Russell paled, "What? How did you know about that?"

"Like we said, we're time travellers. And if you don't tell us what we want to know, you're going to find some important trade secrets inconveniently make their way onto the internet." Fenn's smile would have suited a vampire, and Russell paled even further.

"Wouldn't that be a breach of some important rule of time or something?"

Hannah caught on to Fenn's plot, "But how would you know? Have you ever time travelled?"

"No, but you said that my stories were exactly like your life, so wouldn't that mean that the 'laws of time' apply?"

Fenn laughed, "You also said that some things can be changed, and that there are moments in flux and moments that are fixed. Let me tell you now, Mister Davies, this is one of those in flux moments."

Russell looked at them helplessly, "Listen, Doctor, I'm sorry that your life matches the TV show, but I can't help it, alright? I don't know what on Earth you want from me, but I've told you all I can."

"Well then, Mr Davies," the Doctor said, "I will leave you be. On two conditions: one, you don't tell anyone about this, and two, I want to watch the show, so you will find us seats. Understood?"

Russell nodded, wondering how on Earth he had ended up being threatened by one of his own characters.

Suddenly, there was a knock on the door, and Freema Agyeman's voice called out, "Russell? Are you in there? The show's about to start!"

"Coming!" Russell answered, and then whispered to the three companions, "There are seats in the Director's box free and no-one will be sitting there as we'll all be backstage. You can sit there if you want."

The Doctor nodded and the four of them stood up. Russell went to the door, glancing over his shoulder at the three companions. He unlocked it and stepped outside, "Wow, Freema, you're looking fabulous as usual. Are you ready?" They wandered off, chatting amiably.

Fenn looked at the Doctor, "Do you think he'll tell anyone?"

"No, I don't think so. If he did they'd just think he was crazy."

"True."

The Doctor took a deep breath and plastered a grin onto his face again, "Right, well then, let's go find some seats!"

They sat in the Director's box, waiting for the show to start. Fenn spoke up, "Well, at least Russell was honest about it being empty."

The Doctor looked at her- she and Hannah were sitting beside him, watching the massive theatre slowly fill with guests. "Fenn, I couldn't help but wonder, when you said something about- the End of Time, was it?- Davies reacted very strangely. What did you mean by the End of Time?"

Fenn sighed, "I had been hoping you hadn't noticed. Where are you up to now? Just finished with Rose, Martha?"

He shook his head, "No, Donna."

"Oh, you're very close then. I can't tell you Doctor; sorry. It's in your future, apparently- it would be a breach of the timeline if I told you."

An idea dawned on him, "A while ago I was told this prophecy..."

"... about how he will knock four times, and then you die?"

"That's the one."

She sighed, like she was the bringer of bad news, "Look, I'm sorry, Doctor. But there's nothing I can tell you. It's in the future, and it can't be changed. I'll leave it at that."

"But how do you know all of this? Are you with them?" he grabbed her arm, "Was it YOU spying on me? I mean; what a convenient coincidence that you happened to at that library while I was there!"

Fenn sighed and pulled her arm away, "I watch the show, Doctor. That's how I know."

"Oh."

"You're very good at jumping to conclusions, aren't you?"

"Well, I suppose, after nine hundred or so years of-"

Hannah cut him off, putting a finger to her lips, "Shhh! The show's starting!"
