Having lost her chaperone, Ama Clutch, during the train ride to Shiz, Galinda has no one to represent her in roommate negotiations. Refusing to bunk with the common girls in the group dormitory (the Pink Dormitory), Galinda rooms with seventeen-year-old Elphaba, with whom she initially does not get along very well. Elphaba is not interested in socializing, and Galinda, who descends from the noble Arduenna Clan of Gillikin, is more interested in climbing the social ladder than becoming friends with her green roommate. Later, Galinda decides to mock Elphaba by making her wear an unflattering hat. When Elphaba looks pretty anyway, Galinda says so, partly horrified that she talked to the "green girl." They start talking about evil, and Elphaba teaches Galinda how to think. They start attending Doctor Dillamond's biology lectures together.
