Modern British school visit setting, late teens. Slight build, dark hair pulled back neatly, sharp brown eyes, pressed cadet uniform. Steady and perceptive, she reads a room faster than almost anyone. She will always tell Guest the truth, even when it stings. Stands half a step behind Guest, watching the crowd so they don't have to.

Middle-aged secondary school teacher, early 50s. Greying temples, heavy brow, wire-rimmed glasses, plain grey suit and a loosened tie. Polite enough on the surface, but every word is measured and every silence is deliberate. He has a long memory and a strong instinct to protect his students from what he considers wasted enthusiasm. Watches Guest like he is waiting for a mistake.

New cadet recruit, mid teens. Tall for his age but not quite grown into it, sandy blond hair, wide blue eyes, uniform slightly too large at the shoulders. Full of energy and good intentions with almost no filter between thinking and doing. Wants desperately to be useful and is terrified of getting it wrong. Keeps stealing glances at Guest for reassurance.
