Hannah clapped her hands excitedly, "Oh, I always wanted to go to the proms! Which one should we go to, Fenn?"

The TARDIS throbbed gently around them, a calm green-blue light coming from the glowing centre console. The Doctor walked around the console, flicking switches and levers, pressing buttons, and generally making sure his ship was still in good condition.

They had been through the usual "ooh"s and "aah"s that came when a new visitor entered the time machine- though these two girls had seemed surprisingly familiar with the TARDIS interior. Fenn could even name a few of the switches, and Hannah seemed very comfortable in his beaten-up chair. In fact, he had even received the comment, "It's not as big on the inside as I had though it would be."

He had, grudgingly, allowed these two girls into his TARDIS, hoping that they wouldn't be staying long. Fenn's intimate knowledge of the TARDIS and Hannah's over enthusiasm were starting to get on his nerves. He listened as they discussed the destination of their trip.

"Two thousand and eight. I want to see David's one," said Fenn, who had been studying the Gallifreyan symbols on the console monitor.

The Doctor nodded and typed in the date and location as Fenn recited it to him, "July twenty-seven, two thousand and eight, Royal Albert Hall, London."

The TARDIS landed with its usual sound- "Vworp," Hannah had called it- and the Doctor stepped towards the door, but Fenn stopped him.

"Sorry, Doctor, but if we're going to these proms, you're going to have to wear a perception filter of some sort."

"Why?" he looked at her, confused.

"Because you look exactly like the main actor, David Tennant, who isn't supposed to be here tonight." A strange look crossed her face for a second, and then vanished, "And you might want to wear a different suit."

The Doctor sighed and went off to change, seriously regretting beginning this adventure in the first place. But then an image of Rose's name printed on the cover of a book flashed across his mind, and his resolve hardened. He would do whatever it took to find out how his life had become just a source of entertainment for thousands of humans. Perhaps he could learn something; a way to bypass what he knew was yet to come. An echo of Ood Sigma's words echoed through his mind, 'This song is ending.' He didn't want to change and leave all that he was behind.  He looked at the TARDIS's massive wardrobe- what to wear?

Back in the TARDIS main room, Hannah was jumping up and down with an enthusiasm that was quite disturbing. Fenn looked at her, "Stop it, you'll hurt yourself."

She shook her head, "Nah, it's just that- IT'S HIM! We found him!"

"I noticed."

"You're acting very cool about it all."

"I am. I'm not sure how long this is going to last, and to be honest, bringing him to the proms is just dangerous. I mean, what if we get caught? Or, worse yet, what if he realises who we are?"

"We'll have to be super careful. You have a plan, don't you?"

"Sort of."

"Good. I like sort of. And thanks for calling me, by the way. I didn't want to have to chase you."

Fenn grinned, "I knew this was something you wouldn't want to miss. And plus, it would be a bother for both of us if I left you stuck in the twenty-first century, wouldn't it?" They both laughed at the absurdity of such an idea.

They stood grinning at each other until the Doctor strolled in, wearing a dark blue suit with a pale cream shirt that neither of the girls had seen before, and a TARDIS key hanging around his neck.

"Right then!" he said with his usual grin, "Did someone mention the proms?"
