Polyjuice would be an excellent thing. If Mrs L can spare some for us. I mean, I understand why we don't generally get any to use, but this is higher priority than most of what happens here.

Mind you, anyone taking our places would have a dreary evening if they spend it in Gryffindor, trying to tutor people and not give away they're not either of us. I reckon they could say we've got our own work that's got to be done, and then make everyone leave us alone for the night. But all in all, it'd be better if we sign up for the salle and whoever covers for us, does it there.

And you're right! Peeves could be brilliant if we can get him to do our business. We'd just need to have a fallback plan in case he decides he'd rather gives us trouble than help us.
