of course Blaine knows he spent half of this fic being pounded into in the backseat of a car
#everything you need to know about the relationship between Dean and Cas can be read on Sam’s face in this scene #it’s like someone let Jared read all of the Destiel fanfic in which Sam awkwardly tries not to get in the middle of whatever the hell it is that’s going on between these lovesick idiots THIS time. And he just wishes one of them would make a move or something already because he’s sick of feeling like he’s seated at a junior high school cafeteria table with a bunch of thirteen-year-olds
A hopefully correct interpretation of this scene.
I feel bad for Cas T_T
