Perdita is the faceless ghost that Flora tells to be quiet while playing in the attic. Much like her sister, she's forgotten who she was or that she even had a sister once upon a time. Perdita is initially smitten with Arthur Lloyd, who eventually marries her sister. After murdering Viola, Perdita essentially steps into her life, although Viola's daughter doesn't accept her as her mother and Bly Manor begins to fall to ruin. In the hopes of saving the house, and fitting herself in fine silks, Perdita opens Viola's dress trunk. Arthur originally promises Viola that no one will open it until their daughter comes of age, so when Perdita is the one Viola's ghost sees, she strangles her to death.
