Stanley encounters McCann and the two talk. McCann is determined to stop Stanley from leaving the house. Stanley's behaviour and speech start to become erratic. He denies the fact that it is his birthday, insists that Meg is mad for saying so, and asks McCann if Goldberg told him why he has been brought to the house. Goldberg enters and sends McCann out to collect some whiskey that he has ordered for the party. When McCann returns, he and Goldberg interrogate Stanley with a series of ambiguous, rhetorical questions, tormenting him to complete collapse. Meg then enters in her party dress, and the party proceeds with a series of toasts in Stanley's honor. Lulu then arrives and engages with Goldberg in romance. The party culminates with a game of blind man's buff, during which McCann further taunts Stanley by breaking his glasses and trapping his foot in the toy drum. Stanley then attacks Meg and, in the blackout that immediately follows, attacks and attempts to rape Lulu. The act ends with Goldberg and McCann backing the maniacally laughing Stanley against a wall.
