This was really great. It was neat how Sam and Dean were both changed by being raised apart (Dean being really bad with people and Sam as minorly Sociopathic). How Sam didn't care about normal that much and how he wanted to have Dean above all other things for most of the fic. Although I am a bit unsure as to what other reasons he had for not wanting to shoot John. To me, part of the reason looked like he would have had to take over the world anyway and that Dean would have gone off the deep end.

I really, really liked it. Sorry that I'm not leaving a better comment.
