Thank you :) I was quite pleased when my muse insisted on dragging Narcissa into the story and giving it a little canon colouring. (I'll admit that I had no idea that that was going to happen at the beginning of writing. I do find this a lot with my writing - I start writing something, hoping for the best, and it wanders off on its own - sometimes in disastrously awful fashion admittedly, but I think this time it worked.)
