Task: Question Answering
Input (English): Passage: 1953: Through the course of a Colorado autumn and winter, Mary Spencer and Fred Wilson lead an idyllic existence. Mary drops out of college (with 6 months to go) to marry Fred. Their perfect wedding mirrors the happy endings of the films Mary loves.
1969: It is the Wilsons' 16th wedding anniversary. On his way to work, Fred, a successful tax consultant, tells their maid Agnes that he has found vodka hidden in Mary's wardrobe and asks Agnes to keep an eye on his wife. Mary sets out for the beauty parlour. At an airline office, however, Mary buys a one-way ticket to Nassau, Bahamas looking for an escape from her dull and unhappy suburban life.
On the flight she recalls the horrors of last year's anniversary party, when Fred had drunkenly flirted with a blond divorcee, and she had taken refuge in the bottle and a rerun of Casablanca. At a stop-over, she calls home and learns this year's anniversary party has been a different sort of disaster. Her teenage daughter Marge is scared by Mary's call, as it reminds her of the time she had found her mother unconscious after an overdose.
En route to Nassau, Mary meets Flo, an old college friend she has not seen since 1953. While Mary settled down to married life, Flo has been the mistress of a series of married men and lives a rather carefree and hedonistic lifestyle and has fully embraced the sexual revolution. She is on her way to Nassau to meet her latest beau, Sam. Mary tells her she has had to get away from Fred, so Flo promises to look after her. 
Question: What is the last name of the person who got drunk and flirted with a blond?
Output (English): Wilson.
