I think that Pip is similar to Alice in relation to the types of adventures they have and how adults in general treat them. Alice has the White Knight who she is friendly with and is friendly in return. We could compare the White Knight to Joe, as characters who both show some compassion to Pip/Alice in a world where no one else cares about them.
However, Joe seems to have more of an impact on Pip than the White Knight has on Alice- plus he's around a lot longer. When Pip tells all the lies about what happened at Miss Havisham's, he confronts Joe and tells him he feels bad about it. Joe gives him the moral advive that he shouldn't tell any more lies in order to "live well and die happy" (72). This is absent from Alice and the White Knight's interaction, as Joe seems to be a confidant, advisor, and more of a consistent influence than the White Knight.
