For those of you confused by this comment: I believe Manfred assumes Lucius suspected that Hermione was replaced by a polyjuiced Bellatrix Black. Lucius implies that he believes Harry to be a de-powered Voldemort in their discussion at the train station, and also believes Harry to be behind the rescue of Bellatrix from Azkaban. If you rescued your powerful minion, you would want to keep her close about you for your own protection and to accomplish tasks beyond your magical abilities. Hermione Granger is known to associate with Harry Potter, so she would be the ideal candidate for someone to replace with Bellatrix.
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 97. 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.
