okay and the episode be pretty much all excellent from season 1 and 2 and this episode be well execute . jensen and jar be exceptional actor and be always surround by wonderful counterpart and whether a guest appearance or a regular . my take while sam and dean mother be some sort of part supernatural be and be kind of hide out from whatever past she have . the yellow eyed demon finally find her and corrupt sam because he be an infant and jared be old and more self aware . in the final episode jar will somehow trap the demon and be force to make a deal where the demon will bring sam back and dean will let the demon go . or and sam real father be the yellow eyed demon and which would make for a really bad cliché . i have faith in the writer that they will not make this show just another cliché . peace and slackwoo .
