Lucius is a slytherin, and not stupid. What if he really does believe Hermione is a pawn? The question remains — whose pawn?
Lucius might believe Hermione is Dumbledore's pawn.
Lucius already believes D killed his wife, and so he would have no trouble believing Dumbledore is targeting his son. In fact, it would be to Dumbledore's advantage (so might think Lucius) to target Draco in such a way that D can avoid taking the blame. If D wanted to impose political costs on Lucius, one way he might do it is to have someone utterly beyond suspicion be found to have attacked Draco. Then Lucius would have to use up political capital to punish an innocent little girl.
If Lucius thinks this way, it would explain his willingness to punish Hermione to the extreme — she's Dumbledore's pawn, and so he's going to take her away in order to impose costs on Dumbledore. For Dumbledore to speak up for Hermione would reinforce the belief that she belongs to D.
What do we make of Harry Potter's comments, and Lucius's reaction to them, in this light (given that Lucius thinks Harry is the dark lord)? His "unheard sentences" would likely be along the lines of "No shit, sherlock!", followed by, "why is the dark lord pretending to be stupid."
The funny thing is, Quirrell's testimony of someone with a motive to harm Draco is spot on: Dumbledore attacks Draco in order to impose costs on Lucius.
... are we really so sure Dumbledore didn't set the whole thing up?
EDIT: I think Quirrell set it up— but I also think there's a good chance that Quirrell didn't just set it up to make it look like Hermione attacked Draco, but rather set it up to make it look like Dumbledore set it up to make it look like Hermione attacked Draco.
If D wanted to impose political costs on Lucius, one way he might do it is to have someone utterly beyond suspicion be found to have attacked Draco. Then Lucius would have to use up political capital to punish an innocent little girl.
I see him gaining political capital by destroying the mudblood girl who publicly challenged and defeated his pureblood son. The purebloods in the WIzengamot were aching to abuse her.
EDIT: New discussion thread here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With two chapters recently the previous thread has very quickly reached 500 comments. The latest chapter as of 17th March 2012 is Ch. 79.
There is now 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.)
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, nine, ten.
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:
