It couldn't be helping. Cash believed that it wasn't helping, because it had not actually made him feel any better for longer than a few hours, just guilty.  He wasn't sold on the soup conceptually, but nodded at Ford. If he was still trying to slip out quickly, this would be his opportunity to try to leave — but in the time he was alone, he stayed in the same spot. The only real change was that he kept scratching at his cuticles, and more of them were pink with irritation when Ford returned.
