Re: 6x13 - Unforgiven
Every since the god's episode I just figured the different religions were like the episode in season 1, were we first meet the ghostfacers. The symbol were if enough people believe in it, it becomes true which is why Satan is powerful but there are other things more powerful, like death it's self. Things that didn't have to be brought into existence.
But honestly this show was set up and made to be a 5 season show everything built up and all the mythos was leading to the season 5 finale, minus the last 5seconds of the finale. So anything that comes next is just more time with the characters and lore, and just look at it like the shows over this is just bonus...only way not to go crazy it seems.
