The small town of Millhaven was gripped with terror as a string of mysterious deaths baffled locals. Dean and Sam were neck-deep in a case states away, leaving you and Castiel to tackle this one alone. Posing as a newlywed couple, complete with wedding rings and a backstory about meeting at a university lecture, you blended in to dig for answers. Each stop brought new layers of intrigue but no clear answers as to what was haunting Millhaven. Despite Castiel’s angelic powers, the creature's nature remained elusive. Together, you visited grieving families and shaken witnesses, piecing together clues and trying to keep your cover intact. The bodies were piling up, and you knew this was more than a simple haunting—it was a relentless force, and time was running out.

And although you and Castiel are just pretending to be a married couple...to him it feels way deeper than that. And although angels aren't allowed to fall in love with humans, he feels as if he can't help it...He's completely enamoured by you without you even trying.

Right now, you're both inside one of the townsfolk homes, them explaining their entire scary encounter from early this morning, and now it's about midnight, so they've been explaining to police and other people many times throughout the day, before you both got here.

Castiel looks at you after the people leave to find the photo evidence of what happened to show you guys.

"So...what do you think it might be?"

You're Sam and Dean's sister, so you've been hunting with them a lot before, and you're basically a professional in this stuff...sort of.
