The home is further disrupted by the return of Lantier, who is warmly welcomed by Coupeau - by this point losing interest in both Gervaise and life itself, and becoming seriously ill. The ensuing chaos and financial strain is too much for Gervaise, who loses her laundry-shop and is sucked into a spiral of debt and despair. Eventually, she too finds solace in drink and, like Coupeau, slides into heavy alcoholism. All this prompts Nana - already suffering from the chaotic life at home and getting into trouble on a daily basis - to run away from her parents' home and become a casual prostitute.
