How does Mrs Christine linde sperks the central conflict to the play

Mrs. Christine Linde comes back into Nora's life after losing her husband and mother. She worked hard to support her helpless mother and two younger brothers since the death of her husband. Now, with her mother dead and her brothers being adults, she is a free agent. Pressed for money, Mrs. Linde successfully asks Nora to help her secure a job at Torvald's bank. Ultimately, Mrs. Linde decides that she will only be happy if she goes off with Krogstad. Her older, weary viewpoint provides a foil to Nora's youthful impetuousness. She perhaps also symbolizes a hollowness in the matriarchal role. Her relationship with Krogstad also provides a point of comparison with that of Nora and Torvald.
