I have my suspicions that Edward may be the man talking with Abby over the pit Bella is in, or at least survived. I don't really know why. The sheer number of times he was mentioned as "the man" made it feel to me like you really didn't want him identified. Bella didn't find a ring in the ashes, and Abby and "the man" never referred to any gender, so it could have been Irina attempting to go berserk on the wolves or Bella. The only males present were Aro, Demetri, Afton and Edward, and Bella has heard them all except Afton. It's possible Edward was subdued by Alec and extremely tweaked by Chelsea and Abby to the point where Bella doesn't recognize his voice though.
I'm certainly no Edward lover (yours was good though), so I'm fine either way. Bella won't have a happy ending even if she achieves all her previous goals if he's dead though, so that would be sad. For a moment there I thought both Bella and Edward would die, leaving the sequel to Elspeth.
Bella's never heard Demetri speak; what are you talking about? And Chelsea and Addy don't change anyone's voice. The guy Addy's talking to is Demetri. That's not a big deal, it's just not something Bella could have figured out.
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website <strike>(warning: white text on black background)</strike>.
Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
Spoilers for the fanfic itself as well as the original novels need and should not be hidden, but spoiler protection still applies for any other works of fiction, except for Harry Potter and the Methods of Rationality chapters more than a week old so we can freely discuss similarities and differences.
EDIT: Post-ginormous-spoiler discussion should go to the second thread. (If you have any doubt on whether you have reached the spoiler in question you have not.)
