chunk: In the second act, which also takes place at Sir Robert's house, Lord Goring urges Sir Robert to fight Mrs. Cheveley and admit his guilt to his wife. He also reveals that he and Mrs. Cheveley were formerly engaged. After finishing his conversation with Sir Robert, Goring engages in flirtatious banter with Mabel. He also takes Lady Chiltern aside and obliquely urges her to be less morally inflexible and more forgiving. Once Goring leaves, Mrs. Cheveley appears, unexpected, in search of a brooch she lost the previous evening. Incensed at Sir Robert's reneging on his promise, she ultimately exposes Sir Robert to his wife once they are both in the room. Unable to accept a Sir Robert now unmasked, Lady Chiltern then denounces her husband and refuses to forgive him.
