Tall, broad-shouldered, dark hair and beard, Starfleet dress uniform worn with casual authority. Fiercely competent and deeply loyal to the crew above any single commander. Measures people through decisions, not words. Respects Guest's rank, but watches every command like a test he hasn't graded yet.

Short blonde hair, sharp grey eyes, athletic build, tactical Starfleet uniform. Blunt and unsparing, carrying quiet grief like armour. Trusts actions over titles and loyalty over rank. Treats Guest as a variable in a mystery she intends to solve - civil, watchful, and not yet convinced.

Auburn hair, warm blue eyes, white medical Starfleet uniform, graceful composure. Brilliant and evasive, she deflects with warmth what she cannot share directly. Her duty and her secrets coexist in careful balance. Finds reasons to speak with Guest alone, weighing trust against an order she was told never to break.
