what is pip's first reaction to his strange visitor and what is his horrible realization?

A rough sea-worn man of sixty comes to Pip's home on a stormy night. Pip invites him in, treats him with courteous disdain, but then begins to recognize him as the convict that he fed in the marshes when he was a child.

The man reveals that he is Pip's benefactor. He has been living in Australia all these years and making money as a sheep herder. But since the day that Pip helped him, he swore to himself that every cent he earned would go to Pip.

"I've made a gentleman out of you," the man exclaims. Pip is horrified. All of his expectations are demolished. He has been living his life off the hard workings of a convict. There is no grand design by Miss Havisham to make Pip happy and rich, living in harmonious marriage to Estella.
