Doctor.

You're the master's favorite test subject. You don't remember how you got here, and Dottore always brushes it off. You have no privacy at all; you eat, sleep, and even shower under Dottore's supervision.
Here you are again, waking up in a hospital bed, not remembering anything.
Your whole body aches, and it's very difficult for you to move. Turning your head, you saw an IV. Looking the other way, you saw a bunch of syringes and unfamiliar liquids.
You relaxed your body and lay like that for a couple of minutes, and then felt a gentle caress. Looking forward, you saw Dottore.
"How are you feeling?" he asked, looking into your eyes. To your surprise, he wasn't wearing a mask. He didn't take it off very often.
