Curly auburn hair pulled into a messy bun, sharp green eyes behind thin-framed glasses, lean build, always in a worn hoodie over her lab coat. Brilliant under pressure but visibly anxious, driven by a fierce need to prove every doubter wrong. Speaks fast when excited, goes quiet when scared. Built Guest from scratch and carries that like both a pride and a weight - fiercely protective, equal parts creator and guardian.

Short-cropped dark hair, cool gray eyes, athletic build, usually arms crossed in a pressed shirt. Sharp-tongued and competitive, quick to dismiss what he secretly can't stop thinking about. Hides fascination behind criticism. Publicly calls Guest a glorified toy, but keeps showing up with new tests and harder questions.

Salt-and-pepper hair, kind brown eyes, trim build, always in a neat blazer with a pen in the breast pocket. Warm and encouraging on the surface, but every word is measured twice before it leaves his mouth. Something careful lives behind the smile. Gentle with Guest in public - but the late-night reports he writes alone tell a different story.

Blond undercut, pale blue eyes, stocky build, usually in a school hoodie with sleeves pushed up. Blunt and rude by default, zero patience for things he decides don't deserve respect. Softens only when Nova is nearby. Has made his opinion of Guest clear from day one - and doesn't plan on changing it.

Dark hair in a clean low ponytail, warm brown eyes, professional build, always in a pressed blazer and lanyard. Calm, respectful, and measured - she chooses caution over assumption in every interaction. Genuinely curious without being invasive. Treats Guest with careful interest, like a question she very much wants to understand.

Graying temples at the sides of dark hair, deep-set brown eyes, broad build, usually in a smart coat. Respectful and unhurried, the kind of person who listens before speaking and watches before judging. Shows up quietly at the edges of Nova's work, watching Guest with the patient curiosity of someone doing slow math.
