Something about that finale just doesn’t sit well with the fans.
Listen, there are so many conspiracy theories circulating about the Supernatural ending, you’d think fans would get tired of talking about the same 40-minute episode for three years. But the finale was so unexpectedly bad, it’s on par with the Game of Thrones flop ending—and that’s saying something.
There’s this theory that might explain the lack of some key characters (or rather, their presence in absentia), abysmal final moments for the main characters, and the version of heaven for Dean Winchester that included his father of all people. It doesn’t seem right, don’t you think?
Well, this could all be chalked up to Chuck ultimately winning, a theory that is called Chuck Won, and fans that believe in it call themselves Chuck Won Truthers. It basically claims that Chuck was not defeated in Season 15, Episode 19; he survived and tricked everyone into thinking that he died.
Why do they believe it? In Episode 4 earlier, Chuck showed Becky the ending he felt the Winchesters deserved—with the tombstone that read “Winchester”. Becky called the ending “horrible” and said it would make fans miserable. Chuck was very happy with that reaction, apparently; he wanted to elicit some emotions, and the terrible ending would do it perfectly.
That ending is the one we actually got, and we were not amused.
The show goes around in circles. Every episode ends with brothers learning something important, and then doing so again, and again, and again, fighting Monster of the Week, dying so the other could live, saving each other, making friends, betraying them, and on and on it goes. Wouldn’t it have been wonderful to break it all?
From the first episode, we establish that Dean Winchester is a fighter. He didn’t want to die so young, but he thought he would—ultimately proving there’s no such thing as free will, something the characters struggled with throughout their life. They fulfilled Chuck’s prophecy: Dean died, Castiel was barely mentioned, forgotten, and Sam lived his life (happily?) with some random woman.
It explains the unsatisfying ending perfectly: the evil was not defeated. It lurks, unseen, among all of us, and every single thing is predetermined, written in the stars.
To think we could’ve had it all: give Dean that apple-pie, white-picket-fence life—with Cas, with Lisa, whatever—and have him retire from the hunts, visiting Sam and his wife (and not the blurry-faced; Eileen, preferably) with his spouse. But it couldn’t happen. Not in Chuck’s world.
