This is it, folks, the very last SUPERNATURAL season finale. At this time next year, we’ll be watching the show’s series finale. And we open the season 14 finale right where we ended the penultimate episode — Jack has escaped from the box and he’s *furious* at the Winchesters and Castiel. After a tremendous flexing of his power, he disappears out of the bunker, leaving the boys and Cas on the floor, and the room totally destroyed. The trio quickly deduces that Jack has “levelled up” and his powers were too great to be contained by the box.
As Castiel laments, again, that the brothers shouldn’t have put Jack in the box, Dean is still angry that Cas kept the extent of Jack’s problems from them. He declares that the brothers will take care of Jack, who he calls just another monster. Castiel storms off and Dean tells Sam he understands that this is hard for both of them, but they need to do the tough thing here because it’s the right thing to do.
Outside in the world, Jack seems angry that everyone around him is lying to other people and he manages to almost freeze time for a moment. In other words, his powers keep growing. And we soon see that Jack’s order for people to “stop lying!” has tremendous repercussions. As the brothers head out to find a lead on Jack, Sam gets Rowena’s buy-in for their plan, as insane as it apparently is. Soon they have arrived at Mirror Universe, a company that builds facial recognition software, which Sam wants to use to find Jack. But soon we realize that Jack’s declaration means that *no one* can lie anymore. Not in that town, and not anywhere else. Sam realizes that Jack is responsible for all of this as the people in the company descend into chaos.
Meanwhile, Castiel has sought out a demon to take him to Hell. But she’s not in a giving mood and shuts the door on him. Enter Chuck (a.k.a. God), who quickly surmises that Castiel is “screwed”. He explains that Castiel had successfully called him in a previous episode and now he’s here to deal with Jack, who Chuck labels as a “problem”. They quickly turn up at Mirror Universe to witness the chaos there, while Castiel calls out for the brothers. As Chuck tries to sing about where he’s been, Dean furiously grabs his guitar and smashes it, causing Chuck to scream out “don’t!”. He quickly transports them to back to the bunker and says he’s been connecting with Amara, who is now in Reno, while he has returned for Jack. He’s only back now because Jack is apocalyptic, which is a situation where he feels he has to intervene.
“Can you fix it?” Castiel asks Chuck about their current truth problem. Chuck quickly snaps his fingers, allowing people to lie again, and essentially resetting the last few minutes we witnessed. When asked if Chuck can stop Jack, he says no, but they can….by using a gun he has gifted them. Chuck tells the others that this gun can kill Jack, but it doesn’t have bullets. Because the universe is all about balance, it doesn’t fire bullets. Instead, it sends a multi-dimensional blast that will level the playing field, so to speak. In other words, if you “shoot” someone with it, you’ll also die.
Cas doesn’t realize why they’re talking about killing Jack because he wants Chuck to return Jack’s soul. But Chuck says souls are complicated, even for him. Dean insists that this is the only way, so Cas needs to get on board or walk away, and Cas chooses to walk. Shortly after, Sam finds Dean drinking in his room and tells his brother that they still have a choice. Dean doesn’t need to pull the trigger like Sam knows he wants to do. Instead, Sam says they should try to save Jack. Sam also points out that he originally brought Jack back because he’s family, and Jack burned off his soul to save both of them. Sam refuses to tell Dean he’s okay with losing both Jack and Dean at the same time because he’s already lost too much.
Meanwhile, throughout all of this, Jack returns to speak to his grandmother, who tells him she doesn’t want to talk. She admits that she knows he didn’t work with Kelly and she believes her daughter is dead. She demands to know what Jack did to Kelly, and he erupts at her before quickly leaving, but we don’t yet see what he did to her. Soon after leaving the bunker, Castiel takes his truck and stops at a park, furious at the situation, while Jack appears behind him and Cas hugs him. Jack explains what he did with the lying situation and then says he went to visit his grandparents. He admits he no longer feels anything and tells Castiel that he showed his glowing eyes to his grandmother and then quickly departed, shocked at her horrified reaction to him.
Back at the bunker, Sam talks to Chuck about alternate universes, who tells him that there’s all sorts of other strange dimensions (including one without the colour yellow). Sam wants to know if God created and then discarded these other worlds and whether he’s doing the same to their world. But Chuck says that this version of Sam and Dean are his favourite out of all the Sams and Deans in the multi-verse. Chuck also admits that he does watch them when he’s not with them because they’re his “favorite show”, but Sam is furious that they always have to step up when the chips are down. “Because you’re my guys,” Chuck explains. Sam is shocked to learn that Chuck is actually frightened of Jack and Chuck admits he knows where the boy is and that Dean is already gone.
At the park, Jack and Cas are sitting on a bench and Castiel says they need to go somewhere safe where no one can find them until they can fix this. But Dean has already arrived to deliver his brand of justice. Castiel stands up to face Dean, while Dean tells him to step aside. Cas tells Jack to run, but Jack says “I won’t run anymore” before flinging Cas away with his powers. Then Jack kneels on the ground and waits for Dean to shoot him, while Sam peels up in another car. Sam is crying out Dean’s name as he runs up to the others, while Dean and Jack stare at another and Jack says Dean was right all along. “I am a monster” he says sadly.
Sam begs a recently appeared Chuck to do something, and when he doesn’t Sam accuses him of “enjoying this”. Dean cocks the gun as he continues to stare at Jack, but he soon lowers the weapon and throws it away.
“No, pick it up!” Chuck orders Dean. “This isn’t how the story is supposed to end. This is Abraham and Isaac, this is epic!” Sam realizes that Chuck has been playing them “this whole time. Our entire lives. This is all you, because you wrote it all.” Chuck tells Dean that Sam is crazy and if Dean shoots Jack, he’ll bring Mary back. But Dean refuses. “My mom was my hero and I miss her. I’ll miss her every second of my life. But she would not want this. And it’s not like you even really care, because Sam’s right.” Sam and Dean want to know where Chuck was when they were suffering and losing people they loved. “When does it end? Tell me!” Sam asks God.
Dean insists this isn’t just a story, this is their lives. “So God or no God, you go to Hell.”
“Have it your way,” Chuck says just before he snaps his fingers, causing grace to shoot out of Jack. Chuck flings Dean away as Castiel kneels by a screaming Jack and Sam….
Sam picks up the gun, yells “hey, Chuck!” and fires the weapon.
But Sam didn’t actually kill God, he just shot him in the shoulder, causing Sam to also get shot. “Fine, that’s the way you want it?” Chuck says to them. “Story’s over. Welcome to the end”. Meta, indeed, as we head into SUPERNATURAL’s final season.
Night appears instantly, as Castiel stands over Jack’s dead body. Moments later, we see Jack wake up in the Empty, where the black gooey entity faces him and Billie appears behind him, saying “we should talk.”
Back on Earth, an earthquake starts, and the souls of beings in Hell start flying up into the sky. On the side of the road, a Woman in White appears. At a children’s birthday party, a killer clown shows up at the door, while other demons and monsters appear in people’s homes. Zombies show up in the cemetery.
In other words, Chuck has very literally unleashed Hell on Earth.
The Winchester brothers and Castiel prepare to face off against the zombies, as they close in on them.
SUPERNATURAL has been renewed for a fifteenth and final season and it looks like they’ll really have to face “the end” beginning in the fall.
