Please answer this: What is the last name of the person that the narrator calls for help?  Answer the above question based on the context below:  The unnamed Narrator is an automobile recall specialist who is unfulfilled by his job and possessions, and has developed severe insomnia. He finds catharsis by posing as a sufferer of testicular cancer and other afflictions in support groups, remedying his insomnia. His bliss is disturbed by another impostor, Marla Singer, whose presence reminds him he is attending these groups dishonestly. The two agree to split which groups they attend, but not before they exchange contact details on the premise of switching groups at short notice. On a flight home from a business trip, the Narrator meets and interacts with soap salesman Tyler Durden. The Narrator returns home to find that his apartment has been destroyed by an explosion. Deciding against asking Marla for help, he calls Tyler, and they meet at a bar. Tyler says the Narrator is beholden to consumerism. In the parking lot, he asks the Narrator to hit him, and they begin a fistfight. The Narrator is invited to move into Tyler's home: a large, dilapidated house in an industrial area. They have further fights outside the bar, which attract growing crowds of men. The fights move to the bar's basement where the men form Fight Club, which routinely meets for the men to fight recreationally. Marla overdoses on pills and telephones the Narrator for help; he ignores her, but Tyler picks up the phone and goes to her apartment to save her. Tyler and Marla get sexually involved, and Tyler warns the Narrator never to talk to Marla about him. The Narrator blackmails his boss and quits his job.

input question: What is the alias of the person who disables a robot?  Answer the above question based on the context below:  In a technologically-advanced 1939, the zeppelin Hindenburg III moors itself atop the Empire State Building. Aboard the airship is Dr. Jorge Vargas, a scientist who arranges for a package containing two vials to be delivered to Dr. Walter Jennings. The courier looks back while leaving with the vials, to see that Dr. Vargas has vanished. Polly Perkins, a reporter for The Chronicle, is looking into the disappearances of Vargas and five other renowned scientists. A cryptic message leads her to Radio City Music Hall, against the warnings of her editor, Mr. Paley, where she meets Dr. Jennings during a showing of The Wizard of Oz. He tells her that a Dr. Totenkopf is coming for him next. Suddenly, seemingly indestructible robots attack the city. Clearly outmatched, the authorities call for "Sky Captain" Joe Sullivan, the city's hero and Perkins' ex-lover and the commander of the private air force the Flying Legion. While Joe engages the robots with his modified Curtiss P-40 pursuit fighter, Perkins photographs from the street with little regard for her personal safety. He eventually manages to disable one robot; the rest leave thereafter. News reports show similar attacks around the globe. The disabled robot is taken back to the Legion's air base so that technology expert Dex can examine it. Polly follows and convinces Joe to reluctantly let her in on the investigation. Her information takes them to the ransacked laboratory of a dying Dr. Jennings, while an assassin escapes. Just before he dies, Jennings gives Polly the two vials and states that they are crucial to Totenkopf's plans. Polly hides the vials and withholds the information from Joe. They return to the Legion's base just before it comes under attack from squadrons of ornithopter drones. Dex tracks the origin of the signal controlling the drones and notes it on a map before his capture.???
