"I forgot that's what gets you all hot and bothered, Jace, girls killing things."
"I like anyone killing things, especially me." he said with a smile.

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.

"They can't be worse than vampires. And you did all right with them."
"Did all right with them? By which I take it you mean we survived?"
"Well. . ."
"Faeries," Jace went on, as if Simon hadn't spoken, "are the offspring of demons and angels, with the beauty of angels and the viciousness of demons. A vampire might attack you, if you enter its domain, but a faerie could make you dance until you died with your legs ground into stumps, trick you into a midnight swim and drag you screaming underwater until your lungs burst, fill your eyes with faerie dust until you gouged them out at the roots-"
"Jace!" Clary snapped.

"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.

I didn't," said Jace. "At least, I didn't finish it. It's Magnus Bane." He grinned at Alec mockingly. "Rhymes with 'overcareful pain in the ass.'

"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.

No offense to anyone involved, but the only one among you who seems formidable is Jace. An untrained Shadowhunter and a scared vampire. . .

"Jace shook his blond head in exasperation.
"You had to make a crazy jail friend, didn't you? You couldn't just count ceiling tiles or tame a pet mouse like normal prisoners do?

"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."

Simon was looking at Jace as if he were both fascinating and also a little alarming. 'Did I-- did we ever-- did I bite you?' Jace touched the scar on his throat. 'I can't believe you remember that.' 'Did we... roll around on the bottom of a boat?' 'Yes, you bit me, yes, I kind of liked it, yes, let's not talk about it again,' said Jace.

"Can I help you with something?"
Clary turned instant traitor against her gender. "Those girls on the other side of the car are staring at you."
Jace assumed an air of mellow gratification. "Of course they are," he said, "I am stunningly attractive."
