Making Percy's plan, for me, was the best part of writing this. And I did have fun playing with the other characters too, ones that don't usually find their way into my stories, for some reason.
Writing Harry and Snape's friendship felt odd; I had to keep reminding myself that this wasn't going to end up a Snarry.
So pleased you enjoyed it; thanks for the investment of your time to read it, and for your thoughtful comments.
