Read the excerpt from act 2 of A Doll's House. Mrs. Linde: [goes on sewing. A short silence] Does Doctor Rank come here everyday?

Nora: Everyday regularly. He is Torvald's most intimate friend, and a great friend of mine too. He is just like one of the family.

Mrs. Linde: But tell me this—is he perfectly sincere? I mean, isn't he the kind of man that is very anxious to make himself agreeable?

Nora: Not in the least. What makes you think that?

Mrs. Linde: When you introduced him to me yesterday, he declared he had often heard my name mentioned in this house; but afterwards I noticed that your husband hadn't the slightest idea who I was. So how could Doctor Rank—?

Nora: That is quite right, Christine. Torvald is so absurdly fond of me that he wants me absolutely to himself, as he says. At first he used to seem almost jealous if I mentioned any of the dear folk at home, so naturally I gave up doing so. But I often talk about such things with Doctor Rank, because he likes hearing about them.

Mrs. Linde: Listen to me, Nora. You are still very like a child in many things, and I am older than you in many ways and have a little more experience. Let me tell you this—you ought to make an end of it with Doctor Rank.

How does the conversation between Mrs. Linde and Nora affect the plot?

It has little impact, because Nora and Doctor Rank only interact with each other in one scene.
It has an important impact, because Nora decides that she should leave Helmer for the doctor.
It has a major impact, because it hints at the doctor's feelings for Nora and her attempt at manipulation.
