To answer your direct question, I thought you did a terrific job of capturing Narcissa's voice. I wasn't 100% on all of the particulars, but this sounded like her, even if one or two thoughts seemed a little out of place. I'll explain below.
The idea of Narcissa cleaning out the unused rooms in the manor in preparation for Draco's wedding was a really clever way to both advance the timeline and put her where she needs to be -- physically and emotionally -- for this scene. Her ideas about the value of old, well-cared for things seemed very consistent with her personality, as well.
The one thing that rang a little odd to me was that she would still be so committed to the idea of blood purity. She's come to the realization that the ideal is nothing that's worth fighting a war over and I think that's perfectly in harmony with where her character was at the end of the war. But statements about the dilution of good wizarding blood sounded a little too Voldemort-ish to me. Maybe she's just come a lot farther in my headcanon than she has in yours.
I loved the fact that she was throwing away everything that reminded her of Bellatrix. That was real progress. Rejecting her elder sister and everything that goes along with her seems like a very important step to relinquishing her past and moving on.
Lucius - I was rather fascinated with what you did with his character in this chapter. He really has changed a lot. He seemed unconditionally supportive of her and I actually felt a genuine willingness to reconsider his thoughts on Andromeda. It surprised me, but I liked it. Maybe he'll finally have a heart to match his amazing, beautiful, flowing hair? ;)
Again, small steps. I really like the fact that you're taking both of your leading ladies up the long, steep, rocky path to reconciliation. Nothing is too easy; nothing happens too fast. You're capturing the small moments that eventually lead to a big change, and I think it's a brilliant approach. Well done!
Author's Response: Hmm. I think that you're right that she came a lot further in your headcanon than mine, but in your headcanon, isn't she a good deal older? I think that she does let those ideas go little by little, especially once her grandson gets involved with halfblood Rose Weasley, but at this point, I see her as still reintegrating into the general Wizarding world - if I was a halfblood or a Muggleborn, I know I'd be wary of trusting any of the Malfoys, especially the two older ones! She does get there eventually - in fact, I'm about to start writing a scene in which she meets Rose about 20 years down the line from the point, and she's a lot more accepting. I just think that for someone like Narcissa, it was probably a long, slow road.
I'm glad you liked the fact that she was getting rid of everything that reminded her of Bellatrix; I agree that that represents progress and the beginning of her really being able to move on from her childhood and the ideals she was raised with.
I'm glad you found my portrayal of Lucius interesting! I do think that his being somewhat open to reconsidering his opinion on Andromeda represents a pretty drastic change (though I also think that part of it is that he's saying what he thinks she wants to hear). I do think that he was probably a bit more sympathetic to his family when they were alone than we ever saw in the books, because Harry was seeing everything through a very different lens. I always had the impression that Lucius cared deeply for his family. However, I also think that he *did* rediscover his heart a little when he had to watch his wife and his son be terrorised in their own home, and was probably more prone to sympathy and being softer in general after that.
Thank you so much for the review, and I'm sorry that it's taken me awhile to answer it - I've had RL stuff going on, but do know that I really, really appreciate it.
