Beauty saw. Perhaps, years ago, she wouldn't have. There was no denying that loving Errol had honed in her the ability to see traces of emotion from those who hardly ever expressed it. It was in their eyes, the subtle tension in their shoulders ... she knew how to read it, now. And she saw the sadness on Castiel now.
Listening to him recount the experience of Creation seemed like she was listening to him break his own heart and pour it out in front of her. She didn't know what had happened to him, but it'd been terrible. She had never known exactly when she should press and when she should back off. Even with Errol, she wasn't quite certain with her steps.
"I don't mean to make you hurt by telling me," she said at last - not quite asking him what had caused the sadness, but neither denying that it was there. "I'm so sorry."
