Whomever wrote the headline for that article is a lazier writer than people claim the show runners to be and is just looking for clickbait. It's clearly *not* what he said : "He said: "How will it all end? The same ending as the show? Different? Well... yes. And no. And yes. And no. And yes. And no. And yes."
