“You haven't broken his heart yet, have you?""No," Tessa said. Just torn my own in two. "I haven't broken his heart at all.”

“I used to think if I married Master Jem—” Sophie picked at the blanket, then looked up and smiled bleakly. “You haven’t broken his heart yet,have you?”“No,” Tessa said. Just torn my own in two. “I haven’t broken his heart at all.”

“And broken both your hearts? How would that have benefited me? You are as dear to me as another half of my soul, Jem. I could not be happy while you were unhappy. And Tessa—she loves you. What sort of awful monster would I be, delighting in causing the two people I love the most in the world agony simply that I might have the satisfaction of knowing that if Tessa could not be mine, she could not be anybody’s?”

“Alec?" Magnus was staring at him. He had dispatched the remaining Iblis demons, and the square was empty but for the two of them. "Did you just- did you just save my life?" Alec knew he ought to say something like, Of course, because I'm a Shadowhunter and that's what we do, or That's my job. Jace would have said something like that. Jace always knew the right thing to say. But the words that actually came out of Alec's mouth where quite different- and sounded petulant, even to his own ears. "You never called me back," he said. "I called you so many times and you never called me back." Magnus looked at Alec as if he'd lost his mind. "Your city is under attack," he said. "The wards have broken, and the streets are full of demons. And you want to know why I haven't called you?”

“Just take the weapon you hold in your hand and drive it through his heart," Valentine's voice was soft. "One simple motion. Nothing you haven't done before."Jace met his father's stare with a level gaze. "I saw Agramon," he said. "It had your face.""You saw Agramon?" The Soul-Sword glittered as Valentine moved toward his son. "And you lived?""I killed it.""You killed the Demon of Fear, but you won't kill a single vampire, not even at my order?"Jace stood watching Valentine without expression. "He's a vampire, that's true," he said. "But his name is Simon.”

“Jem--Jem is all the better part of myself. I would not expect you to understand. I owe him this.""Then what am I?" Cecily asked.Will exhaled, too exasperated to check himself. "You are my weakness.""And Tessa is your heart," she said, not angrily, but thoughtfully. "Not a fool, as I told you," she added at his startled expression. I know that you love her.”

“I am stronger when Tessa is here, you see. I told it to you," said Jem, still in the same soft voice.At that, Will did duck his head so that Tessa could not see his eyes. "I see it," he said.”
