I have to do something, I tell myself. I sprint to the Bureau as fast as I can. They call for me to come back but I can't. Then, I will be too late to save her. Maybe I already am. I push the door open and run down the halls. I pass a gun, maybe Tris's and pick it up. I continue running to the Weapons Lab. I stop. All the thoughts overwhelm me. Tris may be dead, or she may have forgotten who I am. I take a deep breath and step inside. The serums should have worn off by now. In the weapons lab, I find not Tris, but David sitting in his wheelchair. It stings my heart to look at him. "What do you think you did?" I yell at him. I don't even try to say it, it just comes out. "My girlfriend is going to die because of you! Tris is going to die!" As I say those words my body aches all over. Right now, I am way more sad than I am mad. It just doesn't seem right. I can't think about it. I cannot imagine a world without her. He just sits there and stares at me with a confused look which makes me both more sad and mad.
"I don't recall recently killing everyone," he says. He still has that annoying tone to his voice. "Anyways, who is Tris?" He doesn't know anything anymore. An innocent. Except he will never be an innocent to me. I can't live with him. So I pick up the gun and I aim.
"Stop!" a familiar voice shouts. Caleb. "Don't do it!"
"Caleb, what are you doing here?" I ask. The last thing I want right now, is her brother, the one that was supposed to do this, with me. It brings back the aching feeling.
"I...just...want to see...my sister," he says. He is sobbing and he barely manages to choke out those words. "But...there has to be another...way. You don't...have to...shoot." He doesn't understand. He doesn't know what it's like to love someone, like I love Tris, and then lose them. It's like the world is ending. And he wouldn't know what that feels like and he never will. So I Put the gun back in position and fire. "Stop!" Caleb yells again but it's useless. It is too late. David lies there on the floor, his wheelchair tipped over. I thought this would make me feel better, but it doesn't. It makes me feel worse, knowing I had to do this, because of what he did. All those times she made it. I don't think this time. I'm barely keeping myself together. I hear Caleb's footsteps in the opposite direction. I don't want to look but I have to. I manage to move my head far enough to see her. Tris.
