Sam and Dean walk into the library of the MoL bunker each holding a beer.

Sam: Dean, the Darkness may be something that we aren't able to kill. Last time it was out, it took God, all of the angels, and Death to put it in the cage.

Dean (pointing across the room): Sammy what the hell is that?

Camera pans around to see a big blue box sitting by the tables in the library, papers scattered like there had been a breeze. Castlel pops in beside the boys.

Cas: Sam, Dean, this is a sign, this man has came a very long way to help us.

The door to the box opens and out of it pops an angry looking older man and a beautiful, young girl.

Clara: You really need to learn to park that thing!

Doctor: Shut up woman, I'd like to see you do better.

Clara: River could have done better.

Doctor (pressing his finger to his lips): Shhhh.

Clara: Oh no, don't you shhhh me…

Leaving her sentence unfinished her attention going to the three people staring at them with disbelief.

Doctor: Hello, I'm the Doctor. I'm an alien, a Time Lord from the planet Gallifrey. You're (nodding towards each individually) Sam and Dean Winchester and Castiel. I got a message from an old friend saying that you may need some help. This is my um, traveling partner, Clara Oswald. She's human, from London.

Cas: Who sent you? Who is this old friend?

Doctor: You call him God, to me his name is Chuck.

Dean: Whoa! You know God, THE God on a first name basis?

Doctor: Yes, I knew Death too, old friend, before you two went and killed him.

Cas: Do you know where God is now? We need His help!

Doctor: Well, yes, he's vacationing on Planet One right now, admiring his handiwork. However, that's why he's sent me. I know that you are up against the Darkness, and that you could use all the help you could get. Clara and I are here to offer up some. But first there are a few more players that we need to round up. Everyone on no account follow me into this box.

Dean: Hell no, I'm not randomly going into a box with you! We don't even know you.

Cas: Dean, this man was sent here by God to help us. Speaking of…You said that you know God as "Chuck", does this Chuck have a last name?

Doctor: Sure he does, most people do, except me….I'm just the Doctor.

Cas: Well, are you going to tell us?

Doctor: He will for himself when he's ready for you to know.

Sam: Look, you may be telling the truth, but how can we know for sure?

Dean: Yeah, you just show up in our bunker and expect us to take everything you say at face value? Then expect us to follow you into that box? How the hell did you get that thing in here anyway?

Doctor: Yes, yes, I flew it.

Dean (nervously): Flew? Look if we're going somewhere we'll drive. Baby is parked right outside.

Doctor: Dean, you can't drive where we're going. Your car won't make it across the Atlantic Ocean.

Dean: Ocean? We're going to Europe? Why?

Doctor: There are a few more people we have to pick up first. Eleven to be honest. We're going to have to make a few pit stops in London, a prison, a parallel universe, and I believe the other two are in France right now on their honeymoon.

Sam: Fine, but we have conditions first.

Doctor: Ok, what?

Dean and Sam get some Holy Water, a silver knife, and Cas gets out his Angel Blade.

Clara: What do you think you're going to do with those?!

Dean: We've got to make sure you are who you say you are.

The Doctor extends his arm to allow the boys to do the tests and motions for Clara to do the same.

Dean: Ok, so you're not demons, shifters, ghouls, or angels, but aliens aren't real!

Doctor: Sure they are, there are more kinds of life out there than you could possible imagine! Time Lords, Daleks, Cyber Men, Sontarans, the Ood, the list goes on and on boys.

Cas: He's right Dean. Humans are not the only lifeforms in the universe.

Doctor: Ok, now lets go!

Inside the Tardis Dean and Sam look around bewildered by the size of the control room.

Doctor: Clara, would you take care of that for me?

Clara: It's called the TARDIS, Time And Relative Demensions In Space, the Doctor uses it to travel though time and space, helping people whenever he can. It's bigger on the inside because the Time Lords used some kind of dimension thingy to make this box livable. Also, no, it's not actually made of wood.

Dean: Son of a bitch! This is awesome! Sammy, we could save so much time with one of these!

Sam: Yeah, we could take the whole library with us too.

Doctor: Alright, first stop, 221 Baker St, London.

Sam: Sherlock Holmes? (Chuckles) Yeah, right!

Doctor: No, really, we're also going to get John Watson and his wife Mary while we're here.

Sam and Dean look dumbfounded, but take the Doctor at his word.

The TARDIS takes off and rematerializes and the Doctor leaves the controls.

Doctor: You may open the door.

Cas turns and opens the door and three people briskly walk through the threshold directly past them. Sam, Dean, Clara and Cas follow them down to the controls where the Doctor is.

Sherlock: Oh, hello again Doctor.

Doctor: Sherlock! (reaching to shake his had) John, how've you been? (kissing Mary on the forehead) And Mary, good to see you all again!

Sherlock: So, the Darkness, I presume? These two are the ones who let it out? Figures, Americans, always going headfirst causing more problems than they solve.

Sam and Dean together: Hey!

Doctor: Only a few more stops, France is next!

Dean (under his breath to Sam and Cas): I'll show him headfirst…

The TARDIS Materializes and the doors automatically open, in rushes a young, black couple.

Martha: Doctor? You've regenerated!

Doctor: (hugging Martha Jones) Twice since you last saw me, a whole new set of regenerations now! Mickey! (jumps over to hug Mickey now)

Martha and Mickey introduce themselves to everyone and settle next to Clara by the time the doors open again.

River: Hello Sweetie! It's about time you show up at my doorstep, I've been waiting for ages! Oh, and you brought others, must have a special night planned for me then!

Doctor: (kissing River as they take the controls together) River, how've you been?

River: Where are we off to then?

Doctor: Cardiff, but firstly, this is (going around the room) Sam, Dean, Cas, he's an angel, they're Americans, Sherlock, John, Mary, Martha, and Mickey!

Cut to a view outside of the newly rebuilt Torchwood tower in Cardiff. TARDIS materializes.

Now cut inside of the Hub. Jack, Gwen, and Rex are sitting there around a table when they hear the wheezing sound. Jack jumps up and runs to the door, Gwen and Rex follow blindly.

Cut inside of the TARDIS. Jack and the Torchwood group run through the door.

Jack: Doctor!

Doctor: Jack, Gwen! Good to see you both again!

Gwen looks confused.

Jack: Don't worry Gwen, its the same person he can regenerate when he's dying.

Doctor: Aye, 've done it twice since we last met. And who is this, Jack?

Jack: Doctor, meet Rex Matheson, American member of Torchwood. Since the Miracle happened he's had my gift and has been unable to die.

Rex: Some gift…Nice to meet you sir, I've heard a lot of good things about you from Jack!

Doctor: Nice to meet you too, Rex. Looks like you're tagging along.

Dean: The Miracle? You mean when no one died for a few months a while back? That wasn't a freakin miracle, Sam and I were investigating that but couldn't get any where on it.

Jack: We finally figured it out, and stopped those responsible.

Doctor: Alright everyone, come here. (He shows everyone what to do to help him fly the TARDIS through the rift.) There is a rift here in Cardiff that we're going to have to fly through, it's going to be hard.

Jack: Rose?!

Doctor: Rose!

They all take their places and safely navigate the rift. The TARDIS materializes on the other side in the front yard of Rose's house. Cut to the kitchen where Rose and 10.2 are inside making breakfast.

Rose: Did you hear that?!

10.2: No way, it couldn't be….

They run out the door and see the TARDIS. Excited, Rose rushes through the doors.
