This is outstanding. Just gorgeous and wonderful.

I can see it as canon that Harry is there when Hermione first gives birth, not Ron.

You wonder if someday you will die for this boy who lived. They will bury you in satin, you think, and your scars will bear a silent witness that you were, perhaps, in love with an impossible boy who (somehow) taught you so much more than books ever could.
