i honestly think its a prophecy and only Kevin the prophet can read it, and the winchesters will track him down so he can read it which will have those 3 things that can destroy the leviathans which will be tracked down in there will be blood episode, dick wanted to destroy it because its the only thing that can kill him as of now, and i bet one of those things that can kill him is a new supernatural who is much more powerful than a leviathan or perhaps when they are killed, it somehow activates this new supernatural to come and would have to deal with that along with crazy castiel, meg and crowley, i would make them the demon version of bonnie and clyde and vengeful ghost bobby along with this new supernatural big badass in season 8 and finally top it with a storyline that Dean has literally had enough and quits hunting which makes things 10 times worse
