“Before Clary could respond, Jace’s eyes slid open. He looked up at the warlock, dazzled and dizzy. “What are you doing here?”
Magnus grinned down at Jace, and his teeth sparkled like sharpened diamonds.
“Hey roommate,” he said.
-pg. 128-”

“Magnus wants to shout at me, don’t you, Magnus?” (Jace)
“Yes,” Magnus said, tearing his eyes away from Alec long enough to scowl.
-pg.275-”

“What are you doing here anyway?"
"'Here' as in your bedroom or 'here' as in the great spiritual question of our purpose here on this planet?"
-Clary & Jace, pg.306-”

“Hey," said Jace. who was sitting on an overturned speaker, looking at his cellphone, "do you want to see a photo of Alec and Magnus in Berlin?"
"Not really," said Simon.
"Magnus is wearing lederhosen."
"And yet, still no.”

“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”

“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.”

“Jace slammed his hand down on the stele. “Clary-“
“She said she doesn’t want it,” said Simon. “Ha-ha.”
“Ha-ha?” Jace looked incredulous. “That’s your comeback?”

“We have a name," said Jace. "Magnes B-"
"Shut up." Alec hissed, thwacking Jace with his closed menu. Jace looked injured.
"Jesus," he rubbed his arm. "What's your problem?”

“He has many things I haven’t got,” said Jace. “Like nearsightedness, bad posture, and an appalling lack of coordination.”
-Jace about Simon, pg. 331-”

“Cucumber and bergamot," Clary said. "Is there anything else you hate that I ought to know about?"

Jace looked at Dorothea over the rim of his teacup. "Liars," he said.”
