Elphaba felt racked with guilt as she slipped through the shadows of Kiamo Ko with Fiyero by her side. Though she was relieved to be free, to be alive, each step towards safety was putting her one step further from Glinda. She hated having to deceive her, and Glinda's sobs after the "melting" still echoed loudly in Elphaba's ears.
Elphaba desperately wished Glinda could somehow find some source of happiness, some peace in the situation. Glinda had once left Elphaba to struggle on her own, all those years ago, and now Elphaba felt she was doing the same to her.
