Act III of A Doll's House~ I'm starting off when Torvald gets a card at the door and he's drunk.
Nora: Ok sweetie... Let's put you to bed trying to drag him up the stairs
Torvalad: No, no Nora. What's that card?
Nora: Ummm... Helmer that's a card from our dear old friend Dr. Rank.
Torvald: Ok my little skylark  laughing at her hysterically 
Nora: I think you had too much to drink. Don't you think?
Nora get's Helmer upstairs. She sets Helmer on the bed calls for the maid.
Maid: Yes ma'am
Nora: Yes can you bring me more pillows and sheets please. Also, close the children's door.
The maid leaves and comes back with pillows and sheets.
Torvald: Hey my little song bird.You wanna hear a secret?
Nora: Sure what is it?
Torvald: You know Mrs. Linde?
Nora: Yes I do
Torvald: When your not home me and Mrs. Linde have a lot of fun alone together.
Nora: Really?
Torvald: Yes
Nora: So your saying that you've been cheating on me with her?
Torvald: Yes I am and its so fun
Nora: I will be right back..
Nora leaves the room and goes down stairs to the kitchen and grabs a butcher knife. She comes in the room and Torvald is sound asleep.
Nora: Sorry hun I have to do this..
She puts the pillow of his face and grrabs the knife and starts stabbing him repeatly

These two characters are Nora and Krogstad. I think what's happening in this scene is when Krogstad comes to visit Nora about how she forged her father's signature. At the time Nora told her old friend Mrs. Linde that she raised the money for her once sick husband to go away when Mrs. Linde thought Nora burrowed the money from her father.
Krogstad knows how this is a big deal because he once did the some thing back in the day. If Nora doesn't pay up Krogstad will tell her husband about what she did or start blackmailing her. According to Nora its not a big deal. A quote from Act I is " A barrister's life is such an uncertain one- especially when he won't touch any case that isn't absolutely respectable" (page 155)

Information about the author of "A Doll's House"

Henrik Ibsen was born on March 20, 1828, in Skien, Norway. In 1862, he was exiled to Italy, where he wrote the tragedy Brand. In 1868, Ibsen moved to Germany, where he wrote one of his most famous works: the play A Doll's House. In 1890, he wrote  Hedda Gabler, creating one of theater's most notorious characters. By 1891, Ibsen had returned to Norway a literary hero. He died on May 23, 1906, in Olso, Norway. As a child, Henrik showed little sign of theatrical genius. His father was a successful merchant and his mother painted, played the piano and loved to go the theater. He grew up in the small Norwegian coastal town of Skien as the oldest of five children born to Knud and Marichen  Ibsen. At 15, Ibsen stopped school and went to work. Ibsen had long and seemingly marriage with Suzannah Daae Thoresen (www. Biography.com/ henrik ibsen)

I think the title of the play relates to what the play about that it's going to be a little girl who buys a doll's house or receives a doll's house for a gift. But as soon as she gets the doll house there's something about the doll house she loves but everyone knows that there is always a legend behind every toy. Themes and symbols that the plays focus on is T/T and T/W.
