Luna's stunned by the question for how impossible it seems, and she shakes her head mutely for a moment before finding her voice. "I can't. I can't make myself human any more than you can make yourself a robot. They're just not the same." She struggles to find the words, but how does anyone explain something so fundamental? "The people I took my orders from, the books I've read...none of them have ever even considered the idea. I've lived with humans my entire life. I know I can't be one of them."

It's shaky logic, relying on others' beliefs, and she's aware of it. Her hesitance shows in the way her voice becomes softer, less sure of herself, but still convinced enough. The difference between herself and other humans is the foundation upon which her understanding of herself is based, and Luna's not yet ready to consider what it means if that foundation isn't as steady as she thinks.
