This chapter significantly increased my probability estimate that Quirrell was entirely behind the plot to > 90%. Also, the humming torture was awesome, but not helping his case.
Also, who the hell was Bones' story referring to? That whole section heavily confused me.
I don't attach very high probability to this, but: Yermy Wibble? (The guy who proposed a magical draft and was killed for it.)
ETA: To clarify, the reason I think it's a bit improbable is that the mysterious guy's family was dead when he returned, whereas Yermy's family was killed at the same time he was.
Double edit: Forgot that Wibble was first introduced in Chapter 3, in a way that made it clear he's not this guy. This is clearly wrong, forget it.
The next discussion thread is here.
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 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
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.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
