Task: Question Answering
Input (English): Passage: Irish Catholic Mickey Fitzpatrick is a New York City taxi driver, unhappy over an act of infidelity committed by Heather, his ex-fiancée. His brother, Francis, is a Wall Street stock investor married to Renee, though she is frustrated by his lack of desire for sexual relations – not knowing that he is in a heated affair with Heather.
During weekends, Mickey and Francis visit their parents' home on Long Island. Their father, Frank, is locked in old-school, low-key, sexist ways, and is always telling Mickey and Francis what to do, yet also advises them to always go for what drives them to succeed.
Driving his cab, Mickey picks up Hope, an NYU art student headed to the airport. They click within seconds and she asks him to drive her to New Orleans. They become infatuated and impulsively marry the next day, returning to New York two days later to tell Francis and Renee. Francis is upset, mostly because he was not asked to be best man. Mickey moves in with Hope, but later becomes disillusioned with her bohemian lifestyle, including frequent power cuts in their ramshackle apartment. Francis grows concerned that he is being unfair to Heather by continuing to stay with Renee. At the same time, Renee's Italian-American family, mostly her younger sister Molly, suggest the problem with Francis' lack of interest in her is that he may be gay, so she asks Mickey and Frank to confront him. He denies being gay, but admits to being unfaithful. 
Question: What's the full name of the person whose former fiancee is sleeping with his brother?
Output (English): Mickey Fitzpatrick.
