Pip decides to go home at once so that he can both apologize to Joe for his behavior and so that he can see the splendid Estella.
Pip decides to stay at the Blue Boar rather than at Joe’s house, because he’s still too embarrassed to be around Joe.
The journey back home is pretty much the carriage ride from hell. There are two convicts who accompany the carriage riders, and Pip realizes that one of the convicts is the very same man who gave him the two pound note all those years ago at the Three Jolly Bargemen.
Pip has to sit right in front of this convict, and, as he is a heavy breather, Pip feels his convict-breath on him the whole ride home. The convict tells his compadre the story of giving a two pound note to a little boy in marsh country many years ago, and Pip realizes that he is relating the exact same story.
He is freaked out that the convict is going to recognize him, even though that’s highly unlikely, Pip jumps ship (or carriage, rather) at the first possible stop.
When he gets to the Blue Boar, everyone there recognizes him as the young man for whom Pumblechook is responsible. It appears that Pumblechook has told everyone, everywhere that he is responsible for Pip’s fortune and rise in society. Pumblechook is annoying.
Pip is convinced that, if he were to go to the North Pole, people there would still recognize him as Pumblechook’s mentee.
