Oh, dude. Snarky, perhaps passive-aggressive house-elves and glimpses of a moste intriguing relationship between Dumbledore and Flitwick? Um. YES. Particularly a fan of the insight afforded into the lives and ways of house-elves, the bits of gossip flitting throughout (talking about the robes, for instance... and oh-god, the thoughts on Lockheart *snerk*). Nicely established dynamics among the elves, by the by, sketching more-than-adequate images of even those seen only for a few moments.
Bugger. Typically, I want to kick house-elves and make them stfu. Now I wish to hear more of and from them. I curse and I thank ye for this, aheh... Verrah nicely done.
