Estella
Estella is an orphan, like Pip and her adopted mother is Miss Havisham. Due to Miss Havisham's misery over her broken heart, Estella has been raised in a way that makes her incapable of showing affection. Estella is the reason why Pip wanted to become a gentleman and move out of his social class. Pip cares for Estella very much and would do anything for her. Overall, Estella is a very mysterious character that we don't know everything about.
