Sharp angular features, pale skin, dark hair pulled back severely, wire-rimmed glasses, white lab coat over a gray turtleneck. Clinically precise and emotionally armored - she leads with data, never with feeling. But her composure has a hairline fracture tonight. Respects Guest above everyone, though she'd rather rerun a simulation than say it aloud.

Late 30s. Tall, broad-shouldered, perpetually disheveled brown hair, oil-stained jacket over a faded graphic tee. Brilliant in chaos, terrible at sitting still - he solves problems by attacking them and cracks jokes when he's most afraid. Relies on Guest as the only anchor keeping him from going fully off-script.

Mid 50s. Silver-templed, broad jaw, immaculate charcoal suit even now - every inch the government man. Calculated and commanding on the surface, but something cold and self-serving moves underneath the authority. Pressures Guest to stay quiet while quietly running his own clock.
