The preview also mentioned what Lord Beerus and Whis would be doing in "Dragon Ball Super" episode 50.
"Beerus and Whis this week: Taking note of Goku Black's ring! - Beerus and Whis notice that Goku Black's wearing a 'Time Ring'. But originally only Kaioshins were able to use it?!"
In "Dragon Ball Super" episode 49, Goku Black is angry that he is unable to locate Future Trunks as his ki is not present anywhere. Soon, he is able to connect the dots and figure out that Trunks has used the time machine to travel in the past.
We see him using his ring which he calls the Time Ring. A portal appears and he gets inside of it.
Meanwhile, in the present, Goku and Future Trunks are fighting as Goku wants to know how powerful Black Goku is. During the battle, Trunks gets into Super Saiyan 2 mode and so does Goku. Later, Goku is easily able to beat Trunks.
Towards the end, Goku Black arrives from the portal and next week we will see Son Goku taking on the Black foe from the future. Time to bring your 'A' game, Goku Black!
