisp, he warm and glib — the words overlapped, echoed, and landed with eerie symmetry. As if they’d rehearsed. As if they already knew each other’s rhythms.

The Great Hall would hear about it by dinner.

But for now, beneath the soft rattle of train wheels and the dimming light through enchanted glass, Harry looked at Daphne’s profile — composed, unreadable, bathed in amber glow — and realized that something had begun.

He didn’t know what it was.

But it felt like fire under ice.
