Has anyone else had the phenomenon of grandchildren (or great grandchildren, etc) joining defeated nations because they have blood ties to them and then becoming the King or Queen?  Ive had it a few times and ran into them.  They don't move, are usually stuck on some other nations capital, but you can interact with them the same as if they were a neutral faction.  When you start the dialog with them, there throne room is empty, but you can trade items and make treaties.  I'm curious if they are capable of more, like re-founding of their kingdom?  If they could, that would be bad ass.
