Cosette could see the girl was frightened. She looked like she was ten years old at most. Probably a first year. Letting out a small chuckle, she retracted her wand hand from in front of the girl. She felt a tad bad. Whenever someone got on her nerves, she didn't result to violence. Well, that was her new rule. Her old one was to just annihilate the little sod until they wouldn't do it again. "Lumos Maxima." The light at the end of her wand flooded out a larger beam of light, making the whole floor easier to see.

Walking around the girl, she crossed her arms, a smirk on her face. "Maybe next time you won't be so clumsy, my dear Arabella." She chided, accent rolling with the words. Maybe a little fear was always best for the younger ones.
