"A.. a groan?" She asked tilting her head to the side again. The girl was completely useless, and it was apparent. The girl simply lay there, though she was happy that she had at least gasped, it wasn't enough for her. She needed to get something more out of this girl then a few tears and a gasp. It made her frustrations worse inside her and Zara kicked at her again, not really caring if it hit, but then started to pace. Pacing like a caged animal as she stared down at the girl tied before her. This wasn't working, she needed to see real pain. Fingering her wand, she thought for a moment. "Diffindo" She said, muttering the cutting curse. She knew there was a better one, but she didn't want to kill the girl. Hurting someone was fun, and even though she would have thoroughly enjoyed watching the light leave her eyes. For some reason Zara felt the need to meet this girl again, and maybe have a real duel, for Zara was slowly getting bored.
Shaking her head, she decided to go with it anyway, use a spell she had only ever heard of, and only once seen it in action, and seen how horribly painful it could be. Pointing her wand at the girl's back, she smiled and said softly. "Sectumsempra.." She watched a blind of light so bright she had to look away erupt from her wand like a whip. "Does that hurt luv? Does that make you want to talk? Blood is seeping out of your body, and you can't even say anything to stop it.." She smiled slightly. When she had cast Diffindo, the ropes had fallen off of the girl, leaving her on the ground, able to move, but probably in to much pain to do much else but lay there. Aiming a kick for the girl's head. "Well, sorry to hit and run.. but you have bored me, maybe we'll meet each other again." She said and leaned down, running her finger along the girl's cheek, she pulled it back to see blood on the tip.
Slowly, she put her finger into her mouth and smiled. "See ya around Ravvie." she said and spun on the spot, disappearing with a loud CRACK
