Amy goes with Romana.

Amy squirmed as Romana dragged her through the TARDIS corridors, pinching her ear so firmly that she couldn't wriggle away. She squirmed even more as a door slid open and she was dragged into what looked like a lecture theatre full of interested students.

"Excuse me. Coming through. Don't mind us."

"Aah! What are you doing?"

"What? It's a short-cut. Don't you know this already?"

Amy yelped and tried to cover her naked body with her hands as the lecturer faltered and the students turned in their seats, straining to get a better look. Romana was pulling her up the stairs towards a door at the back of the theatre. "Short-cut? How am I supposed to know that? Let me go!"

"Why?"

"Because... you know why!"

"I told you. You have to come with me. Your gymnotemporal signature's wrong."

"So?"

The door at the back of the theatre swung open. Amy breathed a sigh of relief, which was cut short when Romana pushed her through it. On the other side, strobe lights flashed and music pulsed.

"The TARDIS has a nightclub?"

"Of course. Now come along, we have to get you to the Punishment Chamber."

"What?"

"Don't worry, it's just a nickname - come back here!" Amy had broken free of Romana's grip and was sprinting across the dancefloor, which was packed with gyrating people in futuristic costumes. Some of them, she noticed, had three eyes and antennas. Not that she had time to notice much. Being stark naked in the middle of a crowded room, running away from a maniac, made it hard to focus on anything else. She elbowed her way through the crowd, drawing stares, dodging as many hands as she could, her cheeks flaming as a stranger's fingers snuck through her defences to pinch her beautiful bare bottom.

She looked back over her shoulder. Romana was gaining on her, looking angry. She didn't like her chances, or the sound of the Punishment Chamber. There had to be a way out!
