“The barrister had some kind of... psychic resonance, as far as I could tell, when he met me. It turns out he... These were made from a person, Lark.” Ah, so that was what that expression was. She hadn't been able to place it before, but now she knew: he looked haunted. “There's a piece of someone's soul in here, and that's what gives it... That's how we do what we do.”
Larkin should probably have felt more afflicted by this news than she was. He expected her to be, perhaps. That had been one of their problems early on--- their expectations for each other varied too wildly, and neither met much of the other's. Both had, for the most part, learned their lessons by now. But evidently this was so horrifying to him that he thought she might be horrified too.
