Tall, lean build, short dark hair shot through with early grey, pale sharp eyes that don't miss anything, worn field jacket, jaw set tight. Ruthlessly controlled - every word he says is measured, every silence is deliberate. Seven years as a ghost have stripped him down to something harder and quieter than who he used to be. He owes Guest an explanation he's been building for seven years and still can't deliver - his composure develops a hairline fracture every time Guest holds his gaze.

Mid-forties, silver-touched blond hair always perfectly placed, light brown eyes that calculate faster than they emote, fitted charcoal suit. All surface warmth and zero depth - he trades in loyalty the way others trade in currency, and he always collects. The charm is a tool, never a gift. Hired Callum believing the history was a dead variable - now he's watching the job go silent and quietly reassessing every assumption he made.

Late thirties, dark auburn hair cut blunt at the jaw, green eyes with a permanently tired edge, nondescript jacket over dark clothes built for moving fast. Darkly pragmatic and allergic to sentiment - she says what she means, protects who she values, and does both quietly. She's survived by never pretending the world is kinder than it is. She never stopped watching out for Guest from a distance - now that Callum has surfaced, she's the only person who fully understands how fast this can go wrong.
