The summer before Harry's fourth year at Hogwarts was a whirlwind of excitement, nerves, and—as always—mischief in the Potter-Black household. But this year, the buzz wasn't just about the Triwizard Tournament. No, the bigger event—at least according to the family—was that Danica Potter-Black, their resident broody genius, was finally heading to Hogwarts.

"She’ll be in Slytherin," Regulus said one evening as the family sat around the fireplace. He leaned back in his chair, a book open on his lap. "Mark my words."

Harry, sprawled across the rug with Danny's legs resting on his back, snorted. "Yeah, sure, Baba. You said that about me too, remember?"

Regulus gave an exaggerated sigh. "Yes, well...you're James' child. No cunning bone in your body."

"Hey!" Harry protested as Y/N burst out laughing beside him.

"He's got a point, sweetheart," she teased. "You do tend to wear your heart on your sleeve."

"Unlike Danny here," Harry grumbled, tossing a pillow backward. It hit Danny squarely in the stomach, but she didn’t even flinch. The eleven-year-old had her nose buried in Advanced Magical Theory—a book meant for sixth-years.

"I’m still deciding," Danny said coolly, flipping a page without looking up. "Slytherin or Ravenclaw. They're both fine options."

Harry groaned dramatically. "You're such a little snob."

"And you're predictable," Danny shot back. "Hazzy, you practically begged to be in Gryffindor."

"I did not beg."

"Yes, you did," Regulus said with a smirk.

Y/N laughed harder. "You did, love. It's okay. We still adore you."

Harry dropped his head into his arms, groaning. "This family’s the worst."

Platform 9¾ was, as always, a chaotic mess of trunks, cats, owls, and frantic parents. Harry stood beside Danny, who was watching everything with her usual quiet intensity. She was dressed neatly in a crisp button-up and black jeans, her curls pulled back into a braid that Y/N had wrestled into submission that morning.

"See that kid over there?" Harry leaned toward her, nodding toward a nervous-looking boy holding a toad. "Neville Longbottom. Super nice. If you get lost, find him."

Danny arched an eyebrow. "You mean the boy who melted his own cauldron in first year?"

Harry winced. "He's improved."

Regulus crouched beside his daughter, adjusting the strap on her satchel. "Remember, starshine, you don’t have to decide who you are today. The Hat will know where you belong."

Danny nodded, though her lips pressed into a thin line.

Y/N kissed the top of her head. "And if you get nervous, remember that you know more spells than half the seventh-years."

Danny finally smiled. "Because Baba taught me illegally?"

"Technically, it was more of a loophole," Regulus muttered.

The train whistled, and Harry ruffled Danny's hair. "C’mon, Bug. Time to go."

As Harry led her toward the train, Danny suddenly stopped. She turned and ran back to her parents, wrapping her arms tightly around Regulus first, then Y/N.

"Love you," she whispered.

"We love you too," Y/N said, voice thick.

Regulus hugged her tightly, then cupped her cheek. "Go show them what a Black can do."

Danny gave a sharp nod and marched after Harry.

From the window, Harry waved at his parents as the train pulled away. Beside him, Danny stood on her tiptoes, her eyes already scanning the train for potential threats—or opportunities.

"First-year nerves?" Harry asked.

Danny smirked. "Please. I’ve been ready since I was six."

The Sorting Hat’s mouth opened wide as it sat atop Danica's head.

"Ahhh…interesting. Very interesting indeed. Ambitious…clever…calculating…but also…hmm…you love your family more than anything. Brave for them. Protective."

Danny gripped the edge of the stool. Not Gryffindor. Not Gryffindor.

"Not Gryffindor? Ah. Like your brother…though you wouldn't do terribly there either. You’ve got that same sharp mind your mother has…and your father’s…ah yes…his talent. So…where to put you…?

The entire hall seemed to hold its breath.

"SLYTHERIN!"

The Slytherin table erupted into cheers. Danny slid off the stool, her face calm but her heart racing. As she sat down beside a fourth-year named Gemma Farley, she sneaked a glance at the staff table.

Her mother gave her a wink.

Danny's lips twitched upward. She turned to the table of green and silver and thought, Yeah. This fits.

Meanwhile, Harry groaned across the hall at the Gryffindor table. "Baba’s never gonna let me live this down."

warnings: fluff and a bit of humor

The Black-Potter living room was a study in contrasts. On one side, sprawled across the thick, emerald-green rug, Harry and Y/N lay on their backs, laughing breathlessly after what had been, according to them, an epic tickle war. On the other side of the room, Regulus sat on the couch, legs crossed, one arm draped casually over the backrest. Beside him, their six-year-old daughter, Danica "Danny" Potter-Black, mirrored his posture with unsettling accuracy.

Both father and daughter held books in their hands. Regulus was reading a dense, leather-bound tome about magical theory, his brows furrowed in concentration. Danny, meanwhile, had a picture book titled The Curious Cauldron Chronicles, but it wasn't the pictures she cared about. Her small finger traced the words on the page as she read quietly to herself, lips moving with every sentence.

"She's just like you," Y/N said from the floor, propping herself up on her elbows as she watched the pair. "Quiet, broody, and disturbingly good at everything."

Regulus glanced over the top of his book, a smirk pulling at his lips. "Disturbingly? I'm gifted, not disturbing."

"Baba," Danny said without looking up, "Mama's jealous that we're smarter."

Regulus chuckled. "That must be it."

Y/N gasped dramatically and flopped back onto the rug. "You hear that, Harry? Our broody geniuses think they're better than us."

Harry, sprawled beside her with his messy black hair sticking up in every direction, grinned mischievously. "Yeah, well, they probably can't do this." He scrambled to his feet and launched himself into a spontaneous, lopsided cartwheel.

Danny finally looked up from her book, unimpressed. "That's not hard," she said, setting her book aside and sliding off the couch. She attempted a cartwheel, landing with a heavy thud on her side. She scowled as her curls flopped into her eyes. "Okay," she muttered. "Maybe it is hard."

Y/N laughed and sat up. "It's okay, Danny-bug. We'll teach you."

"I don't need help," Danny mumbled, climbing to her feet and brushing herself off. "I just need practice."

"She's definitely yours," Y/N said, looking pointedly at Regulus.

"And Harry's yours," Regulus countered, tilting his head toward their son, who was now attempting to do jumping jacks while singing a made-up song about dragons.

"I'm like Mama!" Harry declared proudly, flopping down beside her again. "We're the fun ones."

Y/N ruffled his hair. "That's right, Hazzy. We cause the chaos while they sit around reading big boring books."

Danny crossed her arms, standing next to her father with an identical expression of disdain. "Books aren't boring," she huffed.

"Exactly," Regulus said, holding out a hand for a high five. Danny slapped his palm with the practiced precision of someone who'd done it many times before.

"See," Y/N whispered to Harry. "Broody, smart, and way too serious."

Harry giggled, but his eyes softened as he watched his sister sit back down beside their father. "I like it when Danny reads to me sometimes," he said quietly.

"Of course you do," Y/N said, kissing his temple. "She's your little sister. You're supposed to think she's cool sometimes. Just don't tell her that too often."

Harry nodded sagely. "Got it."

Across the room, Danny leaned into Regulus's side, her head resting against his arm as she picked up her book again. He angled the book slightly toward her, pointing out a tricky word when she hesitated.

Y/N smiled softly. "She's going to be just like you, you know."

Regulus glanced up. "Brilliant and devastatingly handsome?"

"I was going to say a stubborn know-it-all, but sure, let's go with that."

Danny, still absorbed in her book, gave a tiny smile at her parents' teasing. Harry, meanwhile, tugged on Y/N's hand. "Come on, Mama! Let's build a pillow fort!"

Y/N jumped to her feet with a conspiratorial grin. "Excellent idea, partner-in-crime."

As the energetic duo began dragging pillows and blankets from every corner of the room, Danny peeked over her book. "That blanket's mine," she said.

"Then come help us," Y/N said with a wink.

Danny hesitated. But when Regulus nudged her lightly, she stood and crossed the room, grabbing a pillow and placing it with calculated precision.

"We're going to have our hands full with these two," Y/N murmured as Regulus joined her on the couch.

Regulus draped an arm around her shoulders, watching Harry enthusiastically demonstrate the "proper" way to build a pillow fort while Danny corrected his measurements. "Yes," he agreed, pressing a kiss to Y/N's temple. "And I wouldn't change a thing."

Outside, the winter wind howled against the windows. Inside, the Black-Potter family remained warm, chaotic, and perfectly complete.

The adventures of Danny and Hazzy

Harry and Danny growing up in the Potter-Black household.

warnings: a lot of fluff, Y/N and Regulus kissing at the end

6 MONTH OLD DANNY AND FOUR-YEAR-OLD HARRY 

The Black-Potter household was filled with soft giggles and the occasional delighted squeal. Six-month-old Danica or Danny as Harry fondly called her, sat propped up with pillows on a blanket spread across the living room floor. Her dark curls were already forming wild ringlets, and her bright gray eyes tracked her big brother's every movement.

"Look, Danny! It's a flying hippogriff!" Harry declared, holding a stuffed hippogriff in the air and zooming it around with exaggerated whooshing noises. He had charmed it to hover slightly, the wings flapping as it circled Danny's head.

Danny blinked, then let out a squeal of laughter, her tiny hands reaching up to grasp at the toy. When the hippogriff dipped low enough, she latched on with surprising strength, pulling it down and gnawing on the soft beak with a satisfied coo.

"You're a natural beast-tamer," Harry said, lying down next to her. He tapped her nose gently. "But you can't eat a hippogriff, Danny. That's rude."

Danny babbled in response, releasing the toy to pat Harry's cheek with a slobbery hand. Harry made a dramatic choking sound. "Ah! Baby drool! My one weakness!"

He flopped backward with a groan, limbs sprawled dramatically. Danny stared at him for a moment, then let out a delighted shriek, her tiny body bouncing with excitement.

From the doorway, Y/N and Regulus watched the scene unfold. Y/N's arms were crossed, a smile softening her face. "I give it three seconds before she crawls after him," she whispered.

"Two," Regulus corrected.

As if on cue, Danny tipped forward, arms wobbling as she pushed herself toward her brother. Her movements were clumsy but determined, her little fists digging into the blanket.

"She's doing it!" Y/N breathed.

"Go, Danny!" Regulus encouraged softly.

Harry peeked through one eye when he heard the rustling. His mouth dropped open. "You're crawling!" he gasped, sitting up. "Go, Danny, go!"

Danny let out a gurgling laugh as she reached Harry's knee and promptly face-planted into his leg. Unbothered, she turned her head to grin up at him, her cheeks flushed with effort.

"You're the best little sister ever," Harry said, scooping her into his arms. He stood and turned toward their parents. "Mama! Baba! Did you see? She crawled!"

"We saw, sweetheart," Y/N said, wiping away a tear with the back of her hand.

Regulus stepped forward and ruffled Harry's hair. "Good job, big brother. Looks like she's trying to keep up with you already."

Danny babbled happily from Harry's arms, then stuck her thumb in her mouth and leaned against his chest, suddenly exhausted from her grand adventure.

"She's gonna be unstoppable," Harry said proudly.

Y/N wrapped an arm around Regulus's waist and smiled. "She already is."

TWO-YEAR-OLD DANNY AND FIVE-YEAR-OLD HARRY

The Black-Potter household was rarely quiet these days, not with a curious, toddling two-year-old exploring every corner and a protective big brother trailing after her like a miniature sentry.

"Hazzy!" Danny's delighted voice rang through the sitting room as she toddled across the rug on unsteady legs. Her chubby arms were outstretched toward her brother, who knelt with his arms wide open.

"That's me!" Harry said with a grin, scooping her up and twirling her around. "Hazzy is here to save the day!"

Danny squealed with laughter, her dark curls bouncing with each spin. "Hazzy! Hazzy!"

From the armchair, Y/N smiled over her cup of tea. "Still not calling you Harry, huh?"

"Nope," Harry said, plopping down on the couch with Danny nestled against him. "I've tried to teach her, but she just keeps saying 'Hazzy.'"

"It's cute," Y/N said softly, watching as Danny poked at the buttons on Harry's sweater.

The sound of the front door opening interrupted their moment. Danny's eyes lit up, and she scrambled out of Harry's lap, nearly tripping over her own feet.

"Baba!" she cried, sprinting toward the hallway.

"Danny!" Regulus's voice answered with equal enthusiasm.

By the time he entered the room, he had Danny perched on his hip, her tiny hands clinging to his collar. His usually composed expression was softened into a rare, tender smile.

"And how's my little morning star today?" he asked, brushing her curls away from her face.

"Hazzy play!" she announced proudly.

"Ah, yes. The famous Hazzy." Regulus's gray eyes flicked to Harry with a smirk. "How are you handling your new identity, son?"

Harry shrugged. "I've accepted my fate."

Danny giggled and buried her face in Regulus's neck.

"She's been chasing him around all day," Y/N said with a laugh.

"Hazzy run fast," Danny agreed, peeking out with wide grey eyes. "Danny run too!"

"Oh, do you now?" Regulus asked, raising an eyebrow. "Well, maybe Baba will have to race you later."

"Race!" Danny pumped her fists in the air.

Regulus sat beside Y/N, his arm resting along the back of the couch. Danny squirmed until she was back on the floor, wobbling over to Harry.

"Hazzy, run!" she commanded.

Harry gave his parents an exaggerated sigh. "Duty calls," he said before launching into a playful chase.

Y/N leaned her head on Regulus's shoulder, watching them with a soft smile.

"She's getting so big," she murmured.

"Too big," Regulus agreed. "And that name's going to stick, isn't it?"

"Absolutely," Y/N said, laughing as Harry darted around the coffee table with Danny hot on his heels. "Hazzy's here to stay."

And as Danny's delighted laughter echoed through the house, it was hard to imagine life any other way.

The soft morning light filtered through the curtains, casting golden patterns across the bedroom floor. Y/N stirred, her eyes fluttering open just as the door creaked. She turned her head and smiled softly at the sight of Harry and Danny standing in the doorway, hand-in-hand.

Harry's chesnut hair stuck up in every direction, defying gravity as usual, while Danny's black curls were tangled into an impressive bird's nest. The two siblings were still in their pajamas: Harry's covered in faded Quidditch brooms, Danny's patterned with tiny moon and stars.

"Hazzy," Danny whispered, tugging on her brother's hand. "Mama wake?"

"Yeah, Danny," Harry reassured her, squeezing her fingers. "See? Mama's awake."

Y/N sat up, tucking the blanket around her legs. "Good morning, my loves," she greeted softly.

Danny beamed, revealing the gap where her front tooth had recently fallen out. "Mama!" She let go of Harry's hand and barreled across the room, climbing clumsily onto the bed. "I had dream 'bout dragon!"

"Did you?" Y/N caught her daughter and pulled her into her lap. "Was it scary?"

Danny shook her head fiercely. "No! Big dragon, nice dragon! Hazzy say it like Uncle Charlie's dragon."

"Ah," Y/N chuckled, glancing toward Harry as he shuffled into the room. "Your brother knows a lot about dragons."

Harry gave a sheepish smile and climbed onto the bed beside them. "I just told her about Norberta," he said, leaning into his mother's side. "Danny likes dragons now."

"I see," Y/N mused, brushing Danny's wild curls with her fingers. "Maybe one day we'll visit Uncle Charlie in Romania and see real dragons."

Danny gasped. "We go? See dragon?"

"One day," Y/N promised.

The sound of footsteps interrupted them. Regulus appeared in the doorway, hair tousled and wand in hand, eyes sharp until he took in the sight before him. "Merlin," he exhaled, lowering his wand. "I thought I heard an intruder."

"Hazzy and Danny," Danny said proudly, throwing her arms wide. "Not 'truder!"

Regulus grinned and crossed the room, sliding his wand into his pajama pocket. "No, you and your brother are definitely not intruders." He sat on the edge of the bed and ruffled Harry's hair, not that it made any difference. "Why are you two up so early?"

"Danny had a dragon dream," Harry answered, tilting his head toward his sister. "Wanted Mama and Baba to know."

Regulus nodded solemnly. "Dreams about dragons are very important. Good thing you told us, Danny."

Danny's eyes sparkled. "I 'member the dragon name!"

"Oh?" Y/N asked. "What's its name, sweetheart?"

Danny scrunched her nose in thought, then declared, "Spork!"

There was a beat of silence before Harry snorted with laughter. "Spork? That's not a dragon name!"

"Is too!" Danny huffed.

"Spork the Dragon," Regulus said with mock seriousness. "A fearsome creature is known across the land for its...sporkiness."

Harry collapsed into giggles, and Danny clapped her hands in delight. Y/N just shook her head fondly. "You're encouraging her."

"Absolutely," Regulus said, reaching out to pull Y/N closer. "She gets her creativity from you."

Danny snuggled into Y/N's lap, thumb slipping into her mouth as the excitement wore off. Harry stretched and leaned against Regulus's shoulder.

"Family nap?" Y/N suggested.

"Family nap," Regulus agreed, flicking his wand to dim the sunlight.

Soon, tangled curls and messy hair were nestled together in a cozy, sleepy pile of warmth and love.

The snow had fallen thick and heavy overnight, blanketing the Black-Potter garden in a pristine, shimmering layer of white. From the warmth of the living room, three-year-old Danica Potter-Black pressed her nose against the frosted window, her wide gray eyes sparkling with excitement.

"Hazzy! Hazzy!" she squealed, spinning around and racing toward her brother. Her curls bounced wildly with each step. "Look! Snow! Lots and lots!"

Harry, now seven years old and quite proud of his 'big brother' status, looked up from the enchanted chessboard where his pieces were grumbling about his last move. He followed her pointing finger to the window and grinned. "You wanna go build a snowman?"

"Yes! Yes! Snowman!" Danny clapped her hands, hopping in place.

"Okay, okay! Let's get our coats."

The two of them bundled up under Y/N's watchful eye. Harry wriggled into his green scarf while Danny impatiently thrust her tiny arms into her puffy coat. Her mittens dangled from strings through the sleeves, and Harry helped her tug them on properly.

"Be careful out there, you two," Y/N called from the door. "And don't eat the snow unless you're sure it's clean!"

"Mama!" Danny giggled. "I'm not gonna eat snow!"

"We'll be careful!" Harry promised.

The garden was a winter wonderland. Their boots crunched on the fresh snow, and their breath clouded in the crisp air. Harry immediately started rolling a ball for the base of their snowman. Danny tried to mimic him, but her ball mostly crumbled.

"Hazzy," she pouted, "mine's not workin'."

"Here, like this." Harry knelt beside her, guiding her hands to press the snow gently and roll it across the ground. "See?"

"Ooooh! I do it!" Danny's face lit up as her snowball grew.

Together, they built a lopsided but proud snowman. Danny insisted he needed a 'silly face,' so Harry found sticks for the arms while she stuck stones into the snow in a haphazard grin. Harry placed his own scarf around its neck and stepped back. "What do you think?"

Danny squinted critically at their creation. "Hazzy, he's cold."

"Well...yeah," Harry said, puzzled. "He's a snowman."

"Needs a hat," she declared. "For warm!"

"Okay, let's get one."

The door opened before they reached the house. Regulus stood there, holding a knitted hat with a bemused expression. "I heard we have a cold snowman in need of a hat?"

"Baba!" Danny ran to him, wrapping her arms around his leg. "We made a snowman! Hazzy helped!"

"I saw," Regulus said, placing the hat on her head for a moment before transferring it to the snowman's icy head. "Looks like a very happy snowman."

Danny beamed and turned back to the snowman. "Now he's warm," she said with satisfaction.

Harry ruffled her hair. "Good job, Snow Queen."

Danny giggled, reaching for a handful of snow. Without warning, she flung it at Harry. It splattered against his coat.

"Oh, you're in for it now!" Harry scooped up snow in both hands.

Screaming with laughter, Danny tried to dodge but ended up flat on her back in the snow, her curls dusted white. "Hazzy! Noooo!"

Regulus shook his head with a smile, leaning against the doorframe as his children tumbled about in the snow. Y/N appeared beside him, slipping her hand into his.

"They're growing up so fast," she murmured.

"They are," Regulus agreed, squeezing her fingers. "But right now, they're exactly where they should be."

A snowball suddenly splattered against Regulus's chest. He looked down in shock to find Danny standing there, cheeks pink with cold and triumph.

"Baba!" she shrieked with glee.

Y/N burst into laughter as Regulus grabbed a handful of snow and raised an eyebrow. "Oh, you started it now, little star."

The snowy battle that followed became a memory they'd cherish for years to come.

FOUR-YEAR-OLD DANY AND EIGHT-YEAR-OLD HARRY

The Black-Potter household was quiet, the warm glow of the hearth casting faint shadows along the walls. Outside, the moon hung low in the sky, bathing the snowy ground in silver light. Inside, however, two little figures shuffled across the carpeted hallway, their steps careful and hushed.

"Shh, Danny," whispered eight-year-old Harry, glancing back at his sister. "You're being loud."

"I'm not!" Danny pouted, her black curls bouncing as she clutched her stuffed dragon tightly. "Hazzy, my feet are just squeaky."

Harry stifled a laugh. "Okay, just...less squeaky feet, alright?"

Danny nodded solemnly and adjusted her grip on her dragon. Together, they tiptoed toward the kitchen.

The kitchen door creaked as Harry slowly pushed it open. He froze, holding his breath. Danny copied him, her wide eyes fixed on his face. After a long moment of silence, they exchanged triumphant grins and slipped inside.

"Alright," Harry whispered, "the cookies should be in the blue tin."

Danny squinted at the counter. "That's really high," she said, voice heavy with skepticism.

"That's why we have teamwork," Harry declared, dragging a chair across the floor with a low screech. They both winced, then stared at the doorway. No footsteps. No Baba with his scary frown. No Mama with her disappointed head shake.

Harry climbed onto the chair, balancing with practiced ease. "Okay," he murmured, stretching toward the cookie tin. His fingers brushed the lid. "Almost...got it..."

Danny watched, her dragon tucked under her arm, her curls falling in her face. "Hazzy, careful!"

"I'm fine," Harry assured her. With a final stretch, he snagged the tin and pulled it toward him.

The tin wobbled. Harry's heart stopped. The container tilted and tumbled off the edge.

"No!" Danny gasped.

Harry lunged and caught it mid-air. "Ha! Got it!"

Danny clapped her hands silently. "You're the bestest," she whispered.

Harry hopped down and opened the tin. The rich scent of chocolate-chip cookies drifted into the air. "Okay, Danny, take one."

Danny's eyes lit up as she reached in and grabbed the biggest cookie she could find. Harry took one for himself, then replaced the lid and carefully slid the tin under the table.

They turned toward the door just as the kitchen light snapped on.

"And what do we have here?"

The siblings froze mid-chew.

Regulus Black stood in the doorway, arms crossed, dark hair mussed from sleep. His grey eyes were sharp, but his lips twitched at the corners.

Danny let out a muffled squeak and ducked behind Harry. "Uh-oh," she whispered.

"Uh-oh is right," Regulus said, stepping forward. "Midnight cookie thieves, I see."

"We're not thieves," Harry said quickly. "We're...we're taste testers."

"Yeah," Danny piped up, peeking around Harry. "Mama said cookies gotta be tasted."

Regulus arched a brow. "Did she?"

Harry gulped. "Well, not these cookies. But...cookies in general."

"Mmm." Regulus knelt down so he was eye-level with them. "Do taste testers usually sneak around in the dark?"

"Only when it's a secret mission," Danny whispered.

Regulus pressed his lips together, trying not to smile. "Well, in that case," he said softly, "I guess you'll need a lookout next time."

Harry's mouth fell open. "Wait...you're not mad?"

"Oh, I'm mad," Regulus said, though his voice lacked any bite. "But I'll let it slide this time. Now, off to bed, you two."

"Yes, Baba," they chorused.

As he herded them back to their rooms, Regulus glanced up and met Y/N's amused gaze from the top of the stairs.

"Told you they'd go for the cookies," she whispered.

"You set us up!" Harry exclaimed.

Danny gasped. "Mama!"

Y/N laughed softly. "What can I say? I know my little cookie monsters." She leaned down to kiss the tops of their heads. "Now, go to sleep. We'll discuss your sneaky skills in the morning."

As Harry and Danny shuffled into their rooms, Regulus smiled to himself. Nights like these made every sleep-deprived morning worth it.

FIVE-YEAR-OLD DANNY AND NINE-YEAR-OLD HARRY

The Black-Potter household was rarely quiet, especially with an energetic four-year-old like Danny and a lively eight-year-old like Harry running about. Laughter, footsteps racing down hallways, and the occasional magical mishap filled the air with a warmth that made Grimmauld Place feel more like home than it ever had before. But today, the usual harmony was broken by the sharp crack of a slammed door.

"You're mean, Hazzy!" Danny's tiny voice, thick with tears, echoed down the hall.

Harry stood frozen just outside his bedroom door, his chest tight with guilt. Moments ago, they'd been playing with his toy broomstick. Danny had begged for a turn, but Harry had refused, insisting she was too little and would just break it. When she'd tried to grab it anyway, he'd snapped at her.

"You're just a baby," he'd said. "You don't know how to fly right."

The words had hit harder than any hex. Danny's face had crumpled, her big gray eyes filling with tears. Then she'd run to her room and slammed the door, leaving Harry with the broomstick in his hands and regret in his heart.

From downstairs, Y/N heard the door slam and exchanged a knowing look with Regulus, who was levitating a stack of books onto a high shelf.

"Sounds like trouble," she said.

"Sounds like our children," Regulus replied, lowering the last book into place. "Shall I play the terrifying father figure?"

Y/N arched an eyebrow. "Terrifying? You?"

"I was once a Death Eater."

"Mm-hmm," she said, amused. "Why don't you try the compassionate father figure instead?"

"I'll give it my best shot," Regulus said, following her up the stairs.

They found Harry slumped against the wall outside Danny's door, twirling the toy broom in his hands. His shoulders sagged under the weight of his remorse.

"Rough day, kiddo?" Y/N asked gently as she crouched beside him.

Harry's bottom lip jutted out slightly, though he tried to hide it. "I made Danny cry."

Regulus sat down on Harry's other side. "Yeah, we heard," he said softly. "Want to tell us what happened?"

"She wanted to fly my broom," Harry mumbled. "I said no because she's little. And then she tried to take it anyway, and I... I said she was a baby."

Y/N winced. "Ah," she said. "Calling your sister a baby? That'll sting."

"She is a baby," Harry muttered, but even he didn't sound convinced.

"She doesn't see it that way," Regulus said. "She looks up to you, Harry. She wants to do what you do. Be like you. So when you said she was a baby, she probably felt like...you thought she wasn't good enough."

Harry's eyes widened. "I didn't mean that."

"I know," Regulus reassured him. "But sometimes, what we say doesn't match what we feel."

Y/N brushed Harry's hair back fondly. "Being a big brother is hard sometimes. You have to find a way to teach her without making her feel small."

"So...what do I do now?" Harry asked.

"Start with an apology," Y/N said.

Harry took a deep breath, then knocked on Danny's door. "Danny? Can I come in?"

There was a long silence. Then a muffled "Go 'way."

"Please?" Harry tried again. "I'm really sorry. I was mean, and I didn't mean to be."

The door creaked open an inch. One gray eye peeked through the gap.

"You called me a baby," Danny said, voice wobbly.

"I know," Harry said, his heart aching at the sight of her tear-streaked face. "I'm sorry. You're not a baby. You're my sister, and you're really brave and smart. I was just scared you'd fall and get hurt."

Danny opened the door a bit more. "You scared for me?"

"Yeah," Harry said. "'Cause I love you."

Danny's lips trembled. Then, with a tiny sniff, she launched herself at Harry, wrapping her arms around his waist. "I love you too, Hazzy," she mumbled into his shirt.

From their spot down the hall, Y/N and Regulus exchanged smiles.

"Think they'll remember this the next time they fight?" Y/N asked softly.

"Not a chance," Regulus replied with a chuckle. "But we'll be here to remind them."

And as Harry pulled Danny into his room to give her a broomstick-flying lesson, the warmth of family settled back into the house once more.

SIX-YEAR-OLD DANNY AND TEN-YEAR-OLD HARRY

The smell of buttery toast and sizzling bacon filled the cozy kitchen of the Black-Potter household. ten-year-old Harry sat at the table, munching on a piece of toast, while six-year-old Danica, her wild dark curls sticking in every direction, gleefully smashed her scrambled eggs with her spoon.

"Danny, you're supposed to eat that," Harry said, raising an eyebrow.

Danica grinned, her green eyes twinkling with mischief. "I am! But first, I have to make it flat. Flat eggs taste better."

Harry sighed dramatically but couldn't help smiling. His little sister always had a very particular way of doing things. "Whatever you say, munchkin."

As Danica resumed her egg-flattening mission, footsteps echoed from the hallway. Harry glanced up just in time to see his father, Regulus, stroll into the kitchen. His hair was slightly damp from a shower, and he wore his usual elegant but relaxed expression. Without a word, Regulus walked straight to where Y/N stood at the stove, flipping pancakes.

"Good morning, my love," Regulus murmured, slipping his arms around her waist from behind. He dipped his head and pressed a soft kiss to her cheek.

"Morning," Y/N replied with a smile, leaning into his embrace.

Regulus, however, wasn't content with just one kiss. He trailed a series of gentle kisses along her jawline, then down to the curve of her neck. Y/N giggled softly as he nuzzled the sensitive spot near her ear.

"Regulus Black," she scolded half-heartedly, "the kids are right there."

"Let them learn what true love looks like," Regulus replied with a smirk before pressing a kiss to her temple.

Across the table, Harry froze mid-chew. Danica stopped smashing her eggs. The siblings locked eyes, and without a word, both scrunched their noses and made loud, exaggerated gagging noises.

"Blech! Gross!"

"Ewwwww! Baba's kissing Mama!" Danica squealed, dropping her spoon and covering her eyes with sticky fingers. "Hazzy, make it stop!"

Harry clutched his chest dramatically. "I think I'm gonna be sick," he groaned, slumping over the table.

Regulus lifted his head and arched a single eyebrow at his children. "You two are impossible," he drawled, though amusement danced in his gray eyes.

Y/N laughed, turning to face him. "Told you," she teased.

"Kissing's gross!" Danica declared from behind her tiny hands.

"Yeah, Baba," Harry agreed, sitting back up with an exaggerated shudder. "Keep the mushy stuff private, will you?"

"Private?" Regulus echoed, feigning offense. "This is my home, my kitchen, and my wife. I can kiss her whenever I want."

"Not in front of us!" Danica insisted, peeking through her fingers.

Y/N leaned her head against Regulus's chest and laughed. "Maybe we should tone it down," she said.

"Hmm," Regulus hummed as if considering it. Then, with a devilish grin, he planted a loud, exaggerated kiss on Y/N's cheek.

"EWWWW!" Harry and Danica chorused.

Danica dramatically slid off her chair and collapsed onto the floor. "I've been poisoned!" she moaned, splaying her limbs across the tiles.

Harry followed suit, flopping onto the ground beside her. "We're doomed! Doomed by parental affection!"

Y/N pressed a hand to her mouth to stifle her laughter while Regulus smirked down at his children. "Ah, well," he said. "If you're both doomed, that means more pancakes for me and your mother."

Danica's eyes popped open. "Wait! I'm not doomed! I'm hungry!"

Harry sat up immediately. "Me too!"

"Mysterious recovery," Regulus mused as he helped them both back into their chairs.

Y/N plated the pancakes and set them on the table. As everyone dug in, Regulus reached for Y/N's hand under the table and squeezed it.

Harry saw the gesture but let it slide this time. Mostly because there were pancakes. And pancakes always came first.

The soft glow of candlelight filled the cozy Black-Potter living room, casting flickering shadows along the walls. Outside, snowflakes drifted down like bits of silver confetti, frosting the windows in delicate lace patterns. Y/N sat curled up on the couch, one hand resting on the small but unmistakable curve of her stomach. Across from her, Regulus paced with the anxiety of a man who once battled dark forces but now faced something infinitely more daunting: telling Harry he was going to have a sibling.

"You're going to wear a hole in the rug," Y/N murmured, a smile tugging at her lips.

"I'm trying to figure out the right words," Regulus said, stopping mid-stride. He ran a hand through his hair, his brow furrowed. "How do you tell a six-year-old that everything is about to change?"

Y/N patted the cushion beside her. "We tell him with love. And honesty." She tilted her head toward the staircase. "He's probably still awake, you know."

Regulus sighed, resigned, and climbed the stairs. Moments later, he returned, Harry perched sleepily on his hip. The boy's messy black hair stuck out at odd angles, his green eyes blinking in the dim light.

"Mama? Baba?" Harry rubbed his eyes. "Why am I awake?"

Regulus settled Harry between them on the couch. Y/N shifted to face him fully, brushing his hair back fondly.

"We have something important to tell you," she began.

Harry's eyes widened. "Is it bad?"

"No, sweetheart," Y/N said softly. "It's something wonderful." She exchanged a glance with Regulus before taking a breath. "You're going to be a big brother."

Harry froze. He looked from Y/N's belly to Regulus, and then back again. "A brother?"

"Or a sister," Regulus said. "We don't know yet."

Harry's mouth formed a small "o." Silence stretched between them like a fragile thread.

"Are you excited?" Y/N asked, her voice gentle.

Harry's legs swung against the couch. "I dunno. Will you still have time for me?"

Y/N's heart cracked at the uncertainty in his voice. She pulled him into her arms, cradling him tightly. "Oh, my love. There is nothing and no one that could ever replace you. You made us parents. And we will always have time for you. Always."

Harry sniffled into her shoulder. "Promise?"

"I swear it," Y/N said.

Regulus leaned in and kissed the crown of Harry's head. "You'll never be alone, Harry. You'll have us. And you'll have a little brother or sister to protect, to teach...maybe even to prank if you inherit any of your Uncle Sirius's tendencies."

That earned a watery giggle. Harry looked up. "I get to teach them stuff?"

"Absolutely," Y/N said with a smile. "Like how to fly a broom and sneak extra biscuits from the kitchen when Baba isn't looking."

"Oi!" Regulus shot her a look of mock disapproval, but his eyes were warm.

Harry's grin grew. "Okay," he whispered. "I think being a big brother sounds kinda cool."

Y/N pressed a kiss to his forehead. "You're going to be the best big brother ever, sweetheart."

That night, after Harry had fallen asleep between them, one hand resting protectively on Y/N's belly, Regulus whispered into the darkness, "He's going to be okay. We're going to be okay."

Y/N laced her fingers with his. "We already are."

-

The sun was barely peeking over the horizon when six-year-old Harry Potter-Black was woken up by the sound of soft footsteps. His wild hair stuck up in every direction as he rubbed his eyes and squinted at the doorway of his bedroom.

His Baba stood there, hair disheveled, an uncharacteristically wide grin on his usually serious face.

"Harry," Regulus whispered, voice thick with emotion. "She's here. Your sister's here."

Harry didn't need any more convincing. He scrambled out of bed, heart racing with excitement. "She's really here?" he asked breathlessly.

Regulus held out his hand, and Harry grabbed it tightly as they padded down the hall toward the master bedroom. The door was slightly ajar, and Harry peeked in.

His Mama was propped up against pillows, hair damp and face glowing with a tired but radiant smile. In her arms was a tiny bundle wrapped in a soft, moon-patterned blanket.

"Hi, sweetheart," Y/N whispered as Harry hesitated in the doorway. "Come meet your sister."

Harry crept forward, eyes wide. "She's so small," he breathed, standing on his tiptoes to see better.

"Would you like to hold her?" Y/N asked softly.

Harry's green eyes shot up to hers. "Can I?"

Y/N nodded, shifting slightly as Regulus moved to sit beside her, guiding Harry into the safe space between them. With infinite care, they helped him cradle the tiny baby.

"This is Danica," Y/N said, brushing a gentle finger along the baby's soft cheek. "Danica Potter-Black."

"Danny," Harry whispered, staring at the delicate face. "Hi, Danny. I'm your big brother. I'm gonna take care of you forever."

Danica gave a tiny sigh, her tiny fingers curling into a fist. Harry's heart melted.

"She's like a morning star," he whispered.

Regulus wrapped an arm around his son. "That's exactly what her name means, Harry. Morning star."

Harry beamed. "I love her already."

Y/N felt her heart squeeze with happiness as she met Regulus's gaze over their children's heads. At that moment, their little family felt complete.

Meeting Walburga

Regulus brings Harry to meet his grandmother

[Regulus Black x Fem Potter! reader]

word count: 785

warnings: hurt/comfort, Walburga being a meanie to Harry

-

Regulus wasn’t entirely sure why he agreed to this.

It was a terrible idea. He knew that. Y/N knew that. Even Kreacher, who had loyally followed him into this new life, had given him a wary look when he mentioned visiting 12 Grimmauld Place.

Yet, here they were.

Harry held Regulus’ hand tightly as they stood outside the Black family’s ancestral home. The looming townhouse was as dark and unwelcoming as ever, its iron-wrought serpent door knocker glinting in the dim London light. Regulus exhaled sharply, tightening his grip on his son’s small hand.

“Stay close to me,” he murmured.

Harry nodded, his green eyes wide as he stared up at the tall building. “Are you sure she won’t like… hex me?” he whispered, only half-joking.

Regulus almost smirked. She would if she could.

Instead, he knocked.

The door swung open almost immediately, revealing Kreacher. His large, bat-like ears twitched as he looked down at Harry. For a long moment, he was silent, his expression unreadable. Then, to Harry’s surprise, the elf bowed low.

“Master Regulus,” he croaked. “Young Master Potter.”

Harry’s eyebrows shot up. Master Potter? No one had ever called him that before.

Regulus gave a curt nod, stepping inside and ushering Harry in after him. The house smelled the same—dust, old magic, and a hint of something burning in the fireplace. The walls were lined with dark portraits, and Harry nearly jumped as one of them moved.

But before he could get a proper look, a voice rang through the house—sharp, commanding, and dripping with disdain.

“Regulus.”

Harry turned toward the voice and saw her.

Walburga Black stood at the foot of the grand staircase, dressed in deep emerald green. Her sharp features were set in stone, her dark eyes taking in her son before shifting to Harry.

The temperature in the room seemed to drop.

Regulus straightened his shoulders, his grip on Harry’s hand firm. “Mother.”

Walburga’s lips thinned as her gaze swept over Harry like he was an insect. “So,” she said slowly, coldly. “This is what you’ve been reduced to. Raising a half-blood.”

Harry stiffened, instinctively stepping closer to Regulus.

Regulus’ expression didn’t change. “He is my son.”

Walburga scoffed. “He is James Potter’s son.” Her voice was venomous. “A disgrace to the family name.”

Harry felt his face grow hot, but before he could say anything, Regulus spoke—his voice steady, but edged with steel.

“He is my son,” he repeated, quieter this time. “And I will not tolerate you speaking of him that way.”

Walburga’s eyes darkened. “You dare bring him into this house?”

“I brought him here so you could meet your grandson,” Regulus said, his tone even. “Not to hear your outdated prejudices.”

Harry bit his lip, gripping Regulus’ sleeve. He didn’t understand everything, but he knew she didn’t like him. He could feel it.

For a long, tense moment, Walburga simply stared at them.

Then, to Harry’s utter shock, she let out a low chuckle.

“You’ve changed,” she murmured, her gaze locked onto Regulus. “Not that it matters. The blood in your veins remains the same. That thing” —her eyes flicked to Harry— “does not.”

Harry flinched.

Regulus’ jaw tightened. “Come, Harry,” he said, his voice calm but firm. “We’re leaving.”

Harry didn’t hesitate, stepping quickly in line beside him as Regulus turned on his heel.

As they reached the door, Walburga’s voice rang out again.

“When the time comes,” she said, “you’ll regret your choices, Regulus.”

Regulus didn’t stop walking.

Kreacher, who had remained silent through the exchange, gave a deep bow as they passed.

As soon as they stepped outside, Harry let out a breath he hadn’t realized he’d been holding.

Regulus glanced down at him. “Are you alright?”

Harry hesitated, then nodded. “…She doesn’t like me.”

Regulus sighed, running a hand through his dark hair. “That doesn’t matter,” he muttered. Then, more softly, “I do.”

Harry blinked up at him.

“…Mama does, too,” he said after a moment.

Regulus smirked. “Of course she does. She’s your mother.”

Harry smiled a little, shuffling closer to Regulus as they started walking again.

“…Do you think Kreacher likes me?”

Regulus chuckled, glancing back at the house. “I think he’s figuring it out.”

Harry hummed. “I liked him.”

Regulus raised a brow. “You did?”

“He bowed,” Harry said simply. “I think that means he kinda likes me.”

Regulus shook his head in amusement. “You are far too optimistic.”

But as they made their way home, he found himself silently grateful.

Harry would never know the cold walls of that house. He would never be raised in darkness, surrounded by cruel whispers of blood purity and superiority.

He had a family.

A real one.

Mom and Dad.

While Regulus is at work, Y/N brings Harry to his parents' grave.

[Regulus Black x Fem Potter!reader]

word count: 558 words.

warnings: Angst, mentions of death

note: This is the fourth chapter of my Potter-Black series but Regulus is hardly mentioned. This is because the chapter is focused on Harry, Y/N, Lily, and James.

-

The morning was crisp, the air carrying the scent of damp earth as Y/N wrapped Harry’s scarf snugly around his small frame. The autumn leaves crunched beneath their feet as they walked up the familiar path leading to the graveyard in Godric’s Hollow.

Regulus was at the Ministry, drowning in paperwork, leaving Y/N with the quiet decision to visit her brother alone—well, almost alone.

Harry, bundled up in his coat and mittens, clutched her hand tightly. “Mama,” he asked, his voice soft, “why are we here?”

Y/N knelt beside him, brushing a few stray leaves from his curls. “We’re visiting your parents, love.”

Harry’s brow furrowed slightly, his young mind trying to piece it together. “My real mummy and daddy?”

Y/N swallowed past the lump in her throat and nodded. “Yes. Your Mama Lily and Daddy James.”

Harry’s grip on her hand tightened as he looked around. “But I never met them,” he whispered.

Y/N gave him a sad smile. “No, sweetheart. You were just a baby.” She cupped his cheek gently. “But they loved you so much.”

Hand in hand, they walked through the graveyard, past old, weathered headstones, until they reached the one she knew by heart.

Y/N let out a slow breath, kneeling before the headstone. Harry hesitated before mirroring her, his tiny fingers tracing the carved letters of their names.

“James Potter…” he murmured, then looked up at Y/N. “That’s my name too, right?”

She smiled softly. “Yes, love. Harry James Potter. Your daddy wanted you to have his name.”

Harry was quiet for a moment, then looked back at the grave. “Do you think he’d like me?” he asked hesitantly. “Daddy James?”

Y/N’s heart clenched, and she pulled him into a hug. “Oh, Harry,” she whispered, pressing a kiss to his forehead. “He would have adored you. You’re just like him—kind, brave, full of mischief.” She chuckled softly, stroking his messy black hair. “And you have your mama’s heart. So full of love.”

Harry’s little arms wrapped around her neck. “I wish I could meet them.”

Y/N closed her eyes against the sting of tears. “I know, sweetheart. Me too.”

For a long moment, they sat in silence, Y/N’s arms wrapped protectively around the little boy she had sworn to raise, to love, to keep safe.

After a while, Harry shifted in her embrace. “Do you think they can see me?”

Y/N let out a soft breath, glancing up at the sky. “I do,” she said firmly. “I think they watch over you every single day.”

Harry thought about that, then looked back at the grave. After a moment, he reached into his coat pocket and pulled something out.

A small, slightly battered toy stag.

His favorite.

Carefully, he placed it at the base of the headstone, patting it gently.

“You can have Prongsie,” he whispered. “I think you’d like him.”

Y/N had to bite her lip to keep herself from crying.

As the wind rustled through the trees, Harry turned back to her and asked, “Can we come back again?”

Y/N smiled, cupping his face. “Of course, love. As many times as you want.”

She took his hand once more, pressing one last kiss to the headstone before leading him away.

As they left, the autumn wind carried the sound of distant laughter, like a whisper of the past. And for the first time in a long time, Y/N swore she could feel her brother’s presence—warm, watching, proud.

Glasses !

SUMMARY: Y/N and Regulus take Harry to get glasses after he bumps straight into the door frame.

[Regulus Black x Fem Potter! reader]

warnings: Fluff, slightly humorous

words: 0.6k

It started with small things.

Harry missing his cup when reaching for his pumpkin juice at breakfast. Squinting at his books when Y/N or Regulus tried to get him to read. Tripping over his own feet more often than usual. At first, they thought it was just clumsiness—he was four, after all.

Then he walked straight into the doorframe.

Regulus, who had been sipping his tea, barely blinked as Harry let out a small oof and stumbled backward, rubbing his forehead. Y/N, however, immediately crouched down beside him.

“Harry, love, are you alright?” she asked, brushing his messy hair away to check for any bumps.

Harry pouted, rubbing his forehead. “The door moved.”

Regulus raised an unimpressed eyebrow. “No, it didn’t.”

Harry crossed his arms. “Well, it felt like it did.”

Y/N hummed, glancing at Regulus before looking back at Harry. “Sweetheart, have you been having trouble seeing things lately?”

Harry shrugged. “I dunno.”

Regulus sighed, setting down his tea. “I think we need to take him to the eye healer.”

Harry’s eyes widened in alarm. “A what?”

Y/N chuckled, adjusting her own glasses. “Someone who helps people see better. Like how I wear glasses, remember?”

Harry blinked, looking up at her. “Oh… but you look good in glasses.”

Y/N grinned. “And you will too if you need them.”

Harry frowned but didn’t argue.

The next day, after breakfast (which involved Sirius trying to convince Harry to wear an eyepatch instead of glasses because it was ‘cooler’), they made their way to St. Mungo’s Department of Magical Vision and Sight.

Harry swung his legs idly from his chair in the waiting area, glancing at Y/N. “Did you have to get glasses when you were little too?”

She smiled. “I did. I was about your age when my mum took me for my first pair.”

Harry considered this. “Did Daddy James wear them too?”

Y/N’s smile softened. “Yes, he did. Since he was a boy.”

Harry looked thoughtful. “Maybe I should get glasses… then I’ll match you and Daddy James.”

Regulus snorted. “As if you had a choice.”

Before Harry could respond, the healer called them in.

The eye healer, an older wizard with kind eyes, greeted them warmly. “Alright, young man, let’s see how those eyes are working.”

Harry went through a series of tests, from reading different-sized letters to following a floating quill with his eyes. He giggled when the quill changed colors but frowned when he struggled with some of the smaller letters.

After a few more checks, Healer Aldwyn nodded. “Well, my boy, you’re a bit nearsighted. Not too bad, but you’ll need some glasses to help you see clearly.”

Harry gasped. “Like Mama?”

Y/N smiled. “Just like me, love.”

Harry beamed. “Then I want glasses!”

At the attached vision shop, Harry tried on several pairs, wrinkling his nose at most of them.

“These,” he finally said, grabbing a pair of small, round frames. “They look like Mama’s, but smaller!”

Y/N’s heart melted. “Oh, love, you look adorable.”

Regulus smirked. “Now he just needs to start losing all of his books like you do.”

Y/N rolled her eyes and nudged him playfully.

As they walked out, Harry kept adjusting his glasses, looking around in amazement. “I can see so much! Look, Baba! The clouds are so fluffy! And the sign isn’t blurry anymore!”

Regulus smirked. “That is the point of glasses, Harry.”

Harry grinned up at Y/N. “We match now, Mama!”

Y/N ruffled his hair. “Yes, we do, love.”

Regulus glanced between them, then sighed. “Great. Now there are two of you.”

Y/N smirked. “Poor you.”

Harry giggled, and the three of them headed home—where Sirius, upon seeing Harry’s glasses, dramatically clutched his chest and declared, “MY GODSON LOOKS JUST LIKE JAMES! I’M HAVING AN EMOTIONAL CRISIS!” before proceeding to chase Harry around the house yelling, “NERD ALERT!”

Regulus groaned. Y/N laughed.

And Harry?

He just felt pretty cool.

Learning how to read

Regulus and Y/N try to teach Harry how to read

words: 0.5k

warnings: fluff, not proofread, alive Regulus and Sirius not being in Azkaban

“Alright, Harry, let’s try this again,” Y/N said patiently, tapping the open book in front of them. “What does this word say?”

Harry, sprawled across the plush rug in the Black family library, kicked his legs idly and squinted at the sentence. He traced the letters with his finger, lips moving as he tried to sound it out.

“C… ca… castle?” he guessed hopefully.

Y/N smiled. “Close! It’s a cauldron. You almost had it.”

Harry groaned dramatically and flopped onto his back. “This is so boring.”

Regulus, sitting in a chair nearby with his own book, arched an eyebrow. “Reading is not boring, Harry.”

Harry turned his head to stare at his Baba with a look of deep betrayal. “But it is! There aren’t even any dragons in this book!”

Y/N chuckled. “We have to practice the small words first, love. Then we can move on to dragons.”

Harry pouted. “But I want adventure stories now!”

Regulus sighed, rubbing his temple. “You won’t understand adventure stories if you can’t read properly.”

Harry huffed but reluctantly sat up again. “Fine,” he mumbled, picking up the book. “But only if I get a story about a dragon next.”

Before Y/N could agree, the library doors burst open.

“Never fear, Padfoot is here!” Sirius declared dramatically, striding into the room with a mischievous grin.

Regulus groaned. “Oh, no.”

Harry immediately perked up. “Uncle Siri!” He scrambled to his feet, rushing toward him.

Sirius scooped him up and twirled him in the air. “My favorite little troublemaker! What are you up to?”

“Reading lessons,” Y/N answered, crossing her arms.

Sirius wrinkled his nose. “Ugh. Sounds dull.”

Harry nodded eagerly. “It is!”

Regulus shut his book with a sigh. “We were making progress before you arrived.”

Sirius ignored him, digging into his coat and pulling out something that made Regulus’s eye twitch.

A brightly colored, illustrated comic book.

“Forget the boring old schoolbooks, Harry,” Sirius declared, wiggling the comic in front of him. “If you’re going to read, you should read something fun.”

Harry gasped. “What is it?”

Sirius grinned. “The Adventures of Martin the Mad Muggle!” He flipped open the pages, showing off the dramatic illustrations of a confused Muggle accidentally causing magical mayhem wherever he went.

Harry’s eyes widened in delight. “That looks amazing!”

Regulus pinched the bridge of his nose. “Absolutely not.”

“Absolutely yes,” Sirius shot back, smirking.

Y/N sighed, hiding her amusement. “Sirius, you’re not exactly helping.”

“Oh, come on,” Sirius said, plopping onto the rug beside Harry. “Think of it as… incentive! He wants adventure stories? Let him practice with this!”

Regulus glared. “That is not proper literature.”

Harry, meanwhile, was already flipping through the comic excitedly. “Look, Baba! There’s a dragon in this one!”

Regulus groaned as Y/N stifled a laugh.

Sirius winked. “See? Learning can be fun.”

Regulus muttered something under his breath that sounded suspicious like ‘you are the bane of my existence’, but ultimately, he sighed in defeat.

Y/N ruffled Harry’s hair and smirked at Sirius. “Fine. But if he starts writing his letters backward because of those ridiculous fonts, I’m blaming you.”

Sirius grinned, slinging an arm around his godson. “Deal.”

Harry, completely oblivious to the war being waged over his reading material, beamed. “This is the best lesson ever!”

Regulus groaned again.

Uncle Moony and Siri 🌟

Uncle Moony and Uncle Siri visit

[regulus black x fem potter! reader]

warnings: fluff

It was a quiet morning at the Potter-Black household, the kind that Y/N had learned to cherish. The storm from the night before had passed, leaving behind a crisp autumn breeze that drifted through the open windows. Harry sat cross-legged on the living room floor, carefully stacking his wooden blocks, his tongue peeking out in concentration.

Regulus was sitting in the armchair, a book in one hand, a cup of tea in the other, looking as composed as ever. Y/N was beside Harry on the rug, sorting through his toys when suddenly—

BANG. BANG. BANG.

The front door shook under the weight of impatient knocking.

Regulus barely looked up from his book. “I am not answering that,” he muttered, sipping tea.

Y/N sighed, already knowing who it was. “If we ignore him, he’ll just keep knocking louder.”

Sure enough—BANG. BANG. BA—

“Alright, alright!” Y/N called as she stood up and approached the door, throwing it open to reveal a very smug-looking Sirius Black, leaning casually against the frame.

“Why, hello there, darling sister-in-law,” Sirius greeted dramatically. “Your favorite Black has arrived.”

Behind him, Remus stood with a patient smile, holding a small box wrapped in brown paper. “I told him to knock like a normal person,” he said apologetically.

“I did knock like a normal person,” Sirius said, grinning as he stepped inside. “With enthusiasm.”

Y/N rolled her eyes but stepped aside to let them in.

At the sound of new voices, Harry perked up. His little face lit up, and he scrambled to his feet. “Uncle Siri! Uncle Moony!”

Sirius let out a bark of laughter as he scooped Harry up, spinning him in the air. “There’s my favorite kiddo! Getting bigger every time I see you, huh?”

Harry giggled wildly, his tiny hands gripping onto Sirius’s robes. “Faster, Uncle Siri!”

“Not in the house,” Regulus said flatly from his armchair.

Sirius ignored him and did one more spin before setting Harry down.

Remus crouched beside Harry, handing him the small package. “I brought you a little something, Harry,” he said warmly.

Harry gasped, taking the package with wide eyes. “A present?”

“Just a little one,” Remus said with a soft smile. “Go on, open it.”

Harry eagerly tore into the paper, revealing a small enchanted book filled with moving pictures of magical creatures. His face lit up. “Wow!” He carefully flipped through the pages, watching a tiny Hippogriff flap its wings before running to Y/N. “Mama, look!”

“That’s amazing, love,” Y/N said, ruffling his hair. “What do you say to Uncle Moony?”

“Thank you, Uncle Moony!” Harry beamed.

“Anytime, little one,” Remus replied, ruffling his hair in return.

Sirius, meanwhile, flopped dramatically onto the couch, stretching his arms across the back. “So, where’s the good tea? Or—better yet—firewhisky?”

Regulus finally looked up from his book, narrowing his eyes. “It’s eleven in the morning.”

“And?” Sirius smirked. “I was up late doing very important things.”

Y/N raised an eyebrow. “Sirius, was that very important thing a drinking contest with Mad-Eye Moody?”

“… No?”

Remus sighed. “Yes.”

Harry, still absorbed in his book, sat himself right next to Regulus in the armchair, leaning against him. Regulus instinctively wrapped an arm around the boy, holding his book in one hand while absentmindedly carding his fingers through Harry’s messy hair.

Sirius watched them with a smirk. “Never thought I’d see the day. My little brother—a proper parent.”

Regulus shot him a glare. “What is that supposed to mean?”

Sirius grinned. “It means I’m still processing the fact that you—the grumpy, brooding Black—ended up raising my godson instead of me.” He leaned forward, winking at Harry. “But don’t worry kid, I’m the fun uncle. When you get older, I’ll teach you all the best pranks.”

Harry giggled. “Really?”

Regulus scowled. “No.”

“Yes,” Sirius countered, nodding at Harry.

Y/N snorted. “No pranks today, at least. I’d rather not clean up whatever chaos you unleash.”

Sirius sighed dramatically. “Fine, fine. I’ll behave.” He paused, then grinned at Harry. “For now.”

Regulus groaned, rubbing his temple. “Why did I let you into my house?”

Remus chuckled, sipping his tea. “Because you secretly love us.”

Regulus scoffed but didn’t argue.

Y/N just smiled, watching as Harry curled up happily between them all, his laughter filling the house. Whatever storm had been outside last night, whatever nightmares had tried to creep in, Harry was safe here—with his family. Even if Sirius was a bad influence.

One stormy night, the wind howled through the trees, rattling the windowpanes as rain splattered against the glass in uneven bursts. The heavy clouds outside swallowed the moonlight, casting the house into near darkness. Inside his small bedroom, four-year-old Harry Potter tossed and turned, his tiny fingers gripping the soft fabric of his blanket.

Then, a particularly loud crack of thunder split the night, shaking the walls with its ferocity. Harry gasped, his heart hammering in his chest. The sound was too much—too loud, too sudden, too scary. His small body tensed, and tears pricked at the corners of his emerald-green eyes. He sat up quickly, the dim glow of the enchanted nightlight barely doing anything to push back the shadows that seemed to loom larger with every flash of lightning.

Without a second thought, he flung aside his blanket and clutched his beloved stuffed stag, a gift from his Uncle Siri, one he never went to bed without. Holding the plush toy tightly against his chest, he scrambled out of bed, his little feet hitting the cool wooden floor. The hallway stretched ahead of him, dark and unfamiliar in the storm’s flickering light, but he didn’t hesitate. He knew the way by heart.

Each step was cautious yet determined as he padded down the corridor, his breath coming in quiet, hurried puffs. The house groaned under the storm’s weight, and another rumble of thunder sent him into a near run. By the time he reached the large wooden door of his baba and mama’s room, his tiny hands were shaking. With effort, he pushed the door open just enough to slip inside, the comforting scent of home immediately wrapping around him like a warm embrace.

Blinking in the darkness, his bright green eyes searched for them, his safe place. The familiar figures of Y/N and Regulus lay curled together beneath the blankets, the rhythmic sound of their breathing a soft lull against the storm’s fury outside. He didn’t hesitate. With a soft sniffle, he scrambled up onto the bed, crawling between them and pressing himself into the warmth of their bodies.

“Mama… Baba…” he whispered sleepily, his voice small and frightened. “The sky is loud.”

Regulus stirred first, groggy but instinctively protective, his arm curling around Harry and pulling him close. “Mmm…” he hummed in acknowledgment, his voice thick with sleep. “It’s alright, Harry”

Y/N shifted as well, barely opening her eyes before instinctively reaching out, her fingers brushing through Harry’s wild, untamed hair. The feel of his small frame trembling slightly made her frown, and she gently pressed a kiss to his forehead. “You’re safe, love,” she murmured, her voice warm and reassuring despite her drowsiness. “The thunder can’t hurt you.”

Regulus, still half-asleep, let out a low hum of agreement, his hand rubbing slow, soothing circles on Harry’s back. “Just the clouds talking to each other,” he murmured.

Harry buried his face against Y/N’s side, his small fingers clutching at the fabric of her nightshirt. “Don’t want the sky to talk anymore…” he mumbled, his words slightly muffled by sleep.

Y/N chuckled softly, exchanging a knowing glance with Regulus over their son’s head. Thunderstorms had never bothered her much, nor did they seem to faze Regulus, but she knew to Harry, that each roar of thunder felt like a monster lurking in the dark.

“Well then,” she whispered, brushing her fingers through his hair in slow, comforting strokes. “We’ll just have to drown it out, won’t we?”

Harry peeked up at her with tired, curious eyes. “How?” he asked softly, still gripping his stuffed stag.

“With a bedtime story, of course,” she said, her voice gentle and sure.

Regulus gave a sleepy chuckle, shifting slightly but not letting go of Harry. “Hmm… make it a good one,” he murmured, already half-asleep again.

Y/N smiled as she began weaving a tale, her voice soft and rhythmic, each word forming a safe, warm cocoon around them. Harry’s little body relaxed further, his breathing evening out as his eyelids drooped heavily. The storm raged on outside, but he felt safe here, nestled between the two people who loved him most.

Within minutes, his quiet, steady breaths told them he was asleep, his tiny fingers still curled around Y/N’s nightshirt, his stuffed stag tucked under his chin.

Regulus let out a contented sigh, tightening his hold on both of them before whispering, “He’s ours, isn’t he?”

Y/N smiled, pressing a soft kiss to Harry’s head. “Always,” she whispered back.

As the storm continued outside, their little family slept peacefully, wrapped in warmth, love, and the quiet promise of safety.

As usual, you quietly slipped out of your shared bed, careful not to disturb Regulus, who was a notoriously light sleeper. The hardest part was always getting in and out of bed without making a sound. You tiptoed your way to the kitchen, opened the fridge, and smiled at the sight of the leftover pasta Regulus had made earlier. He was an excellent cook, and his pasta was one of your favorites.

After piling some onto a plate, you popped it into the microwave. You were a pro at midnight snacking, always stopping the microwave just before the loud beep betrayed your secret. Except tonight, something went wrong.

The beep sounded, sharp and intrusive, slicing through the stillness of the night like a wand's hex. You froze, eyes wide, hoping against hope that Regulus hadn’t heard it. But before you could even take a breath, you heard the soft shuffle of footsteps approaching the kitchen.

Regulus appeared in the doorway, his hair mussed and a sleepy frown on his face. “Care to explain why my microwave is having a conversation with the entire flat at—” he glanced at the clock on the wall, “—three in the morning?”

Caught in the act, you froze with your hand still on the plate, a sheepish smile creeping onto your face. "I was hungry," you murmured, your tone equal parts innocent and apologetic, though you knew that wouldn’t fully appease him.

Regulus stood in the doorway, arms crossed and eyes half-lidded with sleep, though his expression carried more curiosity than anger. His tousled hair framed his face, and the way he leaned against the doorframe made it clear he wasn’t about to let this go. "Hungry? At three in the morning?" he asked, arching an eyebrow. "You couldn’t wait a few more hours until breakfast?"

You shifted awkwardly, twirling the fork in your hand. "Well... waiting didn’t seem like the best option," you admitted, avoiding his gaze. "And... this isn’t exactly new."

His eyebrow climbed higher. "Not new?"

With a resigned sigh, you gestured vaguely toward the fridge. "I’ve been doing this since we moved in. I just—well, I’m usually better at not getting caught. Tonight was... a fluke."

Regulus blinked at you, his expression unreadable for a long moment. Then, to your surprise, a slow smirk curved his lips. "So, let me get this straight," he said, his voice tinged with amusement. "You’ve been sneaking into the kitchen, raiding the leftovers, and using my microwave for your late-night escapades—all without me noticing—until tonight?"

You nodded, shoving a forkful of pasta into your mouth to buy yourself time. Maybe if you didn’t say anything else, he’d let it go.

Instead, Regulus sighed, the sound somewhere between exasperation and reluctant amusement. "You know, most people would just have a proper dinner instead of sneaking around like a thief in their own home."

"I did have dinner!" you protested, swallowing quickly. "I just—didn’t have enough. And your cooking is too good to resist."

He gave you a skeptical look but didn’t argue. Instead, he pushed off the doorframe, walked over to the counter, and grabbed a second fork from the drawer. "Well, you’ve ruined my sleep now," he said, sitting down across from you and helping himself to the pasta on your plate.

You stared at him, baffled. "Wait, you’re not mad?"

"Mad?" He gave you a look that was almost offended by the suggestion. "No. A little annoyed that you didn’t think to wake me up for midnight snacks sooner, maybe. But mad? Not really."

You blinked. "Why would I wake you up? You’d complain."

"Of course I’d complain," he said, his smirk growing. "But I’d still come. Midnight snacks are always better with company."

You laughed, the tension easing as you watched him steal another bite of your pasta. "You’re ridiculous, you know that?"

"And you’re lucky I’m such a tolerant flatmate," he shot back, raising an eyebrow at you. "Otherwise, I might have hexed the microwave by now."

You rolled your eyes, grinning. "Fine. Next time, I’ll wake you. But only if you promise not to steal all the food."

"No promises," Regulus said, twirling another forkful of pasta. "But you’re welcome to try."

As the two of you shared the stolen leftovers, the quiet of the flat felt warmer, cozier. Maybe midnight snacks were better with company after all. Or maybe, you thought with a smirk, it was just the challenge of not getting caught that made it so fun.

Guys I just fell into a rabbit hole of Timothée Chalamet fanfics early in the morning !

hidden in plain sight 🌟 - Y/N has always struggled with insecurity, convinced that someone like Regulus Black could never notice her. Little does she know, he hasn’t stopped talking about her for weeks.

Where you are 🪐- Regulus knew he wouldn’t survive, but he didn’t mind. Death meant seeing you again.

Regulus is definitely one of those people who get barked at.

TRUTHHHH UGHHH 😭😭😭😭

One thing golden era Wattpad writers had going for them was that they knew the importance of a buildup. I'm of the opinion that the sexual tension is WAY more satisfying to read than the actual sex and quite frankly there is a serious lack of non smutty writing.

Like I really miss reading fics/ x readers that start from scratch. Meeting the characters, initial reactions getting to know them, the tension the jealousy the TENSION the freaking tension.

Looking and looking away when they get spotted, touches that feel like they linger but perhaps they didn't and they're both so hot for each other that they think it's wishful thinking. And I don't mean just sweet sunshine romances, darker works can have a buildup too but it seems like so much is just about getting to the smut instead of the psychological aspect.

Bring back the build up!!!!!!!
