Lavender hadn't done any investigation into demons before this. The demon thing was Octavius' idea. Why didn't he tell her all of this? How the hell did she give him a soul? Who's soul? She wasn't in any position to take souls. She didn't want to. "Ah... well. We may have a problem there," she leaned back further away from him nervously. "I don't have any souls to give. I wasn't aware of this payment. Is there something else you might... like?" She asked hesitantly.
