In "Great Expectations", what do you learn about Joe's personality and his feelings for Pip from his meeting with Miss Havisham?

Joe is extremely dedicated to Pip, and gets very defensive when people question his motives. He truly loves Pip for Pip, not for what he might be able to do for Joe. We see that he is simple and uneducated, yet loyal and devoted. He sees the best in people, and is sincere in all that he says and does. We also see that Joe has no ambition in and of himself. He wants the best for Pip, but Joe is completely comfortable where he is. He doesn't desire more wealth or status.
