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.

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.
