How much of the cost of saving Hermione was announcing that Harry responds to blackmail? He made his entrance onto the stage of players in a way that cannot endear him to any of the others. No matter what he did, he would antagonize Lucius, but he demonstrated an extreme disrespect for the rules of the game and preserving the existing order is in the interests of all the players. Not to mention, he implicitly declared challenge to the ministry of magic. If he actually had the power that Lucius believes he does, he might get away with that, but he cannot survive for long against the Aurors. As it stands all that is keeping him safe is Dumbledore, shock and bluff.
I rather expect the first of those to disappear sometime in the story. I have no idea how General Chaos can develop an ultimate weapon powerful enough to stand off the nation of Britain.
On the other side of the coin, Hermione is extremely valuable. She's almost the 1st or 2nd best duelist in 1st year and her aid probably doubles Harry's ability to do research on magic. Unfortunately for Harry, while those skills would be decisive if he could go hide and research for a few years, I doubt that he'll get the time.
Well, if his trick for deactivating other wizards' patronuses (patronii?) works, he basically has an unblockable army of instant-death assassins, the only defense against which would be Apparition... That's a pretty good ultimate weapon in a Mutually Assured Destruction sense. And as long as we're discussing mutually assured destruction, there seems little doubt that Harry would be able to transfigure nuclear weaponry. Or botulinum toxin (of which it would take an appallingly small amount to kill every human on Earth). Etc, etc. Harry does not lack for access to Ultimate Weapons.
The new discussion thread (part 15) 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 82. The previous thread passed 1000 comments as of the time of this writing, and so has long passed 500. Comment in the 13th thread until you read chapter 82.
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.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
