Scar

Bullet.

A man, approaching his late twenties maybe, a cube on his back. Rushing through a room, as a turret shoots. Then, bullet connects with his thigh and he falls.

I woke up to find I was back in the chamber. I could only see out of one eye. I sat up. Mimi, Phoenix, and Wheatley were sitting around me. "lay back down." commanded Phoenix. I did as I was told. She took some antiseptic wipes and scrubbed at my eye washing off most of the blood. I could see again, and the swelling was going down as she cleaned. Wheatley looked so frightened it was almost funny and Mimi was visibly shaking. "Done" said Phoenix as she finished. I sat up. I looked over at Wheatley and he gasped. I ran over to the pit of liquid. My reflection was hideous. My white t-shirt was more of a dusty color. My usually long, wavy dark hair was messy and in knots. My arms and legs were long but not enough to make me tall. My eyes were wide with shock, and there was a long jagged scar across my right one. I stumbled back, terrified. I ran over to the first aid kit and grabbed the scissors. I began hacking away at my hair, cutting it just below my shoulders. I took two elastic bands and put my hair up in pigtails. I took a bandage and wet it with spit. I began to wash off my face. I put everything back in the kit and turned to face my friends. "If we're going to find your body we need to go down beneath Aperture." I said to Wheatley. He looked puzzled, "How did you know that?" he asked. I stopped for a second. How DID I know? "Instinct?" I guessed. "And just how do you plan on getting us underground?" asked Mimi. I smiled dangerously, "We'll have to break some stuff." Phoenix let out a cheer. "Time to go tick off some robots!" she yelled. I laughed, this was going to be fun.

If we didn't get killed in the process.
