The company looked frantically for a way out.

Proper Dave appeared in the opening in the wall. "Hey, who turned out the lights?"

"Run!" River shouted. She grabbed the Doctor's hand and flew down the narrow aisles.

The others ran after them.

The Doctor was too shocked to fly with her, and just let her drag him. He tried to help her, but she was flying so well he only slowed her down. "Where did you learn to fly?!" he questioned.

"From you," she answered with a smile.

"Who are you?!"

He knew it was supposed to be impossible to fly at all, but it seemed impossible to fly as well as she did. She could fly without flapping her arms. She could float motionless and suddenly dart off at full speed.

"Teach me?" the Doctor asked.

"I already did."
