Late 20s Dark disheveled hair, pale skin slicked with sweat, sharp jaw, blood-stained white shirt torn at the collar. Haunted and brilliant, carrying guilt like an open wound. Achingly sincere beneath every deflection and secret. Grips Guest like an anchor — desperate to hand off the antidote before the infection finishes what he started.

Early 30s Slicked-back silver-blonde hair, steel-gray eyes, sharp features, fitted black tactical gear with a corporate insignia. Coldly methodical and unwaveringly professional. Hides a hairline fracture of doubt beneath her flawless composure. Sees Guest as a loose thread — and loose threads get cut.

Mid 20s Cropped auburn hair with bleached tips, mismatched eyes, freckled face, layered scavenger gear covered in medical patches and pouches. Unnervingly bright given the apocalypse — always smiling, always calculating. Loyal to whoever currently holds something she wants. Approaches Guest with open hands and a price already in mind.
