"Fernando crouches next to one of the beds and takes out a box. He digs inside it for a few seconds, then picks up a small, round disc. It is made of a pale metal that I saw often in Erudite headquarters but have never seen anywhere else. He carries it toward me on his palm. When I reach for it, he jerks it away from me. "Careful!" he says. "I brought this from headquarters. It's not something we invented here. Were you there when they attacked Candor?" "Yes," I say. " there." "Remember when the glass shattered?" "Were there?" I say, narrowing my eyes. "No. They recorded it and showed the footage at Erudite headquarters," he says. "Well, it looked like the glass shattered because they shot at it, but that's not really true. One of the Dauntless soldiers tossed one of near the widows. It emits a signal that you can't hear, but that will cause glass to shatter." "Okay," I say. "And how will that be useful to us?" "You may find that it's rather distracting for people when all their windows shatter at once," he says with a small smile. "Especially in Erudite headquarters, where there are a lot of windows." "Right," I say. "What else have you got?" says Christina. "The Amity will like this," Cara says. "Where is it? Ah. Here." She picks up a black box made of plastic, small enough for her to wrap her fingers around it. At the top of the box are two pieces of metal that look like teeth. She flips a switch at the bottom of the box, and a thread of blue light stretches across the gap between the teeth. "Fernando," says Cara. "Want to demonstrate?" "Are you joking?" he says, his eyes wide. "I'm never doing that again. You're dangerous with that thing." Cara grins at him, and explains, "If I touched you with this stunner right now, it would be extremely painful, and then it would disable you. Fernando found that out the hard way yesterday. I made it so that the Amity would have a way of defending themselves without shooting anyone." "That's..." I frown. "Understanding of you." "Well, technology is supposed to make life better," she says. "No matter what you believe, there's a technology out there for you." What did my mother say, in that simulation? "I worry that your father's blustering about Erudite has been to your detriment." What if she was right, even if she was just a part of a simulation? My father taught me to see Erudite a particular way. He never taught me that they made no judgments about what people believed, but designed things for them within the confines of those beliefs. He never told me that they could be funny, or that they could critique their own faction from the inside. Cara lunges toward Fernando with the stunner, laughing when he jumps back. He never told me that an Erudite could offer to help me even after I killed her brother."
