I'd still rather duck and take whatever he dishes out than do that to Carrow. I mean, you've never seen my Gran, and what she'd do to me if she ever knew I'd used that curse--well, that would be almost as scary as anything Carrow could do. And Gran's family, so she'd hold it over my head forever, unlike Professor Carrow, who I hope I'll never see again after I leave Hogwarts.

About Percy---I dunno, Ron, what do you think?
