Personally I'm assuming that Quirrelmort rescued Bellatrix to influence Harry. He now has first-hand evidence that Harry was engaged in a major crime, has shown Harry a part of the Wizarding world which he could never accept which was enabled by democracy, has shown Harry that Dumbledore isn't as proactive as Harry would want him to be, almost convinced Harry that a revolution is necessary, convinced Harry to lie to protect him, and has made Harry feel sorry for Bellatrix. Generating a 'false alarm' of Voldemort's return is a nice side effect as well if he doesn't plan on acting immediately, Dumbledore may well have just expended significant political capital too early. If he was planning on going through with the ritual, then he had Harry right there with him. (Although he could have just taken some blood while Harry was asleep, of course.)

The only motivation I can see for him to retrieve her otherwise is that he couldn't remember what happened at Godric's Hollow or to the Longbottoms, so he wanted to retrieve Bellatrix to find out, he regretted what he did to her (seems unlikely), or he's not Quirrelmort, and is really just a powerful but neutral wizard who wants to try and retrieve some of Slytherin's magics.

The most obvious motivation given what we know about Quirrelmort and what he needs to regain his old power is that he retrieved her for use in the spell that will restore his body. For his motive to be anything else would constitute a twist.

(The HPMOR discussion thread after this one is here.)

The previous thread is over the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread.  This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it. The latest chapter as of 09/09/2011 is Ch. 77.


The first 5 discussion threads are on the main page under the harry_potter tag.  Threads 6 and on (including this one) are in the discussion section using its separate tag system.  Also: one, two, three, four, five, six, seven, eight.  The fanfiction.net author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.

As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.

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:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it's fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that "Eliezer said X is true" unless you use rot13.
