I see the Abnegation sector of the city. Why here? My mind flutters with ideas. Erudite made the serum they injected us with. Of course! They want the most powerful faction to destroy Abnegation because of their rivalry. The trains stops abruptly. Everyone jumped out and began to bombard people reaching into mailboxes. Soon, dead bodies littered yards.

Eric strides over to me and Tobias, who is staring ahead at mere nothingness. "Would anyone notice if the mighty Four died?" he grins. Eric's partner said as if bored " Go ahead." Eric skillfully flipped his gun out of the holster and pressed it to Tobias's head. " Just in case you are Divergent," Eric says."Let's do some math." Even though he is behind me, I can hear him fighting not to laugh. " If you had 10 cakes," Eric began." and someone took 2 cakes, how many would you have?" Tobias remains silent. "Okay, lets put it this way. If someone forcefully takes 2 of your 10 cakes, how many would you have?" Tobias says happily "10 and a dead body." I turn and aim my gun at Eric, who laughs. "Oh Tris, you won't shoot me." I smile and lower my aim to his foot, and fire.

Me and Tobias run.
