Bellatrix flashed the girl a smile that looked nice enough, but was really quite feral. The girl was sweet, and young, and Bella would have fun with this girl.
"I'm sorry, I certainly didn't mean to. Better me than some animal, yes?" Which was probably what the girl thought she had been, and the thought made Bellatrix smile. The girl would be begging for an animal to have attacked her by the time Bella was done.
"What're you doing out here?" She walked around to stand in front of the girl, taking pleasure in being taller than her. If there was one way to be intimidating right off the bat, it was being taller than someone.
