[Gohan stays quiet and listens. He knows how this story ends: with his death. But it's true, he doesn't know how it got to that point. And once there's a pause, he finds himself chiming in, as if he understands where this is going. It's not hard for him to figure out what happened next.]

So then you knocked him out and went to fight the Androids yourself, right? [He feels like that's the sort of thing he'd do in that sort of situation himself, after all, so he assumes his future self would do the same. That's the kind of example they were given to live by, after all.] You wanted to protect Trunks, so that he'd be ready one day to bear everyone's hopes for a brighter future.
