She persuades him to reconsider and he proposes an alternative. If Paul's wife will agree to a divorce and he marries Carol within one week Walter will obtain a quiet divorce. Carol presents Walter's 'deal' to Paul, who regretfully declines, citing respect for his wife.Carol sees as her only choice to accompany Walter to the village, where she meets booze-soaked Tim. He soon introduces her to nuns at the local hospital-convent and Carol begins to re-evaluate her self-absorbed life and character. Working at the convent, Carol learns she is pregnant. She tells Walter she's unsure who is the father and he regrets her honesty. Shortly after, Walter contracts cholera and dies. Carol returns to Hong Kong and an uncertain future.
