Haneul does not like the implications of that. "People wouldn't be able to die, would they? Or... their souls wouldn't be able to pass on properly, maybe? I don't know how that really works for you."

God, this whole conversation is incredibly surreal, and he really wishes Josie were here because he'd probably be better at not asking the exact kinds of questions that would freak himself out, like Haneul is doing right now. And then he feels bad, because why should he wish Josie was stuck here?
