Eh. I think Snape already understood that Dumbledore was manipulating him. From the interlude with the confessor:
“It's strange," Snape said quietly. "I have had two mentors, over the course of my days. Both were extraordinarily perceptive, and neither one ever told me the things I wasn't seeing. It's clear enough why the first said nothing, but the second..." Snape's face tightened. "I suppose I would have to be naive, to ask why he stayed silent."
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 121.
Plans for next chapter release:
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.)
