On his trip to Satis House in chapter 44, what favor does Pip request of Miss Havisham? What does Pip tell Estella and what new information does she reveal to him?

Pip asks her to be kind to Mr. Pocket and Herbert Pocket. Pip confides in Estella that he doesn't see her motives as entirely evil. He also tells Estella he is in love with her. Estella says that she is fed up with the word "love" and that she intends to marry Drummle.
