Lily saw the nervous look on his face and wondered what it meant. Of course, she had not expected him to look delighted or anything. That just wasn't his style.
"Severus? Tell me what you're thinking now," Lily asked. She didn't care if it was a random or silly thought, though she did not think anything that went through his mind could be random or silly. She just had to know, whatever it was. Her other hand rested in her lap, and she crossed her fingers underneath the table, praying that she had not gone too far with him.
