People seem to constant forget--Hagrid's status as a half-giant is secret. Everyone had a different theory as to why he's that big, but nobody thought it could be because he has giant blood, because then obviously he wouldn't be employed in civilized society.
I agree otherwise, however.
What Harry doesn't know that canon Harry figured out quickly is that Hagrid knows a lot about magical creatures. (He eventually became care for magical creatures teacher, after all.) He ventures into the forbidden forest, tends the nonmagical part of the Hogwarts gardens (which get attacked by magical creatures on occasion), etc. And if Harry did more digging into the Chamber of Secrets incident, he might learn about Aragog.
Knowing most of this, though, requires Harry to actually interact with Hagrid more than is strictly necessary, which doesn't seem to interest him.
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 97. The previous thread is at nearly 500 comments.
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, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25.
