You can learn a lot about Jaggers from the description of his servant. When Pip says he knows not wether a “diseased affection of the heart caused her lips to be parted”, and her face “to bear a curious expression of suddenness and flutter”, infers that she looks afraid and nervous. This is probably because Jaggers abuses her, mentally or physically. This pointed if further proved when Jaggers “exposes” her wrists. He forcefully grabs her arm and she doesn’t resist ( this implys that she doesn’t stand up against him ), and shows his guests the scars on the inside of her arms. Pip tells us that her wrists are “much disfigured” and “scarred”. This could mean two things. Either Jaggers himself abuses her, or he mentally abuses her and makes her want to kill herself. Jaggers is a bully and treats his inferiors like his slaves.
