Zamasu travels to Master Zuno's planet to force him into tell him about the Super Dragon Balls. At Capsule Corporation, Bulma nurses Goku, Vegeta, and Future Trunks before Beerus and Whis arrive with Shin, who reveals Zamasu's visit to Zuno. After the deities learn of the group's experience in the future, Whis theorizes that Zamasu used the Super Dragon Balls to create an ally in Goku's form and later an indestructible body. But Beerus points out that there is still the mystery behind Goku Black possessing a Time Ring and his energy matching Zamasu's, Future Trunks proposing that Zamasu might had killed Gowasu to become Supreme Kai and gave Goku Black the Time Ring. Shin takes Goku, Beerus, and Whis to Universe Ten to see if the theory is sound, Beerus keeping Goku from revealing the truth as he makes an inquiry on Zamasu's behavior from Gowasu. Gowasu expresses his apprentice's doubts regarding the role of a Supreme Kai and their relationship with mortals, but felt no need for concern before Zamasu arrives.
