"C'mon, wake up, wake up, please..."
Jasper was crouched over Jace's body, one hand spread over the center of his chest, the other hovering above what she assumed were fractured ribs. She was no accomplished healer, but as best she could tell, the worst of his injuries were a broken rib that had punctured his lung. If she could just get that healed, just do enough to keep him conscious until she could get him to someone who actually knew what they were doing...
"Jace, please, wake up," she breathed, feeding magic desperately into his body. It didn't occur to her to worry that, if simply touching his hand had been enough to spark some strange reaction from her power, actually using her magic to heal him might do...something similar.
She didn't have time to consider it. He was dying, and if her magic wasn't enough to get him stable...she didn't know what to do.
