So this is my first ever cross over fic all based off a post on tumblr, It is a huge WIP but I will be updating it as often as I can and hopefully it will be finished in a reasonable amount of time! (Also apologies for the very short first chapter).

"Dude there is no way it's another Wendigo. We ganked one in the same territory two days ago! There is no way they would be 'sharing' the same area."

"I know they are territorial Dean but all of the research points to another one." As he spoke to Dean, Sam theatrically waved his arms over the table he was working at.

"Fine, whatever can we just go and kill this thing. I think we are due a quiet break after this." Sam merely stared at him after he finished speaking which after not too long started to creep him out slightly,

"Why are you staring at me like I have grown another head?" It took Dean more than a moment to being to fathom the look of surprise on Sam's face but it became all too clear as a gruff voice behind him caught him unawares.

"Hello Dean."

"Oh sh.." Dean jumped and spun around immediately to find Cas in what could only be described as well into his personal space.

"You really need to stop doing that!" Cas simply raised an eyebrow and stared at Dean, essentially daring him to say something else before he stated why he was there.

"I have an important case that you two must attend to immediately."

"Come on Cas, you know we are busy here!" Sam nodded in agreement and looked up at Cas from his seat at the table,

"He is actually right, we are right in the middle of a hunt and it is pretty time sensitive so we need to get it done. I'm sure it can wait." After he had said his piece Sam immediately returned to the piles of books and heaps of paper before him in an attempt to figure out where the Wendigo would be.

Dean moved over the motel room to sit on the edge of one of the beds but stood up immediately after Cas finally decided to say what the case involved,

"I may have tracked down Crowley."

"For god's sake Cas why didn't you say that straight away?! I'm sure a Wendigo can wait while we get this son of a bitch."

Sam immediately left the research in favour of getting up to get their things together, the piles of work left on the table being a strong indicator of how bad they wanted to find Crowley.

He turned to Cas, his face set,

"Give us ten minutes to get everything together and we can leave." There was a barely there nod from Castiel before the brothers started packing, plaid shirts on top of shot guns and blue jeans on top of holy water.

As soon as they had their small amount of belongings ready in duffel bags that were slug over each of their shoulders they walked over to Cas, who was still standing in the centre of the motel room.

He merely stood there and stared at the brothers before Dean released an impatient sigh then broke the silence,

"So where is this gig?" Dean regretted asking, as he barely had time to react never mind protest, before the angel grabbed their shoulders and 'zapped' them to their destination; favouring speed over comfortable travel.

It took a minute of slightly dazed confusion and getting their bearings before they could stand up properly and walk around to investigate their surroundings.

They seemed to be in a typical run of the mill alley lined with brick walls; at least Cas was smart enough to not get them seen.

Dean took in the sheer amount of people as they walked out of the alley onto an incredibly busy road, as soon as he spotted the vast billboards he turned to Sam,

"Hey, are we in Ney York?" Sam simply furrowed his eyebrows and as soon as he spotted the unmistakeable red of a double decker bus his suspicions were confirmed, though he couldn't hide the shock on his face.

"Dean… this is London."

"What!?" Dean quickly spun around and took in the sight, bright red buses were going past with black cabs behind them, a billboard for London's west end flashing before them.

"Oh my god. We are in London. Like American Werewolves in London, London." Both Sam and Dean were lost for words while Cas stood and watched them, as if randomly appearing in London was the most natural thing in the world.

"Cas, what the hell!?"
