Supernatural has threatened to destroy the world time and time again; if Supernatural continues beyond Season 14, I expect the world would wind up on back the verge of destruction.
Throw in the mass of hunters that Sam recruited during Dean’s first stint as Apocalypse World Michael’s host, and the status quo is just different in Season 14 than in years past.
There are just enough differences in how the characters handle themselves in Season 14 (as well as the unique nature of Michael’s threat and Billie’s hints) that I genuinely don’t know what to predict about what’s in store.
