When Eliza emancipates herself – when Galatea comes to life – she must not relapse. She must retain her pride and triumph to the end. When Higgins takes your arm on 'consort battleship' you must instantly throw him off with implacable pride; and this is the note until the final 'Buy them yourself.' He will go out on the balcony to watch your departure; come back triumphantly into the room; exclaim 'Galatea!' (meaning that the statue has come to life at last); and – curtain. Thus he gets the last word; and you get it too.
