So wait, Sam can walk around soulless or possessed by an angel and Cas doesn't notice a thing... but Dean GETS A NEW OWIE ON HIS ARM AND CASTIEL CAN DETECT IT EVEN THROUGH DEANS MANY LAYERS?? *COUGH*DESTIEL*COUGH*
IT’S LIKE HE KNOWS DEAN INSIDE AND OUT SO HE WOULD KNOW IN THE CORE OF HIS CELESTIAL BEING IF THERE WAS JUST A TINY SCRATCH ON DEAN,
(Annoyingly, I think the real reason Cas couldn’t detect Gadreel possessing Sam was because when he was around Sam, Cas was human. Now Cas has angel mojo again he can tell when magic is afoot? But ssssshhhh I like your shipper reason much better. <3 )
ALSO, IMMA WAITING FOR THE FANART IN WHICH CAS STRIPS ALL OF DEAN’S CLOTHES OFF YELLING “DEAN, THERE IS SOMETHING DIFFERENT ABOUT YOU, I NEED TO CHECK WHAT IT IS.” :’)
I was reading s-cornelius’ comment on deangirl’s post on how Sam knows about Dean and Cas, and I just couldn’t stop watching this gif.
It’s Sam’s body language that makes me absolutely sure that he’s figured out what Dean and Cas haven’t—that they’re in love. Because we’ve all seen this kind of body language in tv shows and movies over and over and over, and we’ve seen it in specific circumstances.
This isn’t Sam giving a sitrep about a tactical problem. This is Sammy bracing himself to give his already debilitated brother news he believes might break him.
And I mean literally bracing himself—look at the way he takes a breath and shifts his weight before he speaks. The way he licks his lips after he says, “Listen, Dean,” delaying just a fraction of a second before he tells Dean that Metatron has Cas. Watch how he keeps his facial expression calm and forms the words very carefully, speaking a little slower than he usually does, so that Dean, who’s really still a bit out of it, can clearly see as well as hear what he’s saying.
This is the demeanor of a person saying, “I’m sorry, we’ve done all we can, but you should prepare yourself for the worst,” to someone who may be about to lose the man he loves.
