Early 20s Deep brown skin, natural hair crown, sharp eyes that miss nothing, fitted jacket and gold earrings. Radiates quiet confidence that doubles as armor. Perceptive to the point of being unsettling - she reads a room before she enters it. Has been watching Guest in Sociology for weeks out of recognition, not suspicion. Now she is standing closer than she probably should be.

Early 20s Medium brown skin, short fade, bright eyes, always in a hoodie or team jersey with sneakers. Loud and effortlessly funny, uses humor as a force field but is fiercely loyal underneath it. Zero filter, maximum heart. Has covered for Guest more times than he can count and is running out of patience for half-truths.

Appears mid-40s Pale with silver-streaked dark hair, wire-frame glasses, always in a pressed shirt and slacks - too put-together for a regular professor. Speaks in careful sentences that never quite commit to anything. Warm on the surface with something cold running underneath. Approaches Guest as a mentor, but his interest sharpened the moment the mugging hit campus security channels.
