“Something inside Clary cracked and broke, and words came pouring out. ‘What do you want me to tell you? The truth? The truth is that I love Simon like I should love you, and I wish he was my brother and you weren’t, but I can’t do anything about that and neither can you!” - City of Ashes
“I love you Clary. More then I ever— God. More than i probably should. You know that, don’t you?” - City of Fallen Angels
“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.”

“His hands lay flat on either side of him, his arms at his sides. He seemed barely to be breathing; she wasn’t sure she was breathing herself. She slid her own hand across the bedsheet, just far enough that their fingers touched-so lightly that she would have probably hardly been aware of it had she been touching anyone but Jace; as it was, the nerve endings in her fingertips pricked softly, as if she were holding them over a low flame. She felt him tense beside her and then relax. He had shut his eyes, and his lashes cast fine shadows against the curve of his cheekbones. His mouth curled into a smile as if he sensed her watching him, and she wondered how he would look in the morning, with his hair messed and sleep circles under his eyes. Despite everything, the thought gave her a jolt of happiness.
She laced her fingers through his. “Good night,” she whispered. With their hands clasped like children in a fairy tale, she fell asleep beside him in the dark.” - City of Glass
