Task: Question Answering
Input (English): Passage: The film opens at Burger-Matic, where Henry Lever orders a milkshake at the drive-thru. At the window, he tells the attendant, Sally Jackson, that his wife knows about their affair. She asks him if he has also told his wife about her pregnancy. On his way home, he encounters a ferocious wind. It turns out to be an attack helicopter, which runs him off the road. In a panic, he flees through the woods and drops his heart medication. At an outdoor chapel, he sits on a bench as the helicopter hovers in front of him. The pilot, Angus Montier, shoots at the ground near him despite the protests of his copilot and brother, Dorian. The shots scare him enough to cause a fatal heart attack.
Throughout their attack, Dorian and Angus can hear the chatter of Sally and her coworkers. Likewise, they can hear the helicopter pilots on their headsets. The next day, the police inform Beatrice Lever that Henry has died. She appears shocked and crestfallen, when Dorian and Angus arrive. It quickly becomes clear that she encouraged her sons to scare him to death. She is also furious about his affair, and wants revenge on his mistress. Angus and Dorian are worried that the people they heard on the radio might have overheard enough to connect them to his death. They quickly deduce that Burger-Matic is the only location close enough to have been on the same frequency. Angus goads Dorian into getting a job there to ensure that no one is wise to their crime.
Sally is heartbroken at the news about Henry. At work, Dorian bonds with her quickly. He gives her a model helicopter for her baby, and he explains that he and Angus fly them as reservists for the National Guard. She asks him to accompany her to lamaze class, since she doesn't have a partner. Eventually, he takes her to the base to see the helicopter that he flies. As she sits in the cockpit, she tells him about Henry. 
Question: What are the full names of the two people having an affair?
Output (English): Henry Lever.
