Despite Wade's attempt at looking threatening, Rozalia wasn't cowed in the slightest. She'd grown up around truly frightening and intimidating people; scarred and grim Aurors always stopped at the house following her Mother's death, to check up on the family; and her Father's Army friends were always visiting throughout the months. She'd grown used to being around trained and paid killers of both the Muggle and Wizarding world, so she wasn't the least bit frightened by a little boy who thought he was being scary.
Standing up and facing Wade - well, she was around his mid-chest, so she wasn't really facing him, but whatever - her face appeared calm, but her eyes and hair told another story. Although not pissed off enough to go full fiery red, she-devil pigmentation, her anger was tickled enough to produce a warm, chestnut-y colour to emerge from the roots of her hair, easing their way down till the previously happy blonde colour was swallowed up at the tips of her curls. Roza's eyes were still her neutral brown, but within them, there was a look not to dissimilar from the infamous 1000-mile-stare. It gave off enough metaphorical fire to prove that she wasn't going to be a victim. Ever.
"Listen up, buddy." She began, getting close enough to him to show she wasn't frightened by him. "I understand the whole ''new kid thing'' you've got going here - it's the same at any other school. First years are nobodies, right? But we're not going to be first-years forever, assbutt. And I'm already pissed off at you. So how about you 'scram', before I let my imagination run wild on ways to hurt you." Roza's voice was low and measured, the hint of a smirk on her face. "And trust me, I can hurt you. And I don't need a wand to do it, either. I can make you squeal like the little pig you look like and barely break a sweat to do it. So, if you want to stick around and continue messing with me and my friends here, don't say I didn't warn you. However, the safer option would be for you to round up your buddies, and get the hell out of Dodge." She stopped, finally, still retaining eye contact with Wade, who had broken out into a nervous sweat. He probably hadn't ever been spoken to like that in his entire life, let alone by a little girl first-year.
