I thought the reason that that statement freaked him out is because Lucious was talking to harry as if he was possessed by Voldemort in an attempt to see if that was the case, and he interpreted the remark about age as a confirmation. It makes sense if you look at the statement as a deception because Ms. Longbottom walked up. I'm paraphrasing the first part:

I wont tell Ms. Longbottom to leave because "I prefer to deal with the part of House Malfoy that's my age" =>

I would like to tell Ms. Longbottom to leave because I prefer to deal with the part of House Malfoy that's my age(but I wont because I want to keep up appearances).

That reading seems far-fetched.

Let's go over the conversation....

Part I: Lucius accosts Harry and speaks to him as if he were Voldemort. Harry pretends to be Voldemort (without meaning to). Lucius maintains his calm.

Part II: Harry goes "you think I could benefit from doing Draco harm. But it is irrelevant, Lucius. He is my friend, and I do not betray my friends." Lucius goes 'what the fucking FUCK?'

Harry Potter and the Methods of Rationality discussion thread, part 9

(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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
