When Pip turned 21 he came into full possession of his ‘fortune’.

Pip has a birthday dinner with Jaggers and Wemmick. Afterwards he goes to Walworth (Wemmick’s home) because Wemmick is his friend and he wants advice about setting some money aside to help support Herbert start his insurance business.

Wemmick’s advice contradicts itself the second time it is given. The first set of advice is given as an officer in Jagger’s office and is professional. The second set is given as a friend.

Pip is starting to change here. He is starting to think about how his money could be used for good, and thinking about helping raise other people up. He wants to use his money to help Herbert, so that Herbert can then marry Clara.
