To Tobias, his life is Hell. Known as the one who won't stop till he's dead, he's helping free prisoners during World War 2. However, something in him changes when he meets a very confused girl with secret. AU.

The cannons overhead are deafening.

The whole bloody world is at war now, blames and bullets now as common as your usual market sales. For once, I'm thankful that I'm underground so the screams of the dying and the shots from their muskets are muffled. Down underground isn't much better either, but at least I'm on my own independent task. Don't know if that's a good thing or bad thing, you see, because I killed my general. Eric wasn't one for competition; he was self absorbed, murderous, and an arrogant bastard. God, if he's all those things, where does that put me?

But I don't really care about him right now. Inside the cells where they keep the prisoners, dozens of our best are kept in these infernal places. Already, the door to Christina's cell clicks open as if slam the lock with the back of my gun. Falling to the floor with a loud clang, the lock shatters as if it where made of glass. She stumbles out, wiping her face with a dirty palm before giving me a nod of gratitude.

"Get a move on, sergeant." I bark, tossing her a loaded musket from my bag. "They've been getting the upper hand. We need as many of you out there as possible." Grabbing it as it falls to the ground, she raises an eyebrow.

"How are we supposed to fight with this few soldiers?"

"There are others. Turn left down the tunnel and you'll see them. Unlock them as well." I order, shoving a few other guns into her hand. Without waiting to hear her response, I jog down the tunnel and position myself in front of another cell. By the sound of the pained groans and the flash of brown hair against his bronze skin, I could tell it was Uriah.

I repeat the procedure on this cell, smashing the lock and letting the door creak open, but only this time, no one comes out. Peering in, Uriah's on the floor, his shoulder caked in blood. Without me having to take a second glance, I know he's been shot.

"Four, God damn it." He grits between his teeth, his fingers digging into his shoulder. "It hurts, like, a lot."

"No shit." I scoff, looking at him in incredulousness. He holds out a hand, and I almost take it.

Almost.

But I don't.

"Sorry Uriah." I say reluctantly. I can't waste supplies on him. I already know he's going to die. "I can't take you. It's too risky." I start to turn around when Uriah lets out a small choking cry.

"Four? After all we've done together, you just give up? It's just my shoulder, I can keep up." He lets out a small whimper, the wound in his shoulder opening up as he strains to stand. "Remember when I helped you? Your father, Eric, everyone?"

"That was in the past. I'm not the coward that everyone thought I was."

"Four-"

"Shut up." Turning my back on Uriah, I shut his door, blocking out the sound of him throwing his bloodied hands against the rusted metal. Then I fix my thumb on the trigger of my musket and walk away.

I arrive at the last door, expecting to see more of my comrades inside the cell, but all I can see is a flash of blond hair. When I manage to pry the door open, I can see a girl inside. God, she look young. We all are, but she's still got the face of a child, which is twisted in fear. For some reason, she doesn't look at me. In fact, her eyes are still glued to the wall, her knees pulled to her chest. As if noticing me for the first time, she turns my direction and just stares.

The first thing I notice are her eyes; they're an enormous milky gray and blue, startlingly bright against the dark and dank conditions of the cell. Her dark blond hair, which is cut in choppily at her chin, is stained with blood. I feel like I've seen her before. Possible in Uriah's army? No, I would know his soldiers. Christina's? Unlikely. Will's? Possible. However, unlike many of the soldiers in our army, her black leather jacket is laced with gray cotton, forming an intricate pattern on her sleeve. Despite having the same leather clad boots and skin tight black pants, she has an innocence in her expression that hardly looks like one of a fighter.

"Caleb?" She says finally, still staring at me blankly. She moves her hand forward, grasping at the cold rock beneath her feet. "Caleb? Is that you?"

"Halt." I order, my hand tightening on my musket. Immediately realizing that I wasn't 'Caleb', whoever he is, she shrank back to the wall, frowning. "Who are you, soldier?"

"Soldier?"

"What army are you from?"

"I'm not from an army."

She's not from an army? What is she? An escapee from a town? Perhaps she pillaged through the battlefield like all the others, looking for new supplies. "Why are in here? Are you a prisoner?"

"Yes. I was visiting my brother whose in the Erudite army. There were others waiting. They started shooting and dragging us through tunnels, I think, then they started asking him for questions and he was screaming and there was there were loud shouts and then-" She breaks off, rocking back and forth, her hands on the sides of her head. Drawing in a sharp breath, her chest shakes as if she has trouble breathing. "I don't understand."

"Those Erudites." I snarl, not meaning too. The Dauntless army, though we are 'allies', have never cared for the Erudite with all their smart-aleck ways and their over complicated tactics.

"You're one of them, aren't you?" She whimpers, trying to push herself as close into the corner as she possible can. She looks so small and so weak in her cell that I can't help but feel a small bit of pity.

"I'm not an Erudite. I'm from the Dauntless army."

"Dauntless?"As I near her, that bit of weakness that I thought she had disappeared and is replaced by defensiveness. Lashing out near my face, her face twists into a scowl. "Don't touch me."

"I'm not going to hurt you." Am I?

"That's what they all say. How do I know I can trust you too?" She spits savagely, her hair veiled over her face. Her hands fumble over the ground where she picks up a moderately sized rock and holds it close to her. Apparently to her, her rock beats my gun. Is she stupid or what? And then, when she goes to look up at me again and seemingly stares off into space, I realize she's blind.

"You're blind, aren't you?"

Biting her lip hesitantly, she nods. A small sob in the back of her throat echoes through the cell, her hands still clenched feverishly around the stone. She presses her eyes closed, tears leaking out of the creases at the edges of her eyes. "I just wanted to find my brother. He's dead, isn't he."

And then I do something that I haven't done since Christina lost her sister. I drop to my knees and put my hands on her shoulders. "It's going to be alright. I'll get you out of here, okay?" I say, trying to comfort her growing cries. "We'll find your brother." I add, though I know that, in these conditions, he's probably dead. Either way, I need to get her to trust me. The innocence that radiates off of her makes me feel softer and I think that maybe, if I save her, I'll have retained a bit of my humanity.

"Promise?" She opens her eyes and I can see myself staring back at me. They're like clouds and, in the midst of the battle, seem so pure and whole. Dropping my gun on the ground, I guide her arms around my neck.

"I promise..?"

"Tris."

"I promise Tris."

"Okay...?

"Four...No, Tobias."

"Okay Tobias." It seems so mundane to be trading names, but in that moment, it doesn't really matter. Using all my strength, I heave her off the floor before realizing how light she is. I should have guessed. She's as light as a bird with the same racing heart, her arms still over my shoulder and around my neck. Then, despite everything, a small smile graces her lips and her sobs fall silent.

And in that moment, I can't help but love her.
