A Doll's House
How we cite our quotes:
KROGSTAD: "Or perhaps that you have some expedient for raising the money soon?
NORA: "No expedient that I mean to make use of." (2.259-2.260)
Nora is referring to her decision not to borrow money from the lovesick Dr. Rank. Why doesn't she want to borrow it from him? Does she not want to manipulate him? Or does she feel like she'd be selling herself in some way?
KROGSTAD: "I shall only preserve it--keep it in my possession. No one who is not concerned in the matter shall have the slightest hint of it." (2.263)
Rather than blackmailing the Helmers for money, Krogstad is seeking to regain his reputation, showing that which he truly values as a character.
KROGSTAD: "How will you be able to prevent it? Am I to understand that you can pay the balance that is owing?" (2.257)
Nora's debt gives Krogstad power.
