“But that's not what you said when she walked into the room," said Simon quietly. "You said, 'Why didn't you ever tell me I had a brother?'"
"I know." Clary yanked a blade of grass out of the dirt, worrying it between her fingers. "I guess I can't help thinking that if I'd known the truth, I wouldn't have met Jace the way I did. I wouldn't have fallen in love with him."
Simon was silent for a moment. "I don't think I've ever heard you say that before."
"That I love him?" She laughed, but it sounded dreary even to her ears. "Seems useless to pretend like I don't, at this point. Maybe it doesn't matter. I probably won't ever see him again, anyway."
"He'll come back."
"Maybe."
"He'll come back," Simon said again. "For you.”

“This could be the last night of our lives, certainly the last even barely ordinary one. The last night we go to sleep and get up just as we always have. And all I could think of was that I wanted to spend it with you."
Her heart skipped a beat. "Jace-"
"I don't mean it like that," he said. "I won't touch you, not if you don't want me to. I know it's wrong - God, it's all kinds of wrong - but I just want to lie down with you and wake up with you, just once, just once ever in my life." There was desperation in his voice. "It's just this one night. In the grand scheme of things, how much can this one night matter?"
...There was nothing she had ever wanted in her life more than she wanted this night with Jace.
"Close the curtains, then, before you come to bed," she said. "I can't sleep with this much light in the room.”

“You're my sister," he said finally. "My sister, my blood, my family. I should want to protect you" - he laughed soundlessly and without any humor - "to protect you from the sort of boys who want to do with you exactly what I want to do."
Clary's breath caught. "You said you just wanted to be my brother from now on."
"I lied," he said.”

“But isn't that what love is, Clarissa? Ownership? 'I am my beloved's and my beloved is mine,' as the Song of Songs goes."
"No. And don't quote the Bible at me. I don't think you get it...It's not just that someone belongs to you, it's that you give yourself to them. I doubt you've ever given anything to anyone. Except maybe nightmares."
"To give yourself to someone?" The thin smile didn't waver. "As you've given yourself to Jonathan?"
"What?"
"You think I haven't seen the way you two look at each other? The way he says your name? You may not think I can feel, but that doesn't mean I can't see feelings in others.”
