I read on wikipedia - and correct me if I was misinformed - that Supernatural got cancelled because of the coronavirus outbreak. As if it wasn't ruining enough of the world already.
So, we left off on Galaxy Brain where Billie said a critical detail on how the final battle might end. But we aren't given exact details on how it will go down.
What's your headcanon as to how it ends? Since that's the best we can go by now. How does Jack become powerful enough to kill God and how are Sam and Dean involved?
Or did they reveal the ending somewhere now that they know the final episode will never be released? If so, please show me so I know how it ends, I don't want to become a ghost when I die from the state of panic the world is in within a few months tops.
