The next day, I flew over to an old warehouse. It hadn't been used in years. This was where I told the Doctor to meet me. I perched above in the metal rafters where it was too dark for anyone to see me. There, I waited. It was a few minutes before I heard a door open. The Doctor walked in, and glanced around. "Are you here?" He called out.
"You came," I said.
The Doctor looked around some more. "Where are you? Why won't you come out?"
"I had to make sure you didn't bring anyone," I replied. I noiselessly glided down from the rafters and landed behind him before folding my wings across my back. The Doctor spun around in surprise.
"Oh," he said, looking at my wings. I stretched them out to their full span so he could see them better. "You are beautiful." He nodded towards my wings. "May I?" I nodded, and he stepped forward and ran his fingers along my wings. "How are you able to fly with them?"
I shrugged. "I'm not exactly sure. I'm guessing my bones are hollow."
He scanned me with his sonic screwdriver before flicking it up and staring at it. "Yes. They are. And your heart and lungs are more efficient than a normal human's." He glanced at his sonic screwdriver again, then froze.
"What?" I asked.
"But..." The Doctor's voice was a whisper. He continued to stare at the screwdriver.
"Doctor," I said uneasily. "What is it?"
The Doctor glanced up at last, looking as if he had just broken from a trance. He gave me a quick smile, and put his sonic screwdriver away. "It's nothing."
I knew he was lying, but I didn't question him further.
