Hi! I altered your request just a little bit, I hope that’s alright. If you want me to fix anything or write you something else, just let me know. I hope you enjoy it!

(Warnings: swearing, let me know if i missed anything)

“I am so bloody sick of their pranks,” Lily groaned, marching into the dorms. You put down your book, sitting up.

You gave her a sympathetic smile, patting the spot on your bed next to you for her to come sit. “What did they do this time?”

“I just finished transfiguring a few of the second year’s faces and hair back to normal. They were nearly in tears when I found them downstairs. Apparently, Remus found a way to charm jellybeans into a form of polyjuice. Their hair was as white as Dumbledore’s. How they managed to get one of his hairs, I’ll never know.”

“They played that prank on Sirius last week,” you laughed, remembering the tantrum he threw when he couldn’t fix it himself. “It took me ages to figure out how to reverse it. I have to commend Remus on his brewing ability.”

Lily groaned, clearly not sharing your idea of humor on the matter. “I’m a prefect, you know. I can’t always turn a blind eye.”

“Who’s idea was it to use the jellybeans? I thought Remus just used it to get back at Sirius for nicking his chocolate stash.”

“I managed to crack James,” she said, rolling her eyes. “Apparently, it was meant for the Slytherins. There was some kind of mixup, and the second years got a hold of them before they could stop it.”

“Morons,” you mused, shaking your head.

“We need to get them back. They’ve gotten a little out of hand lately, and I don’t fancy being the subject of their next joke.”

You grinned, rubbing your hands together. “What do you have in mind? I’ve got plenty of ideas personally, but I’m open to yours.”

“Think about pranking your boyfriend often?” She asked grinning, her brow raised.

“You think I’m safe just because I’m dating him?” You asked, chuckling. “Even I am not immune to his little games. It pays to be one step ahead.”

Lily sighed, taking your hand in hers. “We’ll have to just come up with something good, then. It’s the full moon in two days, you know.”

“What does that have to do with anything?” You asked, turning your body to face her. “Remus will be preoccupied all day, I assume the boys will be as well. You know how he gets the day before, they’ll probably stick to the dorms so he doesn’t have to exert himself much.”

“Exactly.”

You furrowed your brows in confusion. “What’s your plan?”

You knew that Remus was a werewolf, as did Lily.

It didn’t take long for either of you to figure it out, and Remus reluctantly told you the truth when you confronted him about it and promised you would never tell. You had even offered to swear an Unbreakable Vow, but he declined. You resigned to letting the boys fill you in on what happened when Remus would return to their dorms, knowing they’d be the ones he turned to if he needed someone.

Lily knew that you were an Animagus, too.

She was the one you came to when you began training for it. Each month when Remus would return from the hospital wing, you’d cringe at the sight of his fresh scars. You wondered if there was a way you could help him, beyond brewing Essence of Dittany and visiting him the morning after. There had to be a way you could help him each transformation, something you could do in the moment, and not after. The thought led you to your training, which you eventually had to confide in Lily about so that she could help you.

Surprisingly, she was very helpful about it. She did scold you, and berate you about how dangerous and not to mention illegal it was. But she wanted to help Remus, too, so she agreed to help you.

What you didn’t know was that the boys beat you to the idea. They had already begun accompanying Remus on full moons, a fact that Lily discovered for herself. She was just that clever, putting together the pieces before anyone else.

The nicknames they openly called themselves may have had something to do with that.

The boys becoming Animagi probably eased her reaction when she discovered you were also training to become one. She had by then done some research on the topic herself, helping you with the final stages.

Together, you finished the trials, and you finally took the form of a wolf. Ironic, considering what had inspired you to begin training in the first place. You had yet to follow Remus to the Shrieking Shack on a full moon, figuring going alone probably wasn’t the best idea. You hadn’t quite figured out how to tell him or your friends about it, figuring they would think the idea was insane.

It was a wonder they had somehow managed to hide the fact from you that they had already done it themselves. You’d figure it out later, and have the opportunity to scold your friends and your boyfriend for not including you.

But for now, Lily was the only one who knew the whole truth.

And she would use it to her advantage. What better way to get back at her friends would there be, than to scare the shit out of them in their own dorm?

“I have a plan,” she smirked, giving you an uneasy feeling. “Not on the full moon, of course. I’m not reckless in the way they have been recently. But if they have a wolf, I think it’s time we use ours.”

Your eyes widened at her words, and you shook your head. “Are you mad? You want me to show the boys that I can turn into a wolf at will? Don’t you think they’ll wonder where I learned how to do that?”

“Oh, come on. There’s no harm in it. They won’t tell anyone, I promise. I wouldn’t suggest it if I thought they would react badly. Trust me on this.”

“Are you sure?” You sighed, your voice less than confident. “I’m not so sure Sirius will fancy the idea of his girlfriend turning into a giant beast.”

Lily grinned, disagreeing. “I have a feeling he’ll be very open to the idea. You practically have him on a leash. Where you go, he follows. It’ll be fine.”

You missed how she tried not to laugh at her own joke, and you stood, finally agreeing.

“Alright! How do we do this? Alone, right? I’d prefer scaring the shit out of them without other people seeing.”

“Tomorrow night, just after dinner starts. We go eat, and hurry back here before them. We’ll say you aren’t feeling well or something, and tell Sirius you’ll wait for him in his room. Their dorm will be empty, I’ll make sure of it, and they’ll be the only ones coming back so early. You sneak in and wait for them, I’ll come down and make a big fuss. They’ll rush up, and you scare them. Easy enough, right?”

You looked at her warily, both impressed and terrified by her plan. “You’re fucking scary, you know that? I’d hate to see what you and those idiots could come up with if you put your mind to it. It’s a good thing you don’t ever join them.”

“Never have, and I never will,” she mused, grinning at you. “But I’ll join you. It’s about time they got a taste of their own medicine.”

—

The next evening, as planned, you excused yourself from dinner. You made sure Remus’s plate was loaded up so that he ate enough to keep his strength up, and then you stood, pressing a kiss to the top of Sirius’s head.

“I think I’m gonna go lie down a bit,” you said, smoothing your hand over his hair.

Sirius turned around, looking concerned. “Are you alright, love?”

You smiled, reassuring him. “I’m fine. Just a little tired. Mind if I lay down in your dorm for a bit? Some of the girls are in mine and they’re always quite loud after dinner.”

He nodded, running a comforting hand up and down your arm. “Of course, darling. Do you want me to come up with you?”

Your eyes softened as you looked down at him, almost regretting the prank you were about to pull. But as your eyes met Lily’s, she reminded you of the plan, and you shook off the feeling.

“No, it’s fine, stay and eat,” you said, squeezing his shoulder. “Lily, would you mind coming with me, though? I wanted to ask about the Potions lesson today, I think I missed some of the notes.”

Lily nodded, standing up. “I’m finished anyways. Come along, darling.”

She linked her arm with yours, leading you away from the table and out of the Great Hall. As soon as you were out of sight, you snickered together, rushing for the dorms.

“Get up there quickly,” she said, ushering you through the portrait entrance. “Sirius seems rather worried about you, the lovesick git. He chooses now to be a good boyfriend?”

“He‘s always a good boyfriend,” you laughed, heading up the stairs to the boys dorm.

“Yes,” she agreed, playfully rolling her eyes. “It’s sickening at times. Now hurry up, before he decides to come back and do something sweet and ruin it all.”

You nodded, quickly pushing open the door to the boys dorm, closing the door behind Lily. You looked around the room once you both were in, and Lily’s eyes widened in shock.

“Merlin, they’re messy,” Lily gasped, bending down to pick up stray items of clothing and pieces of parchment.

You snickered as she tried to clean. “I’d be careful what you touch, love. You don't know where all this shit has been.”

She grimaced, quickly dropping everything in her hands. She took her wand out of her pocket, casting a cleaning spell. You watched as everything on the floor hovered in the air, before categorizing itself either onto a bed, bag, or in the bin.

“I casted a listening charm in the common room, we’ll be able to hear when they come in.”

“I’d probably be able to hear it, anyways. Wolf hearing and all,” you thought out loud.

Lily nodded, turning to you. “Alright, let’s see it. Do your thing.”

“Where do you want me?”

Lily thought a moment, before shrugging. “It doesn’t matter, I don’t think. A wolf in any part of their room will freak them out…although maybe you should sit on James’s bed. Something tells me he’d scream the loudest.”

You laughed, nodding. “See you in a bit, then.”

Without another word, you shifted into your wolf form, now on four legs. You stood tall, bowing to stretch as you got used to being in this form.

Lily nearly gasped when you finished, looking at you with wide eyes. “I nearly forgot how big you are like that. Of course you’re black, too. You match your boyfriend. Why am I surprised?”

You huffed, jumping up on Sirius’s bed. You sat on the edge of it, laying down. Lily came over to stand next to you, running a hand along the fur on your spine.

“You really are scary, you know. I think James is going to cry.”

You wished you could laugh, turning to nuzzle your head into her hand. Suddenly, Lily perked up, heading to the door.

“They’re coming! Get down, stand right here behind the door. I’ll corral them all in here, and shut the door so they can’t get out. Do try to not get hexed, I’ll do my best to make sure that doesn’t happen. Be right back!”

She opened the door, feigning terror. She let out a scream, bounding down the stairs.

“James!” You could hear her call. “Sirius, Remus! Someone help!”

“What is it?” A unison of voices said, and then there were footsteps bounding up the stairs.

You took the sound as your cue to hide, stepping behind the door so you couldn’t be seen at first. The door was pushed open, and one by one, the boys filed in. They all stopped in their tracks, looking at each other confused. Lily closed the door behind them, standing against it so they couldn’t leave.

“Lily, there’s nothing in he—“

Remus was cut off by a low growl, and the boys turned to see you stalk closer to them from the side of the room. James let out a yelp, clambering to climb up onto his bed.

“What the fuck?” James screamed, nearly shaking on the bed. “It’s humongous.”

“Is that…that’s a…it’s a…,” Sirius stuttered, before Remus grabbed his shoulder, pulling him behind him.

“A wolf.”

“A werewolf or a wolf wolf?” James asked, and Sirius scoffed from behind Remus.

“Don’t be daft, James. Werewolves can’t just turn at will, not like this. And it’s not a full moon yet.”

“That’s not what I look like is it?” Remus asked, looking down at you cautiously.

“Where’s Y/N?” Sirius asked, frantically looking around. “Wasn’t she up here with you?”

You had yet to move, looking between your friends. From the door, Lily was trying to hide her snickers. You huffed out a breath, taking a slow step forward. All three boys let out a squeal, stepping back.

Lily rolled her eyes, taking a step towards you. “Not very brave, for a bunch of Gryffindors.”

“Lily, no!” James yelled, jumping down from the bed. You let out a growl at him, making him hesitate. He tried to step forward again, but Sirius held an arm out across his chest, holding him back.

“Sirius!” James argued, but Sirius wouldn’t relent.

“Just wait!” Sirius said, looking at you with curious eyes. “Evans…keep going.”

Lily nodded, slowly approaching you with an extended hand. You feigned interest, sniffing her hand. After a minute, you nuzzled her hand with your snout. She let out a giggle, running her hand through your hair, reaching up to scratch behind your ears.

“Is Lily petting a fucking wolf?” Remus asked, looking back at his friends. “Am I going mad?”

“If you’re mad, then I’m batshit crazy for this,” Sirius said, slowly approaching you. “Please don’t bite me, please don’t bite me…”

His voice trailed off as he crouched down in front of you, letting you sniff his hand. He avoided your gaze, his hand slightly shaking with fear. You decided you had stalled long enough, flexing your paws. Suddenly, you leaped, landing on Sirius and knocking him to the ground. You pinned him to the floor under you, hovering your face just above his.

“Fuck!” Remus said, reaching for his wand.

James had already drawn his, moving to stun you, when Lily stood in between you and them to block you.

“Don’t!” She said, drawing her own wand. “Don’t hurt it.”

“Are you mad? It’s on top of Sirius right now, move,” Remus said, trying to reach around her. “Lily, this isn’t funny.”

“If we aren’t going to do something about it ourselves, then we need help. I’m going to get a professor,” James said, headed for the door.

“No need, boys,” Sirius called up from the floor. “I think I’ve got it handled.”

Lily moved out of the way to reveal Sirius on the floor, with you resting flat against his chest. The boys looked at him stunned, and Sirius was reluctant to move under you.

“We may need a professor to help get you out,” Sirius said, smoothing a hand down your fur. “But I think it’s safe to say you aren’t going to kill me.”

Lily whistled, and you climbed off Sirius’s chest, moving to stand beside her. She gave you a look, and you took that as a sign, slowly shifting back into your regular form. You stretched once fully stood, smoothing down your clothes.

Sirius gaped up at you from the floor. “Y/N?”

“What the fuck is going on?” James asked, pushing his way out from behind Remus. “How did you do that?”

“She’s an Animagus,” Remus realized, nearly grinning. “And a wolf. Ironic, isn’t it? Should I feel flattered, Y/N? Do you love me?”

He drew out the ‘o’ in love, making you laugh. Sirius looked between the two of you with wide eyes, flustered. You cooed at him, reaching for his hand. He begrudgingly let you take it.

“I hate to disappoint you, Remus, but I’m not in love with you. I am loyal to you, though. A bit protective. I suppose that had something to do with it. I didn’t choose my form, you know. It just happened. It’s like a patronus.”

Lily let out a small gasp, smirking in realization as she looked at Sirius. “Sirius…the wolf is akin to the dog, is it not? I wonder what your thoughts are on the matter.”

James visibly paled, trying and failing to hide his shock as he put the pieces together. Lily knew. But how?

Sirius was beginning to wonder the same thing. “James, you dickhead! Why’d you tell her?”

“I didn’t tell her anything!” James exclaimed, raising his hands in surrender. “I don’t know how she knows!”

You looked between your friends with a confused look on your face, piping in. “Know what? What’s going on?”

“You figured it out, didn’t you?” Remus smirked, interrupting the bickering between the boys. “Nicely done, Evans.”

“Thank you,” she curtsied, grinning at the confused look on the rest of her friends' faces.

It was your turn to figure it out as your eyes widened in shock. “Holy shit! You’re all Animagi, too. How didn’t I figure that out sooner? It’s obvious, now that I’m thinking about it.”

“I didn’t know you were one,” James said, shrugging. “I don’t think it was that obvious.”

“That’s because you can’t keep your eyes off Lily long enough to notice much of anything,” you mused, making your friends snicker.

“Alright, I think that was a success,” Lily said, clapping her hands together. “Let’s go, boys. I’ll explain the rest.”

James and Remus nodded, heading for the door. Lily gave you a smile, following them as they filed out. You could hear her teasing James, stifling a laugh while he was still in earshot.

“That scream was truly something. How very valiant of you, James,” Lily said, smirking. “My hero.”

James groaned, the sound of his voice quieting down the further away he got. “Forgive me for not jumping into action at the sight of a fucking wolf in my room.”

You shut the door as their voices drifted away, turning back to Sirius. You narrowed your eyes at him, slapping him across the arm.

“What was that for?” He whined, clutching his arm.

“For not telling me you’re an Animagus!”

“You didn’t tell me you’re one, either,” he pouted, still rubbing at his arm.

“Don’t be a baby,” you said, rolling your eyes before bending down to place a quick kiss to the spot you hit. “I didn’t tell you because I haven’t worked up to going outside yet. You’ve all been going with Remus for months, haven’t you?”

Sirius gave you a sheepish look, nodding.

You groaned, shaking your head. “Your form is a dog, I suppose? I guess the nickname Padfoot is actually clever, then.”

“It is a dog. Ironic, I know. When did you start training?”

You thought for a moment, pondering. “A few months. Three, maybe?”

“Smart girl. It took me six,” he said, grinning. “I’m flattered, by the way.”

You furrowed your brows at his words. “Flattered?”

“Your form matches mine, you took after me since mine was established first. It isn’t because you’re loyal to a wolf, and therefore a wolf yourself. It’s because you’re loyal to me. We’re alike.”

You could feel yourself flush at his words, smiling. “So, you saw me. Do I get to see you?”

Sirius grinned, before quickly shifting into his form. You smiled as a wiry black shaggy dog appeared in front of you, with fur as unruly as Sirius’s hair could be. Padfoot was quite adorable, but also slightly terrifying. You had that in common.

You ran a hand along his fur, noting the black sheen of his coat. “We match.”

Sirius shifted back into himself, taking a seat on his bed. He held a hand out for you, pulling you to sit beside him.

“You might be cuter as a dog,” you mused.

He playfully nudged you in the ribs, shaking his head. “You’re insufferable, darling.”

“Hush,” you said, grinning at him before grabbing his hand. “You told James to stop. You let Lily approach me, having no idea whether she’d be attacked or not. Why?”

He was quiet for a moment, scanning your face as he gave you a small smile. “Your eyes.”

“What?”

“You have the same eyes as the wolf. I could see you in them.”

You smiled at him, pressing a kiss to his shoulder as you squeezed his hand. He squeezed back, letting his head rest against your shoulder.

“We’re gonna have to come up with a nickname for you," he murmured. “I suppose you’re going to want to come with us on full moons now, aren’t you?

You chuckled, nodding. “You won’t be able to stop me, love.”
