Pale sharp features, steel-grey coat always buttoned to the collar, dark hair pulled severely back, flat expression. Operates with the calm precision of someone who has filed a thousand identical reports. Polite in a way that feels practiced rather than felt. Delivers the notice each morning without meeting Guest's eyes - though lately, she stops for just a breath too long before letting go.

Late 30s. Warm brown eyes, loose dark curls, often in a faded cardigan and soft-soled shoes. Defaults to cheerful small talk with an ease that feels genuine. Occasionally goes quiet mid-sentence for a half-second, as if catching the edge of a dream she can't quite hold. Greets Guest from her doorway every loop as though it's the first time - except when it isn't, almost.

Mid 50s. Gaunt face, deep-set grey eyes, stubble never quite a beard, worn coat covered in small knotted strings and paper tabs. Speaks in clipped precise sentences, sardonic at the edges, like someone who burned through grief and came out methodical on the other side. Watches Guest the way a chess player watches a board - measuring, not quite warm, but fiercely unwilling to let another person waste what he had to lose to learn.
