"What's this?" he demanded, looking from Clary to his companions, as if they might know what she was doing there.
"It's a girl," Jace said,recovering his composure. "Surely you've seen girls before, Alec. Your sister Isabelle is one."

"Don't." Clary raised a warning hand. "I'm not really in the mood right now."
"That's got to be the first time a girl's ever said that to me," Jace mused.

"Out of the corner of her eye she thought she saw Jace shoot her a look of white rage - but when she glanced at him, he looked as he always did: easy, confident, slightly bored.
"In future, Clarissa," he said, "it might be wise to mention that you already have a man in your bed, to avoid such tedious situations."
"You invited him into bed?" Simon demanded, looking shaken.
"Ridiculous, isn't it?" said Jace. "We would never have all fit."
"I didn't invite him into bed," Clary snapped. "We were just kissing."
"Just kissing?" Jace's tone mocked her with its false hurt. "How swiftly you dismiss our love.

He cut his glance toward Jace, who was walking a few paces ahead of them, apparently conversing with the cat. Clary wondered what they were talking about. Politics? Opera? The high price of tuna?

"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."

"You're just worried they'll hire a male instructor and he'll be hotter than you."
Jace's eyebrows went up. "Hotter than me?"
"It could happen," Clary said, "You know, theoretically."
"Theoretically the planet could suddenly crack in half, leaving me on one side and you on the other, forever and tragically parted, but I'm not worried about that either. Some things," Jace said, with his customary crooked smile, "are just too unlikely to dwell upon."

Jace was still staring at her as if she'd told him she'd found out one of the Silent Brothers doing nude cartwheels in the hallway.

"It's not gray," Clary felt compelled to point out. "It's green."
"If there was such a thing as terminal literalism, you'd have died in childhood," said Jace.

Even in half demon hunter clothes, Clary thought, he looked like the kind of boy who'd come over your house to pick you up for a date and be polite to your parents and nice to your pets.
Jace on the other hand, looked like the kind of boy who'd come over your house and burn it down just for kicks.

"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?"

It's a girl," Jace said, recovering his composure. "Surely you've seen girls before, Alec. Your sister Isabelle is one.

"Clary felt suddenly annoyed. "When the self-congratulatory part of the evening is over, maybe we could get back to saving my best friend from being exsanguinated to death?"
"Exsanguinated," said Jace, impressed. "That's a big word."
"And you're a big-"
"Tsk tsk," he interupted. "No swearing in church.

Yeah, well, you clearly also couldn't be bothered to call me and tell me you were shacking up with some dyed-blond wanna-be goth you probably met at Pandemonium. After I spent the past three days wondering if you were dead."
"I was not shacking up," Clary said, glad of the darkness as the blood rushed to her face.
"And my hair is naturally blond," said Jace. "Just for the record.

I forgot that's what gets you all hot and bothered, Jace. Girls killing things."
"I like anyone killing things," He said equably, "Especially me.
