Just a comment on Scorpius calling Harry gorgeous. I really wanted to show that Harry's image of himself, and how other people saw him were not the same. He felt tired and empty, but that didn't leave him unattractive to Scorpius. I wanted to show their attraction to be very mutual, considering their ages.
That is what I thought you were trying to do. Also, I think your Scorpius is pretty intuitive, and he could see that Harry felt empty and old, and knew that he himself (Scorpius) had had a hand in making Harry feel that way. So it was only right for Scorpius to reassure Harry that he still found him attractive and wanted him as much as he ever had.
