Thank you so much for your kind words! I'm so glad you liked it. I've always felt sorry for Marietta so was really happy to be able to explore that part of the story from her point of view. As much as I do like Hermione as a character, she made mistakes, and her treatment of Marietta (particularly in terms of it being permanent) really does irk me. I never thought that Marietta's betrayal was done out of malice, but out of genuine fear, so I was glad to give her a voice here.
Once I finally decided on a pairing, it was amazing how right these two felt together. :)
