You giggled to yourself as you stirred the cauldron, placing the small tuff of hair you had somehow managed to take from Professor Sharp into the mixture, watching it change colours instantly. “This is going to be brilliant, Ominis!” You said, lifting your head to smile at Ominis, who shook his head as he tried to hide a smile. “I’d be surprised if you managed to make it ten minutes into this plan of yours, let alone into the hall.” You smiled as you poured the mixture into a cup, shaking your head in anticipation. “I’ll make it work; don’t you worry. Do we have everything here? Robes, items of interest, things like that?” You asked, watching Ominis nod as he pointed to where he had left what you requested. He had no idea how you managed to bring him into such a scheme, but there he was as he listened to you as you went through your plan, smirking when you brought up your endgame. “Sebastian’s not going to know what hit him, just you wait. I can see his face now; red, probably embarrassed, he won’t be able to look Sharp in the eye for weeks!” You giggled to yourself as thought about it, glancing over at Ominis to see him smile. “Bottoms up, I suppose.” With that, you tipped the cup to your lips and downed the liquid, gagging a bit at the sour taste. Ominis frowned as he listened to you react to the potion, glad that he was unable to witness the horror that would be you morphing into one of your teachers.
“That went better than expected.” Sharp’s voice echoed through the Undercroft, which startled Ominis for a quick moment. “Well, you certainly sound like him.” He breathed, a slight huff escaping him. You laughed; it felt unnatural to hear Sharps voice mimic your own, yet you couldn’t stop yourself from laughing more. “Now you sound like someone dosed Sharp with something. If you hope to get away with this, you need to act like the professor.” Ominis said, shaking his head. You finished changing your robe and grabbing what you needed from the floor, taking a breath as you tried to get into character. “Right, thank you for your helpful insight, Mr. Gaunt.” Ominis cleared his throat as he tried to hold back a laugh, shaking his head. “It’s unsettling how quickly you switched up, I have half the mind to believe that Sharp was here, if it wasn’t for the fact that I heard your voice a few minutes ago.” You frowned playfully as you took a few steps around, trying to match your gait with the professor’s before you headed out. “Do I sound like him when I walk, Ominis?” You asked, turning to walk over to him as he furrowed his brows. “It seems like you have his walk, I can only assume that to anyone else, you are the professor.” You smiled, moving to leave the Undercroft. “Perfect, I shall be back when my plan is done.” “I fear for anyone that comes in contact with you.”
You walked down the halls, speaking with a student every now and then as you searched for certain students, careful to avoid the actual Professor Sharp. You turned down a hall as you narrowed your eyes, landing on the head of Leander, who stood on the side as he spoke to some of his friends. Smiling to yourself, you walked over and stood behind him, raising a brow as you listened to him talk. You had arrived mid-conversation, and only caught Leander talking about some Slytherin students when his friends motioned for him to turn around. Leander looked up at you with wide eyes, the colour draining from his face. “Mr. Prewett.” You said, looking down at him. He frowned slightly as he tried to avoid your gaze. “Professor Sharp, hello.” You held your composure as you continued to look at him, raising an eyebrow. “Did you get some of that potion on you yesterday?” Leander furrowed his brows, unsure what to say. “The potion?” “Yes, the one that you claim, “Got stuck to your robe and fell over.” Did you get any on you?” Leander nodded slightly, cheeks heating up as he remembered potions class. “Yes sir, but why do you ask?” You smirked slightly as you looked to his friends as they tried to keep straight faces. “You smell horrible. Have you not changed your robes since yesterday?” Leander’s friends snickered behind him as his face grew redder. “No sir, I didn’t think that it would smell.” “It does, I suggest you fix it quickly before another professor gives you detention for being unhygienic.” You turned away from him and began walking away, smiling to yourself as you listened to Leander mutter to himself and sprint away to his dorm.
You continued down the halls as you searched for your final victim, who sat alone in the courtyard reading a book. You shook your hands slightly in excitement before you walked through the doors, walked right up to Sebastian. “Mr. Sallow, I’m glad I found you here.” You said, startling Sebastian as he looked up at you with wide eyes. “Professor? Were you looking for me?” You nodded as Sebastian stood and put his book into his bag, confused. “Indeed. I had some concerns after yesterday's Potions class that I thought I should address.” “Concerns?” Sebastian asked, frowning. You nodded, looking around the empty courtyard. “All by yourself today?” He nodded, still confused. “Rather unusual, given your closeness with Miss L/N and Mr. Gaunt.” You watched Sebastian closely as his cheeks heated slightly, shaking his head as he shrugged his shoulders. “They were busy, figured I could use some time alone to catch up on some reading.” You smirked as you nodded.
“My concerns from potions class pertain to your closeness with y/n. I have half the mind to separate you two, so you get your work done more efficiently. Can’t have you two distracting each other.” You said, turning away from Sebastian to hide the smile that fought its way to your lips. Sebastian stuttered, his face heating up more as he watched you in confusion. “I don’t understand. What do you mean by distracting?” You shook your head, trying to form a frown to fight your smirk. “I mean, Mr. Sallow, that I don’t want your girlfriend blowing herself up because you wanted to show-off.” You forced the frown to stay as you turned back to Sebastian. You watched his face become even more red as he tried to stutter out that you were not, in fact, his girlfriend. “Ah, so Miss l/n isn’t your girlfriend?” You asked, smirking at Sebastian as he shook his head frantically. “A word of advice then, Mr. Sallow. Become a better actor.” He looked up at you with furrowed brows, confused. “By that I mean, stop acting smitten with her. You have half the castle believing that you were together.” You turned again, fighting your smirk from becoming a big smile.
“I do not act like I’m…smitten!” Sebastian said, frowning in embarrassment. You shook your head as you looked back at him, raising an eyebrow. “Of course, my mistake. Another thing, however.” You reached into your pocket as your fingers grasped around the fabric as you smirked. “Perhaps you should keep better track of your clothing, as well.” You tossed the cloth to Sebastian, watching his thought narrow as he caught it. His eyes widened as his face grew hot, staring at the boxers that sat in his hands. “It’s rather weird to have your initials on your undergarments, but perhaps you deal with this problem often?” Sebastian stuttered as he watched you walk away in horror, unable to speak as he tried to make sense of what had just happened. You quickly walked down the halls as you made your escape, feeling the potion wear off as you hid in one of the off-limits restrooms. You laughed quietly to yourself as you changed back to your normal state, tears in your eyes as you replayed the events. You had to thank Ominis for the boxers when you returned.
You roamed the halls casually as you passed by students, making your way back to the Undercroft with a smile on your face. You smiled as you greeted Sharp as you walked by, who greeted you in return as he spoke to another professor. You smirked to yourself as you passed by Leander, who had changed into fresh robes as he talked to his friends, asking them if he still smelled weird. You turned a corner as you spotted the entrance to the Undercroft, looking around before you quickly disappeared. You tiptoed across the ground as you smirked to yourself, hearing Sebastian’s loud voice echo off the walls.
“I can’t look him in the eye ever again, do you understand? How can I walk into the class now after this?” Sebastian shouted, head in his hands, as he sat down. You watched Ominis as he smiled, his shoulders shaking with laughter as he listened to Sebastian. You walked closer, clearing your throat as you hid a smile. “Sebastian? Are you alright?” You asked, standing in front of him as he shook his head. “No! I am not alright!” He shouted, looking up at you with red cheeks. You bit your lip as you held back a laugh, forcing a frown as you looked over at Ominis, who only shook his head as he continued to shake. “Well, what happened then?” You asked, patting his head in hopes of trying to comfort him. He sighed as he pulled the boxers from his robe pocket. “This! Sharp had it for some reason! He handed them back to me, it was horrible! I don’t understand how he even got his hands on them!” You broke a bit as a small laugh left your lips, quickly bringing your hand up to cover your mouth. “It’s not funny! It’s horrible!” He shouted, his voice breaking slightly. You nodded, biting your lip harder. “Of course, you’re right. Was that all?” You asked, watching Ominis from the corner of your eye as he covered his mouth. “He- he said I was bad at acting!” You furrowed your brows as you looked at him. “I mean, he said we were dating, and that I was bad at hiding it!”
You couldn’t hold yourself together as your shoulders shook as you laughed. Sebastian watched you as you bent over, holding your sides as you laughed, confused. You felt tears in your eyes once again as your uncontrollable laughter got louder, unable to look at Sebastian. “It’s not funny! Why are you laughing?” You sucked in a few breaths as you looked at him, backing away a bit as you tried to speak. “I- I used Polyjuice to trick you. It’s rather hilarious! Your face!” You gasped, laughing harder as you confessed. “You what!?” Sebastian stood; brows furrowed as he made his way towards you. You quickly straightened up as your eyes widened, quickly running away as you continued to laugh to yourself. “Get back here!” You heard Sebastian shout, running after you as you left the Undercroft.
You shouted behind you as you ran, seeing Sebastian behind you. “I’m sorry! I swear!” You giggled as you ran around a corner, almost hitting the wall in front of you as you panted. Sebastian came up behind you in a second, grabbing you and pushing you against the wall as you continued to laugh. You tried to catch your breath as he stared you down, brows furrowed as he waited. “You got me, I’m a criminal.” You breathed, unable to stop yourself from chuckling again. Sebastian sighed as he placed his hands on either side of your head, staring into your eyes. You tried to hold in a laugh as you studied his face, his freckled cheeks still red; whether it was from embarrassment, anger, fatigue, or all three, you didn’t know. “Care you explain yourself?” He whispered, quirking a brow as you brought your hand to your mouth, hiding your smile. “I’m sorry?” You whispered, your shoulders shaking once again. Sebastian sighed as he waited for you to calm down. You looked into his eyes as you smiled softly, scrunching your nose as you spoke. “You’re adorable when you’re embarrassed.” His face heated up, causing you to smile more. “See? So cute.” “You’re not getting out of this by being cute.” Sebastian said, the corner of his mouth twitching as he tried to hold back a smile. “But I’m not the one being cute.”
“Where did you get my boxers?” Sebastian asked, frowning as you shrugged. “I asked Ominis to get them, thought it would be funny.” He scoffed as he shook his head. “You’re a nuisance. Pretending to be Sharp? You could have gotten detention.” You shrugged again, smirking. “But I didn’t. Ten points to me.” Sebastian smirked at you, taking a hand, and flicking you in the forehead. You quickly brought your hand up to where he got you, pouting. “Ow! Is that anyway to treat your non-girlfriend?” Sebastian bit the inside of his cheek, pondering. “Do you want me to kiss it better, then?” “Absolutely not. What am I, seven?” He sighed as he smiled, taking a glance into your eyes before he brought his face closer to yours. You felt his nose touch your own as he whispered. “I’m a great actor, for your information.” You scoffed, closing your eyes as you smiled. “You’re really not, Mr. Smitten.” “Says the non-girlfriend.” You huffed as you opened your eyes, crossing your arms. “I’m great at acting, fooled you. Though it’s not that hard to do.” “You just don’t shut up, do you?” “Make me then.” You couldn’t stop yourself from talking, eyes widening as you realized what you had said. Your cheeks heated up instantly as you realized just how close you were, watching Sebastian ponder for a minute before smirking. “All right.” With that, he closed the gap, his soft lips connecting with your own. You smiled into the kiss, tasting the apple tart that he had eaten during lunch, its sweet taste making the kiss even sweeter. You brought your hand up to his hair, massaging his scalp as you played with the soft brown locks.
You brought your other hand to tap on his cheek, signaling that you needed air. Sebastian reluctantly pulled away, breathing heavily as he tried to fill his lungs with air. You smiled as you rested your forehead against your own. “Is this what you do with your non-girlfriends?” “Cheeky.” You giggled as you placed another small kiss to his lips. “You love it.” “Of course, I do.”
