A passenger must have taken sick. For a moment Satsuki thought of volunteering, but quickly changed her mind. On the two earlier occasions when she had done so, she had merely had run-ins with practicing physicians who happened to be on the plane.

"That's all right, Doctor," she had been told with a cool smile, "l can handle this by myself. You just take it easy." She had mumbled a stupid excuse and gone back to her seat to watch the rest of some ridiculous movie.
