You have no idea how glad I am that you pointed out that section. It's one of my favorites. I sat with the description of the bathroom in Chamber of Secrets and imagined it in my head, and figured out how best to illustrate the fact it could be seen as beautiful, especially by someone like Luna.
I'm sorry I didn't do anything with Minerva, but when I saw this pairing suggestion, I fell in love. These two are two of my favorite characters. I never would have thought of it on my own. This fic was such a joy.
