SEASON PREMIERE: For most series, starting Season 13 might be considered an unlucky omen – but for Supernatural, it fits right in. And Season 13 doesn’t waste much time getting the demon-fighting brothers together, and pointed in the same direction. But I’m not sure about all the other alternate dimensions that might exist on this show. In one alternate dimension, Sam and Dean may still be separated, and their mother is alive and isolated there. At least, that’s what I think is happening. Once these multiple-dimension story lines start spinning, whether it’s Supernatural or Mr. Robot or The Flash, I’m guessing there’s a TV critic, in some alternate dimension, who looks just like me, but understands it all.
