The silence on the matter of other people's cultures and worlds isn't interrupted. Hearts were a weighty matter as far as he's concerned, and that deserved as much musing as wondering what, precisely, changed in the passage of time.

Trauma is a terrible thing. The loss of so much, none of which he could understand save the clawing horror of his own actions in the future, that would result in the Final Days for so many other worlds...

"..As I understand it, cataclysms don't really give a lot of time to sit around exploring alternatives." Whatever God resulted, it had worked, hadn't it? And then something went wrong.. "..I wonder if in the process of all of this, your heart too was damaged, as mine is. Hearts are also the seat of memory. With them, emotions. Damage a heart and damage the memories, cripple the emotions.. but hearts too can heal, it seems. In time. With enough encouragement. I haven't observed it yet but I am told it is where my research heads eventually." As a tangent, at any rate, what happens to Nobodies was never part of the goal.. "Your heart, the hearts of those broken and dimmed.. they can heal, and become whole once more. I'm sure if I asked, I could have the research papers I'm certain to have written on it delivered to me, time troubles notwithstanding. Maybe salvation is still possible for all of us.. and we're just going about it in the wrong way right now."

Which in fact they are, but Kingdom Hearts' methods don't really apply to the Source. "I don't.. know as yet what can be done to encourage a heart to regenerate, reforge its chains of memory, and restore itself to wholeness. I can find out."

Either through outright asking, or the power of Science.
