Please answer the following question: What is the last name of the person who was delighted by Nick's song and dance?  Answer the above question based on the context below:  Nick Rivers, an American rock star, travels to East Germany (which is represented as like Hitler's regime) to perform at a cultural festival, which secretly serves the East German government as a diversion for a military operation with the intent of reuniting Germany under their rule. At a dinner, Nick encounters Hillary Flammond, a member of the local resistance movement, attempting to avoid the authorities. He pretends to be her date to get to know her, and performs an impromptu song and dance, mistakenly thinking he was asked to do so, to the delight of Hillary and the diners but to the annoyance of General Streck, the mastermind of the "reunification" plot. Nick later sees Hillary at a ballet, where she expects to rendezvous with the resistance leader but she is met by the police instead. Nick saves her and they try to escape, but Nick turns himself in so that Hillary can get away. He is taken to a prison where he is questioned and tortured, but he knows nothing and does not break. In an escape attempt, he ends up in the secret prison lab of Dr. Paul Flammond, a brilliant scientist developing the "Polaris naval mine", a device that can destroy the entire NATO submarine fleet as part of the government's plot. The Germans force him to work by threatening to kill his daughter Hillary. Nick is recaptured and scheduled for execution.
Answer:
Flammond
