Lucius had noticed her but wasn't paying much attention to her. She looked upset and he was never good with upset women- usually made the situation worse truth be told. That was until she banged into him. "Watch it," he snapped automatically at her not really thinking how she would react. She wasn't a witch - or one that he knew anyway and therefore was even lower than the mudbloods- which luckily weren't here (as far as he knew anyway).
