This one got a gentle smile and a shaking of my head. All the characters just seem to fit. Might have even make the ending of canon work.
fyi: There are men and women psychologists, or people who work with them, who do what Harry did (more or less) to help patients get past some bad personal experiences. After Luna connected Lavender to Harry, I wondered if that what you Harry was doing. Continuing with his "saving people" thing.
In any case, thank you for a very good story.
May the MUSE always be with you!!!
