Well according to the preview for the next episode, it shows Dean in the new supernatural handcuff. So maybe they will start to attack the cities residents but likely only a small amount will be affected. So maybe that is why John comes back to deal with AU Michael possessing Dean. Also I can’t wait to see how Sam and Dean will tell Adam is in the cage and never tried to get him out to John. Unless the John coming is an AU version like Bobby.
