[spoiler]The human was silent. No begging, no pleading for life. At the end, acceptance came even to this strong, turbulent spirit. "You said I could ask one more question."

"I can't ask if we win, I can't ask if it will all turn out okay."
"I don't know those answers."
"Okay, then answer this, Ellimist: Did I… did I make a difference? My life, and my . . . my death . . . was I worth it? Did my life really matter?"
"Yes. You were brave. You were strong. You were good. You mattered."
"Yeah. Okay, then. Okay, then."
