Nick lowered his shirt calmly and gazed at her for a while. He hadn't lied in the sense that she thought but he had deceived her, and this was unfair. Nick was not a practical Slytherin though, he was a fun loving guy who respected those who deserved respect. Your typical Slytherin was a fowl, stuck up Death Eater supporter. Nick sighed, Rose was to young to understand all this, she probably thought he was a monster for using Dark Magic. Nick spoke calmly, his voice failing to portray any sort of emotion "Rosalie, you have spent the past half hour with me, you know Im not a practical Slytherin and you know Im no dark wizard. You shouldn't look at Dark Magic as an evil thing, more as a thing which should not be used lightly. If I remember correctly Dumbledore and Harry Potter, our world's greatest wizards were skilled in Dark Magic, yet they were protectors of all that was good. The ministries aurors were given permission to use unforgivable curses on Death Eater's during the first war. Dark Magic isnt evil, its what we use to fight and protect ourselves. Too not be as skilled as you can in them is foolish. But what you think of me is not important, what is important is that you listen."
Nick sat himself opposite her and gazed into her eyes. He could tell she was disgusted at him but there were more important things to say "Alot of student's died up at the castle over the summer and if you aren't carefull you could be victimised. Your sibling's are older and can defend themselves, people that wish your familly harm are going to come after you. Make sure you stay on your guard, and if people are bothering you, you come and find me ok?"
Nick stood back up again, no doubt Rose would want a bit of time to think, and he really should get to patrolling the coridors. "I have to go now, to patrol the coridors, but Il always be around for a chat. It was really good meeting you, your a real credit to your famillies name, even if they dont know it." He flashed her that charming smile of his then gathered up his bag. Nick pulled out the compartment door, then turned to face her "Its not the magic that we use that makes us good or evil. Its whats in our hearts." He shut the compartment door then walked of down the corridor.
