"We shouldn’t,” protested Isabelle. “The Clave has a plan.” “The Clave has the collective intelligence of a pineapple,” said Jace. Alec blinked up at them. “Jace is right.” Isabelle turned on her brother. “What do you know? You weren’t even paying attention.” “I was,” Alec said, injured. “I said Jace was right.” “Yeah, but there’s like a 90% chance of me being right most of the time, so that’s not proof you were listening,” said Jace. “That’s just a good guess."

"You're my brother." "Those words don't mean anything where we're concerned. We aren't human. Their rules don't apply to us. Stupid laws about what DNA can be mixed with what. Hypocritical, really, considering. We're already experiments."

"So John took out of his pocket A knife both long and sharp, And stuck it through his brother's heart, And the blood came pouring down. Says John to William, "Take off thy shirt, And tear it from gore to gore, And wrap it round your bleeding heart, And the blood will pour no more."

"I do not know two finer people and could not imagine better news. May your lives together be happy and long. Congratulations, brother."

"Nicely done, brother," said Gabriel from the bed, blinking sleepy green eyes at Gideon. Gideon threw a scone at him."

"I like that stick of yours," he said. "It's a staff." Jem swung out to knock another automaton sideways. "Made by the Iron Sisters, only for Silent Brothers." [...] "Anyone can sharpen a stick." "It's a staff," Jem repeated, and saw Will's quicksilver smile out of the corner of his eye."

"I’d rather have you in my life even as a brother than not at all—"

"Being a Silent Brother is life, Clary Fray. But if you mean I remember my life before the Brotherhood, I do. Clary took a deep breath. “Were you ever in love? Before the Brotherhood? Was there ever anyone you would have died for?” There was a long silence. Then: Two people, said Brother Zachariah. There are memories that time does not erase, Clarissa. Ask your friend Magnus Bane, if you do not believe me. Forever does not make loss forgettable, only bearable."

"I'll just be your brother from now on." he said, looking at her with a hopeful expectation that she would be pleased, which made her want to scream that he was smashing her heart into pieces and he had to stop. "That's what you wanted, isn't it?" It took her a long time to answer, and when she did, her own voice sounded like an echo, coming from very far away. "Yes," she said, and she heard the rush of waves in her ears and her eyes stung as if from sand or salt spray. "That's what I wanted."
