Sarcasm; the use of irony to mock or convey contempt.

“Quiorra, why is it that I always end up between the bad guys and you on a computer?”
I swiftly decided to ignore my assigned partner, the eminent Detective David Barreck as it were, along with the constant sounds of flying grunts and bruised egos. The flying fists and kicks behind me flowed just as swiftly as my fingers over the keyboard. After a few moments, the noise subsided until only my partner’s heavy, slow breathing came up behind me. I didn’t even spare him a glance or pause in my typing to answer the silent question in his brown gaze, knowing he was giving me an eager look.

His gaze moved over me, as if searching for something.
“Do you have a positive cell in your body..?”
I almost laughed at his defeated tone, as if he had already given up on trying to figure me out. However, my external expression hadn’t changed a bit as I continued my job. I finally broke through the firewall on the computer and smoothly plugged in a USB drive to start transferring the required information onto it. Finally, I removed my hands from the keyboard, turning the chair to look directly at the Detective. There was a bit of amusement in my eyes as I spoke with my usual heavy sarcasm.
“I’m positive you already have the answer to that question.”
He ran a hand through his ginger red hair as he...
