Hardest part to fake is Harry's sense of doom/scar pain/resonance: there probably has to actually be a Riddle in the Voldemort-body as it gets stunned, obliviated and transfigured. Better make sure it's a Horcrux V1 copy. So bring a V1 Horcrux, use it to overwrite the Voldemort body you create with the Stone, then possess that body on top of the Riddle already in there, then abandon ship right before the stunning hex.
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 116.
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.)
