"Heartless, as weird as is it, are still... sort of hearts? It's like." Sora pauses here because the metaphysics of Kingdom Hearts make as little sense to say out loud as they actually are, sometimes. This one particular point has never made much sense even to him. "When a Heartless eats a heart, it's not like the heart just, uh, disappears. It's more like... the stuff inside? The light and the dark? Spill out and get lost. Kind of like an icecube in really, really hot water - like, sure, at the end of the day, the ice cube's water is somewhere in that water, but you wouldn't be able to make that exact ice cube ever again unless you're really lucky or knew what you were doing."

"What they did was different, though." Sora nibbles a little. Man, they do tend to talk about metaphysics over food a lot. "They wanted to exist without their hearts - without the light and the dark, and the feelings and, like, what makes people strong. Like, if we went back to the ice cube thing again, they wanted to just be the tray. People are more than just hearts, right? They've got bodies and souls too. That's the part the scientists were going for."
