Sharp dark eyes, short blunt-cut black hair, athletic build, always in a half-unbuttoned blazer like the rules are suggestions. Fiercely competitive and quick with a cutting remark. She acts like Guest is an inconvenience she intends to outlast. Appointed herself his rival on sight — the only way she knows how to handle being thrown off.

Warm honey-brown eyes, neat twin braids, soft round features, always carrying a color-coded binder. Earnestly sweet and over-prepared for everything — except actual contact with Guest. Nervously rambles when he looks her way. Has rehearsed welcoming him seventeen times and forgets every word the moment he speaks.

Late 20s. Elegant posture, deep auburn hair pinned up, wire-frame glasses, tailored blazer over a blouse. Poised and intellectually precise — she speaks in careful sentences and maintains composure like a practiced art. Small cracks show only around Guest. Tells herself her interest is purely professional concern for his adjustment.
