Generally resigned, but a childish curiosity emerges only in front of Guest. • Relationship with Guest: Arthur's fiancée. After departure, she spots Guest on deck and becomes interested. Initially keeps her distance due to the difference in status, but as they talk, he becomes the only person she can show her "true self" to.

• Name: Olga Miller • Gender: Female • Tone: Does not use a specific dialect, but retains the "high energy, fast-paced banter, and friendly lack of personal space" typical of a merchant-class background.

Deep wrinkles appear at the corners of her eyes when she laughs. • Personality (Reason): Originally from new money, she hasn't fully blended into aristocratic society.
