“Isabelle," she said, lightening her tone with an obvious effort, "your loyalty to your friend is understandable --""He's not my friend." Isabelle looked over at Jace, who was staring at her in a sort of daze. "He's my brother.”

“Isabelle took out her invitation and waved it like a white flag. "I have an invitation. These"—she indicated the rest of the group with a grand wave of her arm—"are my friends."Magnus plucked the invitation out of her hand and looked at it with fastidious distaste. "I must have been drunk," he said. He threw the door open. "Come in. And try not to murder any of my guests."Jace edged into the doorway, sizing up Magnus with his eyes. "Even if one of them spills a drink on my new shoes?""Even then." Magnus's hand shot out, so fast it was barely a blur. He plucked the stele out of Jace's hand—Clary hadn't even realized he was holding it—and held it up. Jace looked faintly abashed. "As for this," Magnus said, sliding it into Jace's jeans pocket, "keep it in your pants, Shadowhunter.”

“And as for the Lightwoods," Simon said, "it's not that I like them that much. I mean, I like Isabelle, and I sort of like Alec and Jace, too. But there's this girl. And Jace is her brother."When Samuel replied, he sounded, for the first time genuinely amused. "Isn't there always a girl.”

“What did Isabelle want?" Jace asked.Alec hesitated. "Isabelle says the Queen of the Seelie Court has requested an audience with us.""Sure," said Magnus. "And Madonna wants me as a backup dancer on her next world tour."Alec looked puzzled. "Who's Madonna?""Who's the Queen of the Seelie Court?" said Clary."She is the Queen of Faerie," said Magnus. "Well, the local one, anyway."Jace put his head in his hands. "Tell Isabelle no.""But she thinks it's a good idea," Alec protested."Then tell her no twice.”

“Children of the Nephilim," Magnus said. "Well, well. I don't recall inviting you."Isabelle took out her invitation and waved it like a white flag. "I have an invitation. These"--she indicated the rest of the group with a grand wave of her arm--"are my friends."Magnus plucked the invitation out of her hand and looked at it with fastidious distaste. "I must have been drunk," he said. He threw the door open. "Come in. And try not to murder any of my guests." Jace looked at him, "Even if one of them spills something on my new shoes?" "Even then."- 219”

“I should have warned her about your habit of never doing what you're told." Jace squinted at her. "Are those Isabelle's clothes? They look ridiculous on you." "I could point out that you burned my clothes." -Jace and Clary pg. 63”
