Mrs. Linde guesses that Dr. Rank is the mysterious source of Nora’s loan, but Nora denies the charge. Mrs. Linde remarks that Nora has changed since the previous day. There are way too many secrets here. Mrs. Linde feels that a little honesty might help the situation. Torvald, would take care of the debt if he was told about it and Nora would no longer have to be constantly covering for herself and asking Torvald to save Krogstad's job.
