“You see it, don't you, James? Without Tessa there is nothing for me--no joy, no light, no life. If you loved me, you would let me have her. You can't love her as I do. No one could. If you are truly my brother, you would do this for me.”

“What do you think it would have been like if Valentine had brought you up along with me? Would you have loved me?"Clary was very glad she had put her cup down, because if she hadn't, she would have dropped it.Sebastian was looking at her not with any shyness or the sort of natural awkwardness that might be attendant on such a bizarre question, but as if she were a curious, foreign life-form."Well," she said. "You're my brother. I would have loved you. I would have...had to.”

“But he would understand,” he said dazedly. “If we explained it to him. If we told him…he would understand.”She made her voice as cold as she could. As calm. “Told him what?”Will only looked at her. There had been light in his eyes on the stairs… And it was going now, fading like the last breath of someone dying. She felt as if she were watching the life bleed out of Will Herondale. “Jem would forgive me,” Will said, but there was hopelessness in his face, his voice, already. He had given up, Tessa thought. “He would,” she said, “He would never stay angry at you, Will; he loves you too well for that. I do not even think he would hold anger toward me. But this morning he told me he thought he would die without ever loving anyone as his father loved his mother, without ever being loved like that in return. Do you want me to go down the hallway and knock on his door and take that away from him? And would you love me still, if I did?”“Then…please, Tessa, don’t tell him what I just told you…”“I will tell no one,” she said. “I swear it…”

“And broken both your hearts? How would that have benefited me? You are as dear to me as another half of my soul, Jem. I could not be happy while you were unhappy. And Tessa—she loves you. What sort of awful monster would I be, delighting in causing the two people I love the most in the world agony simply that I might have the satisfaction of knowing that if Tessa could not be mine, she could not be anybody’s?”

“You remember what else I said to you that day in the drawing room,” he said. “I want you to be happy, and him to be happy. And yet when you walk that aisle to meet him and join yourselves forever you will walk an invisible path of the shards of my heart, Tessa. I would give over my own life for either of yours. I would give over my own life for your happiness. I thought perhaps that when you told me you did not love me that my own feelings would fall away and atrophy, but they have not. They have grown every day. I love you now more desperately, this moment, than I have ever loved you before, and in an hour I will love you more than that. It is unfair to tell you this, I know, when you can do nothing about it.” He took a shuddering breath. “How you must despise me.”

“I belong to you. You could do anything you wanted with me and I would let you. You could ask anything of me and I'd break myself trying to make you happy. My heart tells me this is the best and greatest feeling I have ever had.”

“I always loved you, Will, whatever you did. And now I need you to do for me what I cannot do for myself. For you to be my eyes when I do not have them. For you to be my hands when I cannot use my own. For you to be my hear when mine is done with beating.No, said Will wildly. No, no, no. I will not be those things. Your eyes will see, your hands will feel, your hear will continue to beat.But if not, Will-If I could tear myself in half, I would-that half of me might remain with you and half follow Tessa-Half of you would be no good to either of us, said Jem.”
