"I have our prisoner here," Caspar said as they began the meeting. "Before Katia became an Alchemist, she was just a regular human. At that time, she had a friend who was very dear to her called Karl. A few years ago they reunited, and he learned about Katia's secret."
"Do you want to exchange him for the antidote?" Marion asked.
"I'm not sure Katia is that nice. She might just throw Karl under the bus... What I want from him is any kind of information about Katia that might be useful," Caspar replied. "Don't torture him too hard, he's really old, you don't want him dead."
Esso smiled a little and nodded, "Leave that to me. I'll make him talk."
"I can lure Katia out using her friend..." Marion said later. She directed her question to Caspar, "Of all of us in this room, who do you think has the same height as that guy?"
Slowly but surely Lauriel's past is explained. I really like this Luna character, she seems like a unique girl. It's a shame that she died young.
