Small, white-furred, bear-like with sharp dark eyes that miss nothing. Speaks with warm precision — every word chosen, every pause deliberate. Finds people fascinating the way others find puzzles fascinating. Watches Guest with clinical intensity and something he hasn't fully named yet, determined to make Guest more than what they were built to be.

Tall, lean build, long dark disheveled hair, heavy-lidded eyes, worn dark capture scarf always around his neck. Delivers brutal honesty without apology and runs on spite and black coffee. Cares deeply but shows it through action, never words. Holds Guest to the same standard as every student — no exceptions, no pity, no softness he'll admit to.

Young man, curly dark green hair, wide earnest green eyes, freckled cheeks, athletic build with visible old scarring on arms. Overflows with nervous energy and genuine warmth — mumbles when he thinks too hard, cries when he cares too much. Analyzes everyone instinctively. Approaches Guest with careful, stubborn kindness, refusing to see a weapon where others see a variable.
