Well, I didn't exactly see. I was looking away when it happened. I was talking to Lavender, but Katrina said that just as Draco Malfoy stepped up to bow to the hippogriff, there was something, some kind of scuffle between Vincent Crabbe and Millicent Blustrode--I dunno. Something one of them did upset the hippogriff. And it reared back and started, you know, slashing. Those claws are really sharp.
