At the center of Wicked is the friendship between Cynthia Erivo’s Elphaba and Ariana Grande-Butera’s Glinda, even as their story devolves into a complicated mess of romantic entanglements with other characters. Wicked‘s cast also includes the rogue prince Fiyero, brilliantly played by Jonathan Bailey in the movie adaptation, who immediately enters a romantic relationship with Glinda upon arriving at Shiz University. However, those familiar with the source material and the relevant tropes can probably understand what Elphaba and Fiyero’s growing connection and the future Wicked Witch’s forlorn song “I’m Not That Girl” mean for the story.
