The moment Dean said the words “couples-only event,” you knew you were in trouble.

Sam and Dean had brought you in for a case involving a ritzy mansion dinner where couples were mysteriously going missing. Dean, of course, suggested you and Sam go in as bait.

But Sam said no.

And now, here you were standing on the grand marble staircase of some rich guy’s cursed estate, hand in hand with Jackson, a tall, annoyingly charming hunter you’d worked with once or twice before.

Sam watched from across the room in a tux that made him look unfairly good.

“Relax,” Jackson whispered to you as you both took your seats at the candlelit dinner table. “You’re squeezing my hand like you’re holding holy water.”

You laughed quietly, forcing your shoulders to loosen. “Sorry. Didn’t think Sam would actually say no.”

Jackson smirked. “Maybe he’s not into you like you thought.”

You didn’t reply. But you didn’t like that answer.

Across the room, Sam adjusted his tie and narrowed his eyes.

You were smiling. At him.

He clenched his jaw as Jackson leaned in closer to whisper something in your ear. You laughed again. Sam looked down at the wine glass in his hand like it had personally betrayed him.

Dean sipped his whiskey, elbowed Sam, and tilted his head toward you.

“Wow. Look at that. She’s smiling. Laughing. Having a good time. Y’know, like normal people do when they’re not being emotionally repressed robots.” Dean says with a smug expression.

“She’s undercover.” Sam mutters, standing stiff.

“Sure she is. And Jackson’s hand on her lower back? Definitely for the mission.”

Sam shot him a glare.

Dean just shrugged, unbothered as ever.

“Hey man, you had your shot. Said no. Now you get to stand here like an uptight ex-boyfriend watching his girl move on.” Dean says drinking his wine.

Sam didn’t respond, but Dean could practically see the steam rising off him.

“Bet you’re regretting that ‘I don’t think it’s a good idea’ crap now, huh?” Deans says with a smug expression patting Sam’s shoulder and going for more wine.
