It was the single ray of sunlight that made its way through the gap in the curtains and hit him directly in the eye that finally woke Dean up. He sat up suddenly, trying to avoid being permanently blinded. Blinking back to reality, Dean quickly noticed the lack of Sam on the other couch.

"Sam? Cas?" Dean called out quietly, his eyes scanning the room for the first time. Last night had been one hell of a ride so he didn't really have time to stop and look at the view. The house was surprisingly nice but something about it seemed a little off to Dean. He felt as though it was more looked at than lived in. He was pulled from his thoughts when voices hit his ears.

"I think you'll find I was here first, therefore it's mine"

"Well I live here, so I have more power than you"

Dean raised an eyebrow and headed towards to voices; into the kitchen. This was where he found his brother and Trubel standing impossibly close together, glaring at one another. After a quick survey of the situation, Dean almost burst out laughing as he realised they were arguing over none other than the last bowl of cereal.

"Well, I'm taller than you" Sam said with an almost child-like tone of voice. And Dean had to hand it to Trubel that she wasn't even slightly intimidated by his brother's height.

"I have a machete leaning by the door"

"I have a gun on the counter"

Dean knew there was no power in their words but he did not want a repetition of last night, so he stepped forward to interrupt them. But just as he opened his mouth to speak, Nick suddenly appeared out of nowhere behind Trubel, slid his arm behind her, and stole the cereal from right under their noses. To which both of them erupted into noise and Dean quickly stepped in and grabbed Sam's arm to shut him up. Once they settled down, Cas suddenly appeared in the doorway.

"Morning" Dean said shortly but a smile crept over his face nonetheless. Trubel found herself staring at the angel until Nick nudged her lightly, bringing her back to her senses. She shook her head and looked away, doubting she would ever truly wrap her head around what was going on. One by one they sat down for breakfast- Sam forcing Cas to sit because 'yes I know you're a multi-dimensional being and you don't eat but you can still sit'. After the initially uncomfortable silence, Nick finally spoke.

"You know, you guys never actually explained why you're here in Portland"

"There's a demon hanging around here. Nothing too major but it's kicking up trouble" Dean said through half a mouth full of bacon.

"Do you think it killed Sophia?" Nick questioned, hoping to get any information he could out of Dean- he needed all the help with this case that he could get.

"Yeah, that's all fatal damage it's done so far"

"Why would a demon want to kill its host?"

"Who knows? All we know is that Sophia is the only person it kills, no more deaths"

And then silence rolled over the group once more. Eventually, everyone had eaten and after Nick whispering to Trubel that 'no she could ask if Castiel could clear away the plates with his powers, he was an angelic being, not a wizard' Nick told everyone of his plan. Trubel would call over Hank and Bud and stay at the house with Sam and Castiel while he took Dean, Monroe, and Rosalee to the trailer. They all need to learn about the other's world and this was probably the best way to do it. There appeared to be no objections, so Nick called up the other two and agree to meet them at the trailer. He and Dean bid their goodbyes, got in Nick's car, and headed out.

"So, where exactly are you taking me?" Dean asked, slightly cautiously once they were about half way there.

"When I first found out I was a Grimm, my aunt left me a trailer. It's full of books, weapons, and pretty much everything a Grimm needs"

Dean nodded in acknowledgement but didn't say a word. The two of them remained in silence until they reached their destination to see Monroe and Rosalee had already arrived.

"I'm sorry I didn't call you last night, everything was happening all at the same time that I kind of just forgot, " Nick said apologetically once they got out the car and he was met with Monroe's raised eyebrows. The Blutbad said nothing, but a small smile flickered over his lips before he turned to face Dean who was hovering by the entrance to the trailer.

"Dean Winchester, I take it?"

"Yeah," Dean said shortly, unsure of what else to say. Once greetings were made and everyone was finally introduced, Nick summarised what had happened in the last twelve hours to Monroe and Rosalee before opening up the trailer. Dean stepped inside and was instantly taken aback by the volume of books that cluttered the relatively small space. Nick squeezed himself passed Dean and picked up a random book from the shelf.

"These books contain pretty much everything there is to know about every Wesen ever discovered" Nick handed the book to Dean who began flicking through the pages, instantly intrigued.

"So basically, Grimms kill Wesen like hunters kill monsters" Dean drew his eyes back up from the pages.

"Mostly, though some Wesen are on our side. Not that the old Grimms ever knew that. Or at least, they never had the chance to find out"

"So, who's what?"

"Monroe here is a Blutbad and Rosalee is a Fuchsbau. Bud, who's over with Trubel, is an Eisbiber"

"How can you tell who is what?" Dean's eyes drifted back to the pages as he sat on the edge of the bed.

"Like I said before, I can see them when they Woge which they either do voluntarily- meaning even you could see it- or when they do it due to being highly emotional, and that's when only Grimm's like me and Trubel can see them"

"What does it look it?"

"That's what I was planning to show you"

Once Dean looked up, Nick nodded to Rosalee and she stepped towards Dean a little. There was a small pause, then she Woged. Much to everyone's surprise, Dean didn't seem all that freaked out. Monroe then stepped towards Dean and he also Woged, causing Dean to do no more than blink in shock.

"How many Wesen are out there?" Dean questioned, turning to face Nick with an expression of complete curiosity.

"We don't know, millions probably"

"Have you ever seen someone like Cas before?"

"No. And there was no mention of anything like him in any of the books we have either. Maybe other Grimm's powers couldn't see stuff like that, or maybe they just never came across it"

There was a silence as Dean's eyes continued to scan over the pages of the book in his hand until suddenly Dean's cell began to ring. Quickly, he pulled it out of his pocket and answered it to hear his brother's voice.

"We think we've located the demon"

"We're on our way"

"They've found where the demon is hiding," Dean said once the call had ended and he turned back to the others in the trailer. The four of them headed back to the house without a second left to thought.
