Jurigs a dynamic character has undergone many changes. Name a few from this chapter Does Jurigs realize how he has changed?

Jurgis keeps his job after the elections and begins a new life as a “sporty” young man. He wears nicer clothes now, and stays out until all hours of the night, gambling and drinking and going to parties.

No, I think he's enjoying the changes, but he doesn't realize he has changed.
