[ "I am sure that those of us humans in your world are especially grateful to you." 9S's mouth tightens there with a thought not worth voicing. Ophilia's sentiment isn't lost on him, though; it's just another example of that singular kindness that humanity possesses. He can't manage to school his expression into something lighter -- he keeps looking out into the night to keep from directing it at her -- but his voice at least is carefully gentle. ]

I don't know if I'm anything as grand as a guardian spirit. [ He gestures widely at his candelabra-turned-spear, and at his self-appointed guard posting. ] None of this is what I was made for. And I'm hardly infallible myself.

But... [ A complicated emotion grips his voice. He can't say if it's his programming or his own willful desire; perhaps they're inseparable. ] I promise to fight for humanity with all my strength. As meager as I am, I'll do all I can to live up to your expectations.

[ He finally turns his head to look at her. ]

Thank you, ma'am.
