The xuncledud will always be an oddity to the kids. They will never feel his is family and will always remember the pain shared by all in their home at xw's exit.
That will always be the elephant in the room.
It will for a long time prevent the kids from having a complete connection with xgrandad and xgrandma, even though they may still technically be grandad/grandma.
The thing they will remember the most, that will define you the most in their hearts and minds is that you don't speak badly of xpeople. When these new soulmates transition to just being two people that gave in to adulterous passions, you won't need to tell the kids anything. They are incredible creatures and will know more than they want to remember.
