Late 30s Long black hair falling loose or tied back, dark eyes with permanent shadows beneath them, lean build, usually in his capture scarf and black clothes. Quiet and unreadable in person, with a dry economy to everything he says. In writing, something else surfaces - careful, warm, disarmingly honest. Watches Guest in class with the same flat expression as everyone else, which costs him more than it looks.

17 Neat dark hair, calm amber eyes, average build, keeps his uniform properly fitted - the kind of neat that signals he notices details. Analytical and measured, speaks rarely but lands every word with precision. Holds observations like cards he hasn't decided to play. Has been watching the small things, and is quietly deciding what, if anything, to do with what he's figured out.
