As in the novel, Elphaba gets tired of Nessarose and leaves her younger sister for good, despite Nessarose's frantic pleas for Elphaba to stay with her. When it turns out that Elphaba had turned Boq into a Tin Man, so that he can live without a heart, a desperate Nessarose places all the blame on her older sister, and a horrified Boq runs away, leaving Nessarose on her own. Thus, she is unable to walk, and comes to regard her whole existence as a "sorry life."
