This is fucking brilliant. Every last word is perfect-rather Minerva-esque in fact: crisp, clean, stern. I loved the ghost haunting Severus, the way Minerva is taking care of Moody, Minerva's opening lines when she brings Severus to her rooms (rather a "what happens here, stays here"). The ugly, rough relationship Severus has with Moody (and you touched me deeply with the reference to the Prewetts). Marvelous work. Off to rec. :)
