I was expecting good mom's demise a chapter earlier, while Gramps was in hospital still. At times characters seem to be difficult to portrait in a consistent way, or they don't fit well into the intended further story development. So they have to die some way or the other. At least in WA it happens a lot. Also boys abandoned, orphaned, in an case very mature very early and making big decisions - and big fortunes- without any real experience/training beforehand, are a recurrant theme.
Even though I am by now used to the MO of such main characters, Anton's decision making still baffles me at times. How little he consults with the parties involved. Like making arrangements for distance education for Simon, only talking or rather just informing Jasper an hour earlier. But not Simon. Or buying the flat in Perth. Can he even do that all by himself, not being18? Or at a whim making legal arrangements for Vic and Rita to only receive shares in an unstable, new business venture instead of already agreed payments??? Without even talking to them?
Be it arrogance or hubris, this lack of humility, empathy...whatever is an annoying trait of our little hero.
