You're very welcome! I'm glad the style was okay (it was slightly strange to write).

I thought the Lost Brother was Dean and that the Chosen One was Sam

It would seem that way, wouldn't it? Dean seems to be the one chosen to be the "free choice" man and Sam is very much John's son, esp. after what we saw in "JtS". It's interesting that their roles can be looked at in different ways, that different aspects of their personalities satisfy both descriptions.
