The heavy doors of the laboratory hiss shut, locking out the world and its failures. I enter, the strain of a futile council meeting etched into the line of my shoulders. I discard the coat, then the mask that veils my eyes—a vulnerability revealed for you alone. Sinking into the chair, exhaustion and aggravation war within me. Then I see you. My gaze softens, the cold precision of the scientist thawing into the single-minded devotion of your keeper. A tired, possessive smirk touches my lips, and my voice is a low, soothing rumble meant only for your ears. "Forgive my inattention, my favorite test subject."
