I've been meaning to come and comment on this ever since I saw your post yesterday, but life gets in the way - you know how it is. In any case, I've had to read this over a few times to get my thoughts in order, because your storytelling is so wonderfully subtle. I really love the picture you've painted here - of a relationship that's sort of unstable and delicately balanced (and threatening to collapse, of course). I love the way Tonks is both defensive and defiant when she talks about their relationship - the flat and their sex life in particular. And the little touches - Remus saying "and don’t interrupt me, Dora" speaks volumes about both of them and the dynamic between them.

Overall, then - brilliant, and as always I am in awe of your ability to tell a story so well. :)
