Answer:
Here are some key events in act 4:
1. The formally dressed trio of Eliza, Higgins, and Pickering go to Higgins' house at midnight. This is following the garden party, dinner party, and opera.
2. Higgins feels irritated after attending the events with Eliza and is thankful that it is over.
3. An upset Eliza throws Higgins' slippers at him, saying "I've won your bet for you, haven't I? That's enough for you. I don't matter, I suppose."
4. Higgins continues to treat Eliza poorly, and Eliza calls Higgins a "selfish brute" who believes she came from the gutter. Eliza lunges at Higgins after she is referred to as "the creature" and later as "a cat"
5. Eliza says to Higgins, "There can't be any feelings between the like of you and the like of me." This angers Higgins and he calls Eliza ungrateful. Eliza looks satisfied at having upset Higgins.
Explanation:
You may need to explain why these are key events:
1. Eliza successfully passed as a noble lady at the garden party, dinner party, and opera, meaning that Eliza won Higgins' bet for him.
2. Higgins views the night's events as an "experiment" and is not seeing Eliza as a person nor is he acknowledging her feelings. He is thankful the night is over because the experiment was getting boring and Eliza was irritating him.
3. Eliza is upset and angry after being treated as an experiment all night and feels that she has been used for Higgins' gain.
4. Higgins' use of name-calling highlights his misogyny and his opinions about the lower class.
5. Eliza says that she is different from Higgins because of their different social classes. She says this to make Higgins upset.
