“Well, I hate to tell you this," she said, "but your friend is an asshole."
"He's not my friend," said Simon. "And I couldn't agree with you more, actually."
-Maia & Simon about Jace, pg.49-”

“Well, I’m not kissing the mundane," said Jace. "I’d rather stay down here and rot."
"Forever?" said Simon. "Forever’s an awfully long time."
Jace raised his eyebrows. "I knew it," he said. "You want to kiss me, don’t you?”

“Well, you know, your mom gets like this sometimes," Simon said. "Like when she breathes in or out.”

“Isabelle snorted, "All the boysgay. In this truck, anyway. Well, not you, Simon."
"You noticed," said Simon.
"I think of myself as a freewheeling bisexual," added Magnus.
"Please never say those words in front of my parents," said Alec.”

“You snuck up on me,” she said. “I guess I’m not much of a Shadowhunter, huh?”
Simon shrugged. “Well, in your defense, I do move with a silent, pantherlike grace.”

“Goddamn it,” Jace shouted over the noise. “I hate it when Simon is right.”

“I said to a guy, I said, "Tell me, what is it about cocaine that makes it so wonderful?", and he said, "Well, it intensifies your personality." I said, "Yes, but what if you're an asshole?"”

“Why do you tell me you love me only when you're drunk or dreaming? she asked. I have awful timing, said Simon”

“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.”

“I'm Magnus." He smiled, showing blinding white teeth.
"Magnus Bane."
"Are we long-lost friends, by any chance?" Simon said.
"Just wondering."
"No, we never got along all that well," said Magnus.
"Long-lost acquaintances? Compadres? My cat liked you.”
