“I thought you hated demons. Now you use them like servants. The Ravener, the Drevak demons, Agramon-they‘re your employees. Guards, butler-personal chef, for all I know.”-Jace to Valentine, pg.260-”

“Just take the weapon you hold in your hand and drive it through his heart," Valentine's voice was soft. "One simple motion. Nothing you haven't done before."Jace met his father's stare with a level gaze. "I saw Agramon," he said. "It had your face.""You saw Agramon?" The Soul-Sword glittered as Valentine moved toward his son. "And you lived?""I killed it.""You killed the Demon of Fear, but you won't kill a single vampire, not even at my order?"Jace stood watching Valentine without expression. "He's a vampire, that's true," he said. "But his name is Simon.”

“You know what I am." The words breathed out in an auguished whisper. "I'm part demon, Clary. Part demon. You understood that much, didn't you?" His eyes bored into her like drills. "You saw what Valentine was trying to do. He used demon blood-used it on me before I was even born. I'm part monster. Part everthing I've tried so hard to burn out, to destroy.”

“Jace: "I guess we better move the trash. We can start with the Dumpster," looking unenthusiastic.Clary: "You'd rather face a ravening horde of demons, wouldn't you?"Jace: "At least they wouldn't be crawling with maggots. Well, not most of them, anyway. There was this one demon, once, that I tracked down to the sewers under Grand Central--"Clary: "Don't. I'm not really in the mood right now."Jace: "That's got to be the first time a girl's ever said that to me."Clary: "Stick with me and it won't be the last.”

“First, the candy and flowers, then the apology letters, then the ravenous demon hordes. In that order." -Jace Wayland”

“It wouldn't be my move," Jace agreed. "First the candy and flowers, then the apology letters, then the ravenous demon hordes. In that order.”
