SPOILERS: IF YOU HAVEN'T SEEN THE DOCTOR WHO 50TH ANNIVERSARY EPISODE 'THE DAY OF THE DOCTOR', THEN I SHOULD WARN YOU I HAVE USED A LOT OF QUOTES FROM IT IN THIS CHAPTER.

Disclaimer: I do not own Doctor Who, BBC owns it. Any quotes used from any of the episodes also belong to the BBC.

"Right team, you stay here and keep me updated. I want you to find out where that spaceship came from, find out what UNIT are doing, and keep me updated on how everything is going", Jack said, talking to his Torchwood team.

(A/N – Sorry I put the Torchwood team as staying in Torchwood instead of going with Jack, as I said I haven't really watched much of Torchwood so I don't want to get the characters wrong. But I am trying to watch more of Torchwood.)

"We'll take my TARDIS as it is closer," 11 said.

10, 11, Clara, Martha, Jack and River all hurried to the TARDIS. 11 unlocked the TARDIS doors and they all followed him inside.

"Oh, you've redecorated," 10 said, looking round. "I don't like it.

"Oh. Oh yeah? Oh, you never do." 11 said frowning.

10 went forward to touch the console screen but 11 stopped him.

"Wait! The TARDIS will try to compensate for the different time zones if you touch it, wait until I stabilise it."

"So, where are we going? To see the spaceship?" Martha asked.

"No, first we go to UNIT", 10 decided.

"Why UNIT?" Jack asked.

"Because they are dealing with all of this", 10 explained.

"Yes, I'll call Kate!" 11 decided.

Clara gave 11 her phone.

"Who's Kate?" She asked.

"She's in charge of UNIT Kate Lethbridge-Stewart, daughter of Alistair Gordon Lethbridge-Stewart. She works for UNIT… actually slight problem there… my regeneration didn't meet her until 2012… Oh it doesn't matter."

11 typed a few numbers into the phone Clara handed him, and waited as it rang.

"Hello, it's the Doctor… yes, I'll hold."

Clara sighed and sat down.

"Oh hello, Kate. It's the Doctor, I need your help."

All the others could hear Kate talking on the other line.

"I'll be there in a minute!" 11 said into the phone, then handed Clara back her phone.

11 started to put the TARDIS into flight, and 10 helped him. Then they landed. They all walked out of the TARDIS, 11 in the lead. He swung the doors open to reveal UNIT.

"Which one of you is the Doctor?" A woman asked, walking towards them.

"Me." 10 said.

"And me." 11 added.

"Two of you? How can there be two of you?"

"Oh you know, it's all wibbly-wobbly timey-wimey", 10 explained.

"Right… well, I'm guessing you're here for because of the spaceship."

"Yep." Jack said.

"Kate, this is Captain Jack Harkness, Martha Jones, Clara Oswald and River Song", 11 introduced.

"Nice to meet you all", Kate smiled. "Oh and the spaceship, we found out something interesting about it."

"Oh, I'm sure I know what you found", 10 said, as they followed Kate down a corridor to a room with screens covering the walls.

"How can you? We only just found out ourselves", Kate said, looking confused.

"It's hard to explain, just something to do with my past, well our pasts", 10 said, pointing at 11.

"Yeah, you'll have to explain why there are two of you here, two Doctors. But for now look at this", Kate said, pointing to the main screen on the wall. "If you watch the path of the spaceship, it didn't came from space, it came from Earth."

Everyone watched, as they saw the route that the spaceship took.

"That's… odd. What's the point in that?" Martha questioned.

"It's a diversion. Something distract everyone", 11 explained.

"Distract someone from what?" Clara asked.

"From what they are doing. Right Kate, send at least 10 people to guard the prime minster, don't let them let him out of their sight", 11 said.

"Why 10 people?" Kate asked.

"Because if one of them is a Slitheen, then at least 9 of them are not."

"I'll ring the team, I've got some missed calls of them so they must know about how to spaceship didn't come from space. I'll asked them to check for anything else the Slitheens may be doing", Jack said, and then he walked out into the corridor to ring them.

"What are we doing?" Clara asked.

"Well after Jack has talked to the Torchwood team, we are going to take a trip to see a familiar face."
