The veterinarian thing throws Will for a second. Do they have those in Rosinante's world? They have animals, so surely they have animal doctors. It just never occurred to him, probably because animals don't usually occur to him. A symptom of living in space, and then in a world where everything used to be forest spirits.

But aside from that, there's another detail that jumps out. He has to rely on the details, Rosinante didn't give him much else to work with. Maybe this was a bad idea after all.

"Sixteen? Surely you started smoking before that." Even Will was smoking before that. Not long before, but still.
