To be honest, ever since Gran became a Candidate God of Destruction, he had mostly watched affairs in the Mortal Realm as if they were a show.
Trunks's situation was one of the few things that interested him.
As with that other Future Timeline, he didn't want to see such a tragedy happen, so he had stepped in.
But Universes 6 and 7 were both preparing for the Inter-Universal Martial Arts Tournament, and he had to keep an eye on them throughout.
Besides, he had promised Kronoa that he would help her deal with Mechikkapula when the time came.
Then there was his own training... In short, he had a mountain of things to deal with.
Of course, the main reason was that Gran couldn't be bothered!
The Trunks before him wasn't like the one he had met before. He probably wouldn't ever see that Trunks again.
This Trunks, however, would have a great deal to do with Gran's timeline. There would be plenty of chances to meet him again.
And if all else failed...
When Zamas appeared, Gran could simply go over and destroy him.
"But Lord Gran, you clearly said before..."
Bulma sounded anxious.
"Mom... Aunt Bulma, it's fine. There's no need to trouble Lord Gran." Trunks's heart had leaped into his throat when he heard Bulma's tone.
Could she really speak to a Deity like that without getting killed?
The other Z Fighters had long since grown used to it. Only Bulma dared act so freely in front of Lord Gran.
"Bulma, has something gone wrong with your head lately?"
Gran pressed a finger to Bulma's temple and gave it a tap. "There are so many strong fighters here you could ask to teach him, yet you want me, a Candidate God of Destruction, to do it?
