Look. About Malfoy. He's really prickly, and sometimes he comes across like an arse. Just--I think there's something worthwhile there, really. He is trying. It's been a huge adjustment for him; he only recently joined our group, the Institute, and I think he's still reeling from the shock of revelations he got with that group.

I do think it was probably the right move to swear him in here, though, although I bet it would surprise the hell out him that I would say that. I don't think he thinks very much of me. He is utterly loyal to Harry Marvolo. So that's something.

Just...ignore his manner as much as possible and deal with him calmly. Mum, I bet you'll be able to do it really well.
