As the stranger approached Bill's hand dropped down by his side, wand between his fingers. It was better safe these days after all. "New?" Bill wasn't sure exactly what that meant, but the other man appeared unthreatening as of yet so he didn't raise his wand up, preferring to wait.
People who introduced themselves didn't tend to be too dangerous and Bill waited until he was closer and the fire lit up his face before he waved in return. "Something like that," Bill said. "Where's here?" Yes that was a good place to start.
Bill was good at keeping calm under pressure, but he didn't like being on the backfoot like this. "I'm Bill," he added after a beat.
