A/N: This is my ending to Allegiant. Veronica Roth owns the trilogy and the characters. When I read Allegiant, it broke my heart. This is my ending (I know a ton of people have already written their endings) but I wanted to have a try at it. Please let me know what you think! :) Only helpful and polite reviews please. My first FanFiction, so no promises on quality.

Tris

I stagger to the door, coughing and gasping, unable to catch my breath. My foot hits something -my gun-which must've fallen out of my hand when the serum was released. I do not believe I will need it, but I don't want to be surprised and not have anything to defend myself with. With gun in hand, I turn the handle and step into the dim room. As my eyes adjust to the light, I spot a small container resting on a counter to my left. The Memory Serum. I stumble towards it, but freeze as I hear a gun click behind me.

"Did you really think I wouldn't see through your act?" David wheels himself into view, his gun aimed right between my eyes. "Did you even consider," he continues, "that I might not be so trusting as my assistants? I placed extra cameras around the compound and planted a bug in your room. Good thing, too. Wouldn't want you to get away with treason." His cold eyes glint with a sort of sick pleasure as he steadies his aim. He has me at a disadvantage and I see that he knows it. He had access to all of my dauntless training, knows all of my tactics. Not to mention the element of surprise-his gun is still aimed at me and mine still points at the ground. I will have to distract him if I am to have even a ghost of a chance to succeed.

"My mother," I croak, "you loved her, didn't you?" It's cruel and I know it, but it's my best chance. He grimaces but quickly corrects himself.

"Do not think I can be so easily distracted, Girl," he growls.

"She always loved you. I don't think she ever got over you," I lie. "I discovered a secret entry from her journal. She added it later, and hid it in a way only I could figure out, I guess." David stays silent. "I know she loved my father, but I think some part of her heart always belonged to you. She loved you more, I think, but she believed it would be easiest for both of you if she let you go, so she did, out of love."

"What-what makes you think I want to hear any of this?" I can see David battling with himself, his face a give away.

"It's written all across your face." His gun is still aimed at me, his finger hovering over the trigger, but his eyes are shining with tears. I force myself to keep my eyes on him, even though I really want to run to the counter while he's hesitating. Patience. I tell myself. Keep this going, and you'll have a much better chance. David is holding the gun with shaking hands, a single tear slipping down his face.

"I-I never wanted any harm to come to her. She was just so stubborn." Now. I make a mad dash towards the counter. I hear the gun fire three times. I cry out as I feel the familiar burn of a bullet wound. I can't tell where he's hit me, but since his hands were shaking when he fired, his aim must be poor. I reach out a hand as I fall, grasping the counter and pulling myself against it. I turn and fire a shot at David, hitting the hand holding the gun. I don't want to be responsible for any more deaths. He drops his gun, but not before firing one last time. I am in agony. I reach a shaking hand out and retrieve the box. I punch in the code, releasing the serum, and fall to the ground.

I see my mother walking towards me, surrounded by a circle of light. She smiles as she kneels beside me, wrapping an arm around my shoulders so she can hold me against her.

"I missed you so much," I whisper. She tenderly brushes a strand of hair behind my ear.

"You have made me so proud, my darling. You can come with me now. I think you have suffered enough for one lifetime." I can be with my mom. I can abandon all pain, all suffering. But…what about Tobias? And Caleb. He would carry around his guilt for the rest of his life.

I remember when I was going to turn myself in to Erudite. I can clearly recall when I told Tobias that he would be okay if I died. He would find another girl, a better girl, and get over me. I still remember the look in his eyes as he told me that that was a lie. He was so earnest, so scared. I realize that I don't want to be without him either, that the pain of being without him was more than any physical pain. I don't think I can be without him; he's my other half, my better half. I can't leave him behind after everything we've been through together. We both dreamed of a future for ourselves, and I am going to try my hardest to make that dream a reality. I look at my mother, studying every detail so that I can carry the image of her in an angelic state for the rest of my life. She holds me as I black out.

A/N: Good First Chapter? I have several more on the way. I'm on Christmas break so I should be able to write a lot more.
