The obvious question is, why did Quirrell cause Harry to believe that Quirrell is Voldemort? As a background assumption, Quirrell plays the game one level higher than Harry. Quirrell is able to model people very accurately, and has recently been uncharacteristically sloppy. Quirrell is also obviously prepared for Harry to figure this out (gun, smile, etc.), and I would think it likely that he could craft a plan so that he would successfully avoid suspicion, so I'm expecting that Harry believing that Quirrell is Voldemort is part of the plan.
What's his game?
The only thing that comes to me instantly is that Harry is now more likely to just accept whatever Quirrell villainously monologues next as true. I'll note that people are already accepting this as some sort of confirmation that Harry is Tom Riddle. CONSTANT VIGILANCE, PEOPLE! All we have seen is Quirrell say "Hello, Tom Riddle," to Harry!
It's odd, because Quirrell went so far out of his way to appear to be dying. He set himself up to be caught drinking unicorn's blood. So it's very strange for him to give that away.
New chapter!
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 104.
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.)
