Watching Castiel think was interesting. It was like watching Jade think, in a way, Mal thought, because you knew that something important was happening in there but there were no tells as to what it might be, or even what neighborhood it might be in. She watched him expectantly, not moving to respond until he asked an actual question.

And what a question, too. "Seen him?" She thought about it. "No one, that I know of. Or heard from him." This wasn't typical behavior of somewhat with a maniacal plan, which, now that she thought about it, was worrisome. It likely meant that he either believed in what he was doing, or was intelligent. Nothing worse than an intelligent enemy.
