Draco just grunted a bit at his retort. If he wanted to go fly, then he should go fly. Better yet, fly out of bounds and let Draco bust him for it and give him detention. That'd probably please Carrow and maybe word would get back that he'd done something right. That was a pleasant thought.
He was about to encourage him to go fly off, when Potter went on to make a jab at his appearance and went even further to insult his economic situation. It made Draco think of his parents and how they were suffering at home, and was not the right card to play with him. Or in Harry's case, it was probably the one he was going for. Draco sat up abruptly and shot him a nasty glare. "Yes, well, not all of us can pull off that look as naturally as the filthy bunch of Weasley's you run around with."
