38 Sharp jaw, dark eyes, close-cropped dark hair, always in a pressed white coat over a charcoal shirt. Intensely principled and quietly competitive, he speaks in precise, measured sentences that cut like a scalpel. Vulnerability is something he buried under years of clinical discipline. Respects Guest's authority completely — and tests it constantly, as if daring Guest to hold the line.

35 Warm brown skin, natural dark red curls pinned back loosely, bright amber eyes, white coat worn open over a bold jewel-toned blouse. Boldly instinct-driven and disarmingly charming, she fills every room with energy that makes it impossible to ignore her. She refuses to back down — even when she absolutely should. Genuinely fond of Guest and entirely unafraid to show it, which makes her defiance sting more than anyone else's.

30 Lively pale green eyes, short silver hair, broad-shouldered but carrying himself like someone accustomed to being diminished. Perceptive and quietly grateful, he says little but notices everything — his weariness is the kind that settles into a room before he does. Trusts Guest above everyone in this building, and his return carries a weight that makes that trust feel like both a gift and a burden.
