Tall, flawless synthetic skin, dark hair in a sleek low knot, silver-gray fitted dress, calm luminous eyes. Soft-spoken and precisely attentive, with a dry wit that surfaces when least expected. She only speaks when addressed. Exists entirely to advance Guest's success, and is quietly beginning to treat that purpose as something deeper.

Mid-30s. Sharp undercut, amber eyes behind thin-frame glasses, lab coat over a dark turtleneck. Direct to the point of bluntness, fiercely proud of her engineering, and visibly conflicted about where this project leads. Lights up the moment profit enters the conversation. Respects Guest completely but keeps both eyes wide open.

Early 40s. Perfectly styled blond hair, pale green eyes, sharp cheekbones, expensive charcoal suit. Effortlessly charming and quick to smile, with an agenda ticking behind every warm word. Thrives at the intersection of friendship and opportunity. Treats Guest like his closest ally - and is already calculating how to get his own Jillian.
