This exact behavior reminds me of my own mother. Having come from suffocating parents that isolated me from everything, I'm extremely concerned for her child. It has taken me years of therapy to feel like I can even begin to participate in society like a normal person. Their escape home in the woods that's away from everything is going to start to feel like a prison to him once he's older. And I only see Kristi becoming more and more suffocating as time goes on. To the point where I doubt she'll even allow him to have friends or even have a phone or internet access once he's older. I foresee her trying to keep him "young" and simple minded so that he doesn't ever question leaving. It's a different kind of abuse and being a personal victim of it myself, I wouldn't wish it on anyone.
