When Sebastian suggested to Efthalia that he needed to inspect all the consort ladies about the unfamiliar presence of magic, Efthalia decided to have dinner with the consorts so he could do his job. He had to break the law as much as he wasn't pleased.
In the end, Sebastian was able to detect unfamiliar magic including black magic. Among all, almost 10 of them fell into the suspect list and 3 of them were already removed. Lucien was one of them.
Sebastian was as well able to find out about Lucien and why Efthalia was unable to listen to her thoughts. She had been using a charm stone to penetrate any kind of magic thrown upon her. It surprised them when they found out that Lucien had a large amount of stronger mana on her.
"Have another meal with the consort, Your Majesty," Sebastian suggested again. "I'll try to find where Lady Lucien is laying her charm. I couldn't simply go and ask or inspect her." And so, he agreed. However, the meal turned out a little disastrous.
