warnings: sweetheart!reader, r is shy and anxious, r is best friends with regulus and barty, animagus transformation, magic, snow, fluff, panic and anxiety, seasonal cold/snow, mild self-doubt, feelings of nervousness and vulnerability.
You stand nervously in the middle of the snow, your breath rising in small clouds as it meets the crisp winter air. Every nerve in your body feels alive, tingling with anticipation and fear.
Pandora and Regulus are both staring at you, their expressions calm but attentive, while you panic and spiral quietly to yourself.
Your thoughts feel heavy, though you are still very much yourself, very much human, in this moment.
“It is completely normal to feel nervous during your first transformation,” Pandora says gently, kneeling slightly in the snow to be closer to your level.
“Especially when you do not even know what your Animagus will be.”
You shake your head, panic prickling in your chest. “I… I don’t know if I can do this,” you admit, your voice trembling. Your hands fidget with the cuff of your sleeve. “What if I fail? What if I hurt myself?”
Regulus steps a little closer, his hands shoved into the pockets of his coat, his expression composed yet firm. “You will not hurt yourself,” he says, his voice low, carrying a quiet certainty. “I know you. You are careful, and precise. Even your first attempt will not be dangerous.”
Your eyes widen as worry twists in your stomach. “But what if my Animagus is dangerous? What if it is something wild or… I don’t know… something I cannot control?”
Regulus lets out a short, amused chuckle. “You are my best friend. You would not be capable of producing anything dangerous. And honestly, I would not be surprised if it turns out to be something completely harmless. Likea butterfly.”
You pout, shoulders tense, feeling a little relief at his attempt at humor but still trembling. “I don’t know how to transform. What if I just… cannot do it?”
Pandora opens her notebook carefully, the pages crisp against the cold air. “Don’t worry,” she says, flipping to the page she has marked.
“We will go through the instructions step by step. Focus on your breathing. Relax your muscles. Visualize the form you wish to take. Imagine every part of your body shifting, folding, and changing until it feels natural.”
Regulus crouches slightly beside you, watching you carefully, his dark eyes bright with encouragement.
“The first time I transformed,” he says, a faint grin tugging at his lips, “I became a cat. Tiny, soft, and like a black shadow. I hid under the couch for hours because I was terrified I would break something or scare someone. But I learned to control it. You will, too. It is just a matter of patience and practice.”
You bite your lip, your gaze dropping to the untouched snow beneath your feet. “It still feels… impossible.”
Pandora reaches out and gently rests a hand near your shoulder, careful not to startle you. “Nothing worth doing comes without some fear. It is natural. The important part is that you try. That you don’t give up on yourself before you even begin.”
Regulus leans a little closer, lowering his voice to something almost conspiratorial. “I will be right here watching and making sure nothing goes wrong. I promise. And if it does… well, we will handle it together.”
You take a deep breath, feeling the crisp winter air fill your lungs, and step carefully back onto the thin ice near the edge of the frozen stream. You pull your scarf tighter, though it is heavy and awkward against your suddenly smaller frame.
Pandora kneels a few steps away, her notebook still in her hands. She tilts her head slightly, watching you with gentle patience. “Remember the steps,” she says softly.
“Relax. Focus. Visualize. You have worked for months for this. You can do it.”
You tense your muscles, every fiber of your body trembling, and let the magic flow. It begins at your toes, a strange tickling warmth that moves up your legs.
The sensation is dizzying, surreal, like every bone and muscle is bending in impossible ways. Your heart pounds, and you stumble on the ice, flailing slightly before your hooves catch.
When the shift is over, you stare down. Your hooves press into the snow, delicate and firm. Your legs feel both fragile and alive. You take a small, tentative step and then another, testing balance and coordination.
The cold snow presses against your fur, sparkling on the tips of your coat.
You flick your ears nervously, eyes wide, and glance toward Pandora and Regulus.
Their reactions hit you like a shock. Pandora gasps softly. “Oh… my…” Her eyes are wide, full of awe.
Regulus steps closer, a small smirk tugging at the corner of his mouth, though his voice carries a quiet wonder. “Incredible,” he says, crouching slightly.
Your tail flicks nervously, and you back up a few steps toward the frozen stream. You pause at the edge and lower your head toward the ice, sniffing, trying to understand yourself in this body.
The reflection that stares back at you makes your chest tighten with disbelief. Small, wide eyes, soft brown fur, and delicate white spots across your back.
A little deer.
You paw at the snow, testing your legs, and take a careful step forward, then another, discovering the agility in your new form.
Pandora tilts her head, eyes widening with so much joy that she practically glows. Her breath bursts out in a delighted cloud as she claps both hands over her mouth.
“Oh my god, you are like a little fawn!” she squeals, bouncing on her toes as if she cannot contain the excitement. “Look at you! You are tiny and spotted and absolutely precious!”
She crouches down a little, leaning closer with shining eyes.
Regulus chuckles lightly, crouching so he is level with your eyes. “I would never have guessed, but it suits you.”
Your ears twitch at every sound—the whisper of the wind, the crunch of snow beneath Regulus’ boots, the distant caw of a bird.
A tiny, excited leap carries you forward, snow spraying around your hooves. Your movements are clumsy but joyful, and a little thrill of freedom surges through you.
Pandora claps her hands softly, and Regulus leans back, eyes bright with amusement and pride.
The snow, the forest, the cold, the magic;; it all feels like it is yours, in this moment, completely and beautifully yours.
The second you shift back into your human body, you stumble straight onto your knees in the snow. A rush of wild exhilaration bursts through your chest, so powerful you can barely breathe.
I did it!” you gasp, practically choking on your own smile. “I did it, I did it! Pandora, Regulus, did you see that?”
You don’t even wait for an answer. You throw yourself at Pandora so fast she lets out a startled squeal of laughter as she catches you.
“You did it, sweetheart!” she cries, gripping your shoulders and shaking you a little in excitement. “You were amazing! I knew you would get it!”
You shake with excitement and cling to her a moment longer before turning and launching yourself at Regulus.
He stands with his arms half-raised, pretending he is not expecting it, although his eyes soften the moment you collide with him.
“Regulus!” you gasp, grabbing the front of his coat and practically bouncing on your feet. “i was a deer—a real deer! with spots and hooves and everything!”
His arms come around you slowly, steady and grounding, as if he wants to hold onto your excitement without letting it overwhelm you. His voice is low, smooth, calm.
“I know,” he says. “I saw the entire thing.”
You pull back a little, cheeks flushed, breath quick. “Did I look strange? Did I look ridiculous?”
He tilts his head, meeting your worried gaze, and a small, almost imperceptible smile touches his lips. “No. You were amazing,” he says softly. “Even when if the transformation was a little sloppy, it was perfect. You handled it better than anyone could have expected.”
You cover your face with your hands, heart pounding, and he gently moves your fingers aside, brushing snow from your hair.
“But you were also adorable,” he adds quietly. “A very, very adorable deer.”
You couldn’t help but feel giddy on the inside at Regulus’s praise.
He may have been your best friend and closest companion, but it was rare for Regulus, of all people, to show any emotion at all—let alone let his pride seep through the cracks of his carefully maintained walls.
A word of praise from Reggie, meant the world to you. It made your chest feel lighter, your heart warmer, and every bit of hard work you’d poured into becoming an Animagus feel completely worth it.
Pandora laughs again, brushing snow off your sleeve. “You should be proud. What a beautiful Animagus form.”
Regulus steps back and lifts one eyebrow. “Well then. Off you go, amour. Go show your boyfriends before you burst from excitement.”
You gasp dramatically and clutch Pandora’s hands. “We have to go. I need to tell them right now.”
Pandora squeezes your hands with the same excitement. “Go. They will be thrilled.”
****
“James!” you call the moment you burst into the common room.
You don’t even wait for him to answer — you grab his wrist with both hands and start tugging. “Come on, come on, come on, I need to show you something!”
James barely has time to blink. “Merlin, love— what’s got into you?” He’s stumbling after you, curls bouncing, but he’s already smiling because you’re smiling.
“Sirius!” you call over your shoulder. “Remus! Get over here!”
A groan answers you from the couch. “It’s snowing,” Sirius complains, dramatically wrapping himself tighter in a blanket. “Do you know what snow does to my hair?”
“You’ll survive!” you say, breathless and glowing. “Please, Pads, it’s really— really— really important.”
Before Sirius can argue again, Remus appears from the hallway, book still in hand, scarf slung over his arm. He takes one look at you, practically vibrating with joy, and his whole expression softens.
He steps forward and gently cups your face with both cold hands. “Dovey,” he murmurs, brushing his thumb over your cheek, “take a breath. You’re shaking.”
“I know,” you say, grinning so hard your eyes crinkle. “I’m sorry— I just— it’s important, Moony.”
“No apologizing.” He smiles faintly. “Just slow down enough so we can keep up with you.”
“Right— right, okay,” you say, even though you’re still bouncing a little on your toes.
Sirius slinks over now, muttering under his breath, blanket still draped around him like a cape. “This better be worth frostbite.”
“It is,” you say, nearly squealing.
James squeezes your hand, brows raised in playful intrigue. “Are we going to pull a prank? Because if this is about causing some trouble, I’d like to mentally prepare first.”
“No! Well— no. Not this time.” You tug him closer. “It’s a surprise.”
Remus lets out a small, fond sigh and flicks his wand. Scarves whoosh out of his bag and wrap themselves neatly around each of your necks, warm as a cup of tea.
“If we’re going out,” he says, adjusting yours with gentle fingers, “we’re doing it without any of you getting sick.”
Sirius brightens immediately as the warmth hits him. “You should’ve led with the free winter gear,” he says, looping his scarf twice. “Very persuasive.”
“Alright,” James says, squeezing your shoulders, “where to, sweetheart?”
“Outside,” you say, practically glowing. “Hurry!”
Sirius opens the door with a flourish, snow drifting in on a soft, icy breeze.
You step into the center of the courtyard, breath puffing in front of you in little clouds. The boys stand a few feet away, bundled in their scarves, waiting.
But now that they’re actually here, watching you… your heart stutters. Nerves flutter in your stomach. You take a small step back.
Sirius tilts his head, a curious smile tugging on his lips.
“Come on, sweetheart,” he teases, “what is it you’re dying to show us?”
James laughs breathlessly. “Yeah, love, you’re scaring us a little.”
You swallow, nod once, inhale deeply—
And then you shift.
The world ripples around you, magic curling over your skin like warm light, and in a blink, you’re standing on four legs in the snow.
A small, soft deer with your fur dusted with flakes, breath steaming in the cold.
Three pairs of eyes widen dramatically.
For one perfect moment, silence.
Then—
James absolutely screams.
“Holy— Merlin’s scruffy stag— when— how— what—!”
James grabs Sirius’s arm, his eyes wide as if holding onto someone might help him process what he just saw.
Sirius stays frozen, mouth slightly open, completely still, like he can’t believe what he’s seeing.
Remus just blinks, taking a moment to register it all, his expression caught somewhere between shock and awe.
You stamp your little hooves impatiently, looking at them with wide, pleading eyes, as if to say, Well??
James is the first to find his voice, stumbling over words in his excitement.
“When did you even—how did you go through the Animagus process without us knowing— ”
You can’t help it. The thrill of it, the joy of finally revealing yourself, bubbles out uncontrollably, and you jump, bouncing in the snow, spinning and hopping with excitement.
And suddenly Remus breathes out a stunned laugh. “Oh, sweetheart— come here—”
You don’t even let him finish. You gallop straight toward him and tackle him into a soft drift of snow. He goes down with a yelp and then bursts into laughter, wrapping his arms around your warm neck.
“Okay— alright— alright— you’re heavy like this—” he wheezes, still grinning up at you. “Merlin, you’re beautiful.”
You nuzzle his cheek before prancing away, hooves crunching through the fresh layer of snow.
James is already crouched, eyes wide with pure awe and giddy pride.
“Look at you!” he gushes, one hand reaching out carefully to stroke between your ears. “You’re perfect. D’you know that? Absolutely perfect.”
You lick his sleeve and he laughs like a little kid.
Then you turn to Sirius.
He hasn’t moved at all.
He’s standing like someone hit him with Petrificus Totalus, except his eyes are huge and soft and the tips of his ears are pink from the cold.
You trot up to him and blink up at him with wide doe eyes.
He inhales sharply. “Oh… oh no,” he whispers. “You’re— you’re literally the cutest thing I’ve ever seen.”
He drops to his knees instantly, hands hovering like he’s afraid to break you.
“I have so many questions— so many— but I can’t think right now because your little face is attacking my soul.”
You poke his side with your velvety nose.
He giggles. “Oh, that’s illegal— don’t look at me like that— Bloody hell, you’re adorable—”
He finally wraps his arms around your neck, burying his face into your fur. “I’m never letting you be human again.”
You snort loudly, which makes him laugh even harder.
And then—
James shifts into his stag beside you, tall and magnificent, nudging your shoulder with a joyful snort.
Sirius rolls his eyes, stands up, and transforms in a smooth wave of magic — a huge black dog shaking snow from his fur.
You squeak (or… whatever the deer equivalent of a squeak is) and immediately bolt across the courtyard.
Prongs and Padfoot charge after you, hooves and paws thundering through the snow.
Remus stays human, arms crossed, scarf fluttering in the wind, laughing helplessly as you dart behind him for protection.
He places one steady hand on your back.
You press closer to Remus, hiding half behind him, peeking out just enough to flick your ears at the two troublemakers.
Remus laughs and pats your side.
“My brave girl,” he teases softly. “Hiding behind the man who can’t even shift.”
You nudge him indignantly.
Padfoot and Prongs are still waiting for another chase, but both of them stay where they are when Remus places one calming hand on your back.
“It’s alright,” he murmurs. “Take your time. Whenever you are ready.”
You close your eyes. The magic rises again, warm and familiar now, like sunlight curling through your limbs. Your shape shifts. Your hooves sink into the snow and dissolve. Your fur pulls inward. The world tilts once, gently, and then settles.
You are human again.
Your knees fold, and you collapse forward into Remus’s chest, breath coming out in a startled gasp.
His arms tighten instantly, closing around you with a fierceness that makes your heart swell.
Remus’s hand rests lightly on your back, his voice soft as he leans down. “You alright?”
You lift your head just enough to meet his gaze, still flushed and breathless, and nod. “Yeah.”
Then, with a little nervous grin, you stare up at him. “Soooo… what do you think?”
He lets out a quiet, fond chuckle, brushing a hand through your hair. “I think… you’re amazing.”
You peek up at him through the scarf, a little shy but still glowing with excitement. “You… really think so?”
“I do,” Remus says quietly, his thumb brushing over your cheek. “You were incredible. All of it. I’m proud of you.”
Your chest swells, and you can’t help the soft, delighted laugh that escapes you. “Thank you… I was so worried you’d think it was silly or—”
Before you can finish, a loud chorus breaks through the calm.
“There she is!” James cries, barreling through the snow toward you, his hair dusted with flakes, a grin plastered across his face.
“You have an unbelievable amount of explaining to do, darling,” he announces, although his voice is far too warm to be truly scolding.
You giggle and pull your scarf close, cheeks warm despite the cold. Remus keeps one arm wrapped firmly around you as if he refuses to let you go now that you are back in human form.
“I know,” you say, still breathless and glowing. “I know I should’ve told you sooner. I just… needed to be sure. I didn’t want to say anything until I knew it was real.”
James’ brows lift, but his eyes are nothing but warm. “So all of this… has been going on for a while, then?”
You nod, hands twisting together for a moment before you make yourself meet their eyes. “A little over a month. Pandora helped me with the theory — she’s brilliant, honestly — and she was so patient with me. Every single time I messed up, she just tried again with me.”
Sirius snorts softly, though his smile is fond. “Of course she did. Pandora Lovegood could teach a rock to dance if she felt like it.”
You laugh, cheeks warming. “And Regulus helped too with the practical pieces. Making sure I didn’t try anything too reckless. He’s… very steady. He kept me grounded.”
James hums under his breath, impressed. “So he knew before we did.”
“Only by an hour!” you say quickly, as if it matters. “Today was the first time anything actually worked. And as soon as it did, I ran straight here.”
That earns you three different smiles, all of them soft.
Sirius nudges your shoulder gently. “Good. Because seeing you turn into that little deer might be the cutest thing that has ever happened in my entire life.”
You hide your face in your hands for a second, which only makes James laugh and pull your hands back down so he can see you. “Hey,” he says softly, “none of that. We’re amazed. That’s all.”
Remus’ hand finds its place on your back, slow and steady, his touch radiating reassurance. “You did something incredibly difficult, love,” he murmurs. “And you did it beautifully.”
Your breath catches in your throat, not because of nerves this time, but because of how full your chest feels.
You end up pulled into all three of them at once, completely surrounded and impossibly warm despite the snow drifting around your boots.
James presses a kiss to your cheek. “I’m so proud of you.”
Remus tightens his hold just slightly, voice low against your ear. “We all are.”
Sirius rests his chin on your shoulder. “Our little Bambi,” he says with a grin you can hear.
You let out a tiny laugh, too flustered to hide it. “Bambi?”
James grins. “Well, we can’t exactly keep calling you dovey now that we know you’ve been prancing around the forest behind our backs.”
Remus leans in slightly, his breath warm against your temple. “So,” he murmurs, a subtle smile in his voice, “do you want us to stick with dovey… or should we be calling you Bambi now?”
Your cheeks warm immediately. You duck your head a little, trying not to smile too widely.
“I don’t know,” you say honestly, the words coming out softer than you intend. “Either one is fine.”
Sirius snorts lightly. “That’s not an answer.”
You laugh under your breath, nudging him with your shoulder. “I don’t have a preference,” you admit, eyes flicking between all three of them. “If it’s from you, I’ll like it.”
James’ smile softens, warm enough to melt the snow still clinging to your coat.
“Well then,” he murmurs, brushing a bit of snow from your hair, “come on, Bambi. Let’s get you inside before you freeze.”
