‘’Are you planning on getting up today or what, Y/N? You‘re going to be late if you don’t hurry.’’ Y/N slowly opened her eyes. ‘’What? What time is it?’’ ‘’Time for you to get your butt out of bed, come on Y/N.’’ ‘’Alright, alright, I‘m coming.’’ Y/N got out of bed and stumbled over to her dresser, got dressed and rushed to the bathroom. Then she remembered what day it was. Halloween. A smile formed on her lips. This was going to be an exciting day. When she was ready, she went downstairs to the common room, where Lily was already waiting for her. ‘’Finally! What took you so long?’’ ‘’Shut up, it's not like you’ve never slept in before.’’ ‘’Actually, I haven't.’’ Y/N rolled her eyes at her best friend's annoying comment and they made their way to the Great Hall to get some breakfast.
James and the rest of the guys arrived a couple minutes later, all of them with mischievous grins plastered on their faces. As they were walking by tye table Y/N and Lily were sitting at, Sirius shot Y/N a knowing smile. ‘'What's that all about?’’ Lily asked, but was only met with silence. Y/N was too preoccupied blushing and smiling at Sirius’ actions and seemed like she was deep in thought. ‘’Hello? Earth to Y/N? Anyone home?’’ ‘’Huh? Home where? What are you talking about, Lily?’’ ‘’Nothing, I was just wondering why your brother and his annoying friends are in such a dipper mood today, but I can see that you're too busy drooling over Sirius.’’ ‘’I was not drooling over Sirius! I was just thinking about something.’’ It was then that James gestured for Y/N to come over to their table. ‘’Hey, uhm sorry Lils. I have to talk to my brother real quick. I'll be right back okay?’’ Before Lily even got a chance to reply, Y/N had already gotten up from her seat and begun making her way over to James. ‘’What is it, James? I hope it's important, Lily is already suspicious enough without us overtly conspiring in the middle of the Great Hall.’’ ‘’A good morning to you to, sweetheart.’’ Sirius said while cleaning an apple on his robe. ‘’Anyways, just thought I'd let you know that there was a change of plans. We decided to go with the other spiders. Sirius made a good point about how they are actually way scarier.’’ James explained. ‘’What, but why? I thought we had agreed on the thin ones?’’ Y/N replied, obviously annoyed. She had gotten the spell down to perfection. ‘’Don't worry, sweetheart. The spell is almost the same and I'm sure you'll have it down in no time.’’ Sirius said with a charming smile on his lips. Remus raised an eyebrow at him, but no one seemed to notice. ‘’Yeah, okay, whatever. I’ll see you in the corridor that leads to Slughorn's office after lunch then. No more last minute changes of plan, okay?’’ Everyone nodded and Y/N made her way back to her table.
Five more minutes before lunch. Y/N kept glancing at the clock hanging behind Professor McGonagall's head. She was starting to get extremely nervous now. What if something went wrong? What if Peter somehow managed to screw the whole thing up? Wouldn't be the first time he messed up a supposedly fool-proof plan. She was quiet all through lunch and when the time finally came, she felt sick to her stomach. She had never pulled a prank like this before. On a professor of all people. They could actually get expelled for this. It's not like she had a problem with professor Slughorn, but even Y/N had to admit that his little exclusive circle was a bit too elite for her liking. He had asked her and James to be a part of it as well, but they had declined. Y/N was walking up the stairs to the corridor where she would meet up with Sirius and she could feel her heart beating faster and faster with every advancing step she took. Given that they were going to be hiding in one of the secret hiding places while the rest of the plan was going into action, they would actually not get to see most of the prank play out. From where they would be hiding they were just close enough to professor Slughorns' office to hear his reaction. Y/N rounded the corner and saw an overly excited Sirius pretending to casually walk up and down the hallway. Sirius smiled when he saw Y/N coming and turned around to make sure no one would see the two of them entering the office. The second Y/N reached the door, the snuck in and gently closed it. ''Alright. Are you ready to do this?'' he asked, the excitement clear in his voice. ''I guess, although I didn't love that last minute switch. It kind of threw me off a little bit. I thought we had agreed on the spiders.'' she said in an accusing tone. ''I know, I'm sorry about that. I just want this to go perfectly okay?'' ''I know. We should get started though, before we get caught.'' ''Slughorn won't be here for at least another hour, Y/N. No reason to worry. Alright, let's do this.'' Y/N and Sirius started filling the entire room up with fat, disgusting-looking spiders. When the room was almost full, they decided they were done and were about to leave when they heard noises outside the door. They looked at each other with panic and frantically started searching for a hiding place. Seconds before the door opened, Sirius pulled Y/N into one of the closets in the corner of the office and shut the door. Y/N had never breathed so quietly. Professor Slughorn had met Lily in the hallway and she had asked him about a book she wanted to borrow from him, so he had come back to his office to give it to her. When he entered the room, hundreds of spiders were crawling all over his desk, chair, portraits and anything and everything else that was in there. Lily, who had come in right behind him let out a shriek. ''What in the heavens happened in here?'' Professor Slughorn exclaimed. ''Some sick prank I assume, word must have gotten out about how much I dislike spiders.'' While Professor Slughorn pulled a disgusted face at the many spiders that were now occupying his office, Y/N and Sirius were squished against one another in the closet. Suddenly, Sirius saw something in the corner of his eye, right next to Y/N face was a massive spider with thick, long legs. He knew he had to distract her, or she would freak out. While he was trying to get her attention as quietly as possible, Professor Slughorn sent Lily to check the corridors for the person who might have done this. He assumed that they could not have gotten far, since he had just left his office about 5 minutes ago. He was just about to leave in order to look for the perpetrator himself, when Y/N noticed the gigantic spider. Lily's shriek had been nothing in comparison to Y/N's. With a wave of his wand, Professor Slughorn had opened the doors of the closet and it was all over. Sirius and Y/N were ordered to McGonagall's office and neither of them said a word on their way there, nor while they received the biggest lecture McGonagall had ever given. After an hour of having been screamed at, Y/N and Sirius finally got to go back to their dorms. They had each lost Gryffindor 40 points and got detention every day until the beginning of christmas break. When they finally got to the Gryffindor common room, they were greeted by a room full of angry Gryffindors. They quickly made their way over to the rest of their group. ''So eh, how did it go?'' Sirius said with an awkward smile. ''Better than yours I'd say.'' James said with a mocking tone. ''Wait, did you guys actually pull it off?'' Sirius asked. ''No, Lily caught us just in time to tell us that you guys got caught and told us to stop whatever we were planning on doing. They would've immediately known it was us.'' James explained. ''Wow, who would've thought Little Miss Evans would care enough about you guys to warn you.'' Sirius said. ''Actually, I really don't. I just didn't want Gryffindor to lose any more points than they were going to be taking from Y/N and Sirius. Anyways, you're welcome. Now if you excuse me, I have homework to do.'' Lily said, having overheard the last part of their conversation. ''Hey Lils, wait. I'll come with you.'' Y/N said, but Lily started storming off. ''Don't bother Y/N I've had enough of you for today. I'll just do my homework by myself tonight, if you don't mind.'' ''Oh eh, okay. Yeah. Sure, sorry. See you later then, I guess.'' Y/N's heart sank. She never meant for Lily to get mad at her because of this. The boys all gave her sympathetic smiles and offered Y/N to hang out with them instead. ''Sure, I don't really have anywhere else to be anyways.'' Y/N said with a shrug. ''Thanks, we enjoy hanging out with you as well, little sister. Good to know you appreciate our company.'' James teased Y/N and nudged her arm. ''Come on guys, let's go upstairs. I don't think we're particularly welcome here tonight. And also, besides losing Gryffindor 80 points, what else did you get. I'm surprised McGonagall didn't immediately expel you.'' James asked while motioning everyone to follow him upstairs. They spent the last couple of hours sitting on their bedroom floor talking and laughing about their failed prank and how much it sucked that Y/N and Sirius were going to be spending almost all of their free time in detention for the rest of the time leading up to christmas. When Y/N finally crawled into bed, it was way past midnight and Lily was already fast asleep. Or at least pretending to be.
