Now Hermione learns Patronus 2.0 and destroys Azkaban. So both the Boy-Who-Lived and the Girl-Who-Revived can kill dementors. Sounds like "surviving/defeating Voldemort" is a plausible cover for explaining the origin of the ability to destroy dementors.
With Dementors out of the way, the cost of telling people the secret of the True Patronus becomes a lot lower.
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 122, which is the final chapter of the story.
Happy once-in-a-century Pi Day! (3/14/15 == 3.1415)
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.)
