The Officials involved have believed Quirrel to be David Monroe for a long time (chapter 84), that seems to have become the Official Story over the last couple days, and Mad-Eye Moody knew that Quirrelmort should have been fired out of a cannon into a sun as soon as he took the Defense position, so they've been asking questions and taking the first reasonable answer for a while.
I'm fully expected Moody to dive through a door with stunners flying, yelling "Not paranoid enough!" because /someone/ didn't expect door transfiguration, but most of the other people involved have already gotten suspicious and had their suspicions allayed.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 118.
Plans for next chapter release:
There is a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
