“Yeah, well, you clearly also couldn't be bothered to call me and tell me you were shacking up with some dyed-blond wanna-be goth you probably met at Pandemonium. After I spent the past three days wondering if you were dead.""I was not shacking up," Clary said, glad of the darkness as the blood rushed to her face."And my hair is naturally blond," said Jace. "Just for the record."Simon, Clary, and Jace, pg. 115”
“Clary stopped dead in her tracks. "Simon?""Oh, God," said Jace, sounding resigned. "And here I'd actually hoped I'd got hold of something interesting." -Clary and Jace pg. 114”
“My hair is naturally blonde... Just for the record. ~ Jace”
“You look happy," he said to Clary. He swiveled his gaze to Jace. "And a good thing for you that she does."Jace raised an eyebrow. "Is this the part where you tell me that if I hurt her, you'll kill me?""No," said Simon, "If you hurt Clary, she's quite capable of killing you herself. Possibly with a variety of weapons."Jace looked pleased by the thought.”
“Jesus," said Clary."I doubt he'd fit (in the wooden box).""Jace." Clary was apalled.-Clary & Jace, pg.255-”
“I just wanted to say that it's okay if you dislike me. If you make Clary happy, I'm fine with you." He stuck his hand out, and Jace took his own hand out of Clary's and shook Simon's, a bemused look on his face."I don't dislike you," he said. "In fact, because I actually do like you, I'm going to offer you some advice.""Advice?" Simon looked wary."I see that you are working this vampire angle with some success," Jace said, indicating Isabelle and Maia with a nod of his head. "And kudos. Lots of girls love that sensitive-undead thing. But I'd drop the whole musician angle if I were you. Vampire rock stars are played out, and besides, you can't possibly be very good."Simon sighed. "I don't suppose there's any change you could reconsider the part where you didn't like me?""Enough, both of you," Clary said. "You can't be complete jerks to each other forever, you know.""Technically," said Simon, "I can."Jace made an inelegant noise; after a moment Clary realized that he was trying not to laugh, and only semi-succeeding. Simon grinned. "Got you.""Well," Clary said. "This is a beautiful moment.”
