“He cut her off with brutal precision. "And one last thing." His eyesflicked toward the door, through which Jace, Alec, and Isabelle haddisappeared. "Keep in mind that when your mother fled from the Shadow World, it wasn't the monsters she was hiding from. Not the warlocks, the wolf-men, the Fair Folk, not even the demons themselves. It was them. It was the Shadowhunters.”
“Alec watched them through the half-open door, Jace leaned against the sink as his adoptive sister sponged his wrists and wrapped them in a white gauze. “Okay, now take off your shirt.” (Isabelle)“I knew there was something in this for you.” (Jace)~pg. 329~”
“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.”
“Isabelle drifted over, Jace a pace behind her. She was wearing a long black dress with boots and an even longer cutaway coat of soft green velvet, the color of moss. "I can't believe you did it!" she exclaimed. "How did you get Magnus to let Jace leave?""Traded him for Alec," Clary said.Isabelle looked mildly alarmed. "Not permanently?""No," said Jace. "Just for a few hours. Unless I don't come back," he added thoughtfully. "In which case, maybe he does get to keep Alec. Think of it as a lease with an option to buy."Isabelle looked dubious. "Mom and Dad won't be pleased if they find out.""That you freed a possible criminal by trading away your brother to a warlock who looks like a gay Sonic the Hedgehog and dresses like the Child Catcher from Chitty Chitty Bang Bang?" Simon inquired. "No, probably not.”
“Just because you said dragon demons were extinct—""I said mostly extinct."Alec jabbed a finger toward him."Mostly extinct," he said, his voice trembling with rage, "is NOTEXTINCT ENOUGH.""I see," said Jace. "I'll just have them change the entry in the demonology textbook from 'almost extinct' to 'not extinct enough for Alec. He prefers his monsters really, really extinct.' Will that make you happy?”
“Isabelle looked at him thoughtfully. "Did you seriously jump thirty feet out of a Malachi Configuration? Did he, Alec?""He did," Alec confirmed. "I've never seen anything like it.""I've never seen anything like this." Jace lifted a ten-inch dagger from the floor. One of Isabelle's pink brassiers was spread on the wickedly sharp tip. Isabelle snached it off, scowling.”
