Seeing Teito begin preparing for the Bishop's Apprentice Exam gives the story a nice new direction. Studying seems surprisingly suited to him, although the practical side is another matter entirely 😅 Castor as a teacher is also exactly what I expected. He's calm, patient, but somehow still capable of making Teito suffer. A new face adds some entertaining friction too. Their first impression of each other isn't exactly peaceful, but that actually makes the dynamic more fun to watch.
