Sebastian Sallow x Reader
WARNING: angst, slight violence
NOTE: Anon request for "ok a request.... Someone dosing you with love potion and Sebastian being extremely jealous and then finding out what happened and in an act of rage uses crucio on them"
"Sebastian!" You nearly collapsed when you ran into him, "You have to help me find Percy." The longing in your voice had him baffled. You both always had take turns being his partner in potions and whoever was stuck with him had basically drawn the short stick.
Sebastian stabilized you, visible disgust on his face, "Uhh, why? We had our daily dose of disaster to periods ago."
You hid your face in your hands, unable to hide the blush on your cheeks as you peeked out at Sebatian.
"Don't you know? I love him. He's so dreamy and I - I can't be without him for this much longer today! I have to find him."
He caught you by the arm as you tried to dash past him, "Y/N? What are you talking about?" You just giggled and pulled away, "Sebastian, you have to stay off of me or he'll get the wrong idea!" With that crushing statement you ran away leaving him stunned.
He was infuriated. Amortentia wasn't something to fool with in the first place, but somebody he knew you were downright not interested in using it like this? And now you were pushing him away because of it?
Sebastian rushed to find Professor Sharp and let him know what was going on, trusting him to be able to track the you down first to set things straight before you did something stupid.
As he ran around the castle searching for Percy himself his anger just continued to boil into rage. Now the bastard must have just been hiding out somewhere, knowing he had been found out and would certainly be in a lot of trouble.
Percy was spineless, but not that bright so Sebastian finally had the realization that maybe he would try to run away - and he definitely wouldn't do good at it.
Sebastian stormed outside and finally found the coward just outside the castle grounds. He was just beyond a gate, fumbling with some sort of map. It was dark at this point and the idiot wasn't even using lumos to be able to see.
Sebastian ripped him up from the ground, slamming him into the stone barrier he hid behind, wand at the boys throat.
"How stupid are you? Using some dumb potion like that on the person who's supposed to be mine. Who always has been mine even if she hasn't figure it out yet."
The boy struggled underneath Sebastian's strong grip and stuttered, "I-I-I don't know, I just, just thought they already liked me from how they were as my partner in class. I-"
Sebastian tightened his grip on Percy's color, pinching the skin that was below it.
"Nobody wants to be your partner!" Sebastian spat at him, eyes wild as he thought about what could have happened to you if he hadn't run into you first. Who knows how Percy could have taken advantage of you, he could have held your hand, kissed you, he could have tried taking your clothes off and you would have let him only to come out of it all completely devastated.
Sebastian dropped the pitiful boy back onto the ground with a thud, seeing him shake in fear. His thoughts were clouded and he had been toeing the line with learning the dark arts, but keeping them locked up. He felt like know was the time to use them, to show a scoundrel like Percy what wasn't okay.
"Cruicio!" The words left his mouth and he felt the sheer power of all the rage going through his wand to the brightly color sparks shooting out the tip into Percy's body.
Percy convulsed and cried out in agony from the ground. Sebastian grit his teeth together for focus before his wand was suddenly knocked from his hand and he, too, was in the wet grass.
"I - how dare you - you -" "Sebastian!" Your hand connected with his face to bring him down from the high of the power he just wielded.
"He's not worth it! We - we have to fix this!" You had tears in your eyes as you offered him a hand to get up. You watched the fire from his eyes burn out as he looked at you and then over to Percy where he layed curled up and panting.
Sebastian kept opening his mouth to speak, to give some good reason why he did would he did, all he could squeak out was, "I didn't want to lose you."
You sighed. You were exhausted from the ordeal with the position, then from helplessly searching for Sebastian, knowing something like this would happen. You just didn't think it would be this bad.
"Turn around Sebastian." Your voice was hard and he listen to you without question, but he was still terrified about what was to come.
You focused with every fiber of your being before drawing your wand at Percy, "Obliviate." You used a few spells to patch up some of his pain before reminding him he was in a lot of trouble for that love potion. You let him know to be much more careful next time he was going to try and run off of the unprotected school grounds as well.
You sank to your knees and dropped your head into your hands. You couldn't just let them take Sebastian away. He was an idiot, true, but he was you're idiot and that meant you had to protect him no matter what, just like he did for you.
Casting a charm to remove the memories of the events was probably for the best anyways, you knew how hard it was for Ominis to live with the aftereffects. It still just felt wrong. It felt like you had just casted an unforgiveable yourself.
Sebastian knelt down beside you, wrapping his arms around you and you just crumbled into more tears.
"I want forget what you did Y/N. And I...I'm sorry. I just couldn't let anything bad happen to you." You held onto him as he spoke. You understood, but it didn't make it any easier for him to be the person you cared about so much.
"I know I can't take this away from you. Merlin, I wish I wasn't such a fool, but I love you Y/N. I swear I can show you in better ways. I swear." The last part was barely a whisper from him as he seemed like he was trying to convince himself he was capable of any better.
