Harry Potter and the Methods of Rationality discussion thread, March 2015, chapter 119

Gondolinian

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 119.

Plans for next chapter release:

Ch. 120 will post on March 12th, 2015 at 12PM Pacific Time (7PM UTC).

The next long chapter will be Ch. 122, posting on March 14th, 2015 at 9AM Pacific / 4PM UTC.

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.)

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

Huh? Harry thought it was McGonagall. What in this chapter changes that?

The narration in the passage is extremely suggestive that someone other than McGonagall was at work. Dumbledore and Quirrell used to be the main candidate hypotheses for who it was, until this chapter basically confirmed it was Dumbledore.

We do not know for sure. Here are the quotes: from chapter 6 [...] from chapter 8 [...] It doesn't look really like her style though.
