“Of course he loves me. I’m his sister.”“Blood isn’t love,” said Magnus, and his voice was bitter.”

“Alec isn’t happy,” said Magnus, as if she hadn’t spoken.“Of course he isn’t,” Isabelle snapped. “Jace—”“Jace,” said Magnus, and his hands made fists at his sides. Isabelle stared at him. She had always thought that he didn’t mind Jace; liked him, even, once the question of Alec’s affections had been settled. Out loud, she said:“I thought you were friends.”“It’s not that,” said Magnus. “There are some people — people the universe seems to have singled out for special destinies. Special favors and special torments. God knows we’re all drawn toward what’s beautiful and broken; I have been, but some people cannot be fixed. Or if they can be, it’s only by love and sacrifice so great it destroys the giver.”Isabelle shook her head slowly. “You’ve lost me. Jace is our brother, but for Alec — he’s Jace’s parabatai too —”“I know about parabatai,” said Magnus, his voice rising in pitch. “I’ve known parabatai so close they were almost the same person; do you know what happens, when one of them dies, to the one that’s left—”“Stop it!” Isabelle clapped her hands over her ears, then lowered them slowly. “How dare you, Magnus Bane,” she said.“How dare you make this worse than it is —”“Isabelle.” Magnus’ hands loosened; he looked a little wide-eyed, as if his outburst had startled even him. “I am sorry. I forget, sometimes . . . that with all your self-control and strength, you possess the same vulnerability that Alec does.”“There is nothing weak about Alec,” said Isabelle.“No,” said Magnus. “To love as you choose, that takes strength. The thing is, I wanted you here for him. There are things I can’t do for him, can’t give him . . .” For a moment Magnus looked oddly vulnerable. “You have known Jace as long as he has. You can give him understanding I can’t. And he loves you.”“Of course he loves me. I’m his sister.”“Blood isn’t love,” said Magnus, and his voice was bitter. “Just ask Clary.”

“Will turned around slowly, wiping blood from his face. "You're glaring at me," he said to Magnus. "You look like Church before he bites someone.”

“He is a Shadowhunter,” said Jocelyn. “His loyalty will be to Clave and Covenant.”“He’s my friend,” said Magnus coldly. “His loyalty is to me.”

“You think she’ll be able to talk sense into him?” she asked. “His sister?”"If he listens to anyone, it would be her.”“That’s sweet,” said Maia. “That he loves his sister like that.”“Yeah,” Simon said. “It’s precious”

“The greatest fear of Jonathan is the love he feels for his sister.”

“Alec cleared his throat. He felt dizzy, but he also felt alive — blood rushing through his veins like traffic at top speed, everything seemingly almost too brightly colored. As he stepped through the door, he turned and looked at Magnus, who was watching him bemusedly. He reached forward and took hold of the front of Magnus’ t-shirt and dragged the warlock toward him. Magnus stumbled against him, and Alec kissed him, hard and fast and messy and unpracticed, but with everything he had. He pulled Magnus against him, his own hand between them, and felt Magnus’ heart stutter in his chest.He broke off the kiss, and drew back.“Friday,” he said, and let Magnus go. He backed away, down the landing, Magnus looking after him. The warlock crossed his arms over his shirt — wrinkled where Alec had grabbed it — and shook his head, grinning.”
