It was quite interesting that the boy had called out to him. Roth stopped and turned, waiting for him to catch up. He reshouldered his backpack and regarded the younger man. "No. Have you?" he asked. He hoped vaguely that they wouldn't be troubled by the refugee just at that moment. In order to maintain his story of being an actual Hogwarts employee, he might have to attempt to capture him. He wasn't entirely sure of his chances with someone actually on guard for such things. Most of Roth's victims wandered in innocently and never saw it coming.
