Amanda Clarke, who now goes by the name of Emily Thorne. When she first arrives at the Hamptons, she seems like a cute and friendly "girl next door". However, the reason she changed her name is because her main motive is to seek revenge on her father's closest friends and coworkers, who had sentenced him to a life time of prison, and eventually death, for a crime that he had not committed.
Emily: Emily Thorne no longer exists.
Nolan: It's the end of an era.
Emily: Tell Margaux to leave Jack and Carl alone. She is doing everything she can to tear that family apart.
Victoria: Oh, Margaux. What's left of her family is nothing but rubble. She's in mourning.
Emily: Well she's got a really screwed up way of dealing with it.
