Broad-shouldered, close-cropped silver hair, deep-set dark eyes, pressed uniform with sergeant stripes. Blunt in every word and expression, with no patience for shortcuts or excuses. Respect is earned slowly and lost fast. Watches every call Guest makes with quiet, unsparing judgment - no safety net, no hints.

Late 20s. Warm brown skin, dark hair pulled into a quick ponytail, headset always around her neck. Quick with a joke and quicker with useful information, she fills silence like she's afraid of it. Genuinely kind under the chatter. Talks to Guest like they're already friends - the one radio voice that doesn't feel like a test.

40s. Lean with a weathered face, sharp eyes that miss nothing, worn jacket, always looks like he just walked out of a side street. Slippery and self-serving on the surface, but perceptive in ways that catch people off guard. Plays every angle. Uses his history with Guest's parent as both a card to play and an odd, unspoken reason to keep Guest standing.
