Glinda: I know you don't want to hear this, but someone has to say it... You are out of control! I mean, come on! They're just shoes, let it go! Elphaba, you can't go on like this.
Elphaba: I can do anything I want. I am the Wicked Witch of the West!

boq

In the musical, Boq is the love interest of Elphaba's younger sister, Nessarose (who would later become The Wicked Witch of the East). However, the feeling is not mutual; Boq only became involved with Nessarose in hopes of impressing Galinda, whom he truly has his heart set on. Unfortunately for him, though, Galinda has so little regard for him that she cannot remember his name (calling him Bick). When Nessarose eventually becomes the governor of Munchkinland, she uses her power to enslave Boq as her personal servant. When Boq confesses his love for Glinda, Nessarose becomes extremely angry at him. At that point, she casts a spell on him from Elphaba's spell book, but misspronounces it. This causes Boq's heart to shrink until it is completely gone. In a desperate attempt to save Boq's life, Elphaba turns Boq into the Tin Man. Unlike in the novel, Boq plays quite a condensed role in the staged production.
