A couple guesses about scenes that might be coming:
Harry has a (mostly) honest conversation with Moody about what happened to Voldemort, with an eye to adding more safeguards. They consult with the world's foremost expert on memory-charming powerful wizards into insignificance, Gilderoy Lockhart.
Hermione is determined to rescue Dumbledore from the Mirror, and a phoenix comes to her because of it.
I cannot for a second imagine Moody allowing Harry to hold on to Tom Riddle. There are too many ways in which keeping a superpowered, immortal amnesiac former villain on your person could go wrong. Harry must anticipate this, so can't consult Moody.
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.)
