How does the author use foreshadowing in Four Major Plays?

From Torvald's first moments in the play, A Doll's House, he appears to be a patronizing, repressive monster. Examples of this last element include Torvald's anger at the idea of taking out a loan, which foreshadows Torvald's anger in Act III when he discovers what Nora's done. Another piece of foreshadowing is Nora's early lies. When Torvald asks whether she's brought candy into the house, for example, she lies and says she hasn't. These lies foreshadow later revelations about her lies about the loan - lies that, in turn, define who she is at the beginning of her journey of transformation, and why that journey is necessary.
