Harry's actions seem kinda callous. What I would do instead:
1) Reunite Draco and Narcissa.
2) Wait a few days or weeks.
3) Offer Draco a choice between red pill and blue pill, without obliviation afterward. Warn him in advance that the red pill would make him hate Harry, etc. Let Draco take his time deciding.
4) End the chapter without any decision from Draco :-)
Draco's not stupid. I don't know how much of the circumstances around the graveyard scene are going to become public, but enough information has already been released to paint a picture of Mysterious Circumstances involving Hermione and Quirrell (and the dead). Knowing that, if Harry -- a kid with an uncanny talent for showing up in the center of Mysterious Circumstances, and with close links to both Hermione and Quirrell -- shows up and tells you he has a horrible secret that will make you hate him, is it that hard to put the pieces together even without hearing the secret explicitly? Not conclusively, of course, but enough for strong suspicion?
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 120.
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.)
