Blaise's attention was pulled from the pair he'd been watching to the new arrivals. He noted the way the lady cared for the boy and couldn't help but smile when he waved her off as he launched himself into the air. It was the same sort of response he would have given his own mother had she fussed over him in any manner. Not that the lady was necessarily too overly involved in the boy's reaction.
"He's a fine flyer," Blaise said after they'd sat there for a moment. The boy was doing quite well. "He'll make a house team easily when he finds his way to Hogwarts."
