A young, nervous-looking substitute named Ben fumbled with the tourniquet. “Okay, Leo, let’s see what we’ve got,” Ben said, patting Leo’s forearm. He looked at the pale, scarred landscape of Leo’s inner elbow. He sighed. He palpated gently. He sighed again.

Leo’s infusion pump beeped, a cheerful little chirp that meant the bag was nearly empty. For the hundredth time that day, he glanced at the clear tube snaking into his arm.
