What interaction takes place between Henry and Natalie in Act 2, Scene 6?

Henry again asks Natalie to the dance ("Hey #2," a reprise of "Hey #1") and an argument almost erupts, but Henry defuses it by saying he'll come by the following night to take her to the dance. "If you show," he says, "then we'll go. If you don't, we'll see." She comments that he doesn't give up, he asks her to not give up on him, and they say goodbye.
