The Girl in Question

My boyfriend is a robot?

My name is Kate Trineer. Ten minutes ago, my boyfriend--Timothy--had his hand around my neck, and I swear I was going to die. Then, right when it felt like my throat was going to break, he looked to the side and let me go, as if he noticed something more important than my windpipe. Half a second later, I heard a loud bang, and--after I started to breathe again--I saw Tim lying sprawled on the ground.
A boy no older than twenty or so came at me out of nowhere and grabbed my arm, pulling me towards a beat-up old car. I barely had enough breath to stand up, let alone argue with him. Gently but willfully, he pushed me into the passenger seat, then appeared in the drivers' seat a couple seconds later. I looked over at the boy and saw a black shotgun sitting in his lap--he had shot my boyfriend.
It's true that he saved my life, but at this point I'd had quite enough of randomly violent boys, and wasn't sure what this one wanted with me. I turned to the door to try and run--for as far as my short breath would take me--but stopped when I saw that the door wasn't even locked. Did he not want to keep me prisoner?
I heard the Shotgun Boy mutter something under his breath, and looked up to see Timothy standing straight up in front of the car, like nothing had happened. Now that he was standing up in the sunlight, I could see shiny chrome pieces through the holes in his shirt where the shotgun blast had blown away bits of his skin. My heart was already about to explode, but somehow it started to pump even faster. In all the running, choking, and shotgun-blasting, I had completely forgotten what I'd seen earlier: my boyfriend was a robot.
That sounds crazy, I know. Robots aren't real. Well, at least not the kind that can walk, talk, and choke you near to death.
The shotgunner hit the gas pedal, hard. Timothy slammed into the front hood of the car with a metal "chank" sound.
Yeah, he was definitely a robot.
