Hello everyone! This is going to take place after Deathly Hallows (the book, not the movie) and not really a particular season in Supernatural. It should be fairly simple to follow and I am always taking suggestions! Read on, my little nerds.

Chapter 1

Hogwarts School Of Witchcraft And Wizardry

"The curse's been lifted, but I still can't find a professor for the defense Against the Dark Arts position. Nobody trusts it." Neville Longbottom said in defeat as he mulled through pieces of parchment with notes of polite decline. Minerva McGonagall sighed and rubbed her temples, deep in thought. It was August 24th and they were still in need of a professor in time to show them the castle. She reached into the pocket of her emerald robes and drew out a note with looped, elegant script. On it was three names followed by two American phone numbers. She handed it off to Neville, whose brow furrowed in confusion at the lack of explanation.

"Dumbledore left this to me in case I absolutely could not find someone to fill the position. It is a last resort, due to the circumstances of their lack of magical knowledge. They have been cleared by the Ministry to keep the secret, though they do not know that."

"But why would they come teach if they know nothing about magic?" Neville asked, his confusion still prevalent in both his expression and the tone of his voice.

McGonagall looked up and met her colleague's eyes. There was something in her eyes that Neville couldn't quite decipher. "Because we have no other options."

A Small Motel In The Middle Of Alabama

Dean Winchester washed the blood off his hands as his brother Sam cut up a copy of their fake FBI cards, getting them ready to burn. "ID cards are gone, I'll make up new ones tomorrow."

"Yeah that was a sloppy hunt. Why can't anything just go smoothly anymore? It's like after finding out about how awful most angels are, our hunts always go south." Dean dried his hands on the pale yellow, scratchy towels that all motels seem to have. He walked out of the bathroom, shrugged off his leather jacket, and sat on one of the two beds. "And where's Cas? I haven't seen him since-"

Dean was cut off by the flutter of wings and looked towards the door. Castiel stood there in his typical tan trenchcoat, white button up shirt, and black trousers. The blue tie around his neck was loosened and tied wrong, only further accenting his lazy-accountant look.

"Hello Dean." Cas said in his usual gravelly voice. He looked like he was going to greet Sam next, but he was cut off by the sound of one of the burner phone going off. Sam picked it up and walked out of the motel room, leaving Dean and Cas to an awkward silence. Dean took this opportunity to take several long swigs of beer to fill the quiet. Several long minutes passed before Sam came back into the room with a rather odd face.

"What's wrong? Smell something foul?" Dean asked jokingly, but Sam's face cut his quip short.

"I got just a call from a school. In Britain. Asking us to teach." Sam said in disbelief.

A WEEK LATER

"Couldn't you have just angel mojo'd us there, Cas?" Dean asked through clenched teeth as the airplane started down the runway.

"The lady-McGonalgo something-said we would have to take a train with the kids and other teachers." Sam said in exasperation. He had been dealing with his brother's whining and complaining about Sam's lack of information, but they all agreed that the pay was honest enough and interesting. Castiel was strangely excited about the prospect of teaching, even if they didn't quite know what they were up against.

"Look, Dean! Look how far up we are going! We are really flying!" Cas was almost vibrating with his face pressed to the window of the plane. Sam looked over Cas and Dean to see Atlanta's sunset as they started over the Atlantic to the Luton Airport in England. Cas immediately called dibs on the window seat, so Sam ended up in the worst seat possible for an 8 hour flight- the aisle seat. After a half hour of listening to Castiel's theories on the centre of gravity having an effect on flight time and Dean's increasing anxiety, Sam ended up dosing both with sleeping pills. Cas's head fell down to Dean's shoulder, prompting Sam to put a blanket over them and take a picture for future blackmail evidence.
