It'd either have to be a full season of Sam without Dean (but at least he's got Castiel, Jack, Mary, Alternate Bobby, and probably occasional help from Ketch, Alternate Charlie, and Rowena), or else Michael will have to find a new vessel. Or be sent back into his old one like Lucifer was in Season 12.
