She laughed at his question.
Andrei was the one who provoked everything! Avis wanted only to reason with him, prove that every crim that he made deserved a punishment. He could not walk around without any guilt on his mind but she did not imagine herself to be the one who'd teach him a lesson. Teachers did that, parents did that, older sisters and brothers, but not Avis!
She was no saint in this case. She had her sins, but not as big as Andrei's. And now she felt only growing guilt: they were fighting in the school, area where such actions were forbidden.
Avis readied herself for an incoming attack, but much to her surprise, Andrei was hit with her stunning spell. She stood there, eyes wide and mouth slightly open. She knew how to defend herself, she knew how to fight and today she had proven to him that she was not the girl he could mess around with, but she did not expect him to get hit like this even when he was paralized with pain. Avis was one step from begging his forgiveness and yet she pressed her lips together. He looked so vulnerable now. No chance to fight back.
Although she had the advantage now, she could do anything she wanted with him, she felt that this was unfair.
Avis stepped closer to paralized Slytherin, looking at him in the eye. During this whole time she started hating this specific color. Blue. It was saddening that someone who looked as beautiful as Andrei had such personality. She could read the hate from his eyes. And maybe even a glimpse of pain from the former attack.
„I could just leave you here...“ she said, pointing with her wand at his chest. He was right, she would enjoy this if she wouldn't have any morality. She could use Sectumsempra on him, watch how he bleed until he'd lose consciousness and then heal him. Maybe even do something more wicked to his
„But I guess you got humiliated enough for today.“ She smiled to herself and stepped away from Andrei. She was still certain that he deserved to be punished, but not from her. Besides, he got hit by a girl, quite painfully and she even defeated him. For now. Still smiling, she released him from the hex and readied herself. After such defeat he'd sure as hell will be after revenge.
