So do yourself a favor and keep your mouth shut. That will be all.
Steven and Greg are taken hostage by an Amethyst guard and are put into a room full of Quartz Gems. Amethyst has been captured as well. However, it was revealed to be a cruel humorous trick by the Amethyst guards that Amethyst planned to do.
Amethyst explains that all of the Quartz Gems here are from Earth made in the Prime and Beta Kindergartens. Amethyst also found out her official designation name is "Facet 5 Cut 8XM". The Quartz Gems celebrate until Holly Blue Agate comes in and orders them harshly to their stations as Blue Diamond had returned. Amethyst tells Greg and Steven to run away.
Steven and Greg run off and enter Pink Diamond's throne room which contains an uncountable amount of bubbled gemstones. Steven begins to shed tears, indicating Blue Diamond is near. Blue Diamond comes in with Blue Pearl and continues to grieve. Yellow Diamond enters with her Yellow Pearl shortly after, unbeknownst of Blue Diamond.
Yellow Diamond wants to bring Blue Diamond back to "reality", stop her from grieving, and destroy the many bubbled rose quartzes in retribution for the one who shattered Pink Diamond millennia ago. Blue Diamond wants to preserve the memory of Pink Diamond by keeping the bubbled Gemstones, her Zoo, and the Earth. Yellow Diamond wants her to stop and put the entire debacle behind them. It proves more difficult than it needs to be, so Yellow Diamond tells her Pearl to help sing a song to make Blue Diamond feel better.
Holly Blue, Ruby, and Sapphire enter the room, and Holly Blue greets Blue Diamond nervously but quickly realizes Yellow Diamond is there as well, which makes her try to flatter both diamonds in an attempt to gain favor. The Diamonds want a quick explanation for her presence, so she explains that "your [Blue Diamond]" Sapphire has completed her special delivery.
Blue Diamond has never asked a Sapphire to make a special delivery. Sapphire, however, rebuttals with her precognition of Blue Diamond's desire for more humans for the zoo, convincing herself to act accordingly. Blue Diamond admits it is true but knows there is not enough time to preserve all humans. Yellow Diamond asks Sapphire if the Cluster has formed yet, which it has not according to Sapphire, proving there is still time. Yellow Diamond dismisses the group and tends to Blue Diamond afterward.
Holly Blue is relieved all went well and is also jubilant to see Yellow Diamond in person and see the zoo has not become a forgotten piece of Gem history, making it all worth it to her for how much time she has spent preserving such a remote location with Quartz Gems. Nothing could have spoiled her happiness until she finds out, just after saying so, the captives humans Steven and Greg are witnessed climbing into the Roaming Eye.
Holly Blue blames the Amethyst Guards for their incompetence and proceeds to capture the humans herself with a whip until she is stopped by Ruby and Sapphire fusing into Garnet and catching the whip. Pearl then cuts the whip, and Amethyst spins around Holly Blue to tie her up. Garnet then materializes a gauntlet but proceeds to punch Holly Blue Agate with her bare hand in a display of mockery, which then causes Holly Blue to fall over and be laughed at by the Amethyst guards. The Amethyst guards wave goodbye to the Crystal Gems and Amethyst declares them "Famethyst for life".
Holly Blue threatens to report everything to the Diamonds, but Pearl gives her a reality check on her incompetence and bias, telling her that reporting the event would only jeopardize her status. This silences Holly Blue as the Crystal Gems exit the Zoo.
The Crystal Gems exit the Zoo set course to return to Earth. Steven apologizes to Greg for getting him into this because he wanted answers. Greg asks if he got what he was looking for and Steven replies that he did; he got his dad back.
