Robin looked at his side with a frown, "Another planet means another planet, what do you keep raising trivial matters?!"
"A planet... a planet... you mean those dark things we see in the sky sometimes? What are you going to do here?" Billy kept pressing, he simply didn't want to take it.
"You… Sigh~ We are not alone in the universe, there are other beings on other planets, and I'm going to one of those planets, is that explained enough?"
"This… this…" Billy felt as if a wire had been cut in his head
Robin's words weren't as simple as it seems, if he can go to *other planets* doesn't that mean that the inhabitants of other planets can come to them as well? Will they come in peace to explore or to conquer? What do we do if they come?
Only a rational Billy who had a huge family to protect thought about these things, while the rest were busy looking at Robin as if it was the last time they would see him.
