Also, I like the way you hint at -- but never answer -- the question of what Minerva's needs are. We see what Remus and Severus might need from her, and I'm now enjoying speculating about what it is she might get from them.
You're absolutely right, and I'm pleased that you mentioned it, because I did want to suggest that question between the lines. A sequel would be a very sensible addition, in theory, of course. :)
