An: Thank you all for following and reviewing this story!

We finish the fights for today. Everyone, especially my friends look at me in amazement but also concern. They all know that I have been gassed, I've convinced most that it doesn't affect you that much but everybody knows it makes you weaker. I can tell they are going to want to speak to me. "Train?" Tobias asks the others, we all don't like speaking about private thing in Dauntless, and we all know they like to watch us from the camera dotted around places. There isn't so many now, most are destroyed but it doesn't help us from being paranoid.

"Let's go."

We all run to the train, Tobias and I run in front. Luckily, we don't have to wait, we trains already arriving. I sprint faster, managing to get a head start on the train.

"Three!" I yell loudly before I jump onto the third carriage. I hit the stone floor and manage to push myself in the corner before Tobias almost lands on me. He is about to apologize but I give him a quick kiss on the cheek and walk to the edge of the doorway just in case they need help. They probably won't. There is a lot of blurred clothing and all of a sudden everyone jumps in, only a couple seconds after each other. Most are not hurt but Tom fell on top of Zoe. She laughs of the pain and shoves him off.

"Revenge?" Tom asks.

She punch him in the arm and they both laugh and share a kiss. I can feel myself smiling, it might be a strange relationship but I know they love each other dearly. All of us sit down, couples together and Alaska and Dale sat comfortably together.

"Thanks for getting me out of fighting today, I would have died." Alaska says.

"How did you manage to fight Charles, Tris?" Christina asks.

"I though the gas make you weaker?" Colin says.

"That would've been a challenge, even for me. You couldn't even walk earlier." Tobias says.

"I don't know how I did it. I just got angry." I shrug.

I don't know what they want me to say, I don't know what happened.

"I think your resisting the gas, your body is somehow fighting it." Shauna says.

"You're lucky, I'm getting weaker." Alaska says angrily.

She must be jealous of me. I would change places with her in an instant, I really would but it doesn't work like that.

"You've been gassed too?" Zeke asks.

She nods sadly in answer. Everyone looks at her, trying to show sympathy through their facial expressions.

She just told everyone her secret.

"I'm sorry." Dale says, tears visible in his eyes.

"It's not your problem it's mine, so stop staring." She gets up and jumps off the train, which has luckily slowed down because "Alaska!" I shout even though I know she can't possibly hear me.

Dale rushes to the door and jumps with full strength. I jump up from the floor. Tobias grabs my sleeve and we jump out to together. We left just in time to jump onto the edge of the Erudites train platform. I landed on my knees and hands, Tobias helps me up and we start running forward hoping to find Alaska. I spot Dale rushing up the Erudites stairs, Alaska just in front. We manage to catch up with them and they finally slow down.

"Alaska!" Dale shouts.

She turns around and her face is red and she's breathing heavily. Every few seconds her face twitches. "It's happening again and I can't stop it."

"Alaska listen to me. You are stronger than this. You can fight it, you just have to overpower it." I shout.

She squeezes her head so hard I wonder if she's trying to crush it. Dale edges closer nervously, wary of her mental state. She sways side to side and I leap forward. Dale manages to catch her before she falls completely. Her eyes shut and everything start twitching and fitting but Dale still lets her lie on his lap. Tobias walks up to the Erudites entrance, "How can you be sure the gas isn't lingering inside the building?" I ask.

"I'll find some medicine or something to help. Stay with her and don't follow me." He demands but Dales is fixated with Alaska.

It would be pointless to say hurry up or we don't have much time because he's determined and hates death as much as I do.

I place my fist on my heart and he does the same. We used to do that all the time before we had to do something dangerous without the other and there wasn't enough time to speak. It makes me feel braver and every time my heart beats I know he'll be safe.

Alaska's still convulsing badly. I try to hold down her limbs but it only makes it more violent, so we release them. Dale hopelessly tries to get her to stop, shouting and screaming her name. She starts screaming in agony and continues to whack us with her limbs. This carries on for a couple of minutes. Tobias jumps down next to us with a needle filled with a green liquid. It seems impossible to get her to stop moving so he can insert it. Dale's back covers her damaged body in protection.

"I don't want you to hurt her." He spits angrily.

Knowing it will take longer to explain, Tobias yanks her body from him. He dives for Tobias but I tackle him and push him out of the way. He's angry, he doesn't understand that we are trying to help her. Her screams stop and I peaceful quiet fills the air for a moment.

"We have sedated her. Whatever's going inside her brain has stopped for a while. She's fine." Tobias says carefully.

"I thought you were going to kill…" he mumbles.
