The Miracle Worker
The scene where London has a breakthrough in learning Spanish from Miss Tutweiller by feeling water on her hands, and Mr. Moseby subsequently calling Emma a miracle worker are references to the story The Miracle Worker, based on Hellen Keller's autobiography The Story of My Life. In The Miracle Worker, Anne Sullivan teaches the deaf-blind Keller to communicate, and includes a scene in which after much frustration and no progress, Keller has a breakthrough when Sullivan connects the word 'water' with the physical sensation of water on the hands.
