Re: Sometime later...
It felt to Greg like Potter took an eternity to finally leave him alone. It was exhausting, being on your guard that completely for that long but Greg's relief was short lived. He'd been restacking the display of Skiving Snackboxes when he heard the door once more. It only took a glance to inform him this was almost certainly one of George's brothers. Greg didn't understand why George had hired him if it meant his friends and relatives were constantly going to have to pop by to make sure Greg wasn't... He didn't even know what they suspected he would do. If he'd wanted to hurt Weasley he could have done it without taking a job in his shop, wearing stupid pink robes and talking to customers all day.
Unlike some purebloods, he wasn't sufficiently up on the gossip to know which Weasley he was now facing. The oldest one had some kids already, he thought, so maybe it was him. "First day," he grunted, certain the man already knew that. "Can I help you, or are you here to see Mr Weasley?"
