“You look lousy,"Simon said.Jace blinked."Seems an odd time to start an insult contest,but if you insist,I could probably think up something good”

“You look lousy,' he said. Jace blinked. 'Seems an odd time to start an insult contest, but if you insist, I could probably think up something good.''No I mean it. You don't look good.''This is from a guy ho has all the sex appeal of a penguin. Look, I realize you may be jealous that the good Lord didn't deal you the same chiseled hand he dealt me, but that's no reason to-' 'I am not trying to insult you.' Simon snapped.”

“I think I like ‘mundane’ better than ‘bloodsucker,’” Simon muttered.“With Jace, you don’t really get to choose your insulting nickname.”-Simon and Clary, pg.234-”

“If only Simon were here. He could probably bore you to sleep.”

“If I feel the urge to burst into flames, I'll let you know," Simon was getting fed up. "Look, did you actually ask me to come all the way uptown just so you could stare at me like I'm something in a petrie dish? Next time I'll send you a photo.""And I'll frame it and put it on my nightstand," Jace said, but he didn't sound as if his heart was in the sarcasm. "Look, I asked you here for a reason, not to stare at you. Much as I hate to admit it, vampire, we have something in common.""Totally awesome hair?" Simon suggested”

“He looks," Simon had once said to Isabelle, "like he's thinking about something deep and meaningful, but if you ask him what it is, he'll punch you in the face.”

“We?" Simon looked at him in disbelief. "Are you ever going home?""What, bored with my company already?" "Let me ask you something," Simon said. "Do you find me fascinating to be around?""What was that?" Jace said. "Sorry, I think I fell asleep for a moment. Do, continue with whatever mesmerizing thing you were saying.”
