Excellent!!!
Jack's flashforwards were powerful and speak to the force of context and how it influences people. I was reminded of the crisis I had after graduating with a bachelors degree and entering "real life." In college I knew who I was because I knew what to do in my familiar place. I knew how to be involved, how to stay active, how to lead, what my role was etc. When my context was no longer accessible, I had hard time adjusting (although I did not resort to oxycontin).
Lost has tapped into the power of context to influence roles in a person's life. In fact, that is what Lost has been about for three years - context.
In large measure, it is also about conversion. Make whatever religious connections you want, the show is about conversion.
Conversion and context. Change a person's context and they must convert in order to survive. After college, I had to convert. After getting into a committed relationship, I had to convert. After having children I had to convert.
From a religious perspective, including people into your context is powerful. Should they accept your acceptance, that is a sort of conversion.
