Gorgeous! And funny as heck. I loved recluse Harry getting really, really creeped out by that portrait, reluctant!Remus and Ron so much. Though I hope you'll forgive me for pointing out that Narcissa stole and ran away with the entire piece :). I adored her bickering with Remus at the beginning to no end, as well as her appearance at the end - with the glaring lack of Ron/Narcissa out there, every Ron-Narcissa moment warms my heart, and this was so much fun :).
I also enjoyed Harry getting the upper hand with Snape in old insolent tradition and Snape's enthusiastic response despite the verbal snarkiness. Fun fic, mystery person! ;)
