It probably said something about Draco's personal growth that, upon seeing, from the corner of his eyes, someone seemingly cornered by a group of unfriendly gentlemen, his initial response was to change the direction of his lazy saunter over towards them. At the same time, he very casually slipped his wand into his hand, twirling it once.

The shield charm - modified, apparently - caught his eye, but he'd focus on that afterwards.

"Afternoon, gentlemen," he called as he approached, his voice a drawl. He didn't assume that they would leave whoever they were attacking alone at that point, but he did bank on getting the attention of at least one of them. Two, if they were stupid. And sure enough, two glanced over, one narrowly glaring at him, the other trying to figure out if Draco himself was stupid.

As soon as they looked over, Draco just smiled and stepped forward in an elegant lunge, casting a quick spell that sent the nearest man looking at him flying and toppling into the two next to him.
