Read the excerpt from act 2 of A Doll's House . Nora: [quickly] He mustn't get the letter. Tear it up. I will find some means of getting money. Krogstad: Excuse me, Mrs. Helmer, but I think I told you just now— Nora: I am not speaking of what I owe you. Tell me what sum you are asking my husband for, and I will get the money. Krogstad: I am not asking your husband for a penny. Nora: What do you want, then? Krogstad: I will tell you. I want to rehabilitate myself, Mrs. Helmer; I want to get on; and in that your husband must help me. For the last year and a half I have not had a hand in anything dishonourable, amid all that time I have been struggling in most restricted circumstances. I was content to work my way up step by step. Now I am turned out, and I am not going to be satisfied with merely being taken into favour again. I want to get on, I tell you. I want to get into the Bank again, in a higher position. Your husband must make a place for me— Nora: That he will never do! Krogstad: He will; I know him; he dare not protest. And as soon as I am in there again with him, then you will see! Within a year I shall be the manager's right hand. It will be Nils Krogstad and not Torvald Helmer who manages the Bank. Nora: That's a thing you will never see! Krogstad: Do you mean that you will—? Nora: I have courage enough for it now. Krogstad: Oh, you can't frighten me. A fine, spoilt lady like you— Nora: You will see, you will see. Krogstad: Under the ice, perhaps? Down into the cold, coal-black water? And then, in the spring, to float up to the surface, all horrible and unrecognisable, with your hair fallen out— Nora: You can't frighten me. Krogstad: Nor you me. People don't do such things, Mrs. Helmer. Besides, what use would it be? I should have him completely in my power all the same. Nora: Afterwards? When I am no longer— Krogstad: Have you forgotten that it is I who have the keeping of your reputation? [NORA stands speechlessly looking at him.] Well, now, I have warned you. Do not do anything foolish. When Helmer has had my letter, I shall expect a message from him. And be sure you remember that it is your husband himself who has forced me into such ways as this again. I will never forgive him for that. Goodbye, Mrs. Helmer. [Exit through the hall.] What conflict does Krogstad introduce?
