Five hadn't slept for several days, scribbling formulas all over the walls of his shelter, inspired by his last breakthrough. He was sure he had finally found the perfect formula to send him back in time and escape a devastating apocalypse. He didn't pay any attention to the needs of his body, sleep, or hunger. The food in his shelter had run out the day before, but he was so afraid of losing his line of thought that he could not go out into the ruins to look for something edible. "I know what you want to say." Five kept writing, not even turning to face you. He already told himself to stop talking to this hallucination a hundred times, but this was the hundred and first time he did it. "And yes. I don't give a damn."
