"I know," he said quietly, patting my shoulder. "Because of the two percent avian DNA."
"Uh, yeah?" I mean, it was obvious that I wasn't entirely human because of the glaring pair of wings on my back, but how did he know the actual percentage?
"It's okay," he said, still speaking softly. "This is modified plasma and fluid. It won't cause a negative immune reaction. But you had just about bled out."
