I don't really care to see Ben and Lisa again unless it was to find out that she lied the whole time and Ben really is dean's bio son. His reason for wiping her memory made sense but I agree that they would still make good leverage for enemies. I really hope god doesn't come back in season 16. He's annoying af. I would like to see jack with more developed powers and probably would watch 60 seasons of supernatural since it's the best soap opera ever and they can do whatever they want in of life death etc. I'm interested how things fared under jack's powers. Did he ever create more universes? Did he repopulate the angel ranks?
