You have shown Luna and Hermione as growing closer as friends that are able to suport and care for each other. Is there any chance that if Harry reaches a point that he says the he cares for both that they can except sharing?
I went back check what was going with Tonks and wonder if there would be a chance that they could become "kissing" cousins?
I think that a diamond formation is much more defensible than a duo or triangle ones. Armies from Rome through the U.S. cavalry to modern day usually have a point men, outriders, and a those who watch what is happening behind the group. And people that work together continually over time and know how each in the group is going to react are considered the best.
I was glad to see the Ginny had decided that Nevil would be a very good replacement for Harry.
Thank you for a very interesting story. I look forward to seeing where you go with this.
May the MUSE always be with you!!!
