Given the following context:  After fleeing from her abusive stepfather, Nola travels to New York City searching for her biological father. She spends her first night sleeping in Central Park, but her luck changes when she is hired by the owner of a small diner. She ends up staying with the frycook/law school student Ben until the real owner of the diner, Ben's landlady Margaret, hires Nola as her assistant for her escort service. Things go well at the escort service until Niles, a billionaire client of Margaret's service, has a bad session. Niles likes to receive rough physical activity from men cross-dressing as women, but only to a point. Wendy, one of Niles's favorites, went a little too far and sent Niles into a rage. Niles demands Margaret rough Wendy up or else he will have it done, along with inducing the police to investigate the escort service. Nola attempts to help by making up Wendy to look battered and bruised, documenting it with photos, then sending her out of the country until Niles can calm down. Niles's informants spot Wendy, no longer wearing the bruise makeup, trying to flee. Niles responds by arranging a subpeona for Margaret to appear before a grand jury and calling Nola directly, threatening her by revealing detailed information about her upbringing. Further events lead Nola closer to finding her real father, but not without the help of a journalist, who is in need of a story on escort services.  answer the following question:  Who helps someone escape after the billionaire gets mad at them?
Nola
