Joe and her husband Joe who is a blacksmith. Estella is very disgusted by him and hurts him very deeply by calling him a "common boy" and calling him stupid for not having as much education she had. Estella seems like an unreachable star in the sky and this influences Pip to a great extent by making him want to become more educated and to become a gentlemen so he can have her. He becomes very ashamed of his family who he feels are very coarse and common. When he gets a secret benefactor that offer to make him a gentleman he immediately seizes the opportunity. Pip assumes that the benefactor is Miss Havisham who wants make him a worthy husband for Estella.
Estella's character is used by the author Charles Dickens to represent everything that Pip wants out of life and probably can never have, in other words everything that is unreachable for him. Also Estella represents everything that Pip should never want in a friend. This brings in the total opposite of Estella which is Pip's good friend Biddy. Biddy represents everything that Pip can actually have out of life and be content with. She will always remain loyal to Pip and is everything that he could ever dream of in a friend. However she doesn't remain the same throughout the whole story because when Pip deserts her and his family to become a gentleman she becomes a little resentful that he would be so unappreciative and heartless to leave them like that for his need to become uncommon and impress Estella, who has never done anything for him. Estella also doesn't remain the same throughout the story either. When Pip becomes a gentleman and they both become older she becomes more mature and befriends Pip but still is uninterested in him and seems to pity him at times. Even though Estella isn't acting of her own free will she still hurts Pip and it seems that she doesn't want to. She always warns him that she has no heart and tries to tell Pip that it would be better for him if he would just leave her behind.
