The great San Francisco earthquake destroys vast swathes of the city including the small apartment where his parents were sleeping.
At the dinner, Dan enjoys the company of Wo's daughter, May Ling, laughing and feeling more at ease than he had since his first days with Jean.

Doing so before the cargo market collapses, the company greatly profits and uses the money to start a classy department store.
Unable to honor his deposits due to the bank run, his friend dies of a heart attack.
As the heir and subsequent chairwoman of the Seldon Bank, Jean calls the loans that are keeping Levy and Lavette afloat.
Bereft of all his money and torn inside by the emotional destruction of his world, Dan wanders the streets as a vagabond in search of work and even spends three months in prison after fighting off some muggers.
