“Jem told me what Ragnor Fell said about my father,” Will said. “That for my father, there was only ever one woman he loved, and it was her for him, or nothing. You are that for me. I love you, and I will only ever love you until I die —”

“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…”

“If Jem dies, I cannot be with Tessa,” said Will. “Because it will be as if I were waiting for him to die, or took some joy in his death, if it let me have her. And I will not be that person. I will not profit from his death. So he must live.” He lowered his arm, his sleeve bloody. “It is the only way any of this can ever mean anything. Otherwise it is only —”“Pointless, needless suffering and pain? I don’t suppose it would help if I told you that was the way life is. The good suffer, the evil flourish, and all that is mortal passes away,” Magnus said.“I want more than that,” said Will. “You made me want more than that. You showed me I was only ever cursed because I had chosen to believe myself so. You told me there was possibility, meaning. And now you would turn your back on what you created.”

“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 fell in love with you," he said, "because you were one of the bravest people I've ever known. So how could I ask you to stop being brave just because I loved you?”

“Jem--Jem is all the better part of myself. I would not expect you to understand. I owe him this.""Then what am I?" Cecily asked.Will exhaled, too exasperated to check himself. "You are my weakness.""And Tessa is your heart," she said, not angrily, but thoughtfully. "Not a fool, as I told you," she added at his startled expression. I know that you love her.”

“Then, if you love him," he said quietly, "please, Tessa, don't tell him what I just told you. Don't tell him that I love you.”
