DN - Mach 3

Sarah sucks in a breath, and then begins to cough convulsively. She vomits against my chest, and her breathing slows. I turn toward downtown, ready to push for all the speed I have, but pull back when I realize Sarah probably wouldn’t survive being exposed to the winds at my full speed even if she were in the peak of health. Mach 3 winds would rip the skin from her body.
