A white-hot glare over-whelmed me and I crashed into another place, another time, felt myself slip out of the man's arms and into another space. Light whirled around me. I felt hollow, incomplete, torn apart... and then I forgot everything else... and I slept.

Air was forced into my lungs and I woke abruptly, gasping, a hand clutched to my chest. It felt like I'd been running for miles and miles, my chest was thudding so fast I couldn't keep up with the beats. My entire body tingled like I'd just received an electric shock. Opening my eyes, I realized that I was once again in a dim tunnel, and the air felt colder than ever. Slowly, very slowly, I tried to sit up. I managed it, but my lungs felt like they were pounding and I glanced down at myself in concern. Everything looked fine, there weren't any obvious injuries and extra limbs.

I shook myself, attempting to clear my head, trying to make sense of the images I'd seen of my mother and that man... the man with the familiar voice.

What the hell..." My chest felt like it was vibrating, trembling, and I tentatively reached up a hand to feel my heart. It seemed fine, thumping away at a normal pace. It seemed a bit weird that I could actually feel my heart beating from the outside, but at least I was alive. The fluttering feeling continued, and I felt a ripple of uncertainty go through me as I slowly moved my hand over to the right side of my chest. I gasped suddenly, whipping my hand away and staring down at myself.

I felt another heart beat there.

For a long moment I stayed very still, trying to understand what was going on with my body. Slowly, inching, I raised my hand back up and placed it against my chest. Yes, there was a beat here as well. I put my other hand on my chest, feeling where I expected to feel my heart normally. The two rhythms didn't line up at all, but came one right after the other, almost like... almost like...

I have another heart.

An involuntary sound escaped me and I leaped to my feet, still clutching at myself. In a bit of a panic I looked around myself wildly. Lying on the ground where I had been was my silver watch, opened and nearly snapped in two. Beside it was... a sonic screwdriver. Swiftly I bent and scooped up both objects, examining the latter closely as I did so. I couldn't tell if it was the Doctor's, I hadn't seen his close up, but it definitely was a similar model, at least. Not having the slightest clue what to do with either the screwdriver or the watch, I pocketed both of them and looked around once more.

"YOU ARE SERVING YOUR MASTER WELL, SLAVE."

I nearly jumped out of my skin, and my new twin hearts crashed in my chest.

"What... what the hell is going on?" I shouted, "Where's the Doctor? What have... what have you done to me?" I could feel tears in my eyes as the panic overtook my anger at not finding the Doctor. I was truly frightened at what was happening in my body; there was so much energy coursing through me that it felt like I was about to explode, and my hearts throbbed relentlessly as they pumped the energy through me.

"YOUR PHYSICAL CONDITION IS STABLE," the metallic voice continued, "YOUR BODY IS NOW MORE SUITED TO THE TASKS AHEAD. YOU STILL HAVE TIME TO FIND YOUR MASTER... JUST ENOUGH TIME..."

Turning, I began the jog down the hallway, feeling my legs surge with power and my lungs expand like they never had before. I felt like I could run forever and not get tired or out of breath. The metal voice followed me, screeching louder this time,

"FOLLOW THIS TUNNEL TO THE NEXT TASK. BUT REMEMBER: THE DOCTOR DESERVES HIS PUNISHMENT. YOU NOW HAVE THE TOOLS TO ESCAPE NOW AND LEAVE HIM TO HIS FATE."

"Screw that!" I cried, running faster now, feeling the slope of the tunnel floor as it began to descend lower, "Don't you dare think for one second that I'm going to let you freaking douche bags keep him! Think again!"

Feeling another surge of power, I sprinted full-tilt down the tunnel, down and down until a wall appeared in front of me, a door slid open, and I rushed through it.
