A/N I've had this idea off and on since I found Grimm and then found Teen Wolf. It just seems like an awesome blending to bring the two of them together.

I'm not sure where I am going with this. I just had this idea and it wouldn't die and I read another fic on Ao3 that was the first crossover of these fandoms and my idea just got bigger in my mind. So here it is.

Canon for Teen Wolf up to S2 E2 and Mid-somewhere season 1 for Grimm.

I have a beta, Anna, I'm re-editing the first four chapters (nothing big has changed, just grammar things).

Enjoy the show.

A Grimm Visit

It was the Isaac Lahey case that was the straw that broke the camel's back. Finding Stiles in the room with a knocked out guy, who had a broken arrow in his leg dressed in a deputy's uniform, while the door to the isolated jail cell was busted open, was what sent Sheriff Stilinski over the edge. It didn't matter the story that Stiles came up with on the fly about what happened. Stiles was lying and they both knew it; but the truth was probably some conglomeration of events that would be too unbelievable to even think about accepting as the truth and so he just officially accepted it and went on.

Except he didn't.

It was eating at him, at the back of his mind, all of the things that Stiles has been involved with in the past couple of months. Lydia's mauling, the hunt at the high school, Derek Hale being a serial killer and then not and back again, twice, not to mention the whole ditching the first lacrosse game that Stiles would be first string in. He still didn't understand that.

Nothing fit. Some other parent would think it was just a teenager acting out, but he wasn't some other parent. He was Stiles Stilinski's father and he was also the Sheriff of Beacon Hills. He knew somewhere in his gut that all of these events were connected to each other. He didn't have any real idea how they were he just knew they were. Call it a cop's intuition but he knew Stiles and his friends were deep in the mess with the bodies.

It was his father's intuition that was telling him that Stiles was going to be in danger, if he wasn't already. It was this itch at the back of his throat that he picked up since the high school hunt incident. He still didn't know what to believe about that. Stiles and Scott told him it was Derek Hale but Derek Hale was cleared of everything. In addition to fabrication of a statement the damage to the school didn't really fit with what a single human could do. Not to mention there was still no explanation for why the boys and their friends were being chased throughout the school in the middle of the night.

Then there was the enigma wrapped in a riddle of how Katherine Argent ended up in Hale's burnt-out childhood home with her throat torn out and Derek Hale's uncle's burned body towards the front of house by the woods. It was still something that could not be explained fully. Not with the physical evidence they obtained. How did Kate Argent's throat get ripped out like that? The amount of force concentrated on the windpipe to be able to physically rip it out without damaging any other part of the neck is something that no normal human could possibly do. Not with just their fingers, which is what the medical examiner said was the culprit.

The idea that Peter Hale was somehow able to do it was just too preposterous to even think about accepting but they had no other suspects and the physical evidence that they found seemed to lead to that direction.

Some of the deputies think he was probably hopped up on some drugs like PCP or those "bath salts" that cause excited delirium. The video of some of those arrests still send chills down his spine. But preliminary reports do not show anything of that sort in the blood from Peter Hale's burnt body. In addition, is the knowledge that, before disappearing from his hospital room and winding up somehow killing Argent and being burnt to death, he was in a catatonic state for six years. His muscles should have shown signs of entropy but there was no evidence of that either.

Nothing was making sense. It was still early in the investigation and there was still the forensics and testing to be done but Sheriff Stilinski knew nothing would change. Officially Argent will take the rap for all of the mysterious animal attacks and Peter Hale will take the rap for killing Argent. As for how he burnt to death the closest that another can figure is self-immolation, basically he killed himself.

Why and how are still to be debated, but officially everything is wrapped up in a neat little bow and he knows that the case will be closed.

What really gets to him is that he knows in some fashion that Stiles was involved in that one as well. The fact that Argent's niece is or was dating Scott only cements that factor. Officially he can't prove anything, yet.

Clawing from inside of him is this feeling that one day he is going to come across a body that Stiles or his friends put there and he knows he will have to follow the law and do his job. What haunts him though is the deeper set intuition that tells him that Stiles might be one of those bodies himself; his thirst for adventure going too far and being involved in something at the wrong place at the wrong time.

He already lost his wife he does not want to lose his only child as well. Sheriff Stilinski doesn't think he would ever be able to fully recover if he lost Stiles as well. He knows that Stiles feels the same.

Which is why when the call came that Portland had a case that might be tied to a cold case of theirs, that Sheriff Stilinski volunteered to take the evidence and personally work with the officer in charge of the case. It is rare for the Sheriff himself or herself to go to another city just to exchange information but Sheriff Stilinski was the one in charge of the case and knew the most about it. So it was not without precedent to go there since the Portland PD detective in charge of the case in question would not be coming to Beacon Hills.

Sheriff Stilinski felt it was something that his son would call kismet. Here he was looking for a reason to get Stiles out of Beacon Hills where bodies now seem to be dropping every week by strange and unexplained animal attacks and Portland PD calls up looking for information on a cold case that the Sheriff had been in charge of when he was a deputy.

Whatever awaited them in Portland could not be worse than what was going on in Beacon Hills. Just a few days with his son, out of town, doing trivial information exchange is all he needs to get recharged and handle what seems to be becoming a normal acquaintance in his town, more bodies.
