In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: In 1987, James Brennan plans to have a summer vacation in Europe after graduating with a comparative literature degree from Oberlin College and to attend a journalism graduate school at Columbia University when his holidays end. A few days after his graduation, his parents advise him to seek a part-time job rather than going to Europe when they unexpectedly announce that financial problems have taken a toll on them and they would be unable to financially support him.
James gets a job at Adventureland, a local amusement park in his hometown of Pittsburgh, Pennsylvania, where his childhood friend Tommy Frigo works. Assistant manager Bobby assigns James to the games area. He meets his co-workers: sarcastic Joel; Bobby's wife and park manager Paulette; Sue O'Malley; Mark; the alluring Lisa P.; and the park's technician, Mike Connell, a part-time musician. Another games worker, Emily "Em" Lewin, saves James from being stabbed by a lying, cheating customer.
With her father and stepmother away, Em throws a party and gets to know James. During the conversation, Em persuades James to join her in the house's swimming pool. After Em leaves the pool, James follows only to jump back into the water in humiliation when Frigo announces to the partygoers that he saw James having an erection while leaving the pool. After the party, Connell, who has been having an affair with Em, comes over to further pursue it.
What is the nickname of the person that's in a relationship with the musician?
