re: Supernatural series finale

I always thought Dean would survive because he was Michael's chosen vessel. He was the good one. Sam had the demon blood and was Lucifer's vessel. I liked the good brother/bad brother dynamic they had but that eventually disappeared over time.

Sam could have just told his son the tattoo was some kind of family symbol. The kid might not have known what it meant. I do think it would be irresponsible of him to give up hunting and let monsters keep killing people though.
