In other words, how does Ibsen want you to FEEL at the end of Act 2? Ibsen wants you to feel nervous for Nora. Neither Nora or the reader know what her future holds for her, and that is creating stress and tension. The end of Act 2 ends at a point where everyone is at the edge of their seats waiting for the next big moment to happen. Everyone, even Nora, is nervous and anxious to find out what will happen next.
