According to spoilers, more about the world of god tablets and the angels and demons will be shown in s8 but that makes me wonder if Mephistopheles will appear. Now you're asking who is he? This is him:

According to mythology he is a representation of the devil but not actually him. Oddly I wouldve thought the character Alaistair wouldve been mep. Obviously not, so maybe he will come this season instead to work with crowley. And metatron, the angel we heard about will come as well to help castiel and the winchesters locate the remaining word of god tablets before crowley and mep do. What do you think?
