REVIEW IF YOU LIKED IT. P.S I MADETHIS CHAPTER EXTRA LONG.

Two Smoker soldiers charge out of the end two buildings, with a quick turn of their heads they see me put down the speaking device and target me.

"Stop!" I shout with my gun pointed at them.

They turn so they can see each other's face and smirk, then their heads snap back and their eyes focus on to me. I see the enemy on the left side fumble with something in his pocket. It's a large vial filled with red gas. He lifts his arm in an act to throw it at me. I shoot and the gas splatters on to the ground and the red spread and floats up and chokes both of them. They cry out for help and I just stand there silently and watch. Two gunshots come from behind me and I see the bullets slam into the temples of both of their heads.

"You were just going to let them suffer in front of you?" Christina asks sounding appalled. How did she get here? Colin must have finally let her go.

"I- was saving ammo. I didn't want to w-waste it."

"You have hundreds attached to your ammo belt." I look down and realize that I slung it over my shoulder earlier, involuntary I shudder.

"That's impressive, even for you." She says coldly.

"It's sorted now, come on." She yanks my shaky arm and we run back to the crowd of waiting Dauntless.

"Here's the new plan. There will be a small group travelling with Gemma under the tunnels under the building that take you as far as the heart of building. This group will consist of Tris, Alaska, Christina, Colin, Dale, Tom, Zeke, Zoe, Shauna and Derek. At the same time the rest of us will be a distraction from this group by fighting out way through the building through different entrances in the building. We will get control and then get the cure and find Tobias. One thing to remember, if you hear this screech," he presses a button on a tiny control pad and a huge screech fills the air projecting from that pad and with a few shouts from the older people on the crowd he turns it off.

"If you hear that, I want everyone to leave immediately. I don't want to press it but if needs must, I will. You better run too, we won't wait around."

"We are smart and we are brave. We can do this." He shouts.

He turns and everyone follows him except for our group as we don't know where we are heading yet.

"We have to head west until we find this huge drain. That will lead us to the tunnels." We start walking quickly, searching the ground for the metal opening.

"Is it part of the sewage system?" Shauna asks.

"No. It's an old emergency tunnel, it was built when the old purity war started to protect the children. Nobody uses it as it has been blocked for years."

"How are we supposed to get through it if it is blocked?" I ask desperately.

"I snuck out that way. Unfortunately, Chloe and her guards were on a patrol and caught me crawling out of it." Chloe says sharply.

"We have to hurry up. We can't expect them to 'distract' The Smokers all day." Plus Tobias could be dying now. If I could've saved him but I was too late because I was too busy chatting in the desert, I won't be able to forgive myself.

I start running and the rest try to keep up. I pretend not to notice Alaska weak red face as I knew if I looked too long, I would slow down my pace so she could keep up. After a few minutes of quiet with only my racing heartbeat and the stomp of our feet hitting the dry dirt to provide sound, Zoe's shout gives me a headache.

"It's over here." I follow her finger and sprint towards it. I let Gemma go in front as she knows the way but I slip into the open latch behind her. I want to protect the rest of my group as well as Tobias. When we reach up to the ground level, there will be soldiers buzzing through the corridors and I will be in front ready to kill them before they can kill my friends.

There's just enough room for me to walk almost normally, with my head slightly tilting down and for us two walk with a person by our side. The others have to crouch down as they are all taller than me. Luckily, Gemma remembered to bring flash lights and we pass it down, so everyone can have one. I switch mine on and I pass Derek the last torch. I finally get a good look at him. He's got wavy brown hair and his nose is pierced and his ear is stretched. He has got little fragments of black shards that are shattered around the left of his face. I examine all of them quizzically, they are all different sizes but are arranged perfectly together. I wonder how long it took him to get it tattooed. I just realised that I've looked at him for way too long.

"I know my face is beautiful, you're more that welcome to stare at it all day."

I blush and look away, "I was looking at your tattoo."

"I know. I'm sorry, I know you love Tobias. I'm just messing around. I want to make a girl smile one last time."

"I may not be able to help you. I'm not in a smiling mood."

"If not, I'm sure I can picture it in my mind."

I don't know what to day back so we keep walking and every few minutes we have to go crouch through an opening in a wall of rocks and then the tunnel goes back to the normal size.

"We should be near the end now."

Gemma comes to a sharp holt.

"It's blocked."

Stone are piled on top of each other from the floor to the roof.

"We need to get the ones at the top down first or else the whole thing will fall and crush us." Derek says morbidly.

"Let's get started then." Christina shouts.

Derek carefully heaves a rock out of its formation and passes it down to Zeke and he puts it on the side of the tunnel.

I and Dale help get the rocks down too. With each rock being pulled, the more chance the whole thing will collapse. After several minutes of this I start to feel faint. There isn't enough oxygen down here and even this is tiring me out.

"We can squeeze through now." Gemma says.

There a whole at the right side of the wall, it's small but I could fit through it. Gemma stares at it worriedly. "You want me to go through it first?"

She nods and I step towards it.

"Move back, just in case I knock a rock."
I squeeze my head through the whole and turn side wards. My shoulders scrape the rocks and if I didn't have Tobias' jumper on, it would have grazed all my arms. My hips slide through a little easier. I put my hand on the tunnels ground for stability and pull my feet through the gap. I look expectantly at the rock and expect it to fall over but it remains still.

"Next." I shout.

"Make sure you still stay back guys." She says.

She quickly pushes her way through and it miraculously it doesn't budge.

"Come on, Dale." Gemma says encouragingly.

"He's a bit nervous." She whispers in my ear.

I push Gemma back a few meters as I know he is quite tall, muscular man.

I see his head pop through to my side of the wall. He tries to put his shoulder through the gap but It isn't wide enough. He tries to push the rocks to expand the whole so he can fit through. The rocks move slightly forward but he hasn't noticed it. He pushes again. They crash down and he's in the middle of all of them.
