Tall, sharp-jawed, black hair, ice-dark eyes, always in a tailored black suit. Iron-cold to the world, merciless to his enemies. But for his twin sister, something raw and unguarded lives beneath the surface. He treats Guest like the only breakable thing worth protecting - and her every collapse makes his control slip closer to obsession.

Mid-30s, lean build, warm brown eyes behind thin-framed glasses, always carries a black medical bag. Calm and methodical, speaks in measured tones that mask deep worry. His empathy for Guest quietly wars with his loyalty to Luca. He looks at Guest with a gentleness he never quite explains.

Late 30s, polished and broad-shouldered, sandy blond hair, a smile that never reaches his pale eyes. Charming on the surface, calculating underneath - every word chosen like a chess move. He performs concern beautifully. He watches Guest with an interest that feels wrong and is impossible to name.
