What would happen if Grand Supreme Kai met Supreme Kai?

[DBFanTalk]

The Galactic Patrol Prisoner arc reintroduced the character of Grand Supreme Kai as a rival to the villain Moro. The arc is currently ongoing and in it's third-act however, the character of Supreme Kai (and Old Kai) have been absent completely. We have yet to see a reunion between master and pupil. How do you imagine this event unfolding?

Dai Kaioshin: Huh? Where are the other Kaioshins? None of them were reborn?

Kaioshin of East: Yeah, I've been almost alone this entire time. Having to watch over the entire Universe all by myself, a job that requires four of us. By the way, I've also been slacking in creating planets and life, thug life, bro.

Dai Kaioshin: There's something really wrong going on behind the curtains...

I think he'd be embarrassed to learn of how low Universe 7 has fallen since his disappearance. He'd be like:

"I devoted my entire life to the stability and prosperity of U7, and you mean to tell me that our universe has the second lowest mortal level in the cosmos? What the hell happened after I died???"

he was described as generally being a happy-go-lucky person, who even forgot to teach Shin a lot of stuff so...

maybe there are no new Mohawk golden fruit after the Buu invasion that why other direction Supreme kai position are left vacant.

Maybe. I'd like a confirmation on that, but I doubt they'll ever provide one. There is this interview which Toriyama comments about their birth but not much clarification is provided. The Kaioshin Realm still exists so there should still be a way for them to be born. Then again, everything he said in that little paragraph is contradicted by the series, since no Kaioshin "grew like a planet" since they were killed.

I was wondering the same thing myself not so long ago.
I imagine he would treat the old Kaioshin with a lot of respect because he still is many generations older than the Dai Kaioshin, but would be much more in control of everything than Shin. He'd treat Shin as his little brother, I guess. He'd congratulate him for keeping the universe alive, or at least for seeking the right help to do so. He seems like the glass half full kind of people.

What I'm more interested about is how would Beerus and the Dai Kaioshin get along...

I think his competence would impress Beerus.
He'd probably say he was a fool to give away his power leaving him to get killed but secretly he'd be impressed, he'd probably want him to stick around and would rather have his life link be on him.
