Changes

While Castiel and Jack are playing connect four Connect Four when Sam and Dean return with [[Jody]] and [[Dark Kaia]]. She reveals that [[Kaia Nieves]] is alive in [[The Bad Place]] and they start looking for a way to reopen the rift without using Jack's powers or grace. However, their Their search only uncovers a spell that requires the liver of a mandragora, which became extinct years ago when [[John]] killed the last one on in a hunt in Fargo. Later, Jack overhears Jody and Castiel's conversation about [[Claire]] searching for revenge for two years for Kaia's presumed death. He visits Dark Kaia, who initially acts coldly towards him, but he says he wanted to help her since she was in pain over her powers. Dark Kaia tells him that she wanted to come to Kaia's world because it looked peaceful, but she doesn't know where she belongs in the world and pleads for his help to take her back. Jack agrees to dreamwalk with Dark Kaia to check in on her.

Jack tells Sam and Dean that he used his powers, but Merle interrupts before the conversation could can continue. She threatens to tell Billie if he uses his powers again, but Jack dares her to go and says he'll use his powers anyway. She threatens to stop him, but Jack is unafraid and tells her that she could either deal with whatever Billie does to her for failing or help them find the best way to open the rift so she never has to know. Merle reveals that the cosmic-level warding used in the Bunker was weakened when Amara invaded. She agrees to help restore it for a time, but she needs Castiel to help power it up. When they restore the Bunker's warding, Jack opens the rift to the Bad Place and Sam and Dean travel through with Dark Kaia. They manage to retrieve Kaia, but Dark aia Kaia stays behind, choosing to die with her world.

Kaia puts on some of Jack's clothes and leaves with Jody, wanting eager to see Claire again. When the Winchesters thank Merle for her help, she is abruptly killed by Billie for disobeying her orders. She scolds Jack for breaking the rules so soon after his resurrection, but she and explains that they're playing a big game and she sees the big picture. She explains that when Castiel killed her, she inherited Death's collective knowledge and his library. In the library, everyone has a book detailing how they die, even God. She explains that in order to create other worlds, Chuck had to integrate himself Himself into the multiversal quantum construct to make sure the Winchesters' world kept operating in his His extended absence. He, in turn, created his His greatest weakness, : that he He would one day die like everything else. Billie reveals that [[Team Free Will 2.0]] are the messengers of God's inevitable death.
