Teen Wolf Fanwork Finders

Hi everyone! I only remember a few setails of this one so this will be a bit vague. It's either a time travel fic or one where Stiles travles to an alterate timeline.Where he goes, he's not friends with Scott and is being blackmailed by a goth girl (because of porn???) and maybe hangs out with some bullies or is a bully himself but is forced to act like that. I think that the Stiles who body swaps with himself is much more BAMF and good at magic and sets things right again. I seem to remember that he sends the bullies gifts of raw meat that won't stop bleeding. I'm not sure if there was a pairing or not. it's short and not very detailed. Thanks in advance to anyone who recognises this ^_^

Hi everyone. I'm looking for a fic that I read a few years ago. I know the basic outline as well as some specific details but it's not enough to find it through google or my history. I'll put as much detail as I can and hope someone recognises it. I'm pretty sure it's quite long, either a long one-shot or a few long chapters, no more than 10 though. I can't remember if it was on ff.net or ao3 though, more likely to be ao3. Don't think it was nsfw, more focused on the coroporate espoinage andmurder mystery side as well as the budding romance bewteen Stiles and Derek.

Derek work for a business/is the CEO of a business that his family created. Probably named "Hale ____". His parents/family died in an accident at a factory (?) that they own. I think it's something to do with chemical engineering but not 100% sure. Stiles is hired as a receptionist/assisstant/intern of some kind, but is secretly working for the Argent's. He feels guilty about the corporate espionage, I think they're trying to get him to get into the company's computers to steal research/products or delete evidence of something. Maybe the Argent's consistently release a product that's based on Hale research before they can, but there's no proof that their info is stolen.
There's a really big plot point about Derek and Stiles trying to solve his parents murder, which Kate and Gerard did. The accident that killed then wasn't an accident, silver powder (?) was used as a flammable substance that exploded. At the end of the fic, Stiles and Derek go to the Argent paper archives building to get the evidence they need, and the Argent's set the place on fire but Stiles figures out that ionised silver powder (??) is flame-retardant instead of explosive and they survive. Stile's Dad and the police are outside ready to arrest the guilty Argent's. I think that Allison and Chris are good though.

I anyone recognises this I'd be very grateful, even if it's been deleted. I might be overlooking a really obvious/well known fic but for the life of me I can't find it. Thank you in advance to everyone who looks at this.
