What do u think would hv been the whole plot of SPN if Dean hadnot come back frm Hell in Season 4.......??????Also in those circumstances would u hv loved the show the way u do now........??????????

I jst wanted to know how the story would have moved on if Dean was not there.......Would Sam have joined the Evil side fr ever nd become a demon or not......Ofcourse no return of dean means no Cas..........So would u hv stopped watching the show.........??????????????
