What does Nepommuck say Eliza?

Nepommuck, in George Bernard Shaw's play "Pygmalion," refers to Eliza Doolittle as a "duchess" in a mocking tone, highlighting the transformations she undergoes in her speech and demeanor. He claims to recognize her as a lady of high society, suggesting that her new persona is superficial and ridiculing her attempts to fit into that world. His comments underscore the play's themes of class distinction and the superficial nature of social status.
