“Haven’t I?” Magnus said, and then smiled at him. “Will, you treat me as a human being, a person like yourself; rare is the Shadowhunter who treats a warlock like that. I am not so heartless that I would call in a favor from a brokenhearted boy. One who I think, by the way, will be a very good man someday. So I will tell you this. I will stay here when you go, and I will watch over your Jem for you, and if he wakes, I will tell him where you went, and that it was for him. And I will do what I can to preserve his life: I do not have yin fen, but I do have magic, and perhaps there is something in an old spell book I might find that can help him.”
“Will and Tessa were in the carriage now, and their driver was snapping the reins. 'Do you think there’s a chance for him?''A chance for who?''Will Herondale. To be happy.'Woolsey sighed gustily and put down his glass. 'Is there a chance for you to be happy if he isn’t?'Magnus said nothing.'Are you in love with him?' Woolsey asked—all curiosity, no jealousy. Magnus wondered what it was like to have a heart like that, or rather to have no heart at all.'No,' Magnus said. 'I have wondered that, but no. It is something else. I feel that I owe him. I have heard it said that when you save a life, you are responsible for that life. I feel I am responsible for that boy. If he never finds happiness, I will feel I have failed him. If he cannot have that girl he loves, I will feel I have failed him. If I cannot keep his parabatai by him, I will feel I failed him.”
“If you do not help me," Tessa said to Jem, "I swear, I will change into you, and I will lift him myself. And then everyone here will see what you look like in a dress." She fixed him with a look. "Do you understand?”
“He's a cousin of some friends of the Lightwoods or something. He's nice. I promise." "Nice, bah. He's gorgeous." Magnus gazed dreamily in his direction. "You should leave him here. I could hang hats on him and things." "No. You can't have him." "Why not? Do you like him?" Magnus's eyes gleamed. "He seems to like you. I saw him going for your hand out there like a squirrel diving for a peanut.”
“It is the mundanes who look at me and see something they do not understand—a boy who is not quite white and not quite foreign either.""Just as I am not human, and not demon either," Tessa said softly.His eyes softened. "You are human," he said. "Never think you are not. I have seen you with your brother; I know how you care for him. If you can feel hope, guilt, sorrow, love—then you are human.”
“If Jem dies, I cannot be with Tessa,” said Will. “Because it will be as if I were waiting for him to die, or took some joy in his death, if it let me have her. And I will not be that person. I will not profit from his death. So he must live.” He lowered his arm, his sleeve bloody. “It is the only way any of this can ever mean anything. Otherwise it is only —”“Pointless, needless suffering and pain? I don’t suppose it would help if I told you that was the way life is. The good suffer, the evil flourish, and all that is mortal passes away,” Magnus said.“I want more than that,” said Will. “You made me want more than that. You showed me I was only ever cursed because I had chosen to believe myself so. You told me there was possibility, meaning. And now you would turn your back on what you created.”
“Did you think I was helping you out of the goodness of my heart? Or am I just the only warlock you know?” (Magnus)…“No,” he said now, “but you are the only warlock we know who happens to be dating a friend of ours.” (Jace)For a moment everyone stared at him-Alec in sheer horror, Magnus un astonished anger, and Clary and Simon in surprise. It was Alec who spoke first, his voice shaking. “Why would you say something like that?”Jace looked baffled. “Something like what?”“That I‘m dating-that we‘re-its not true,” Alec said, his voice rising and dropping several octaves as he fought to control it.Jace looked at him steadily. “I didn’t say he was dating you,” he said, “but funny that you knew just what I meant, isn’t it?”“We‘re not dating,” Alec said again.“Oh?” Magnus said. “So you‘re just that friendly with everybody, is that it?”-pg.241-”
