"The Plot Thickens " Act 2

In act 1 Nora was portrayed as a devious little child that only loves money and macaroons and forged her father signature. Act 2 Is a whole new ballgame. Nora Starts to panic even more! The thought of her family drowned in lies and forgeries, she thinks this cant possibly be happening to her. Nora isn't ratted out, but Torvald finds out about the trip she planned to Italy for him. Also Dr. rank, which is a family friend, finds out he has consumption of the spine.
Halfway through the act Krogstad threatens to tell torvald she forged a signature if Nora doesn't tell Torvald to not fire Krogstad. Basically blackmailing Nora. Later on in the act krogstad gets fired and He places a letter in their mailbox so that torvald can get it. Nora then sends Mrs. Linde over to Krogstads to tell him to take back the letter. Nora is becoming more at unease with herself and is Quoted "Seven hours till midnight. Then twenty four hours till midnight tomorrow. Then the tarantella will be over.......Thirty one hours to live" I think that this could foreshadow some critical in the play signifying the climax of the story.
