That is so so great :). One, it's lovely to read a story focusing on some of the older inhabitants of the Potterverse, and not having the wrinkles and soft bellies countered by some token pretty young thing. Two, Griphook and Muriel, gosh, the intensity there was quite impressive (and with the hotness, oh my). Three, Arthur, a complete mess without Molly, of course, but figuring it out bit by tiny bit, and ouch, grief suppressing his magic, that's a wonderful device.
