I think you should give Will more credit than that. He's a really smart guy, and I think that his brains and wits will keep him safe, more or less.
Thanks for sharing that. Not only was it interesting, it hit on some of the things I was trying to raise here. I think that if Will and his parents are that pig-headed and stubborn, a rift like you describe is entirely possible. I do think, though, that they would ultimately reach an epiphany before it got as bad as things did with your family, at least over the long haul.
I think that it helps to think of this as a massive power struggle. In that regard, Brad and Robbie are probably completely clouded by the need to bring Will into line. They're probably thinking that he's turning into a college student at 14 (with the drinking on the trip, and at Stanford), and that in order to prevent him from totally becoming a burnout, they have to snap him into shape. So where did I learn to channel these people who lose sight of what's important? Well, I've written Will to be a lot more responsibly than my own son, and I've written Brad and Robbie to be a lot worse than I was, but I actually lived something like this, although I didn't hire a marine. That's the big point of departure here, but it makes the story more fun. :-)
To be honest, I'm not sure how I would even tie that together, with some big overall dramatic purpose.
I can see that as well. I do think that JJ could have done a better job with it, though. He could have enjoyed it a little more subtly.
