A/N: I can't thank you enough for sticking with me through this story. I appreciate every single favourite, follow and review. When I first started writing this, I didn't think for one moment that I would almost reach 100 reviews. Thank you so much!

I'm unsure of what to do at this point. I've been writing this story for almost a year now, and my writing style has changed and improved so much since. I feel like the work I can put into this story is limited. I may just end the story here. I'm undecided as of now. Please leave a review and let me know what you think.

Four's POV

I stand on the platform as I wait for the train to arrive. Night has already fallen, and the moon provides only little illumination. The wind whistles between distorted trunks and eyes glimmer from tree hallows. The only sound is my heart beating rapidly in my chest, so loud I'm sure everyone can hear it.

I take a deep breath as the train rounds the corner, it's lights blaring ahead, lighting up the platform just enough for me to see where I'm going. I start jogging ahead as I wait for the train. When it grows nearer, my jog turns into a sprint. I press the button to open the door of the last compartment and haul myself inside.

I slump against the wall of the compartment and rest my chin on my knees. I'd transferred to Dauntless for two reasons: The first being to escape Marcus, and the second for a fresh start.

But Tris knows who you really are.

"Tobias..."

I jerk upright, my eyes darting in the direction the voice had come from. There she stands, wearing a low collared black t-shirt to show the three ravens imprinted on her collarbone and tight black jeans. Her hair dances in waves across her shoulders and down her back. Her eyes are bright.

I turn my head a fraction towards the still open door to avoid her gaze. I don't want her pity; the Tobias who fled from Abnegation is gone.

"Go back to Dauntless, Tris." My voice is so quiet that I start to doubt I even said anything at all. I still can't bring myself to look at her.

I hear her soft footsteps as she walks towards me. "Tobias, I-"

"Who told you?" The words are out my mouth before I can stop them, and I wince internally at the harsh accusation in my voice.

Tris sighs. She lowers herself down to sit beside me and places her hand timidly on mine. She gives me a small smile. "Nobody told me, Tobias. I figured it out for myself."

I turn my head a fraction to meet her gaze. "How?"

She raises a brow. "Are you sure you want to know?"

I nod my head, and she takes a deep breath.

"Firstly, I remembered something I'd read in Faction History; Eric is the youngest ever leader of Dauntless. He was a transfer who passed initiation just under two years ago. Then I remembered something you told me on my first day in Dauntless. You and Eric were in the same initiate class - the year that you ranked first."

She glances at me to see my reaction, but I just nod for her to continue.

"Since my father was a member of the council, me, my mother and Caleb were expected to attend the Choosing Ceremony each year along with him and Marcus."

I wince at the sound of his name, and my hands curl into fists. My temper spikes momentarily.

"Then I remembered what my father told me. "It said that Marcus' violence and cruelty toward his son is the reason his son chose Dauntless instead of Abnegation.""

Her brow is furrowed in concentration, and her lips are turned downwards in a frown. I fight to keep my expression neutral.

"But I couldn't seem to remember your name. When I first came to Dauntless, I knew you looked familiar, but I couldn't quite place where I'd seen you before. And then I remembered. Marcus Eaton, Tobias Eaton."

I realise that I'm picking at my nails, so I shove my hands deep into my pockets. When it's clear that Tris' story has come to an end, I give her a small nod. If she could figure it out, what's stopping everyone else from, too?

Tris shuffles closer towards me, and I let her. As I open my arm to give her better access, I lean back against the wall and rest my head against the cool steel.

We stay like that for a long time; Tris' head on my shoulder as we watch the city pass by in a blur of blues, blacks and greys with the occasional flash of white. We are so oblivious to the outside world that we don't even notice the sun slowly disappearing over the horizon.
