Bismuth (Uzo Aduba), one of the original Crystal Gems, is accidentally discovered by Steven inside of Lion's mane. Upon being released, she is welcomed back with open arms by Pearl and Garnet, and Amethyst (despite not meeting, nor being told about her) quickly warms up to her company. However, Steven soon notices that Bismuth's outlook of the rebellion is radically different from the other Gems' when she shows eagerness to re-ignite the Gem War with an unethical secret weapon.
Steven and Amethyst visit Lapis Lazuli and Peridot at the barn to see how they're doing. While showing them around the new barn, Amethyst is uninterested due to constantly thinking about losing to Jasper the last time they fought. So, to cheer her up, Peridot takes her and Steven to Jasper's birthplace â€“ a heavily rushed and poorly made Kindergarten in the middle of a desert to see if Jasper has any flaws based upon her hole.
Steven, Amethyst and Peridot encounter Jasper at the Beta Kindergarten. To fight off her and a corrupted Gem monster, Steven and Amethyst fuse into Smoky Quartz (Natasha Lyonne) and Peridot attempts to use her metal powers.
24. "Back to the Moon"
The dispatch team of Rubies return to the barn still searching for Jasper. To try and get rid of them once again, Amethyst shapeshifts into Jasper. However, things get awry when the Rubies want her to contact Yellow Diamond at the Moon Base with Steven, Garnet and Pearl as her "prisoners".
After being sucked out of the Moon Base's airlock, Steven and the Rubies are stuck floating in the middle of space. To stay safe, Steven puts himself in a bubble and runs into one of the Rubies in the process.
