What do we know of the second Hat-and-Cloak:

  • doesn't know Hermione well
  • clever, but not too clever (it takes him a LOT of time)

=> not Quirrell or Snape

  • has some motive, probably foreshadowed (EY is a good writer)
  • was recognized by Hermione

=> not anyone unknown

  • has no morals (mindrape)
  • knows that Severus Snape is a Death Eater
  • says he knows the true reason for the coldness in Harry Potter's eyes
  • and says he's frightened of it
  • and says he knows HP is dangerous to Hermione
  • says: "Lucius Malfoy has taken notice of you, Hermione..."

=> He's Yhpvhf Znysbl!

One thing contrary: He says he knows the true nature of Professor Quirrell's mysterious illness. This doesn't fit...

After listening to the podcast of chapter 35 I was sure that H&C was Quirrell. H&C told Zabini the slander about Dumbledor to tell Quirrell, and Quirrel knew that Zabini would slander Dumbledor when he talked to him. If Quirrell is not(or is not controlling) H&C then he would have had to find out the details of H&C's plot. Presumably there would have only been a single, surprised in the hallway, meeting between H&C and Zabini. The only options I see for Quirrell finding out about it is:

  1. Quirrell somehow knew the time and place that H&a

2prasannak8yAssume Quirrell is not able to model 'good' people well -> we know he is not all powerful, and this is certainly where he is weak - witness conv with Harry on 'give a finger of my wand hand', 'does it really matter what your friends think', etc. And each iteration with Hermione could have brought a different reason from Hermione, which was then subverted - we only saw one arc. Also H&C wanted Hermione as a willing participant, not as an NPC, much harder than simply memory charming her. It's very unlikely EY has used two different H&C, and there was the 'wards keyed in' statement of both H&C & Quirrell earlier. Will need much stronger evidence to say Quirrell is not H&C.

Harry Potter and the Methods of Rationality discussion thread, part 9

(The HPMOR discussion thread after this one is here.)

The previous thread is over the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread.  This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it. The latest chapter as of 09/09/2011 is Ch. 77.

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.  The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.

As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.

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.
