Sorry it's taken so long, I apologise. I would like to say thank you to my loyal followers and say hello to my new followers. I hope youenjoy it, I think it might be the best chapterso far. Feel free to make your own judgement on it.

More and more bombs land under our feet and feet and after kicking them backwards and almost losing my footing several times, I decide to try to ignore them and focus on saving Tobias and Isaac.

"Left."

Luckily, each plastic box only contains a small amount of gas but there is dozens on the floor and I don't have a gas mask.

"Almost there."

So far I've been trying to hold my breath but I can't stop myself from inhaling some of the gas.

"Through here."

I can feel my heart racing faster than it's ever beaten and my migraine is worse than ever and I can feel a simulation coming on but I fight it off. I can't go into a simulation now. Another box lands a few meters infront of me but it doesn't go off

I don't see any soldiers now, perhaps they've got help up by the Dauntless and the Erudite's or maybe they've retreated.

"Last corridor." Isaac whispered with his throat hoarse.

I allow myself a small smile, I'm will see Tobias soon. The wall in my head, that I've made to keep out the aggressive simulation, cracks a little at the thought of seeing Tobias again. For a moment my headache clears.

"Tris! You shouldn't have come here."

"I had too."

"Tris. I choose to come here."

I snap myself out of the simulation to find my hand shakily pointing my gun forward.

"This is the last time I will ask you Miss Prior. Drop your weapons!" The guard in front of me.

I freeze. How did this happen? There are about thirty guard in front of me but none of the behind me, I wouldn't be able to run without them seeing me.

"I will shoot." The guard yells angrily.

I realise haven't put down my gun yet.

"Are you crazy? Put the gun down!" Gemma hisses at me.

I place it on the floor and on the way back up my migraine comes back.

"What do you mean you choose to come here?"

"Look at you, you're covered in blisters and you can't even stand up straight."

"You choose to leave?"

"Of course I did."

Tobias is wearing his jacket that was abandoned in the dessert. He couldn't have get it, I left it in Chloe's room not an hour ago.

"No you didn't."

I am held with my arms forced behind my back by two armed guards. Gemma and Isaac are held at gunpoint by Chloe and what probably is her second in command.

Chloe's gun is pointing at the back of isaac's head and her guard is pointing his gun at the side of Gemma's. She looks as tough as nails but her eyes are watering. Why have I not got a gun to my head? I deserve to have one. Chloe hates me and I've just came here to get Tobias back. Issac can't even stand up on his own, Chloe has to holds him up by scrunching his Smokers uniform in her fist.

"Let them go Chloe." I scream.

"You lead them here. I'm going to show them what happens when people decide to listen to Tris Prior.

Don't go into a simulation, you can't or she's going to shot.

"This has nothing to do with them. You-"

"It has everything to do with them."

She's going to kill them. She going to do it just to hurt me. I never wanted anyone to die because of me and it's all my fault.I should have just let them go to the hospital.

She put her finger over the trigger. I have to think of something, what does she care about? Gemma holds grabs Isaac's hand.

Tobias turns away.

"That's Tobias' friend. Tobias will hate you if you sh-"

My sentence is interrupted by a loud bang.

"Tobias could never hate me."

Isaac body slumps on the floor and Gemma pulls away from the guards grip and kneels next to him. The guard doesn't pull her back. Gemma's shaking horribly, her hands are nervously twitching as her she stoke Issac's dying body.

"You can't leave me." She whispers.

"I'm sorry." He manages to squeeze out with his last breath.

"You bitch." I wrestle again the two strong guards holding me back. I reach into my pocket and discretely put the plastic box in my hand. I can feel one of them point a gun on my head. She not going to shoot me, If she was she would have done it already.

"You're weak. Use your elbows and your knees."

I elbow the guard to left of me in the nose and turn round and knee the other in his stomach. I look at Chloe's unmasked face and throw the gas box right in front of her feet and fire at it. I take my jacket off to cover my mouth. It hisses and this time gas is red instead of blue. Chloe and her guards are stunned and don't have time to put their gas masks on. They fall to the ground and I guess they have a simulation because their bodies are very jittery. Gemma must have known what I was going to do as she has already put her gas masks on and is giving Isaac a kiss goodbye. We run out the corridor and into an empty office. Gemma slams the door shut and stuff the gap in the bottom with my jacket

"You have to go, you're going to die. You've inhaled too much gas." Gemma says forcefully.

"It's not really effecting me."

I think I finish the sentence before I'm sucked into another simulation.
