I think things could end up worse than that. Harry's solution, whatever it may be, could well tip off Lucius that he is not in fact Voldemort. And once he's got Hermione out, Lord Malfoy would go after this first-year hard, before he can grow up. A few threats to a few parents and Harry and Hermione will find themselves seized by five seventh-years and portkeyed to Malfoy Manor.
But Harry is in fact Voldemort - in a certain unconscious sense.
Lucius decided that he is Harrymort because of Harry's reply to Quirrel's Christmas speech, but he would never have thought about it if the preexisting Harry Potter - Voldemort connection had not brought the hypothesis to mind. And that connection, the hints that make up the real majority of the evidence for the Harrymort hypothesis, is made of true evidence.
If Lucius now came to disbelieve in Harrymort, he would not be discarding a completely false hypothesis.
The new thread, discussion 13, is here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With three chapters recently the previous thread has very quickly reached 1000 comments. The latest chapter as of 25th March 2012 is Ch 80.
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: one, two, three, four, five, six, seven, eight, nine, ten, eleven.
As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.
