Kayla visibly flinched at the words thrown at her and she shrunk back even further, her wand almost slipping out of her hand. "I - I- you" she stammered pointing her finger at her grandmother. "The things you did were wrong. I - I had to turn you in. It was the right thing to do" Kayla finished off in a whisper. "You never loved me anyway, you made me do horrible things and you punished me severely when I didn't do as you asked." She had backed up so far that she was now pressed against one of the desks, with nowhere else to go. "And I'm not stupid" she added weakly.
