"You guessed? You must have been pretty sure, considering you could have killed me."
"I was ninety percent sure."
"I see," Clary said. There must have been something in her voice, because he turned to look at her. Her hand cracked across his face, a slap that rocked him back on his heels. He put his hands on his cheek, more in surprise than pain.
"What the hell was that for?"
"The other ten percent."

Duncan spoke quietly: 'Lucilla, if you touch me again without my permission, I will <i>try</i> to kill you. I will try so hard that you very likely will have to kill me.

"No. That's Clary; shes's my best friend." Simon pocketed his phone. "And she has a boyfriend. Like, really, really, really has a boyfriend. The nuclear bomb of boyfriends. Trust me on this one."

I will kill you if you set me free,' the eyes said. 'Set me free.

here she is, all mine, trying her best to give me all she can. How could I ever hurt her? But I didn’t understand then. That I could hurt somebody so badly she would never recover. That a person can, just by living, damage another human being beyond repair.

If anything might hurt her, silence would; and I wanted to hurt her.

"Sometimes they threaten you with something - something you can't stand up to, can't even think about. And then you say, "Don't do it to me, do it to somebody else, do it to So-and-so." And perhaps you might pretend, afterwards, that it was only a trick and that you just said it to make them stop and didn't mean it. But that isn't true. At the time when it happens you do mean it. You think there's no other way of saving yourself, and you're quite ready to save yourself that way. You WANT it to happen to the other person. You don't give a damn what they suffer. All you care is yourself."

"Don't touch any of my weapons without my permission."
"Well, there goes my plan for selling them all on eBay," Clary muttered.
"Selling them on what?"
Clary smiled blandly at him. "A mythical place of great magical power."

"Knowing those things are going to kill you," she said, "and still you do it."
"How differently I might behave," Tom said, "if immortality were an option."

"I don't care," Clary said. "He'd do it for me. Tell me he wouldn't. If I were missing-"
"He'd burn the whole world down till he could dig you out of the ashes. I know," Alec said.

"Jace?"
"Yeah?"
"How did you know I had Shadowhunter blood? Was there some way you could tell?"
The elevator arrived with a final groan. Jace unlatched the gate and slid it open. The inside reminded Clary of a birdcage, all black metal and decorative bits of gilt. "I guessed," he said, latching the door behind them. "It seemed like the most likely explanation."
"You guessed? You must have been pretty sure, considering you could have killed me."
He pressed a button in the wall, and the elevator lurched into action with a vibrating groan that she felt all through the bones in her feet. "I was ninety percent sure."
"I see," Clary said.
There must have been something in her voice, because he turned to look at her. Her hand cracked across his face, a slap that rocked him back on his heels. He put a hand to his cheek, more in surprise than pain. "What the hell was that for?"
The other ten percent," she said, and they rode the rest of the way down to the street in silence."

"Is there some particular reason that you're here?" ...
"Not this again."
"Not what again?" said Clary.
"Every time I annoy him, he retreats into his No Mundanes Allowed tree house." Simon pointed at Jace.

"It seems somewhat illogical to say, "You have violated God's commandment 'Thou shalt not kill,' so therefore I will kill you.

"Don't tell me," Jace said, "Simon's turned himself into an ocelot and you want me to do something about it before Isabelle makes him into a stole. Well, you'll have have to wait till tomorrow. I'm out of commission." He pointed at himself - he was wearing blue pajamas with a hole in the sleeve. "Look. Jammies."
"Jace," Clary said, "this is important."
"Don't tell me," he said. "You've got a drawing emergency. You need a nude model. Well, I'm not in the mood. You could always ask Hodge," he said as an afterthought. "I hear he'll do anything for a -"
"JACE!" she interrupted him, her voice rising to a scream. "JUST SHUT UP FOR A SECOND AND LISTEN, WILL YOU?"
