Differences between the book in the Thenadier family
Eponine is shown to be friends with Marius. That is not true. She is also known to have no siblings. In reality, she has a sister, Azelma, and three brothers, Gavroche, and two unamed small ones. Madame Thenadier dies in jail, but the musical does not show that. Azelma is not even shown in the musical.
