She had to get away from Galinda. She needed something different, something more drastic, which most likely meant killing her. So instead of going for a knife or something that would do lethal damage. She used the shards of ice spell to generate one larger, sharp icicle. She held it in one hand and was getting ready to stab Galinda with it when the blonde looked up at her with a weak smile. When the blonde went limp in her arms, Elphaba froze.
A second later, she pinched her eyes shut and shook her head a bit, then when she opened them, she looked at Galinda again. The girl was unconscious, but it seemed more like she was dead. She then looked at her left hand, which held the icicle that was pointed at Galinda. Her eyes went wide, and then she noticed the blood. "Oh Oz," she whispered as she dropped the icicle and held Galinda. "What have I done?" She fell to her knees, clutching Galinda close to her, tears welling up in her eyes.
"Galinda, wake up. Please..." She gently shook the blonde. "Please wake up..." She pleaded, her voice cracking with realization. "Oh sweet Oz....I killed her..." Elphie clung to Galinda, holding her close as she started to cry, feeling herself breaking inside. How could she doe something like this? How could she let herself go this far? In her confusion and hysteria, she hadn't realized Galinda was in fact still breathing. She clung to her and sobbed, burying her face in the blonde's neck.
There were so many things she hadn't told her, and now she never would. It killed her to know she'd done this. She'd never forgive herself for this. Oh if only she'd just stayed away from people, never made friends, maybe none of this would have ever happened. She should have shut herself away from the world after Jack had left after getting her to finally trust him and open up to him. Now? She definitely wouldn't open up ever again. She couldn't when this is what she did to the one she loved.
After a couple minutes, she pulled her head away and sat up, looking down at Galinda. It was then that she noticed the rise and fall of her chest. "Oh sweet Oz!" She glanced around for her broomstick. She spotted it not far away. She didn't know Thor was near otherwise she would have called for him to help. So instead, she would fly them home as fast as she possibly could. "It'll be okay, Galinda. Just hold on. I'll get you home, I swear." She wiped the tears from her cheeks, though they were only replaced with fresh ones.
