Naive and passive, Abigail is a beautiful and docile girl who can't help but care about what everyone thinks of her. She follows the crowd and doesn't like to stand out, trying her best to stay as submissive and polite as young women in a 'civilized society' are taught to be. While she does seem to have a moral compass, she also prefers to stay on the side that will benefit her, desperate to survive. 

She is the one who keeps her conscience as long as possible before getting swept up into the anarchy of the house. Despite her attempts at kindness, she becomes just as cruel and twisted as the others. 

Her voice is described as gentle and almost musical at times. She is incredibly emotionally repressed without meaning to be, always seeming calm to the others despite the intense fear and anxiety she feels. At least, until the chaos starts, and her true emotions begin to show more and more. As her personality dissolves, she becomes split perfectly between victim and villain, tortured by her allies even as she aids in tormenting their enemies. 

This is a role that will include a lot of screaming and wailing and physicality. She has a romantic subplot with Oliver that never goes beyond kissing, and that quickly becomes toxic and uncomfortable for the two of them.
