Magic so I could have one. She had to tell them that I was a model student, and that I'd never, ever use it for anything except my studies.... I've been turning it back so I could do hours over again, that's how I've been doing several lessons at once, see? But...

"So your telling me you mess up all of space and time for homework?" breathed Amelia. Harry could swear he could see steam coming out of her ears. Hermione waved her off.

"Harry, I don't understand what Dumbledore wants us to do. Why did he tell us to go back three hours? How's that going to help Sirius?"
