By the meeting on the Tuesday before the October full moon, Hermione had come prepared with what she was certain was a brilliant plan to put an end to the ongoing Slytherin prefect rebellion over patrol scheduling. She stood at the front of the prefects' meeting room, hands clasped in front of her, radiating a quiet authority that made it clear she wasn't here to negotiate.

The prefects trickled in, some already casting wary glances at the curtain-draped wall behind her. The air was thick with suspicion, particularly from the Slytherins, who were eyeing her with thinly veiled disdain. James leaned casually against the far wall, his hazel eyes dancing with amusement as he observed the scene. He wore a smirk that he was trying very hard—and failing—to suppress. Hermione didn't need to look at him to know he was thoroughly enjoying himself.

Lily, on the other hand, sat near the front, her sharp green eyes darting between Hermione and James with mounting suspicion. She was clearly trying to figure out what was coming, her brow furrowing slightly as she tapped her quill against her parchment.

Hermione let the murmurs and shifting die down before clearing her throat. The room fell silent, all eyes now on her.

"So," she began, her voice calm but firm. "We've had a bit of an issue over the last couple of weeks with sudden 'scheduling conflicts' regarding prefect patrols." Her gaze swept over the group, landing briefly on the cluster of Slytherins at the back, who were looking decidedly unimpressed. "To avoid further incidents where the Head Students are left scrambling at the last minute to find replacements, I've created this scheduling board."

With a flick of her wand, the curtain drew back, revealing a large blackboard mounted on the wall. But this wasn't any ordinary blackboard. It displayed the next four weeks of patrol schedules, neatly organised with each prefect's name engraved on a small, coloured slab of wood. The colours corresponded to their houses, and the precision of the board spoke to hours of meticulous work.

A ripple of murmurs ran through the room, and several prefects leaned forward for a better look. Hermione pressed on before the grumbling could start.

"The rule from now on," she said crisply, "is that anyone who wants to exchange their patrol shift will need to find their own replacement. Both parties must come here and physically switch their slabs on the board. The slabs are charmed so that only their owner can move them, so no one will be able to rearrange shifts behind someone else's back."

She paused, letting the information sink in. "Additionally, the board remembers the last slab in each slot. If you remove your slab without having another to replace it, leaving the shift uncovered, I'll know." Her eyes flicked briefly to the Slytherins again, catching one or two of them narrowing their eyes. "If this happens more than three times without adequate justification—such as a note from Madam Pomfrey in the case of illness—the matter will be brought to the Headmaster, and prefect privileges may be revoked."

The room buzzed with uneasy whispers now. Hermione could practically see the Slytherins calculating how they might exploit the system. She didn't give them the chance to dwell on it.

"I should also mention," she continued smoothly, "that this board is linked to five others—one in each Head of House's office and one in the Hospital Wing. The staff have all agreed to report any suspiciously frequent excuse note requests around the scheduled patrol times directly to the Headmaster."

That earned her a few incredulous looks, and more than one Slytherin let out an audible grumble. James was biting the inside of his cheek, clearly trying not to laugh. Lily, meanwhile, had raised an eyebrow, her gaze now tinged with admiration.

"Before you panic," Hermione said, her tone softening slightly, "I should inform you that this board currently takes into account all known prior engagements—class schedules, Quidditch practices, matches, and so on. It's also well-balanced, meaning the load is distributed equally among all prefects on average. The board will even track any imbalances over time, so if someone starts picking up significantly more or less shifts than others, we'll reassess during our weekly meetings."

She stepped back, her gaze steady as she looked out over the room. "Any questions?"

For a moment, there was only silence, punctuated by a few disgruntled mutters from the Slytherin section. One of them, a wiry boy named Nott, raised his hand lazily, a smirk playing on his lips. "And what happens if someone just... refuses to swap? You can't make us trade shifts."

Hermione tilted her head, her smile cool and calculated. "No, I can't. But I trust your fellow prefects will have little patience for that kind of behaviour when it becomes clear you're leaving them to cover for you, without picking up other shifts in return. And if it happens repeatedly, the Headmaster will hear about it."

She then pointed to the table beside the calendar like shift schedule.

"As I said, the board tracks averages over time. It will become apparent. I'm sure none of you want to risk your position—or your house's standing."

There was a beat of silence before Lily spoke up, her tone impressed but curious. "You really thought of everything, didn't you?"

"I tried," Hermione replied, her lips twitching with a hint of a smile. "This is a team effort. I just want to make sure we're all treated fairly—and that we're all held accountable."

James finally let out a low whistle, his proud grin no longer concealed. "You're brilliant, you know that?"

Hermione gave him a side glance, trying not to let the compliment fluster her in front of the others. "Thank you, James."

The meeting wrapped up shortly after, with more than a few prefects—mainly just Slytherins—shooting Hermione grudging looks as they left. When the last one had gone, James sidled up to her, hands in his pockets, and grinned.

"That," he said, "was a work of art. You've got the Slytherins fuming."

Hermione let out a tired sigh but couldn't help smiling. "Let's just hope it works."

"Oh, it will," James replied confidently. "Especially with you watching like a hawk. Remind me never to get on your bad side, by the way."

She laughed softly, shaking her head. "Just don't skip your patrols, dear soon-to-be husband of mine."

"Wouldn't dream of it," he said, slinging an arm around her shoulders.

Just as they were about to leave, the door to the meeting room opened again, and Remus stepped in, looking slightly frazzled. His usually sharp features were dulled with exhaustion, the full moon only two days away. He rubbed the back of his neck absently, closing the door behind him with a distracted air, as though something important had just occurred to him.

"Hermione," he said, his tone hesitant. "You mentioned the current schedule takes into account all prior engagements? Does that include—?"

Hermione turned to him with a smile, her expression softening instantly. She stepped forward and hugged him, her arms squeezing gently as if to anchor him against the visible weariness in his eyes. "Of course it does," she said, her voice filled with quiet warmth.

Remus blinked, startled but clearly grateful for the embrace. "I mean, I know you're thorough, but… I didn't think you'd take everything into account."

"I remember," Hermione replied simply, stepping back and gesturing toward the board. Her tone was firm but kind, as though she had anticipated this very moment. "Last year, you told me how difficult it was to get shifts exchanged around the full moon. I know how hard it is for you, Remus, and I wasn't about to make you go through that again."

She pointed to the board, where two full moons were marked with subtle silver outlines. Remus's name wasn't listed anywhere near them, not in the days leading up to or following the transformations. "You'll notice," Hermione said, her smile growing, "you're not on patrol anywhere near the full moon. It's scheduled that way on purpose. You don't even have to ask."

Remus stepped closer, his tired eyes scanning the board. It was exactly as she'd said, the thoughtful planning unmistakable. His throat bobbed slightly, and he gave her a small, wry smile. "You… really thought of everything, didn't you?"

"I tried," Hermione said with a small shrug. "You've got enough to handle as it is. Scheduling should be the last thing on your mind." Her voice softened as she added, "You don't always have to carry the burden alone, Remus. I've got your back."

James, who had been quietly watching the exchange, couldn't hide his grin. "See, Moony? She's your best friend for a reason. If I'd made the schedule, I'd have forgotten, but then just banned you from patrol altogether and made Sirius do your shifts. Imagine your patrol buddy's surprise when he showed up."

Remus let out a tired chuckle, but his eyes were warm as he turned back to Hermione. "Thank you," he said earnestly. "It's not just about the shifts—it's… knowing I don't have to fight for it. That someone's already thought about it."

Hermione smiled, reaching out to squeeze his arm gently. "You don't have to thank me for that, Remus. It's just what best friends do."

For a moment, they stood in companionable silence, a quiet understanding passing between them. Then, with a small nod, Remus took a step back toward the door, the tension in his shoulders noticeably eased. "Alright," he said, his lips twitching with the faintest hint of a smile. "I'll leave you two to... whatever you were doing before I interrupted."

"Remus!" Hermione exclaimed, swatting at him indignantly, her cheeks tinged pink. "What are you insinuating? We're in the prefects' office, not our dorm!"

Remus raised his hands in mock surrender, the corner of his mouth twitching into a wider grin. "I'm just saying, it's awfully quiet in here for a planning meeting."

James snorted, clearly enjoying the exchange as he leaned casually against the wall. "See, this is why I like Moony. He knows how to make an exit."

"Don't encourage him!" Hermione shot back, her eyes narrowing as she turned to James. But despite her indignation, the amused glint in her eyes betrayed her. She then turned to Remus again. "Sirius has rubbed off on you, and not in a good way!"

Remus chuckled, already halfway out the door. "Good night, you two," he said lightly, his tone still tinged with mischief as he slipped out and shut the door behind him.

Hermione huffed, crossing her arms as she turned to James, who was grinning at her like the cat that got the cream. "Honestly, you're as bad as he is."

James pushed off the wall, sauntering over with an infuriatingly smug expression. "Maybe," he said, wrapping an arm around her waist and pulling her close. "But you love us anyway."

Hermione rolled her eyes but didn't pull away. "You're lucky that's true, James. Very lucky."

The October 26th full moon cast an eerie silver light over the Forbidden Forest, illuminating the tense group of Animagi and their werewolf friend. Prongs galloped through the dense underbrush, his powerful strides thundering against the forest floor. Padfoot darted beside him, his black fur blending into the shadows, while Wormtail scurried ahead, his small form slipping easily between roots and bushes. Hermione, as an ermine, darted nimbly through the thicket, her sharp eyes watching every movement. At the front of the group, Moony prowled erratically, his growls low and guttural.

It had been an unusually tense night. Moony, restless and agitated, had suddenly veered off in the direction of Hogsmeade, his growls low and dangerous. Prongs had immediately taken off after him, antlers flashing in the moonlight as he tried to intercept their friend. Padfoot wasn't far behind, barking urgently as he closed the gap between them.

In his haste, Prongs misjudged the dense thicket ahead. His antlers snagged on a low-hanging branch, jerking his head back with a sharp crack. A pained bellow escaped him as he struggled to free himself, his large form thrashing in frustration. Padfoot skidded to a halt, his sharp bark cutting through the chaos. He turned back toward Prongs but quickly assessed the greater threat—Moony was nearing the edge of the forest.

With a burst of speed, Padfoot lunged toward Moony, cutting him off before he could reach the outskirts of the trees. The werewolf reared back, snapping and growling, but Padfoot held his ground, herding Moony back toward the group with low, warning barks.

Wormtail darted back to Prongs, his small paws skittering nervously as he squeaked in panic, circling his friend as though trying to figure out how to help. Kitten, quick and nimble, darted up to Prongs's side, climbing onto him in her Animagus form. Her small white form balanced precariously on his broad back as she reached for the branches trapping his antlers. She tugged with all her might, but she was far too small to make any real impact on the tangled wood.

Prongs gave a final, forceful tug, his powerful neck muscles straining as the branches finally gave way with a sharp crack. He stumbled forward, almost unbalancing Kitten, but she leapt gracefully to the ground just in time. Prongs regained his footing, his movements slower now, his head and neck radiating with pain as he limped after Moony, who Padfoot had successfully redirected toward the safety of the Shrieking Shack.

By the time the group reached the Shack at dawn, the tension had worn them all thin. The first rays of sunlight filtered through the broken windows, casting long shadows across the creaking floorboards. One by one, the Animagi transformed back into themselves, their exhaustion evident in the heavy silence. Prongs transformed amongst last, his human form slumping against the wall. James's face was pale, and his movements stiff as he rolled his shoulders gingerly, wincing at the pain.

Hermione, still in her ermine form, darted over to him with a small, chirping squeak before transforming back into herself in one smooth motion. Her hair was windswept, and her expression was a mixture of worry and determination as she knelt beside him.

"James," she said sharply, her voice breaking through the quiet. "Are you alright?"

James let out a weak chuckle, though his grimace betrayed him. "Yeah, I'm fine. Just sore. Those bloody branches had it in for me."

Hermione's eyes narrowed as she reached out to touch his shoulder. He flinched, and she pulled back immediately, her frown deepening. "This doesn't look like nothing," she said, her tone firm. "Let me see."

Reluctantly, James shrugged off his jacket, revealing a nasty bruise spreading across his neck and shoulders. Hermione inhaled sharply. "James! You should've said something sooner."

"It's just a bit sore," he said dismissively, though his clenched jaw told another story. "Really, I'll be fine."

Ignoring his protests, Hermione rummaged through her bag, pulling out a jar of salve and a small phial of pain-relief potion. "Sit still," she ordered, her voice brooking no argument. Carefully, she dabbed the salve onto the bruised area, her touch as gentle as possible. "This should help with the bruising, but you need to go to the Hospital Wing. Madam Pomfrey will be able to treat this properly."

James stiffened at her words. "That's not necessary," he said quickly. "You've already sorted me out."

Hermione gave him a sharp look. "James, this kind of injury could easily be passed off as something that happened at Quidditch practice. There's no reason not to get it treated."

James hesitated, his mind racing. He knew she was right—Pomfrey could fix him up in no time. But if he went to the Hospital Wing, there was no way she'd let him play in the Quidditch match on the 29th. Gryffindor was counting on him as captain and Chaser, and he wasn't about to let them down.

"I'll go in the afternoon," he lied smoothly, giving her a disarming smile. "It's too early in the morning to claim practice and it looks too fresh for it be from yesterday afternoon, and I'll be fine for now."

Hermione frowned but didn't press the issue further. "Alright," she said, though her tone carried a note of warning. "But if it gets worse, promise me you'll go."

"Promise," James said, leaning forward to kiss her forehead, trying to deflect her concern.

Two days later, the Quidditch pitch was alive with the roars of the crowd as Gryffindor and Slytherin faced off in their first match of the season. The tension was palpable, the rivalry between the houses driving both teams to push harder than ever. The stands were a sea of red, gold, green, and silver, with students chanting and waving banners in the crisp autumn air.

James mounted his broom with his usual confidence, joking with his teammates as they prepared for kickoff. But Hermione, watching from the stands, wasn't fooled. She noticed the slight stiffness in his movements, the way he rolled his neck with a wince when he thought no one was looking. Her stomach twisted with unease. He had seemed fine in the past few days, but now she wasn't so sure.

Madam Hooch's whistle pierced the air, and the game began. The Quaffle soared into the sky, immediately grabbed by Slytherin's lead Chaser, who sped toward Gryffindor's goalposts with ruthless determination. The Gryffindor Beaters launched a counterattack with precision Bludger hits, forcing Slytherin to pass back and regroup.

James flew into action, darting to intercept the Quaffle. He managed to snag it mid-air, weaving through the opposition with his usual skill, but his movements lacked their usual ease. Hermione noticed he avoided his typical sharp dives and risky passes, opting instead for safer, slower plays.

Beside her, Lily frowned, her sharp green eyes following James. "What's up with him?" she muttered. "He's holding back. That's not like James."

Hermione bit her lip, her worry growing as she watched him execute a shaky pass to Marlene. Though the Gryffindor Chasers managed to keep the Quaffle moving, their plays weren't enough to overpower Slytherin's aggressive defence. The score stayed painfully close, with Slytherin pulling ahead every time Gryffindor managed to equalise.

Meanwhile, the Seekers darted above the action like hawks, their eyes scanning for the Snitch. Gryffindor's Seeker, a wiry fourth-year named Will Fenwick, hovered near the centre of the pitch, keeping a sharp eye on Slytherin's Seeker, who was shadowing him closely. The tension in the crowd rose with every missed opportunity, and the longer the match dragged on, the more Hermione's worry deepened.

Midway through the game, Slytherin pulled ahead with a spectacular goal, their Chasers working in perfect sync to outmanoeuvre the Gryffindor Keeper. James gritted his teeth and pushed harder, ignoring the strain in his shoulders as he intercepted a risky pass. He darted down the pitch, the Quaffle tucked securely under his arm, but Hermione could see the wince that crossed his face as he turned sharply to avoid a Bludger. His pass to Marlene was clean, but it wasn't enough to stop Slytherin from maintaining their lead.

As the game wore on, it became clear that Gryffindor's Chasers couldn't close the gap on their own. The outcome of the match rested entirely on the Seekers.

The Snitch finally made its appearance, a glint of gold darting near the Slytherin goalposts. Both Seekers spotted it at the same time, diving at breakneck speed. The crowd erupted into chaos, the chants and cheers blending into a deafening roar. Fenwick was fast, but Slytherin's Seeker was gaining on him, his hand outstretched and mere inches away from the Snitch.

At the last possible moment, Fenwick feinted left, throwing off his opponent just long enough to surge forward and close his fingers around the tiny golden ball. The Gryffindor stands exploded in cheers as Madam Hooch's whistle signalled the end of the match.

Hermione let out a shaky breath of relief, but her eyes immediately sought James. He landed alongside his teammates, his grin bright as he clapped Fenwick on the back, but the moment he turned away, Hermione caught the way his hand moved to his shoulder, rubbing it gingerly. Her heart sank. He hadn't gone to the Hospital Wing.

The Gryffindor common room was bursting with energy as the team celebrated their victory. Butterbeer and snacks were passed around, and the air was filled with laughter and cheers. James was at the centre of it all, his grin wide as he recounted the game's highlights to an eager audience with Will at his side.

Hermione waited patiently, biding her time until the crowd thinned enough for her to pull James aside near the fireplace.

"James Potter," she said sharply, crossing her arms.

James turned, his grin faltering when he saw her expression. "Uh, hey, love. Great match, huh?"

"Don't 'great match' me," Hermione snapped, stepping closer. "You didn't go to the Hospital Wing, did you?"

James froze, guilt flashing across his face. "I—uh—"

"James," she interrupted, her tone laced with both worry and exasperation. "You played through an injury? After I specifically told you to get it treated?"

James sighed, running a hand through his hair. "I couldn't risk Pomfrey benching me for the match. The team needed me, Hermione."

Hermione's eyes flashed with frustration. "And what about you? What happens if you make it worse and can't play the rest of the season—or worse, hurt yourself permanently? You're not invincible, James."

"I'm sorry," he said, his voice softening as he reached for her hand. "I'll go now. I promise."

"You'd better," Hermione said, her voice firm but tinged with worry. "Because if you pull something like this again, I'll drag you to the Hospital Wing myself, and I won't care if you scream and kick the whole way."

James chuckled, giving her hand a gentle squeeze. "Deal. But just so you know, if I ever do get benched, I'm blaming you."

"You'd deserve it," Hermione replied, though her glare softened into a small smile. "And I'll still love you anyway. Lucky for you."

"Very lucky," James said, leaning in to press a quick kiss to her forehead. "Thanks, Kitten."

"Go," she said, pushing him toward the portrait hole. "Before I change my mind and drag you by the ear anyway."

James flashed her a grin before slipping out. Hermione watched him go, shaking her head. "Quidditch players," she muttered, turning back to the party with a sigh.

The Gryffindor common room was still buzzing with energy as the party continued, the chatter and laughter filling every corner. The team and their housemates celebrated the hard-fought win, the dramatic capture of the Snitch being retold over and over. Hermione, though, wasn't fully present. Her eyes kept flickering to the portrait hole, her mind elsewhere.

James's absence was beginning to draw attention. Marlene had been the first to ask, her brow furrowed. "Where's our fearless captain? You'd think he'd be soaking up all the praise."

Hermione forced a smile, thinking quickly. "He mentioned something about getting more butterbeer. You know, from that stash the Marauders keep hidden... somewhere."

Marlene's face cleared. "Ah, of course. Trust Potter to stockpile for an emergency." She returned to the conversation, and the excuse seemed to satisfy everyone else—everyone except Sirius, Remus, and Peter, who exchanged knowing glances from their spots near the fire. They'd been there on the night of the full moon and knew exactly why James wasn't around.

As the party began to wind down, the Marauders made their way to Hermione, who was now sitting in one of the oversized armchairs by the hearth, looking more anxious by the minute. Sirius dropped into the seat beside her, draping an arm lazily over the back.

"He'll be fine, Kitten," Sirius said, his voice light but reassuring. "Probably just milking Pomfrey's attention for all it's worth. You know Prongs—any chance to charm her into sneaking him extra chocolate."

Hermione huffed, giving him a half-hearted glare. "That's not helping, Sirius."

"Worth a try," he said, smirking, though the softness in his eyes showed he was just trying to ease her worry.

Remus, sitting across from them, ran a hand through his hair, his expression troubled. "This is my fault," he said quietly. "If it weren't for—"

"Don't," Hermione cut him off, her tone firm but not unkind. "This isn't your fault, Remus. Moony had nothing to do with James being stubborn and reckless. This is entirely on him."

Peter nodded quickly. "Yeah, Moony didn't make him ignore an obvious injury. That was all James."

Remus looked unconvinced, but he didn't argue further. Instead, he sat back with a resigned sigh, his gaze distant.

Hermione, who had been glancing at the clock every few minutes, finally stood. "I'm going to check on him in the Hospital Wing."

But just as she was about to head to the portrait hole, the door swung open, and James stepped inside, his expression unusually subdued.

"What's the verdict?" she asked, crossing her arms, her voice tinged with worry despite her attempt to sound casual.

James gave a long sigh, running a hand through his hair. "No practice for the next two weeks. Pomfrey gave me some specialized salves to help the muscles heal." His tone was bummed, his usual confidence replaced with a quiet frustration. "She said I was lucky it wasn't worse."

"Two weeks isn't bad," Sirius chimed in, trying to lighten the mood. "You'll have more time to perfect that smoulder you give McGonagall when she's about to scold you."

James shot him a look but didn't respond, his gaze flicking to Hermione.

"Given that your next match isn't until February, I think you can live," Hermione said, her voice firm but not unkind. She stepped closer, her arms unfolding as she placed a hand on his arm. "And maybe next time you'll listen when someone tells you to get treated right away."

James gave her a sheepish smile. "Yeah, lesson learned."

"Good," Hermione said, her stern tone belied by the small smile tugging at her lips. "Now, sit down before you do something stupid like re-injure yourself."

James let out a laugh, his shoulders relaxing as he allowed her to steer him toward the couch. Sirius leaned back, grinning. "See? She's got you sorted. You're in good hands, Prongs."

"Better than Pomfrey's?" James teased, throwing Hermione a cheeky look.

"Don't push it," she shot back, though the warmth in her voice was unmistakable. The group settled into a more relaxed atmosphere, the earlier tension easing as they spent the rest of the evening together, James's injury now firmly under Hermione's watchful eye.

The night of the Halloween feast was filled with the warm, golden glow of floating jack-o'-lanterns, the enticing aroma of roasted meats, and the chatter of excited students. The Great Hall was decked out in its usual festive splendour, with bats swooping above the enchanted ceiling and a spectacular display of sweets and pastries at every table.

James sat with his friends at the Gryffindor table, absently rubbing his still-sore shoulder. Though the pain had diminished significantly since the Quidditch match, the lingering stiffness was a constant reminder of Madam Pomfrey's strict orders: no practice for two weeks. He'd counted the days—one and a half weeks to go.

"You alright there, mate?" Sirius asked, eyeing him as he absently stabbed at a pumpkin tart with his fork.

James huffed, tossing the fork down. "Fine. Just going mad with this no-practice rule. I'm losing my edge sitting around doing nothing."

Remus smirked, taking a sip of his pumpkin juice. "You're not sitting around doing nothing, James. You've been pacing like a caged animal, annoying the life out of all of us."

"Too right," Peter piped up, grinning. "Yesterday, he spent an hour convincing me we should take up duelling practice, just to keep his reflexes sharp."

"Exactly!" James said, throwing up his hands. "How does Pomfrey expect me to stay in top form if I'm banned from doing anything remotely physical?"

Hermione, seated across from him, rolled her eyes. "She expects you to heal so you don't hurt yourself worse, James. That's the point."

James shot her a look, then grinned mischievously, the familiar glint of trouble lighting up his hazel eyes. "Well, if I can't play Quidditch, I might as well put my talents to other uses."

"Oh no," Hermione muttered, already regretting whatever he was about to suggest.

Sirius perked up instantly. "Oh yes. What's the plan, Prongs?"

James leaned in, lowering his voice conspiratorially. "See those bats?" He nodded toward the clusters of enchanted bats flitting around the ceiling. "I may or may not have charmed a couple to dive-bomb specific targets. Imagine—Slytherins covered in pumpkin guts."

Peter snickered. "Brilliant."

Hermione groaned. "James, you're impossible. This isn't going to end well."

"Relax, Kitten," James said, flashing her a grin as he pulled his wand from his pocket. "It's just a harmless prank."

Before Hermione could protest further, James muttered a quick incantation under his breath, aiming his wand subtly at the ceiling. A pair of bats veered off their flight path, swooping down toward the Slytherin table with alarming speed. One collided with a particularly large pumpkin on the end of the table, sending orange pulp and seeds flying everywhere. The second bat narrowly missed, causing a cascade of juice to splash over the robes of a very irritated-looking Snape.

The Gryffindor table erupted into laughter, with Sirius howling loudest of all. Even Remus was grinning despite himself, while Peter looked as though Christmas had come early.

"See?" James said, smirking triumphantly. "Perfectly executed."

But as he stood to take a mock bow, the motion sent a sharp jolt through his shoulder. He winced, clutching at it as he sat back down hurriedly.

"Instant karma," Hermione said dryly, raising an eyebrow as she passed him a napkin for the beads of sweat forming on his forehead. "You deserve it."

"Shut it," James muttered, massaging his shoulder gingerly. "It's just a little twinge."

"More than a twinge if you're making that face," Hermione retorted, her tone somewhere between exasperation and amusement. "You're lucky Pomfrey didn't see that. You'd never hear the end of it."

At the Slytherin table, chaos was unfolding as several students tried to clean themselves up, Snape glaring daggers across the room. Dumbledore raised his glass in apparent toast to no one in particular, his twinkling eyes betraying his amusement at the display.

"Worth it," James said finally, grinning despite the pain.

Hermione shook her head, unable to suppress a small smile. "You're impossible."

"And you love me for it," James replied cheekily, wincing again as he tried to move his shoulder. "Now, can I get a bit of sympathy here, Kitten?"

Hermione sighed, grabbing her wand to set a warming charm on his shoulder that helped the muscles relax. "Hold still, you idiot. But if you pull something like this again, I'm leaving you to Snape's mercy."

Sirius leaned over, clapping James on the good shoulder. "Totally worth it, mate. 10 out of 10 for execution. 5 out of 10 for follow-through."

Remus chuckled. "Next time, try a post-prank gloat that doesn't involve you aggravating your injury. You've got enough people keeping an eye on you as it is."

"Noted," James said, though the glint in his eyes suggested he'd learned absolutely nothing.

Sirius leaned casually against the doorframe of the Head Students' dormitory, his usual swagger tempered with a rare note of sincerity. It was the evening of November 3rd, his 18th birthday, and for once, he didn't seem interested in a grand celebration or one of his usual larger-than-life pranks. Instead, he had made an uncharacteristic request: a quiet party with just the Marauders, Hermione, and—fine, Lily, if she insisted.

James was already grinning like a Cheshire cat as he helped Hermione set up the small but cosy space. "Can't believe it, Pads. The great Sirius Black, requesting a low-key birthday party. Is this a prank? Are we going to find dungbombs hidden under the cushions?"

Sirius rolled his eyes, flopping dramatically onto one of the armchairs. "Relax, Prongs. I'm turning 18, not losing my touch. Sometimes even I appreciate a bit of peace and quiet."

"Uh-huh," Hermione said, arching an eyebrow as she adjusted the enchanted candles floating above the room. "You just want to find out the password to our dorm again, don't you?"

Sirius smirked, sitting up straighter and giving her a mock-wounded look. "Hermione, I'm offended. Can't a man celebrate his birthday in the company of his closest friends without being accused of ulterior motives?"

"Not when that man is Sirius Black," Hermione retorted, her arms crossed as she shot him a knowing look.

"Kitten," Sirius said, placing a hand dramatically over his heart. "I'm hurt. Truly. But now that you mention it…" His smirk widened, and his grey eyes glinted with mischief. "Wouldn't it be convenient if I happened to pick up the password during the festivities?"

James groaned, tossing a throw pillow at him. "Sirius, if you 'accidentally' overhear the password again, Hermione will kill me first. And then you."

"Not if she kills him first," Remus chimed in, entering the room with a tray of butterbeers. He gave Sirius a pointed look. "You know she'll spot you trying before you even get close."

Hermione grinned triumphantly. "Exactly. So don't even think about it."

Sirius shrugged, grinning unabashedly. "Fine, fine. No password-stealing. I solemnly swear." But as his friends rolled their eyes, his grin widened, and he added under his breath, "For now."

The evening unfolded with surprising ease. James and Peter had smuggled in a small cake, charmed to erupt with harmless fireworks when the candles were blown out. Lily—who had begrudgingly accepted the invitation—brought a bottle of pumpkin fizz, which Sirius declared "barely passable" until she threatened to hex him.

The group exchanged stories, laughed until their sides hurt, and, for a while, Sirius allowed himself to let go of the weight that so often pressed on his shoulders.

As the night wore on, Hermione watched Sirius from her spot on the couch. For all his teasing and bravado, there was something softer in his eyes tonight—a quiet contentment that she didn't often see. Maybe, just this once, his request for a quiet celebration had been genuine after all.

Still, as Sirius leaned back with a satisfied sigh, James smirked. "So, Pads, what's the real reason for this cosy little party? Come on, you can tell us."

Sirius grinned lazily, raising his butterbeer in mock toast. "If I told you, it wouldn't be a secret, would it?"

"Secret or not," Hermione interjected, her tone playful but firm, "I'll know if you're up to something."

"Kitten, you've got me all wrong," Sirius said with an exaggerated sigh. "I'm the picture of innocence."

Hermione snorted. "Sure you are. Happy birthday, Sirius."

He winked at her. "Thanks, Kitten. You're my favourite… even if you do make it impossible to have a bit of fun."

As laughter filled the room, Sirius raised his bottle again, his smirk softening into something more genuine. For one night, surrounded by his friends, he didn't need anything else. Even if he did still plan to eavesdrop on that password eventually.

The next morning, Hermione groggily shuffled toward the bathroom she and James shared in the Head Students' dorm, still half-asleep as she reached for the doorknob. The party the night before had been unexpectedly quiet—a suspiciously uncharacteristic choice for Sirius Black—but Hermione had chalked it up to his rare moment of wanting something low-key.

She stepped inside, yawning, only for a loud pop to echo through the room. Before she could react, a torrent of cold, glittering water drenched her from head to toe. Hermione froze, blinking in shock as she processed what had just happened. The water had soaked her completely, her white uniform shirt clinging to her like a second skin.

"SIRIUS BLACK!" she yelled, her voice echoing off the bathroom walls.

Her shout must have carried through the dorm because, moments later, the door on the right burst open, and James rushed in, wand in hand. "Hermione, what—" His words faltered as he stopped dead, taking in the sight before him.

Hermione turned sharply, her cheeks immediately flaming as she realised how she must look. Her soaked-through shirt left absolutely nothing to the imagination. She crossed her arms over her chest, glaring at him. "James Potter, get out!"

But instead of leaving, James stood there, his expression flickering between concern and poorly concealed amusement. A grin tugged at the corners of his mouth. "Oh no, don't tell me—was this Sirius?"

"Of course it was Sirius!" Hermione snapped, her embarrassment outweighing her frustration. "Who else would—oh, stop laughing!"

James had failed spectacularly at keeping his laughter in check, and now he was doubled over, clutching his stomach. "I—I'm sorry," he managed between gasps. "It's just—Merlin's pants, Hermione, this is peak Sirius. He's outdone himself."

"James," she warned, though her face burned hotter when his gaze flickered back to her. "Stop staring and give me a towel before I hex you!"

James straightened up, his cheeks red from laughter as he grabbed a towel off the rack and handed it to her. "Alright, alright. Here. But you've got to admit, this is a classic. It could've been me, you know. Just bad luck you were the first one in here this morning."

Hermione snatched the towel, wrapping it around herself as she tried to glare at him through her mortification. "Why didn't it trigger last night when we did our evening routine?"

James's grin widened. "Because Sirius is sneaky. He probably set it to go off after a certain time—long enough to make sure we wouldn't expect it."

Hermione groaned, rubbing her temple as she muttered, "I should've known the quiet party was a setup. I didn't think he'd stoop this low."

"Stooping is Sirius's speciality," James said cheerfully, leaning casually against the doorframe. "But hey, at least it wasn't something worse, like turning the water into mud. Or spiders."

Hermione shot him a glare. "You're not helping."

"Sorry, sorry," James said, though the grin on his face betrayed his lack of sincerity. "For what it's worth, I think he might've been planning for it to hit me. You just got here first."

"Well, he's going to regret that," Hermione muttered, dabbing at her hair with the towel. "Because if he thinks he can get away with this, he's sorely mistaken."

James chuckled, stepping closer. "Need help plotting your revenge?"

She raised an eyebrow, her lips twitching despite herself. "Oh, I don't need help. But thanks for the offer."

"Fair enough," James said with a shrug, though his eyes gleamed with mischief. "Just make it good. Sirius deserves it after this."

"Oh, don't worry," Hermione said, her tone dark with mock menace as she began wringing out her hair. "He won't know what hit him."

James's grin softened as he reached out to tuck a wet strand of her hair behind her ear. "For what it's worth, you look good even when you're drenched."

Hermione huffed, shoving his good shoulder lightly, though her cheeks were still red. "You're lucky I'm too distracted to hex you right now."

James laughed, retreating to give her space. "Alright, I'll go make sure Sirius is still alive when you're ready to deliver your wrath."

"Good idea," Hermione said, waving him off as she began to dry herself properly. "Because he won't be when I'm done with him."

As James left the bathroom, his laughter echoed faintly behind him. Hermione smirked to herself. Sirius had started this war, but she was going to finish it.

Hermione decided revenge was best served cold. After getting changed into dry clothes and taming her dripping hair, she emerged from the bathroom with a perfectly composed expression, betraying none of the frustration or embarrassment she had felt earlier. If Sirius Black thought he'd gotten away with his prank, he had another thing coming—but for now, she would let him bask in his false sense of victory.

She found him lounging in the Gryffindor common room, his feet propped up on a low table, tossing a Gobstone lazily in the air. A smug grin tugged at the corners of his mouth as he glanced at her. Clearly, he was waiting for her to say something about the morning's "excitement."

But Hermione didn't give him the satisfaction. She swept past him, offering a perfectly neutral, "Good morning," as though nothing out of the ordinary had happened.

Sirius blinked, momentarily thrown off, but quickly recovered. "Morning, Kitten," he said, his tone loaded with playful curiosity. "Sleep well?"

"Quite," Hermione replied smoothly, not even glancing his way as she joined James by the portrait hole. "We've got a busy day ahead. Let's not waste time."

James, who had been tying his shoelaces, caught the glint of mischief in her eyes as she looked at him. A slow grin spread across his face. He straightened up, falling into step beside her. "Right. Busy day. Let's go."

Sirius frowned as the portrait swung shut behind Hermione and James, the Gobstone tumbling into his lap. Something about Hermione's composed exit didn't sit right with him. He'd been bracing for a scathing tirade, or at the very least a hex to the head, but she had given him nothing. It was unnerving, especially coming from Hermione, who he knew wasn't one to let things slide.

As he leaned back in his chair, tossing the Gobstone into the air again, a nagging sense of déjà vu crept over him. It tugged at the edges of his memory, taking him back to their fourth year—Hermione's first year at Hogwarts.

Sirius had taken it upon himself to "welcome" the new, previously homeschooled Gryffindor with what he considered a classic Sirius Black initiation: an elaborate series of slime and glitter pranks. She'd been the perfect target, always so poised and proper, and he'd been certain she'd crack under the chaos. But to his surprise—and his growing frustration—Hermione hadn't reacted at all. She'd calmly cleaned herself up, smiled sweetly at him, and carried on as though nothing had happened.

It had driven him mad.

Back then, he'd spent weeks trying to one-up himself, each prank more elaborate than the last, only for Hermione to brush them off without so much as a raised eyebrow.

And now, three years later, here he was again.

"She's doing it again," Sirius muttered to himself, scowling at the memory. The Gobstone slipped from his hand, clattering onto the table. He picked it up absently, his mind racing. She hadn't even flinched at the prank this morning. No yell, no angry glare, no muttered threats about revenge.

Which could only mean one thing: revenge was already in the works. She wasn't the new girl anymore, she was a Marauder through and through.

A slow grin spread across Sirius's face. "Alright, Kitten," he murmured, his grey eyes glinting with amusement. "Game on."

Still, a faint unease lingered in the back of his mind. He remembered all too well how her non-reactions in fourth year had lulled him into a false sense of security before she turned the tables spectacularly that ended in a bet that left him unable to prank anyone for a week. That quiet, calculating look she'd given him this morning—it had the same energy.

For now, though, he'd enjoy the calm before the storm. After all, he was Sirius Black. If she wanted a prank war, he was more than ready. But even as he leaned back with a smug grin, a small voice in the back of his head whispered: You've no idea what you've just unleashed.

The next morning was a Hogsmeade weekend, and Hermione and James were up early coordinating the logistics of student departures. As Head Students, they were stationed by the castle entrance to oversee the process, ensuring that no one forgot their permission slips and that everyone behaved themselves. But as the groups began filtering out, Hermione's opportunity presented itself.

Sirius strolled past with Remus hanging on his arm, his hands in his pockets, chatting animatedly about some plan for visiting Honeydukes. Hermione waited until he was just out of earshot, her wand concealed discreetly in her sleeve, before casting a quick charm. A faint shimmer appeared on the back of Sirius's cloak.

James, standing beside her, let out a quiet snort. "That's brilliant," he murmured, barely able to contain his laughter.

Hermione smirked. "He'll never know what hit him."

The bustling streets of Hogsmeade were alive with chatter and laughter as students wandered between shops, their pockets jingling with coins saved for Butterbeer and sweets. Sirius and Remus strolled leisurely down the main road, Sirius in high spirits as he lamented about ways to get Hermione and James again, since obviously the bathroom prank had been too tame—delivered, naturally, with his signature flair for double entendre.

"I'm telling you, Moony," Sirius said, his grin devilish, "we're overdue for something brilliant. Maybe a new Zonko's special? Or I could enchant James's broom to handle... more weight. You know, for the extra baggage he's carrying these days."

Remus raised an eyebrow, biting back a laugh. "Extra baggage?"

Sirius smirked, gesturing vaguely. "You know—Hermione. With the way she bosses him around."

Remus shook his head, his lips twitching. "You do realise you're going to regret saying that if she hears you?"

Sirius grinned, completely unfazed. "What's life without a bit of danger? Besides, I think Prongs enjoys it—being, you know, handled."

Remus choked on his pumpkin fizz and shot him a look, half-amused and half-exasperated. "You're unbelievable."

Sirius clapped him on the back, his grin widening. "Unbelievable and brilliant. Which is why I'm thinking we need to test just how much Hermione can handle. Maybe I'll prank them both—see if she really can keep him on a leash."

Remus couldn't help muttering under his breath, "She's going to leash you by the time she's done with this."

"Hey, Sirius!" a voice called out, cutting through the crisp autumn air.

Sirius turned, his grin widening instinctively as he spotted a group of third-year Gryffindors loitering outside Tomes and Scrolls. "What's up?" he asked casually.

One of them giggled. "Can you do your dog impression? We heard it's really good!"

Sirius blinked, his smile faltering. "What are you on about?"

"You know," another one said, their grin growing wider. "Your dog impression! Come on, show us!"

Remus, who had been walking beside Sirius, suddenly seemed very interested in adjusting the cuffs of his jumper. He bit his lip, his shoulders shaking ever so slightly. "What's this about a dog impression, Padfoot?" he asked innocently.

"I have no idea," Sirius said, his voice tinged with exasperation. "I don't do dog impressions. Who's been spreading these lies?"

The third-years dissolved into laughter, scampering off before Sirius could demand further answers. He turned to Remus, frowning. "What was that about?"

Remus shrugged, his expression suspiciously neutral. "Beats me."

Brushing it off, Sirius continued down the road, though he couldn't help but notice more giggles and sideways glances being directed his way. It wasn't long before another group approached—this time, a pair of Ravenclaws outside Zonko's.

"Oi, Black!" one of them called out. "Let's hear that bark of yours!"

"What?" Sirius asked, his frown deepening.

"You know, the bark!" the Ravenclaw said, grinning. "Heard it's impressive."

Remus, now trailing a step behind, appeared to be struggling to keep a straight face. Sirius shot him a sharp look. "What is happening today?"

"Maybe they've all lost their minds," Remus offered, his voice suspiciously strained.

Sirius waved the Ravenclaws off, muttering something about Gryffindor pranks getting out of hand. But the encounters didn't stop. At Honeydukes, a pair of Hufflepuff girls approached him, all but begging him to do his "dog trick." Outside the Three Broomsticks, a group of Slytherins sneered as one of them drawled, "Black's circus act must be on tour."

Sirius frowned, his paranoia growing. He glanced around, half expecting James or Peter to jump out from behind a barrel. But no one was there.

By the time they reached the post office, Sirius was visibly agitated. His normally casual saunter had turned into a brisk pace, his jaw tight as he glared at every passing student.

"Alright, Moony," he said finally, stopping in his tracks and spinning to face Remus. "What is going on? Why is everyone asking me to do a dog impression?"

Remus had been suspiciously quiet for most of their walk, but at that, he finally burst out laughing. He doubled over, clutching his stomach as Sirius stared at him, incredulous.

"Moony!" Sirius snapped. "This isn't funny!"

"Oh, it's brilliant," Remus managed, pointing weakly at Sirius's back. "Padfoot, you've been... marked."

"Marked?" Sirius repeated, his voice rising in indignation. "What does that even mean?"

Remus gestured for him to turn around, still struggling to catch his breath. Sirius craned his neck, catching sight of his reflection in the glass window of a nearby shop. His jaw dropped as he read the glowing words on the back of his cloak:

Ask Me to Do My Best Dog Impression.

"SON OF A BITCH!" he roared, causing several passing students to jump in alarm.

Meanwhile, back at the castle, Hermione and James were lounging in the common room, their laughter echoing off the walls. Reports of Sirius's encounters had already started trickling back from students returning early, and each new retelling sent them into fresh peals of laughter. They had decided to stay behind, and enjoy a bit of peace and quiet.

"Did you hear about the Ravenclaws?" James wheezed, clutching his side. "Apparently, one of them asked if he could roll over and play dead!"

Hermione was wiping tears from her eyes, her cheeks aching from how hard she was laughing. "It's perfect," she said, taking a deep breath. "Absolutely perfect. He'll never live this down."

"You've outdone yourself, Kitten," James said, grinning at her. "I don't think I've ever seen Pads this worked up."

"It's what he deserves," Hermione replied primly, though her smirk gave her away. "Let's see how he likes being the butt of the joke for once."

Just then, the portrait door burst open, and Sirius stormed in, his cloak still glowing with the offending words. Remus followed behind him, his expression torn between amusement and sympathy.

"Alright, which one of you did it?" Sirius demanded, his grey eyes blazing as he pointed accusingly at James and Hermione.

"Did what?" James asked innocently, his hazel eyes wide with feigned confusion.

"You know exactly what!" Sirius snapped, whirling to gesture at his back. "This! This... treachery!"

Apparently, he still hadn't been able to cancel the charm.

"Do you have any idea how many people barked at me today?" Sirius exclaimed in outrage.

Hermione, sitting on the couch with her book, barely glanced up. "Really? How odd."

Sirius turned on her, narrowing his eyes. "You. It was you, wasn't it?"

Hermione set the book down calmly, looking up at him with a perfectly composed expression. "Oh, me? Why would I do such a thing?"

"Because you're evil," Sirius shot back, flopping dramatically into a chair. "Someone even asked me if I could fetch!"

James burst out laughing, nearly falling off the couch. "That's amazing."

"Maybe it was karma for soaking your Head Girl yesterday morning," Hermione suggested.

"You," Sirius growled, pointing at Hermione, "are officially my nemesis."

James burst out laughing again, leaning back against the cushions, giving Hermione a quick peck on the cheek. "She got you good, Pads."

Sirius groaned, throwing an arm over his face. "Fine. You win this round, Kitten. But mark my words—this isn't over."

Hermione smirked, picking up her book again as James stood up. "I'm sure it isn't. But next time, maybe think twice before messing with my morning routine," she said.

Sirius muttered something under his breath about revenge, but James clapped him on the shoulder with a grin. "Come on, Pads. Admit it. She's got you beat."

"For now," Sirius grumbled, though the faintest hint of a grin tugged at his lips. "For now."
