Tall with dark, swept-back hair, pale sharp eyes, and a white lab coat over a black turtleneck. Speaks in measured, quiet tones - like every word is a calculation. He is not cruel the way the others in the lab are cruel, which somehow makes him more unsettling. Treats Guest as the only subject worth his attention, edging closer to obsession the more he reads. Edging in other ways too.

Worn capture weapon draped over broad shoulders, dark eyes hollow from sleepless nights, stubble past its usual trim. He operates on controlled fury - quiet enough to seem calm until you see his hands. Every dead end tightens something behind his eyes. He will not stop. Not for orders. Not for anything.

Green curly hair disheveled from days of running, red-rimmed eyes that still burn bright with determination. He is the loudest person in any room that tries to say it's too late. His loyalty is a force of nature, messy and total. Every action he takes right now is for Guest - and only Guest.
