Earth… is a prison. And I got out because I’m better than this place. I only came back to finish you off. You can’t manipulate me, Rose Quartz!... I’ve been fighting from the second I broke free from the Earth’s crust! Because of what you did to my colony, because of what you did to my planet, because of what you did to my Diamond! My Diamond... Your Diamond... Pink Diamond!
Steven, Amethyst, and Peridot hide behind a rock face while observing Jasper interact with a Corrupted Gem. Peridot suggests they head back to the temple and get reinforcements, to which Steven agrees. They realize that while they were talking, Amethyst was sneaking up to attack Jasper. Jasper is bullying the caged Corrupted Gem, telling her that "we all only get what we deserve," before turning around and saying, "right, Amethyst?" Amethyst is shocked and falls off the ledge before jumping up for a rematch. Jasper disparages her, telling Amethyst that she was "fated to lose the moment she came out wrong."
Steven runs to Amethyst's side and summons his shield while Jasper equips her weapon. Peridot attempts to show off her metal powers by moving a metal rod, but fails to do so. Amethyst picks up Steven and throws him to the side, telling him to not interfere with her rematch. She attacks Jasper, who is seemingly pushed back by Amethyst's new upgraded whips. The more Amethyst attacks, the more she realizes that Jasper is unaffected. Amethyst uses her spin dash technique while on fire to attack Jasper to no avail. Jasper easily kicks Amethyst away, who lands near Steven. As Jasper advances, Steven knocks down an Kindergarten injector by throwing his shield, which separates Jasper from him and Amethyst.
Amethyst claims she can't win, feeling that what Jasper said was true. Steven gives her a pep talk by saying they are both unique and that they have each other. Amethyst is reassured by Steven's words and they hug, fusing together for the first time. Jasper angrily questions who the fusion is supposed to be, to which they respond by saying that a Rose Quartz and an Amethyst make a Smoky Quartz, while also fusing Steven's shield and Amethyst's whip to form their yo-yo. Jasper is irritated, thinking that fusion is the only tactic the Crystal Gems have. Smokey Quartz casually counters that they have a lot of tricks before attacking Jasper with their yo-yo, pushing her back. Jasper uses her spin dash, but Smoky Quartz dodges. Jasper's attack breaks the cliff face where her Corrupted Gem army is held captive, which results in the Corrupted Gems fleeing.
Jasper sees the Snow Monster still trapped in its cell and attempts to run over to it while Smoky Quartz tries to stop her. Jasper eventually reaches the Corrupted Gem and fuses with her, forming a corrupted fusion. As Jasper's new fusion advances, Smoky Quartz spins their yo-yo to create a wind blast. The corrupted fusion is pushed back momentarily, but holds her ground and slowly advances forward. Smoky pulls out two more yo-yo's and creates a tornado. The corrupted fusion is lifted into the air where Jasper unfuses from the Corrupted Gem. She tries to fuse with the Gem monster again, telling her they can beat the Crystal Gems if they stay together. The tornado subsides and the pair fall to the ground, unfused.
The Corrupted Gem runs away, which prompts Jasper to lament that no one she fuses with ever wants to stay with her, followed by her laughing bitterly and then noticing the change in her arm. Smoky Quartz sees that Jasper's arm is starting to corrupt, so they unfuse and Steven offers to help Jasper, who declines. Jasper states that Rose would only take Gems who are at their lowest point, so that they can be made to feel like they mean something. She even points out Peridot, who she thinks was stripped of her status and her limb enhancers. She asks why she would side with Rose, and Peridot says while on Earth, she has learned things about herself, and Earth can set you free. Jasper still doesn't accept any of this and yells at Steven that he can't manipulate her. Steven, on the other hand, tells her he just wants to help.
As Jasper gets more furious and becomes more corrupted, she yells about how she's been fighting because of what Rose did to her colony, her planet, and her Diamond. Steven assumes Jasper is talking about Yellow Diamond, but the latter corrects him, screaming that it was their mutual Diamond: Pink Diamond. Jasper becomes fully corrupted and advances quickly on the Crystal Gems. However, Peridot pierces Jasper with a metal rod that was used to cage a Corrupted Gem, poofing her. Amethyst then bubbles Jasper and the trio head home. Amethyst says she doesn't want to do anything for a month, before groaning at the sight of Lapis, Garnet, and Pearl who have trapped the newly returned Ruby squad from "Hit the Diamond".

- A Cluster Gem, similar to one from "Nightmare Hospital", appears, fleeing from the Beta Kindergarten after most of the cages break.
- Smoky Quartz's yo-yo attack may be a reference to one of Ness's attacks in Earthbound. It may also be a reference to Killua from Hunter x Hunter, who also uses yo-yos as weapons.

- Jasper's corruption may be a reference to Tetsuo Shima's mutation from the 1988 film, Akira.
