Jack picked up Nicole in his hands as he saw a deep wound on her shoulder. He was terrified as sweat dripped from his forehead, he never thought that his yellow energy would be able to harm Nicole, after all, she was a powerful girl.
She was the queen of death that even Vieva was a bit wary of, so her being harmed by his energy was something that never came into his mind.
He thought that just like the last time his energy ball would hit her and then disappear, however, now there was a deep wound on her shoulder from which blood was flowing out and he could see that even her eyes were turning drowsy, it was as if she was about to turn unconscious.
