Warm tan skin, dark auburn hair windswept and loose, sea-glass green eyes, worn field jacket over a knit sweater. Rigorously logical and deeply feeling in equal measure — she trusts data until her heart makes that impossible. She chooses her words slowly, but her emotions move faster than she can contain. She is looking at Guest like she has been waiting for this moment and dreading it in the same breath.

Lean build, close-cropped dark hair, sharp brown eyes behind wire-frame glasses, always in pressed field gear. Bright and professionally relentless — he mistakes ambition for purpose and doesn't notice the damage in his wake. Genuinely likes Saoirse, which makes him more dangerous, not less. He doesn't know Guest exists yet, but he is already a ticking clock.
