“He had become a monster. You just couldn't see it...because it wore the face of a friend.”

“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?”

“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?”

“Well, I hate to tell you this," she said, "but your friend is an asshole.""He's not my friend," said Simon. "And I couldn't agree with you more, actually."-Maia & Simon about Jace, pg.49-”

“And then we met you, and it was like he woke up. You couldn't see it, because you'd never known him any different. But I saw it. Hodge saw it. Alec saw it -why do you think he hated you so much? It was like that form the second we met you. You thought it was amazing that you could see us, and it was, but what was amazing to me was that Jace could see you too.”

“Samuel! Are you alright?" A vision of Samuel being brained by the falling bars rose up before Simon's eyes. Samuel's voice rose to a scream. "GO AWAY!" Simon looked sideways at Jace. "I think he means it." 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?”

“You have a dark heart in you, Valentine’s daughter,” he said. “You just won’t admit it. And if you want Jace, you had better accept it. Because he belongs to me now.”
