A Doll's House: Act II

I noticed a bit of ignorance on Nora's part in the beginning of act 2 when she refers to Doctor Ranks' illness due to his fathers misdeeds.
 
Nora calls Kristine over to have her help with her dress. This is her friend that she has neglected to keep in contact with and this is what she does when they finally see each other. They're both using each other for their own personal benefit. Same as Doctor Rank who is supposed to be Torvald's best friend but he's flirting and admitting his feelings he's kept for Nora.
