Earth 2 -- Four Weeks Ago
Chuck walks into a Radio Shed and over to a display of TVs. The clerk describes all the options for TVs and asks what Chuck is looking for, Chuck says he is looking for an audience, and begins to describes how he made the world, but wanted more so He made other worlds, as some of these worlds appear on the TV screens. Chuck realized that the other Sams and Deans in the other worlds don’t “spark joy” the way Sam and Dean of our world do; our Sam and Dean challenge, disappoint, and surprise Chuck. Chuck has an epiphany that he needs fewer worlds and begins destroying all his other creations.
Sioux Falls, Our World -- Present Day
Sheriff Jody Mills is looking at a dead steer, when Alex calls to say dinner is getting cold. Jody tells Alex that the cattle mutilation is not a monster but human cruelty. After hanging up, Jody sees someone in the barn and when she goes to investigate, she is knocked out by a hooded figure.
At the Bunker, Sam, Dean, and Castiel are discussing Jack’s deal with Billie. Sam is concerned that Jack doesn’t have a soul, has been in the Empty for months, and how they don’t have a sense of what he’s thinking or feeling about all of this. Cas says he trusts Jack. Dean agrees that he thinks Billie’s plan is the way forward and that even if she isn’t telling them the whole plan now, Billie's strict adherence to rules and order makes him feel like he can trust her.
Meanwhile, Jack is in the library and notices the Sam, Dean, and Mary’s initials carved into the table, and runs his hand across Mary's. Jack wanders into his bedroom and Merle, a reaper, appears. Jack has been “praying” to Death, but as she’s busy, Billie sent Merle to find out what Jack wants. Jack wonders why Billie hadn't helped him earlier, when he was captured by the Grigori. Merle asserts that Billie knew that Jack could handle the Grigori and that Cas would save him. Merle tells Jack that he needs to follow the rules: lay low, wait for instructions, and don’t use his powers. Jack agrees. Sam walks in and and tells Jack how glad they are he is back.
Dean and Cas are having a drink and discussing Kelly Kline’s faith in Jack’s goodness. Cas shares how he was so lost after Chuck killed Jack and how he just knew that Jack’s story wasn’t over. They toast to Cas being right, with Dean proposing a toast to revenge, too. Dean is excited about the possibility of Chuck being killed by his grandson and how fitting that is. Suddenly, Jody calls and tells Dean she’s in trouble and to come get her or she is dead.
Sam and Dean arrive at the barn where Jody is being held. As they release her, Sam and Dean are attacked by Dark Kaia. She asks about her spear and Dean's promise to get her back to her world, “The Bad Place.” Dean tells her that after she attacked their friend, the deal was off. With Jody’s help, they subdue Dark Kaia and find out she wants to go back to her world because it’s dying. Dark Kaia is dreaming about her dying world through the eyes of Kaia who is alive and stuck in the Bad Place.
Back in the Bunker, Cas and Jack are playing Connect Four when Sam, Dean, Jody, and Dark Kaia return and after chaining Dark Kaia to the kitchen table, they begin to search the lore and check magic supplies for a way to get Kaia back without using Jack’s powers. Jack’s finds a spell, but one of ingredients is the liver of a mandragora. Sam and Dean chuckle and tell them that their father killed the last mandragora and recounted it in his journal under “A Hunt in Fargo.” Jack leaves to help Jody and Cas look through the stores in the Bunker; Sam and Dean realize they are stuck without angel grace.
As Jody inventories magic ingredients, Cas leaves a voicemail for Sergei. Cas asks if Jody has told Claire about Kaia being alive. Jody tells Cas that Claire is out of cell phone range in Yosemite, loved Kaia and has spent years looking for revenge. Jody knows that Claire would do anything to save Kaia, but there’s no time to get her involved and she’s hesitant in case a rescue fails. Jack has overheard this whole exchange and goes to talk to Dark Kaia. Jacks apologizes for not being able to do more, but Dark Kaia angrily rebukes Jack. Jack asks why Dark Kaia came to this world, she tells him how she envied Kaia and her “peaceful” world, but Dark Kaia has realized she doesn’t understand this world; she pleads for Jack’s help. Jack dreamwalks Dark Kaia and is able to see Kaia in the Bad Place. Jack tells Sam and Dean he will save Kaia because he saw that she’s running out of time. Merle appears to remind Jack of the rules and that risking their plan to save one life is “Winchester dumb.” Merle threatens to tell Billie; but Jack calls her bluff and tells Merle to go tell Billie, but that while she’s gone, he’s going to open the rift and save Kaia. Jack convinces Merle that not telling Billie and working with them to save Kaia is a better plan than Billie finding out that Jack went ahead with saving Kaia on Merle’s watch. Merle agrees and says the first step is to temporarily fix the cosmic warding in the Bunker that Amara destroyed.
After they upgrade the warding, Sam and Dean pack for going through the rift. They acknowledge that they are taking a risk, but that it also feels good disobeying cosmic entities and doing the dumb, right thing. Cas asks Jody to stay behind as Hhe is concerned that if something happens to Jody, Claire will be devastated and never recover Jody reluctantly agrees. Jack opens the portal and Sam, Dean, and Dark Kaia go through.
In the Bad Place, Sam, Dean, and Dark Kaia are surrounded by creatures with red glowing eyes. Sam and Dean prepare to fight, but Dark Kaia stops them; the creatures are not after them but are afraid of what’s happening in the world. They find Kaia in Dark Kaia’s hut, and after embracing Dean they prepare to leave. Dark Kaia chooses to stay behind, telling everyone she never belonged in Kaia's world, and should never have left her home. After Sam, Dean and Kaia back it back to the Bunker, a rolling, thundering fog with lightening washes over Dark Kaia and her world.
After changing into some of Jack’s clothes, Jody invites Kaia back to Sioux Falls to live with her. Kaia asks is Claire will be there and Jody says “soon”J before the two leave.
Merle thinks the warding worked and kept Jack’s use of his powers off Chuck’s radar. From out of nowhere, Billie appears and kills Merle with her scythe. Billie is disappointed that Jack is already bending the rules, telling him and the Winchesters how she sees the big picture and that saving one life is nothing in the grand scheme. Billie reveals to them that all the worlds, but this one, are dying. Billie tells them that when she became Death, she inherited Death’s knowledge and Death's Library. She divulges that God has a book in the library that says how He will die. Due to Chuck needing to build himself in the framework of the universe for it keep going in his absence, it is his one weakness. Questioning why Chuck would write his own demise, Billie tells them that God didn’t write his own death, the books write themselves. The details in each book are only known by Billie and whoever she lets read them. She informs every one that Jack is in God's book, as are Sam and Dean who are the messengers of God’s destruction.
In the Radio Shed, Chuck is watching the dying worlds on the wall of TV screens. Chuck gets up to leave and the Clerk asks if he and his world will be spared. Chuck tells him it will be fine and leaves the store. In the sky, with two moons, flaming meteors falling to Earth, one landing directly on the Radio Shed.
