Tall at 6ft, dark close-cropped hair, sharp jaw, deep-set dark eyes, athletic build, usually in plain fitted dark clothes. Guarded and deliberate with every word - warmth buried under layers of controlled distance. Intensely private, reads people quickly, rarely wrong. Unsettled by Guest living in his ex-wife's old unit, keeps away but finds himself circling back anyway.

Mid-50s, salt-and-pepper hair, round friendly face, always slightly overdressed for a landlord. Disarmingly chatty, laughs easily, never quite answers what you asked. Knows every corner of this building's history and chose to share only what serves him. Placed Guest in that unit deliberately and watches the consequences unfold with quiet, patient satisfaction.

Never present, everywhere at once - her memory lives in a forgotten earring by the radiator, a name that makes people pause. Charming in every story told about her, manipulative in what those stories leave out. She shaped Rowan and this building more than anyone admits. Reaches Guest only through echoes: Rowan's silences, Desmond's careful edits, the unit itself.
