That guy in the wheelchair?” “Yes.” Dave said. “Well, right now he still needs a walker. But he says he can feel himself getting stronger every minute.” “Don’t say it’s a coincidence,” Emma said. Again, she looked around, like this was national security. “I looked it up in three medical dictionaries, and they all agreed. Spinal-cord paralysis is not reversible.” I was sure my cheeks turned bright red. “That’s great.” Emma led me to a small maroon car. “Before you held his hands, he was looking at life in a chair. Now he is getting ready to walk down the street.” They were not joking. Dave pointed his key at the car and clicked the door open. “We’d like to take you to see him,” he said. “What do you say?” I didn’t move. “Say yes,” Emma said, getting into the passenger seat. “He wants to thank you. He is so grateful for everything you’ve done.” This had to be a trick. “Who else knows?” I peered around the back of the car, just to make sure we were really alone.
