While I didn't realize Quirrel might be lying about his willingness to cooperate, the Memory books aren't in the restricted section and we haven't heard anything about him sabotaging Harry's attempts at taking over the universe since chapter 95 (except for some sort of deception in 100/101... "what a fiasco" is not something you would hear Quirrel say to himself audibly and honestly). Maybe he was in Zombie mode until 99? We wouldn't know, since we weren't in Harry's POV since 2 days after that chapter, although in his shoes I would have attempted contacting Quirrel as soon as possible.
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 99, 100, and 101. The previous thread is at nearly 500 comments.
There is now 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.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.
Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27
