When Torvald finds out Nora's secret, he flips out on her, saying all kinds of terrible things. Krogstad, overjoyed at being with Christine, sends a letter... saying he's not blackmailing them anymore. Torvald forgives Nora, but she doesn't forgive him. She tells him that they're strangers and that they've never had real marriage. She's been his doll, not his wife. The play concludes with Torvald alone in the room. He seems to have a last-minute revelation. Perhaps he's realized what the most wonderful thing of all really is. We don't know for sure.
