"Don't. Unless you want a direct sterilization from me, future potential butt lord." "Wow, such venom. Correction, it's present." "Correction again, it's delusional."---Mattheo Riddle and Frolava(OC) "Alright brats, listen up. Today's class, we ain't doing funny spells to defend against dark arts." "Avada Keda ---" *GUN SHOT* "We finish it before it finishes us."---Professor Wolfgang Lockhowls(OC) and his DADA class "DETENTION--! You WILL write "I am worthless" 100 times with this qill, mister.......?" "Rodolfo. Professor Umbridge, are you sure you are qualified for teaching with dementia?" "OH...you INSOLENT PRAT!!" "If I am insolent, then you must be contumacious to even think that you can use the blood quill on a student. Come on, Umbridge, you can do better than using a blood quill or imprisoning." "Oh, what are you going to do about it, whine and cry for the headmaster to believe you?" "Worse. May Dumbledore forgive you, but I won't. Cruico."---Umbridge and Aiden Fenrir Rodolfo(OC) "History magic is fun students, trust me." "Do you know? Ha, I was there when I taught transfiguration to Voldemort. He was supposed to transform a rabbit into a jade cup. You know what he did? Little Riddle thought it was funny to make killing spells instead, and then I sent him straight to detention and gave him a D. Pathetic. he didn't even clean up the room afterwards."---Professor Xian Yi (OC) and his history of magic class "Oh, she's just a weak little Hufflepuff, what possibly can she----" "PURIFIX---!!!!" "........ Merlin's pants....did she just wipe out the entire army of Death Eaters with some kind of light pollution spell?" "What in the name of Salazar.....did she create this spell?" "Whatever that thing is, I think we're screwed up big for messing with her, mate."---Aurelia Mianovell(OC) and the Slytherin boys
