Best rationalization I can think of, but I still don't approve of the change. Let us remember that Quirrell intends to help Harry become a Dark Wizard, in which case, since Harry is in the classroom, he should include Light Wizards in the class of people who can threaten the students present.
It also makes more sense to say "the adult wizard" since that sentence is the conclusion of a list of species that are dangerous, and "adult" sounds more biological.
Maybe there's an important reason for this change, but otherwise I think this is too much like a composer making inane changes to a piece after it's already written, or like George Lucas messing with the original Star Wars trilogy.
I think Quirrell is working with an unconventional definition of Dark. Something like "in violent opposition to you."
The next discussion thread 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 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
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.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
