"Sebastian, how long have you worked at the hospital again?" Blaine asks as he spears a piece of salmon with his fork.

"About four years now," Sebastian says, and then he doesn't elaborate.

Blaine doesn't know why this feels so awkward. The conversation has felt stilted the whole evening, he's usually so good at connecting with people but there's just something about Sebastian, about this whole dinner together, that seems off. Uncomfortable.

He wishes he could place it.

"Right, so you must have been there already when Kurt started," Blaine comments, taking the salmon on his fork into his mouth.

"Yeah, I was," Sebastian replies. "Couldn't stand him at first, if I'm being honest," he adds with a chuckle.

"Don't worry, the feeling was mutual," Kurt shoots back, a grin tugging at the corner of his lips. "I used to plan my breaks so I wouldn't have to see you in the break room."

"And look at you now. If I didn't know any better I'd think you were sitting in the break room waiting for me to take my breaks, just so you get to see my face."

Blaine knows Kurt. He knows his mannerisms, his tells. He knows the light blush colouring Kurt's cheeks means Sebastian must not be entirely wrong.

"You wish," is Kurt's reply. "More like you're stalking me and trying not to get caught. Terrible job, by the way. It's obvious."

"Well shit, I guess you're on to me," Sebastian says with a laugh, crossing his arms across his chest and looking straight at Kurt. "You can't really blame me though, can you?"

Kurt coughs a little, a surprised sound, and his cheeks grow a little redder. He takes a sip of his wine before he speaks again, a compliment to Blaine on the lovely dinner he's prepared.

He thinks he can place it, now.

He wishes he couldn't.
