Oh, I think Sirius takes pride in what he does, that's not what I'm saying. And yes, from what little he's said, I think he and Regulus were very pressured to do well.

I think it's more that...either he personally never had to work hard to get top marks, or maybe it's because his parents pushed him so hard as a younger wizard that now he hates the thought of putting loads of work into anything. But mostly I think it's the former because he can be a bit of a perfectionist; he's just really unpredictable about when he'll get that way.

Do you think you'd still be fourth even if you didn't work so much over things? If you were... I don't know, sloppier or less obsessive about your essays?

I never said I was responsible for them. I said that I had in my possession an easy way to make sure they could leave the forest safely, no matter what, and that if I hadn't offered it, I would feel awful if something happened and they'd got hurt.
