“Jem touched the parabatai rune on his shoulder, through the thin material of his nightshirt. "I am not alone," he said. "Wherever we are, we are as one.”

“Jem knotted his fingers in the material of Will's sleeve. "You are my parabatai," he said, "You said once I could ask anything of you.”

“Will closed his eyes. He could not hear Jem go, not anymore; he did not want to know the moment when he left and Will was alone, did now want to know when his first day as a Shawdowhunter without a parabatai truly began. And if the place over his heart, where his parabatai rune had been, flared up with a sudden burning pain as the door closed behind Jem, Will told himself it was only a stray ember from the fire.”

“his parabatai rune was bleeding”

“Will bit at his lip. This was the last time Jem, as Jem, might ever touch him. The sharp memory went through him like a knife—of years of Jem’s light tap on his shoulder, his hand reaching to help Will up when he fell, Jem holding him back when he was furious, Will’s own hands on Jem’s thin shoulders as Jem coughed blood into his shirt. “Listen to me. I am leaving, but I am living. I will not be gone from you entirely, Will. When you fight now, I will be still by you. When you walk in the world, I will be the light at your side, the ground steady under your feet, the force that drives the sword in your hand. We are bound, beyond the oath. The Marks did not change that. The oath did not change that. It merely gave words to something that existed already.”

“Will rose slowly to his feet. He could not believe he was doing what he was doing, but it was clear that he was, clear as the silver rim around the black of Jem’s eyes. “If there is a life after this one,” he said, “let me meet you in it, James Carstairs.”“There will be other lives.” Jem held his hand out, and for a moment, they clasped hands, as they had done during their parabatai ritual, reaching across twin rings of fire to interlace their fingers with each other. “The world is a wheel,” he said. “When we rise or fall, we do it together.”Will tightened his grip on Jem’s hand, which felt thin as twigs in his. “Well, then,” he said, through a tight throat, “since you say there will be another life for me, let us both pray I do not make as colossal a mess of it as I have this one.”
