Tris' POV

I feel like my body is frozen. I can hear Four's footsteps growing quieter as he gets further and further away. My heart is screaming for me to follow him, to offer any sort of comfort that I can. But my mind tells me that it's too late. He knows that I know who he really is. The look of shock and anger on his face when I almost slipped up was all too clear.

I feel numb, like all the emotion has been drained from my body. My mind is clouded, and I find it hard to form a coherent thought. I can vaguely hear voices around me, but they're simply noises, nothing more than a blur. My hands clench into fists in my lap, and I see my knuckles beginning to whiten from the sheer exertion. Only then do I realise that I've lost him before I really found him.

Something sharp jabs me in the ribs, but I don't react. I feel a dull ache resonate throughout my body, starting at my chest and spreading slowly but surely. I feel like my heart is breaking in two, and I find it difficult to understand why. I never knew Four, not really. He was merely my instructor; the person who helped me by pushing me to be the person I am today. Without him, I wouldn't be here.

Yet I can't shake the uneasy feeling that grips at my every nerve. He was so much more than that, yet I have denied it for so long, dismissing the thoughts almost as soon as they were formed. He is the same person that he has always been, but knowing that he is from Abnegation brings me comfort. I feel as though I finally understand who he really is.

"Excuse me," I mutter, unable to stop the words from pouring out of my mouth. I push back from my seat and head towards the door.

I search my mind for something; anything. I try to put myself in his shoes; if I needed to get away from somewhere, where would I go?

Without a specific destination in mind, I find myself being propelled forwards, as if I have lost complete control of my body. I push myself to run faster; my lungs burn and my chest aches painfully. I do not know where I am going, but I can feel him. Something within me is pushing me to follow him, though I cannot exactly pinpoint where.

Soon enough, I reach the tracks. My eyes dart around aimlessly, searching for any sign of danger. A layer of clouds cover the sky, the moonlight piercing through with a strange sort of intensity that I've never noticed before. In the distance, I hear the faint sound of a train horn, unidentifiable to those who aren't specifically listening for it.

Up ahead, I see a dark figure standing at the edge of the rooftop, their stance rigid, ready to jump when the train presents itself. I start out at a jog, my legs aching from earlier over-exertion. When the train's lights come into view from the corner, I find myself running faster, my arms outstretched to pull myself inside.

I land with a dull thud on the cool metal, and I pull myself upright into a sitting position. Only then do I realise how tired I really am. A dull ache spreads throughout my body, and my head pounds violently. I lean my head against the side of the cart, allowing my eyes to slip shut for just a second.

A few moments later another person enters the cart. They are dressed all in black, a clear indication that they're Dauntless. My head snaps up, and my gaze meets theirs. His startlingly blue eyes bore down into mine, filled with shock and a twinge of sadness.

I feel my heart rate increase, and I release a breath that I never knew that I was holding.

"Tobias," I whisper.

A/N: Thank you so much for reading! Like I promised, I tried to upload this chapter yesterday after I had written it, but every time I clicked publish, the site kept saying that my format was invalid :(

So here it is, just like I promised :)

I know this chapter hasn't actually included the game, but I've realised that I haven't included any FourTris fluff as of yet, and this is leading up to that :)

The next chapter should be in Four's POV, but I'm going to go back to the game with the other characters for one chapter.

What character's POV should I write in?
