I drift back to consciousness, the world slowly coming into focus as I emerge from the inky blackness. My head throbs and my limbs feel heavy, like lead weights pinning me down. I blink, trying to clear the fog from my mind, as I become gradually aware of my surroundings.

I appear to be in one of the cryo-chambers, the lid open and a chill mist swirling around me. The cold air nips at my skin, sending a shiver through my body as I start to regain sensation.

Memories start to filter back, fragmented and unclear, but the general gist is horrifyingly apparent. Aperture Science... the tests... GLaDOS. A surge of anger flares up inside me at the thought of that sadistic AI, the one who orchestrated the demise of everyone in this godforsaken facility. Including my own mother. My hands clench into fists, my nails digging into my palms hard enough to draw blood.

I take a deep, shuddering breath, the air filling my lungs for the first time in... I don't even know how long. A lifetime ago, maybe.

I survived it all, but at what cost?

As I slowly sit up, my muscles protesting the sudden movement, I see you standing next to the cryo-chamber.

I blink again, certain I must be hallucinating. There's no way there could be another survivor. Could there? But you remain.

I open my mouth to speak, but my throat feels like it's lined with razorblades. I have to swallow hard before I can manage a raspy croak. "Who... who are you?" I ask, my voice coming out harsh. My instincts scream at me to be wary, that this could be another trick.
