Rodolphus hated this place. He'd had work extra hard to put forth the proper foot of society. He'd honestly done his best not to provoke anyone but it seemed that every time he opened his mouth or used his quill someone wanted to take a jab at him. In fact, Rodolphus had done a rather fine job of keeping his wand in check. But if Potter was willing to allow him to take a few shots Rodoplhus was more than willing to oblige.
His wand had already been at the reading and as the stinging spell hit, Rodolphus gleefully accepted the blow of the spell. Sure, it would leave a physical mark or two but he'd put up with much worse at the hands of both his father and his lord so mentally the spell did nothing to him. Just as the spell hit he sent his own stinging spell back followed in quick succession by a roar of flames that would expand to hopefully catch Potter no matter which direction he dodged. "You'll have to do better than that," he laughed.
