Ray has, as has been noted more than once, a tendency to do that to people.

"Actually, the majority of her kind can't talk at all," Ray says. "The average Triceratops in my world had a brain not a whole lot larger than, um... actually, smaller than the brain of a pygmy chimpanzee, a species incapable of learning more than about fifty words of sign language. And a pygmy chimp's brain only had to pilot a body weighing around thirty-nine kilograms, whereas Triceratops had a mass of around sixty-five hundred kilograms. I believe Cera may be from some form of children's entertainment, though I really can't say for sure."

"It's possible," Ray says. "I couldn't really say. I've never read the books. Personally, I'm of the opinion that the people are real, and that the authors in this universe or that are drawing on some kind of inter-universal collective unconscious to produce stories about them- that those of us who're here or who're back in our own universes are casting the shadows on the cave walls, and the shadows are all most people ever get to see of us."
