i really like the little detail that the fairchilds aren’t a real family, but rather just a name, whereas the lukases are a biological family, but deeply disconnected from each other. the vast sees no inherent value in names, they hold no meaning and can be given away like a gift to anyone it wants to mark. the lonely sees no value in family bonds, they can be severed at any indication of disloyalty, but are still preferable to chosen bonds.
