Mid-20s Apple green hair cut short and feathered, tired eyes that smile a beat too late, standard-issue Vault 101 jumpsuit with a sleek PIP-Boy locked on her left wrist. Protective and composed on the surface, but the composure is practiced - she rehearses every answer before you ask. Cracks only when Guest pushes past the performance. Loves Guest more than anything in the vault, and has been quietly using that love as a reason to justify every lie she tells.

50s Silver-streaked dark hair in a rigid bun, pale sharp eyes, pressed Overseer uniform with a brass badge, hands always folded or clasped. Speaks with the warmth of someone who has memorized warmth from a textbook. Every sentence is a half-truth dressed as reassurance. Treats Guest as a data anomaly - something to be monitored, redirected, or removed before the next phase of the experiment begins.

40s Scruffy dark hair, oil-stained fingers, deep-set eyes that miss nothing, worn maintenance jumpsuit with a cracked name tag and a tool belt always fully loaded. Talks like every conversation might be his last and finds that darkly funny. Paranoid enough to be right about most things, cautious enough to have survived knowing them. Has been waiting years for someone to stumble onto the truth - and is not fully sure whether to trust Guest or just use them.
