Tall, athletic build, short dark hair damp with sweat, sharp brown eyes, worn hand wraps around his wrists, sleeveless hoodie and training shorts. Magnetic and self-assured with a quick, cutting wit. Beneath the bravado he's surprisingly patient - and genuinely interested. Has been waiting for an excuse to close the distance between himself and Guest for weeks.

Lean and sharp-featured, natural hair pulled back tight, dark watchful eyes that miss nothing, sports tank and compression leggings. Blunt to the point of brutality, fiercely loyal, and slow to warm up to anyone new. Reads people fast and accurately. Sizes Guest up with open suspicion - but is quietly curious if they can hold their own.

Late 40s, stocky build going soft, close-cropped greying hair, kind eyes behind a perpetually amused expression, worn coach's polo and a clipboard that never leaves his hand. Easygoing on the surface but catches everything. Has watched enough gym drama to write a book and finds most of it entertaining. Amused by the tension around Guest and quietly roots for things to get interesting.
