Act 2
In Act II, Walter enters the living room and dances with his wife, and then begins to playfully tease his sister about her new ideas, calling her "the chairman of the Committee on Unending Agitation" because she is always talking about race. Beneatha takes the teasing in stride and answers the doorbell.
