The Doctor felt lonely today - as every day. No companions with him today, no one to go with him and confort him, hug him, talk to him. It would be easier if Amy was here, but she's not, nor she will ever be again. He lost both Amy and Rory for good now.

So he decided to take someone to a beutiful adventure with him, to show another person those beautiful shining stars.

After a long walk in the park, the Doctor liked America, as well as any other country in the world. He liked the people, the cities, and all those beautiful, breath-taking, places across the States.

But he didn't know how to take anyone to that adventure. Should he just appear to someone, and be all like "Hey, name's the Doctor, I'm an alien from the plannet of Gallifrey in the constellation of Kasterborous; and that blue police box out there is my Time machine called the TARDIS which can go anywhere in time and space, so come with me"?
'course not. That would be stupid. But how to take someone with him?

Today was a good day for Castiel, because he didn't have any priorities to do. Of course, he could just go and see Sam and Dean and help them in their hunter business, but why not just be free of any work today? Why not just enjoy the beautiful planet of Earth?

Cas always wondered if there was life outside the Earth. God didn't speak with this to other angels, nor did any of the angels know about that; but he heard once someone speaking about how God actually has a large group of angels for every single planet to protect and keep from danger. Was this true or not, he didn't know, but he always wondered about it. He couldn't leave from here, he loved the Earth and the people here, but he just always wondered about it.

Few hours later, he ended up running away from a bunch of powerful demons, and as he ran away in this little street, he was just running and running and came to an end of it. That's it, nowhere to go, there's just a big wall. Where to go now? He could face them, but they were really powerful.

But he saw this small blue police box next to the wall and when he tried the door - they opened. So he got inside as quickly as he could and shut the door.

Castiel felt relieved because he escaped them, but they could still break in. He opened his eyes. He saw that he's in some sort of... well... something big. He starred at the walls and everything around him, as he entered something that he didn't quite understand.

"Um... wait... what? Where am I?", he said out loud.

As soon as he said that, a man approached him.

"Oh, hello, and you are?"

"Who are you? Where am I?", Cas asked.

"Okay, just... calm down. I'll explain everything."

Cas looked at the man. He looked like a very clever man, but childish one. He was wearing a fez, and was holding two bow ties in his hands, as he was picking wich one to wear.

"What do you think?", the Doctor asked.

"Huh?"

"Bow ties. Which one should I put? I always wear bow ties... you know, bow ties are cool, aren't they?", the Doctor smiled.

Cas was just looking around. He didn't know where he was, and who this man was, but besides of feeling a bit scared, he also felt astonished.

"Look, I don't know who you are, but I swear that if you're one of the demons..."

"Demons? Demons? Doesn't God and the angels take care of that?", the Doctor chuckled.

"Do you..."

"Know God? Yup, but it was a long time ago, me and him don't really have any business to do together. But, yeah, I did meet him. Quite an interesting man, I'd say. I mean, course he's not interesting like me, but I'd recommend him a bow tie. It would really match that thins he's wearing."

Cas looked surprised, and a bit confused.

"Huh... interesting... my name's Castiel. I'm an angel of the lord."

"Well, Castiel, nice to meet you. It was two hundred years ago I've spoken to some angel. How are you?"

"Two hundred years? How could it be two hundred years? You couldn't have possibly lived that long. And where am I?"

"Well, let's go from the beggining. I'm the Doctor, I'm about one thousand years old, I'm the Time Lord from the planet of Gallifrey in the constellation of Kasterborous; and you are currently in the TARDIS, which is my time machine that can go anywhere in time and space."

"Wait... what...? So... um... you're what... an alien?"

"Yup, alien. More precisely - a Time Lord."

"And this thing... this thing, right here... goes anywhere in space?"

"Hmh... um... yes. Most people are interested in that "time" part."

"So we can go anywhere in space? Can we go somewhere else? I've got a few demons chasing me."

"Oh well, that's no problems, those doors can keep us perfectly safe. But, if it makes you feel better, we can go anywhere we want. Hmh, how about the moon? Fancy a trip there?

"Woah... um... okay", Cas smiled.

"Okay. Make sure to grab onto something."

The Doctor pressed some buttons and pulled some leverages as he yelled "Geronimo!"
