Amara, Michelle, and Trista watch Hotaru's every move, suspecting that Hotaru is a target of the Heart Snatchers, but Raye thinks she might be the Sovereign of Silence. Amara, Michelle, and Trista soon realize that she is, because the Heart Snatchers chose her to be.
Mimet targets Thomas for his Pure Heart.
Serena and the others meet Trista at the planetarium. Trista tells them that she, Amara, and Michelle are there to protect the world from the Silence, and shows them Raye's vision through her crystal ball. She says the Sovereign of Silence will reveal herself when Saturn eclipses the other planets.
Mimet releases her Daimon, Uchoten, who begins attacking people. The Sailor Scouts arrive at the scene, so Uchoten fights them instead of taking Thomas's Pure Heart. She uses her power in an attempt to make the eclipse come faster, but Tuxedo Mask stops her. As Uchoten continues her attack, the symbol of Saturn appears on Hotaru's forehead, indicating that she is a Sailor Scout. Sailor Moon uses the Purity Chalice to transform into Super Sailor Moon, and destroys Uchoten with Rainbow Moon Heart Ache, leaving only a galaxy globe model.
Sailor Uranus, Sailor Neptune, and Sailor Pluto attack Hotaru, but Rini jumps in front, and Sailor Moon saves them both. The three Outer Sailor Scouts tell the Sailor Scouts that Hotaru is Sailor Saturn, the Sailor Scout of Destruction, feared by all, and that if she awakens as Sailor Saturn, she will destroy the world. Then, Hotaru disappears and reappears in her house seconds before Kaorinite walks into her bedroom and sees her asleep.
