I've also been thinking along these lines, anyone remember this part from the opening ceremony?
The young, thin, nervous man who Harry had first met in the Leaky Cauldron slowly made his way up to the podium, glancing fearfully around in all directions. Harry caught a glimpse of the back of his head, and it looked like Professor Quirrell might already be going bald, despite his seeming youth.
"Wonder what's wrong with him," whispered the older-looking student sitting next to Harry. Similar hushed comments were being exchanged elsewhere along the table.
Professor Quirrell made his way up to the podium and stood there, blinking. "Ah..." he said. "Ah..." Then his courage seemed to fail him utterly, and he stood there in silence, occasionally twitching.
"Oh, great," whispered the older student, "looks like another long year in Defence class -"
"Salutations, my young apprentices," Professor Quirrell said in a dry, confident tone.
It seems to imply that becoming the second victim of a Horcrux might not necessarily create a mishmash of personalities, but instead have them competing as separate (maybe "partially mixed"?) identities. This would also explain why Harry consider his "dark side" different from himself.
Yes, that often came up in past discussions. The problem is that the dual persona part seemed to get dropped early on and it changed to one of energy - Quirrel going into zombie-mode, not shy-Quirinius-mode. Presumably when he was up there on the podium, he was trying to summon up the energy for his speech.
New chapter!
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 102.
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.)
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
