Sastiel “I’ve accidentally liked one of you Facebook photos because my friend was tagged and now I’ve been stalking for profile for the past hour” AU
IT WASN’T THAT Sam hated Castiel Osteguna - far from it, if he was being completely honest, though he took care not to let on to anyone who might repeat it - but ever since their rather disastrous first meeting Sam had been convinced that Castiel hated him, which rather put a damper on any inclinations Sam might have had to further contact between them other than what was unavoidable due to their mutual affection for Dean... and Dean swore up and down that the affection Castiel had for him was just friendship which, on the one hand, relieved Sam’s mind because he didn’t have to worry about ever walking in on the two of them in flagrante delicto one of these days, but on the other hand it didn’t allow Sam that safety net of “Dean’s; off limits” to keep his traitorous heart from developing the world’s most embarrassing and gigantic crush on Castiel.
So avoidant was he of any unnecessary contact between them, that Sam hadn’t even known Castiel knew what Facebook even was, much less that he had an account, until he had Liked a picture tagged with Dean’s user name showing his brother obviously drunk with a tie around his head like a bandana and trying to “dance” on a street sign like it was a stripper pole, only realizing afterwards that the user who had posted it was Castiel; too late to take back the Like even if that was Sam’s style - which it wasn’t - and so Sam didn’t really think anyone could blame him for kinda sorta maybe stalking the older man’s profile, drinking in this unexpected glimpse of a Castiel that Sam never got to see told in snapshots and pithy political posts spliced together with random memes. So caught up was he in his new discovery of this whole new facet of his crush that only made Sam fall even harder, that he nearly missed it when Castiel’s profile page updated with a new status: “Quietly freaking out, best friend’s hot brother liked my photo, what do I do??”
