In a strange way, that sort of answered Crane's previous question...if he was supposed to know Lust, then it had to have been a person. At least, if only because he honestly had no clue what else it could be. A delusion of some sort, yes, but personifying a feeling? Acting as though it could just get up and leave? It wasn't something he'd come across before. But what kind of person would have the name Lust? And why would the man think he knew this person?

"No, I'm afraid I don't," Crane replied slowly. "I'll help you find them, but first I'll need to know about them."
