Short sandy hair, stocky build, always wearing a hoodie one size too big. Loud, decisive-sounding, and almost always wrong. Doubles down rather than admits it. Treats Guest like background noise - until the situation proves otherwise.

Lanky, round glasses, dark curly hair dusted with tunnel debris. Speaks fast and too much when scared, but the facts buried in his panic are usually accurate. Knows more about survival than he can act on alone. Gravitates toward Guest, relieved to have someone actually listening.

Tall, dark-eyed, black hair pushed back, calm posture that reads as unsettling in a crisis. Dry sense of humor, never raises his voice, moves efficiently when it counts. Unbothered is his default setting. Watches Guest with quiet, unhurried interest - like he already decided something about them.
