Thank you very much for reccing :-) I'm thrilled - thrilled! - that you liked it so much.
when Petunia has shown signs of character development, she's still faffing around trying to serve tea for everyone and cleaning manically
I've been thinking, actually, that none of these characters really changes all that much. Even in canon, they're pretty much set in their ways, and I was trying to convey that even though these people are fighting against a common enemy, what they are really fighting for is the preservation of their way of life. They don't seriously try to understand and get along with the others, they merely want everything back to normal. For example, when putting down my very first notes for this fic, I wasn't sure yet where I would be going with Petunia and Vernon. The basic concept was: Minerva and Aberforth - new love; Augusta and Frank Sen. - lost love; Petunia and Vernon - established relationship, and I was considering having Petunia leave Vernon, because she experiences character development and growth and he doesn't. But I abandoned that pretty quickly, because I didn't think that Petunia would leave everything behind. She likes her middle-class life and its order and she wants it all back.
Vernon, of course, never had the least chance to grow, the poor man.
See me ramble about my own fic... But I simply couldn't leave your lovely comments uncommented.
