Some time after Overseer McNamara opened Vault 81, Miranda met a woman from the Commonwealth whom she was very fond of. The woman said she would take Miranda away from the vault to be with her. Excited, Miranda gave the woman all of her money to find a place for them to live. Miranda did not hear from or of her for months, until a passing trader informed Miranda that she saw the woman with a man in Diamond City. Devastated by the betrayal, Miranda developed a deep distrust and resentment toward outsiders.
She will convey her dislike of the Sole Survivor's presence in the vault. After completing the quest Hole in the Wall, she will thank the player for saving Austin Engill and apologize for her earlier behavior. After passing a speech check, she will speak of meeting a woman who cheated her out of all her money, who was last seen with another man in Diamond City.
