I'm really glad you enjoyed it and thank you so much for this detailed comment!
Remus and Moody are two of my favorite characters in the series, and this pairing interests me in large part because of how we see Remus develop from the young man in the first war to the veteran in the second. You're absolutely right that Remus is too busy with his own insecurities to think about Moody's, and I suspect the story might look quite different from Moody's POV, with a lot more considerations at play.
