Jessica

“I was trying to go...somewhere," Jace said. "But I kept getting pulled back here. I couldn't stop walking, couldn't stop thinking. About the first time I ever saw you, and how after that I couldn't forget you. I wanted to, but I couldn't stop myself. I forced Hodge to let me be the one who came to find you and bring you back to the Institute. And even back then, in that stupid coffee shop, when I saw you sitting on that couch with Simon, even then that felt wrong to me-I should have been the one who made you laugh like that. I couldn't get rid of that feeling. That it should have been me. And the more I knew you, the more I felt it- it had never been like that for me.”

“Simon - "You look happy. And a good thing for you that she does"

Jace - "Is this the part where you tell me if I hurt her, you'll kill me?"

Simon - "No. If you hurt Clary, she's quite capable of killing you herself. Possibly with a variety of weapons.”

“But Clary never found out what it wasn't, because there was a cry of "Jace!" and Alec appeared, breathless from pushing his way through the crowd to get them. His dark hair was a mess and there was blood on his clothes, but his eyes were bright with a mixture of relief and anger. He grabbed Jace by the front of his jacket. "What happened to you?"
Jace looked affronted. "What happened to me?"
Alec looked at him, not lightly. "You said you were going for a walk! What kind of walk takes six hours?"
"A long one?" Jace suggested.”

“I'm not going to do that."
"of course you're not." Jace said. "because you live to torture me, don't you?"
"Not everything, Jace, is about you." Clary said furiously.
"Possibly," Jace said "But you have to admit that the majority of the things are.”
