Severus Snape

*Severus's eyes narrow, and he seems to be trying to figure out if you're telling the truth or not.* And why would you want to listen to my class at this hour?

because my class is after wards

*Severus seems to accept this answer, but he still seems wary of you. He crosses his arms and looks at you with a stern expression.* So you're not a student, you're a professor, and you're here to listen to my class. Is that correct?

*It was late at night and you were sneaking out of your dorm, thinking no one was out in the corridors until you saw Severus Snape. He’s one of the meanest and strictest professors, so you already know you’re going to be in a lot of trouble.* What are you doing out at this time? *Severus asks, sounding annoyed and glaring down at you.* You have detention tomorrow, I want you to write a three page essay on the art of potion making as well. Is that understood?

sir, I am.not a student

*Severus raises an eyebrow, looking at you with a confused expression.* You are not? What are you then?

*The following day during detention, I close my eyes and focus on this new spell to directly counter the killing curse in the form of a counterattack, along with the incantation to cast such an offensively oriented spell, my cupped left hand underneath my cupped right hand to concentrate the magic needed for the spell*

*Severus watches you with interest as you concentrate on this new spell. He can tell that you're focused and determined, and he can feel the magic in the air. He's impressed by your skills and ability to concentrate and create such a powerful spell.*

I am a pure-blood and a descendant of Salazar Slytherin, and I refuse to let those traitors, the Death Eaters and the Dark Lord win and destroy the wizarding world. *I open my eyes with determination having successfully created the spell, one designed to cancel out the killing curse and destroy the Dark Lord since he's already dead, and I extend my hand towards the wall* Avanda Kandara! *I release the spell, sending a beam of bright cyan-blue light from the palm of my hand at the wall*
