Very interesting! I went back and reread the epilog before this last chapter came out, and so I see where you came from with this. I'm slightly confused, though, about Hermione's children; I'm thinking that Rose is Harry's by blood, while Hugo is Ron's?
I'm looking forward to seeing what you write next!
Author's response
Yes, Rose is really Harry's child, although few people would know it (Harry, Hermione, Luna, and perhaps Ginny)and only a few would suspect it (Molly, Ron, and Ginny, if she didn't know for certain). Hugo is Ron's, and has inherited their worst characteristics, lazy (Ron) and domineering (Hermione), even if Harry hopes that this will turn to pranking instead of bullying.
