It's answer enough for Sebastian, since really, any further explanation likely wouldn't help him understand any further. It's also an answer that makes him laugh, since even in its simplicity, it feels both perfectly fitting and deeply ironic.

"How unexpected," he comments with the laugh still in his voice, "I have never met a priest whose god actually deigned to listen."

And in that, there's much he wants to tease at too. There's a special pleasure in taunting faith, because his very existence is opposed to it. He's met people who claimed to wield "light" before, and he had very much enjoyed watching their belief fade as it proved impotent against a very real force of the devil. However, tempting as it was, he wasn't quite so foolish as to play with fire in this case.

"You would certainly be glad for it as well. My home was that where wickedness came. A darkness to the light, naturally."
