I'd only add to that -- don't know if someone already did in comments, if so, sorry for reiterating -- the yearly excursions to see the petroglyphs. The "I remember the first time I beat my father to the summit". The fact that where Danny and majority of US boys had baseball games with their Dads, Steve had deep sea demolition classes extreme survival trips in Hawaiian mountain range. That's their relationship in a nutshell. :)

In other words I think your analysis is spot-on.
