This needs to be said before you carry on as it’s a good story but I don’ get why you just didn’t let the parents die and Dumbledore takes The so called boy who lived to live at Dursley’s and his brother the mc lived with the grandparents. Also another point why isnt his brother called Harry and the Mc called let’s say hadrian or Adrian aor even Arthur cause it makes it seem he’s Harry from the original movie if you get what I mean.
The story is an AU fic (alternate universe), which is why it has all the added elements it will feature in the future. Hadrian is just an alternate version of Harry, which is why there are so many differences and similarities between them. The other questions simply boil down to plot, and the way I wanted the characters to interact and the story to pan out.
And one thing I truly hope you don’ add another character like a sister as if your doing that your changing the whole thing and her being born in itself is not meant to happen as the parent died originally just hope the author thinks about that and truly don’t add that daughter cause that only ruins a story I’v read the previous one it was good apart from having a sister for the Mc I don’t know why authors do that it’s pointless. That’ my additional view.
