Zamasu and Black - The Mystery of the Two Deepens. Wanting to learn more about the Super Dragon Balls, Zamasu visits Zunō-sama's planet. Under duress, Zunō-sama explains exactly how the Super Dragon Balls work and where they are. At Capsule Corporation, Bulma nurses Goku, Vegeta, and Future Trunks back to health. Beerus and Whis arrive with Supreme Kai. After listening to what happened in the alternate timeline, Whis posits a theory as to what exactly Zamasu is planning. He believes that, after losing to Goku, Zamasu became obsessed with Goku and his incredible power. Zamasu needed an ally as powerful as Goku to achieve his goal of obliterating mortals. Goku Black was therefore supposed to be a copy of Goku and created using the Super Dragon Balls. Whis also adds his earlier theory about how Goku Black is able to time travel using Supreme Kai's method. He believes that their timeline's Zamasu is the one who is going to kill Gowasu and give Goku Black the time-traveling device known as the Time Ring (時の指輪 Toki no yubiwa). Supreme Kai takes Goku, Beerus, and Whis to Universe Ten to warn Gowasu, while Vegeta stays behind. They arrive to the Supreme Kai Realm (界王神界 Kaiōshin Kai), where they meet Gowasu. Gowasu explains that Zamasu has left on what he called an important mission. Goku tries to warn Gowasu of what Zamasu has done in the future, but Beerus promptly silences him. They wonder if Gowasu noticed anything wrong with his apprentice. Gowasu mentions the doubts Zamasu has had regarding the role of the Supreme Kai and their relationship with mortals, but it should not be a cause for concern. Just as Gowasu finishes, Zamasu arrives.
