As Mr. Jaggers' clerk, Wemmick models his character on Mr. Jaggers while in the office where he is rational, unemotional, and money-minded. Yet when Wemmick is at home, his personality changes dramatically and he is warm, empathetic, domestic, and nurturing towards his elderly father, the Aged. Pip and Wemmick are good friends outside of the office but maintain a strictly professional relationship in front of Mr. Jaggers.
