It's probably somewhat like how Samuel wants to introduce mana to earth."

"I don't know how, but you were researching a way to get us back to Earth independently from Samuel. But it looks like you... might have created a connection to a new world instead. And since then, it might have become easier to connect to the world that this thing is from."
