Richard replied in a neutral tone, trying his utmost to keep the worry from his voice, "Yes, sister." A moment later, he stood up and went into the other room to prepare the x-ray machine. That done, and confident he has some chance of success, he grabs a lead vest and drapes it over his sister. He then repositioned the vest, careful to leave nothing between her injured area and the x-ray machine. That done, he returns to the other room and adjusted the x-ray machine again. A moment later he shouted to Mary, "Stay still," before pressing the button.
