I'm starting to wonder if WAV actually cares about culture at all. He certainly wasn't old enough to take any English culture with him when he left the country; he spent almost all his childhood and a good slice of his adult life in Australia. Genetically he may be a repatriate, but culturally he's quite obviously an immigrant. So maybe it's not culture that determines where people ought to live, in WAV's world, but where your genes come from.
