(you liked for a kiss, for sam i assume?) Eddy watches him with fascination, but it is his lips that his eyes are captivated by. The words he's saying becomes unclear as he stops listening. Instead of letting Sam go on and on, he leans in and kisses him to shut him up.
The situation is only mildly annoying. Sam was halfway through an exhaustive rundown of shapeshifter lore—which Dean insists no one cares about—when he realized Eddy wasn't listening anymore. Not even pretending to.
He considered pulling one of his usual tricks of throwing in a fake fact just to see if Eddy would repeat it later, but instead, he just stopped talking. The staring was mutual then, though not exactly eye-to-eye.
He's a second away from asking what, exactly, is so fascinating when Eddy leans in and kisses him.
He doesn't pull away. In fact, he leans into it a little, but it ends sooner than he wants it to, and Sam blinks, visibly short-circuited.
"Uh--right. That's… That's one way to ask me to shut up."
He tries to smirk, but it comes out more like a nervous twitch, gaze dropping to Eddy's mouth for half a second too long before travelling back up.
"You know, there are politer options, like... uh… a 'shhh'?"
