Maybe we should try to get the parchment back and destroy it before they find it.

I mean, they already suspect us. Is there some way they could determine from the parchment who did it, if they found it? Fred and George, could you summon it out for us? I can't go into Ravenclaw and I don't want to involve Sarah (besides, she might get cross with me, although I really do think she'd think it was worth it to get Padma).
