Sam and Dean respond to a distress call by Jody Mills, who has been kidnapped by Dark Kaia. Meanwhile, Chuck is destroying alternate universes he created one by one.
Tropes
- Alternate Universe: Aside from the Bad Place, Chuck spends his time on Earth 2, a reality where Radio Shack is called Radio Shed and Hilary Clinton is president.
- Colony Drop: Chuck destroys one of the alternate universes this way.
- Continuity Nod: Billie claiming that God has a death book in her Reading Room is a reference to how the previous Death claimed in "Two Minutes to Midnight" that he would eventually reap God himself (complete with flashback to that conversation).
- Depopulation Bomb: Dark Kaia dies alongside her entire world when it is destroyed by Chuck.
- Earn Your Happy Ending: For Kaia who has spend her whole life tormented by the Bad Place and then got stuck there for two years she is rescued just in the nick of time as that world collapsed and can now live her life free from that torment. And if the end of the episode is any indication she and Claire may get to act on their shared Ship Tease when they see each other again.
- Expendable Alternate Universe: Literally. It's revealed that the primary setting of Supernatural is the first world Chuck created, so it is literally the "main universe". Everything else (the Apocalypse World, the Bad Place, etc.) are backups/testing grounds that Chuck can casually dispose of if he no longer feels amused by them.
- Face Death with Dignity: Dark Kaia ultimately decides to stay in her dying world, and as its end hits she stands still and closes her eyes.
- Hoist by His Own Petard: According to Billie, in order to be capable of manipulating reality Chuck had to insert himself into its makeup, which also added him to Death's library, allowing her to plan how to kill him.
- Hope Spot: In one alternate universe, Chuck promises to a hapless shopkeeper that he won't destroy his world. Right after he leaves, the camera cuts to the sky, where asteroids begin raining down.
- I Love You Because I Can't Control You: In a twisted way, Chuck is obsessed with Dean and Sam of the main world because he can't make them obey him, unlike their counterparts in the backup worlds.
- Leaning on the Fourth Wall: During his Motive Rant at the beginning of the episode, Chuck mentions "failed spinoffs", an obvious reference to the Supernatural creators' prior attempts to spin off from this show, Bloodlines and Wayward Sisters (especially the latter, as the Bad Place storyline introduced in its Poorly Disguised Pilot comes to an end here).
- No One Gets Left Behind: When they find out that Kaia is still alive and is trapped in the Bad Place, which is in the process of being destroyed, Team Free Will decide to find a way to rescue her especially Jack who feels guilty for getting her caught up in all this.
- Not Quite Dead: It is revealed that the real Kaia Nieves is still alive. She was merely injured when her dark counterpart stabbed her and has been spending the last two years in the Bad Place.
- Omnicidal Maniac: Chuck has started destroying The Multiverse, so that he can focus on bringing about Sam and Dean's final defeat in the primary universe.
- Pass the Popcorn: Chuck is eating junk food while witnessing the dying worlds being destroyed by his own hand.
- You Have Failed Me: Rare (sort of) heroic version as Billie puts a scythe through her reaper Merle for allowing Jack to use his powers.
