By the end of chapter 19 in Great Expectations, what are some of the exernal conflicts Pip experiences with others or the environment?
By this point, Pip has several man vs. man conflicts with other characters.
He has had a lifelong conflict with his sister. Having raised him by hand Pip struggled with her abuse and neglect.
He has a developing conflict with his brother-in-law Joe. Although Joe has great care for Pip, his quick answers and failure to report Pip's exciting news demonstrate that he is disappointed to be losing a friend. When Pip had the opportunity to choose a different life, a life other than the one Joe had worked to develop for Pip, Pip left Joe which hurt Joe.
He has a conflict with his environment in that he does not know his benefactor, where the benefactor is, or when the benefactor will reveal his identity to Pip. This will make every new aquaintance a mystery:
Now you are to understand, secondly, Mr. Pip, that the name of the person who is your liberal benefactor remains a profound secret, until the person chooses to reveal it.
This issue with the unknown has been a theme for Pip. He has seen the convict when a child, then later at the bar. Now another strange unknown is in his life.
Pip has a continued conflict with Estella. He does not know why she is so mean to him still. He thinks he understands that this benefactor is Havisham. But, not even audience members know if that is true at this point.
