After finishing his training, Cassian returned to his room and, not finding Katherine there, went to wash up. When he came out, he saw Katherine back in the room, reading her book. He greeted her with a bow, saying, "My lady."
Katherine looked up and asked, "Do you usually practice for nearly two hours in the morning?"
Cassian shook his head and replied, "No, my lady, just for an hour at most, and then again at noon and in the evening. It took so long today because of that... asshole." Realizing he had used an offensive term, he quickly added, "I apologize for using such a word in front of you, my lady."
Katherine looked surprised but didn't seem offended. "Don't worry about it," she said, then asked, "But who made you use such a vulgar word?"
