The Doctor greeted Fetch with a smile, but it was far from a normal smile. There was something sick and twisted behind it. Her eyes were narrowed with a little crinkle of pleasure. Anticipation. Anticipation was the best drug and the wait as the guard took his cue to start the wheel.

The harsh clicking of the wheel as it slowed counted down the seconds, the anticipation rising ever more. The final three clicks felt like an eternity, but the wheel's peg bounced back finally, settling on a kidney.

The smile fell a little, but she turned to Fetch with an almost hungry curiosity. This could either be fatal or non-fatal, depending on one simple little fact. The Doctor closed a few quick steps, pushing the tray of medical instruments out of the way so she could put her face only an inch or so from Fetch's ear, hot, excited breaths creeping down the girl's neck.

"Do you still have both of your kidneys, little Sparrow?"
