“Tris," a low voice says behind me. I don't know why it doesn't startle me. Maybe because I am becoming Dauntless, and mental readiness is something I'm supposed to develop. Maybe because his voice is low and smooth and almost soothing. Whatever the reason over my shoulder. Four stands behind me with his gun slung across his back, just like mine. "Yes?" I say. "I came to find out what you think you're doing." "I'm seeking higher ground," I say. "I don't think I'm doing anything." I see his smile in the dark. "All right. I'm coming." I pause a second. He doesn't look at me the way Will, Christina, and Al sometimes do- like I am too small and too weak to be any use, and they pity me for it. But if he insists on coming with me, it is probably because he doubts me.”
