Sam still isn’t quite used to it.

Don’t get him wrong - after ten years of trying to ignore the romantic tension in the room, it came as a huge relief when Dean and Cas finally got their shit together and… well, got together. But it’s weird sometimes, too. Like today, when it’s the fourth time he’s caught Dean staring at Cas from across the library, totally ignoring the manuscript he’s supposed to be reading, chin propped in his hands. He looks like an eighth grader staring dreamily at his crush from across the cafeteria, and Sam can’t help but chuckle.

“Dude, you are so besotted.”

He hadn’t meant to say it out loud, but Dean is already stirring, tearing his gaze away from Cas and shooting Sam a dirty look.

“What’d you just call me?”

Well, he’s been caught out now. Sam clears his throat.

“Besotted. It means… infatuated. Enamored, smitten.” He pauses, but the last word escapes before he can stop it, a missile built for destruction. “Lovestruck.”

He’s gone too far, Sam knows it immediately. He’s ruined everything. He waits for Dean to sputter out a denial or crack a joke, or worse yet, for his eyes to widen as he starts to panic. He waits for it all to start crashing down.

Instead, Dean surprises him, leaning his cheek against his fist and humming thoughtfully.

“Oh,” he says. And then… that’s it. He nods, already turning away to stare at Cas again, a small smile at the corners of his mouth. “Yeah.”
