“I told you before, Jem, that you would not leave me," Will said, his bloody hand on the hilt of the dagger. " And you are still with me. When I breath, I will think of you, for without you I would have been dead years ago. When I wake up and when I sleep, when I lift up my hands to defend myself or when I lie down to die, you will be with me. You say we are born again. I say there is a river that divides the dead and the living. What I do know is that if we are born again, I will meet you in another life, if there is a river, you will wait on the shores for me to come to you, so we can cross together." Will took a deep breath and let go of the knife. He drew his hand back. The cut on his palm was already healing- the result of the half dozen iratzes on his skin. " You hear that, James Carstairs? We are bound, you and I, over the divide of death, down through whatever generations may come. Forever."
He rose to his feet and looked down at the knife. The knife was Jem's, the blood was his. This spot of ground, whether he could ever find it again, whether he lived to try, would be theirs.
He turned around to walk to Balios, towards Wales and Tessa. He did not look back.”
