JJ introduces Sidney to the powerful and sinister Police Detective Kello. JJ gets Sidney clients, and urges his new friend to “keep the ‘O’ and change his name to Falco.” Life’s great! ("Laughing All The Way To The Bank"). Sidney can’t believe his new friendship. The life he's dreamed of is here. ("At The Fountain"). Weeks later, before dawn, at St. Patrick's Cathedral, in the presence of the Almighty, it's payback time. JJ makes Sidney (the former altar-boy) swear he will follow Susan and report on all that he sees. Susan and Dallas are in bed ("Don't Know Where You Leave Off") Susan's agonized. She can’t tell JJ about their romance. JJ would never accept her loving a nobody like Dallas. Dallas gives her an ultimatum. He's back from his latest gig in Philadelphia in three weeks. Tell JJ by then. Dallas says goodbye to Susan at Penn Station with an epic kiss, seen by Sidney. When Susan sees him, Sidney admits he's following her on JJ's behalf. He advises her to drop this nobody Dallas. Susan reminds Sidney how much she helped a nobody like him. In return, she asks Sidney to take on Dallas as a secret client and make him a somebody ("What If"). Susan takes Sidney home to JJ's penthouse. JJ regales Sidney with stories about Susie's childhood, their life together and how much everyone loves his little sister ("For Susan"). Sidney, seeing how oppressive JJ's love is to Susan, feeds JJ an item about a great young piano player named Dallas Cochran who needs a break. JJ will print it. Susan is silently grateful. When Sidney leaves, JJ asks Susan to dance like they used to when she was a little girl. When she rejects him, JJ suspects Susan of seeing someone and counts on Sidney to tell him who that someone is. Thanks to JJ's rave, Dallas is in New York headlining at the hip Cafe Elysian ("One Track Mind"). JJ proudly introduces Susan to his discovery, Dallas. Then he sees Susan's loving reaction. Sidney tries to hustle JJ out of the club. Tony from the Voodoo has stopped by to see Dallas’ success, Tony unwittingly drops the bombshell that Susan and Dallas have been an item for a while. JJ is incensed at having been duped by Sidney. Nobody lies to JJ. Sidney is trapped.
