Maybe that's a red herring, and the true explanation was given in the previous chapter:

The Dark Lord is Harry. The power he does not know and which will destroy him at the end is:

"Indifference," Harry whispered aloud, the secret of a spell he would never be able to cast

Unlike Quirrell, Harry considers the rest of humans to be his equals. At some moment he will need their help to change the laws of physics, but they will all ignore him. Later Harry will grow old and die. Or someone will kill him for some trivial reason. There will be no one else like him in this universe, so finally the entropy will tear the stars apart.

(Just kidding.)

Unlike Quirrell, Harry considers the rest of humans to be his equals.

Except Ron, whom he considers unworthy of existence.

Harry Potter and the Methods of Rationality discussion thread, January 2015, chapter 103

New chapter, and the end is now in sight!

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 103.

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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
