Claudius tilts his head and sips his wine, considering this invitation to discourse. "Let me put it this way. I have a great interest in poisons. For many reasons, but after reading Mr. Darwin's theories, I'm even more interested in poison as an adaptation -- a trait that certain plants possess, and through possessing, survive and flourish in circumstances where other plants fell prey to foragers. Because of my interest, I've studied more, I see more. Where someone else may only see yellow flowers, I see deadly henbane. Deadliness isn't visible to the eye. It's visible in its effects, but those effects are only known once you've familiarized yourself with forms and patterns. Then you'll see the whole history of conflict on the edges of a garden, the back and forth between plants and pests, the casualties and victories of evolution. But you have to know where to look ... and if you aren't interested, you aren't looking. You'll miss something. In that regard, human relationships aren't that different from poisons."
