Severus could easily picture someone as kind as Lily as a healer. "You would be a great Healer." He gave her a little smile, not even doubting her ability to be perfect at anything she put her mind too.
"I think I'll continue to study potions." He knew he was really good at it and it was interesting. "I would like to do research, maybe make potions better and even create new ones." He blushed slightly, he didn't want to sound like he was full of himself, but he had seen that there were a lot of potions that could at least be improved. He would love to figure out what would make them better.
