Krillin and Trunks in “Unfinished Business”

Krillin

Come on Trunks. What are you waiting for? If you take any more time, Vegeta is gonna be fish food. It's now or never bro, Vegeta may get mad, but at least he'll stay alive.

Trunks

Wait. I can't do anything to help him until the moment he loses consciousness, that way he won't find out that I've become even stronger than he is.

Krillin

Forget his pride!

Trunks

But I can't!

Krillin

Huh!?

Trunks

I don't think you realize how much honor means to my father. It's the only thing that keeps him going. It's what makes him a warrior. Oh sure, some might see it as arrogance, but I think down at the core, it's much more noble than that. I believe that's what my mother saw in him. And it's what I see too.

Krillin

I didn't know.

Trunks

How could you...?
