Estella

So, he does meet with Estella and it does seem that Miss Havisham is trying to set them up, but in her twisted mind, she's probably just setting Pip up to suffer, as a revenge for how she was left to suffer. Also, we find out that Estella's last name is Havisham.  This section is a treasure trove. I'll add to this post. I need to look at it again. Dickens is at the top of his game in understanding relationships and longing here. Estella tells Pip flat out that she doesn't have a heart for love. That she is incapable of loving someone. He also feels beneath her, yet still entranced by her beauty and believing that Miss Havisham has brought them together for marriage, when she is not capable of wishing joy on anyone, particularly not a man. And Estella is a puppet for her to torture men with for her own loss. (And unwillingness to move forward from her earlier betrayal.)
