“Jace knew he was being cruel, and he barely cared. Hurting people he loved was almost as good as hurting himself when he was in this kind of mood.”

“Sometimes when she looks at him that way he finds himself almost blushing; a feeling so strange he almost doesn’t recognize it. Jace Wayland doesn’t blush.”

“You look happy," he said to Clary. He swiveled his gaze to Jace. "And a good thing for you that she does."Jace raised an eyebrow. "Is this the part where you tell me that if I hurt her, you'll kill me?""No," said Simon, "If you hurt Clary, she's quite capable of killing you herself. Possibly with a variety of weapons."Jace looked pleased by the thought.”

“Memories did one no good, not when one knew the truth in the present. Will was beautiful, but he was not hers; he was anybody's. Something in him was broken, and trough that break spilled a blind cruelty, a need to hurt and to push away.”

“Will had shrugged once, helplessly. He had almost wished Jem would be angry with him. It would have been easier. He'd never felt so small within himself as he did when he faced Jem's expansive kindness.”

“At the moment, he is in shock," said Magnus. "He has believed one thing for five years, and now he has realized that all this time he has been looking at the world through a faulty mechanism - that all the things he sacrificed in the name of what he thought was good and noble have been a waste, and that he has only hurt what he he loved.""Good God," said Woolsey. "Are you quite sure you've helped him?”

“Words were weapons, his father had taught him that, and he'd wanted to hurt Clary more than he'd ever wanted to hurt any girl. In fact, he wasn't sure he had ever wanted to hurt a girl before. Usually he just wanted them, and then he wanted them to leave him alone.”
