Yeah, but who would think that George and Fred are trying to kill the Lord Protector's son over Quidditch? And no one knows of any other reason for them to be hacked off at him enough to do something mad like that. It doesn't make any sense, Ron.

Except that someone's obviously got it in for him. Who could it be? And how could they get at the bludgers? I mean, they're kept in Madam Hooch's office, right? Or could someone have hexed the bludger long-distance?
