Some time has passed, and Elphaba's exploits have earned her the title "The Wicked Witch of the West" ("No One Mourns the Wicked (Reprise)"). Glinda and Morrible hold a press conference to announce Glinda's surprise engagement to Fiyero ("Thank Goodness"). Meanwhile, Elphaba arrives at the governor's residence in Munchkinland seeking refuge. Nessarose, now the governor following their father's suicide, criticizes Elphaba for not using magic to help her to overcome her disability. To assuage her feelings of guilt, Elphaba enchants Nessarose's jeweled shoes, turning them from silver to ruby red and enabling her to walk. Boq, who is now Nessarose's servant, is summoned and reveals that his affection for Nessarose was put on and that his heart lies with Glinda. Furious, Nessarose miscasts a spell from the Grimmerie, causing Boq's heart to shrink. While Elphaba attempts to save him, Nessarose reflects on how her obsession with Boq has led her to oppress the Munchkin people ("The Wicked Witch of the East"). Elphaba saves Boq by turning him into the Tin Man – horrified, Nessarose lays the blame on Elphaba.
Elphaba returns to the Wizard's palace to free the rest of the winged monkeys. The Wizard attempts to regain her favor by agreeing to set them free ("Wonderful"). Upon discovering a now-speechless Doctor Dillamond among the monkeys, Elphaba rejects his offer and attempts to escape, running into Fiyero in the process. Confirming his true love for Elphaba, he runs off with her. Glinda sees this and is crestfallen that she has been betrayed by those closest to her ("I'm Not That Girl (Reprise)"). In an attempt to finally capture Elphaba, Madame Morrible decides to create a cyclone that will endanger Nessarose.
In a dark forest, Fiyero and Elphaba express their mutual and passionate love ("As Long As You're Mine") but are interrupted when Elphaba senses that her sister is in danger. She flies off to help but is too late, arriving just after Dorothy's house has landed on Nessarose, killing her. The palace guards capture Elphaba, but Fiyero intervenes and tells them to "Let the green girl go!" allowing Elphaba to escape before surrendering himself. The guards take him to a nearby cornfield to be tortured until he tells them where Elphaba has fled. At one of Fiyero's castles, Elphaba tries to cast a spell to save Fiyero's life but, thinking she has failed, she begins to accept her notorious reputation as "wicked" ("No Good Deed").
Meanwhile, Boq and the citizens of Oz prepare a witch-hunt ("March of the Witch Hunters"); Boq claims that Elphaba turned him into the Tin Woodman as an act of evil, while the lion cub that Elphaba and Fiyero freed at Shiz is also at the gathering and turns out to be the "Cowardly" Lion. Seeing the witch-hunt and realizing that Nessarose's death was no accident, Glinda travels to Elphaba and Fiyero's castle to persuade her to let Dorothy go, but she refuses. Elphaba makes Glinda promise not to clear her name and to take charge in Oz. She agrees, and the two confirm a true friendship ("For Good"). As the mob arrives at the castle, Dorothy throws a bucket of water on Elphaba, apparently melting her, while Glinda leaves with the Grimmerie.
In recapitulation, it is revealed that the Wizard is actually Elphaba's father. Glinda orders the Wizard to leave Oz in his balloon, and sends Morrible to prison, before preparing to address the citizens of Oz, returning to the opening scene of the show. Meanwhile, Fiyero, whom Elphaba had turned into the Scarecrow, opens a trap door in the castle; Elphaba, very much alive, emerges, and the two are reunited. Fiyero tells Elphaba that if the two of them want to be safe, no one must ever know that she is alive. Glinda addresses the citizens of Oz, proclaiming that she would like to be "Glinda the Good" as she will reform the government. Elphaba and Fiyero leave Oz, as Glinda celebrates with the citizens of Oz ("Finale").
