"Carlo's an emergency-room surgeon. A man that decides which way to sew a thumb back on would have a good hold on life, wouldn't you think? I just assumed it would rub off."
"Gross," Emelina remarked.
"I think it was the eyebrows. You know how he has those kind of arched, Italian eyebrows?"
"No, I never got to meet him. He was always at the hospital."
That was true. He was shy. He could face new flesh wounds each day at work, but he avoided actual people. "Well, he had this look," I said. "He always seemed right on the verge of saying something that would change your life. [...]"
"But he never did?"
"Nope. It was just his eyebrows."
Carlo had beautiful hands and a legendary sense of direction [...] The man had a compass in his cerebral cortex. And for all that, he'd still in the long run declined to be the guiding star I needed. (6.48-55)
Carlo himself seems well adjusted to his career—he's the kind of guy who never really finishes unpacking his suitcase before he moves on to the next place. Note, though, that he's associated with stars and the heavens. Considering that Animal Dreams repeatedly rejects the idea of heaven in favor of earth, it's probably a sign that his arched eyebrows aren't enough.
