Another great last line. Although you might consider taking off the "he explained quietly" that part is implied and Harry's words might seem stronger on their own.

The Snape/Moody stuff at the begining was very funny. And your descriptions (as usual) were very amusing. I especially liked the description of Snape chewing his food and later Moody gimping out of the Great Hall. I also liked Snape when Dumbledore showed up. His reactions fit what one would expect if Dumbledore were in fact his dad. He made great pains to apologize for his behavior first... lol. Oh and I never expected Snape to refer to Lupin as "our dear Mr. Lupin"... but wow, you made it fit. If there were a contest, to see who could get the most ooc phrases to seem natural... you'd win.
