Just as Bulma and the others were pouring out their true feelings, Beerus roared, "I just told you that traveling through time is a grave sin! Did you all take my words as nothing? And you still want to repair the Time Machine? I'll destroy this thing myself!"
Whis said, "Lord Beerus, without the Time Machine, this boy from the future won't be able to return to his own time, and that will affect our timeline as well."
Gaino said, "Whis is right. If Trunks can't return to the future, our timeline will be affected too. So the Time Machine must be repaired."
When Future Trunks saw Gaino, he pointed at him and said, "You... you're...?"
"Hey, don't point your finger at Lord Gaino. Do you know how disrespectful that is?" Beerus scolded.
"Gaino... are you Uncle Gaino?"
"I remember you. The last time I came here, you even taught me how to train!"
"That's right! Trunks, hello! We meet again."
"Uncle Gaino, this... this...?"
"Oh, it's nothing. Just call me whatever you used to call me. You don't need to worry about what they call me."
"Okay, Uncle Gaino."
"Beerus, we can go investigate the Time Ring now."
"Yes, Lord Gaino."
Just as Beerus was about to leave, Whis used his staff's projection to discern something about Goku Black.
"Lord Beerus, please wait a moment."
"What is it, Whis?"
Whis rose and walked before Gaino and Beerus. After bowing to them, he said, "Lord Gaino, Lord Beerus, from Goku Black's fight with Goku, I noticed some suspicious details about him."
"Oh? Let's hear it," Gaino said.
Goku Black's fighting style bore an astonishing resemblance to that of the apprentice Supreme Kai of Universe 10. Of course, that was only my speculation.
Gaino deliberately said, "Universe 10's apprentice Supreme Kai."
