I really want an episode of Supernatural with Cas going to Dean and saying, “I have been having strange emotions lately.”
"Uh, ok…you ok?"
"Dean…I think I am developing…feelings…"
"…for your brother."
And then Dean teases Cas for a bit for having a crush on his geeky little brother, but then totally shows him the ropes of flirting; of course, Cas doesn’t really get it, but he’s trying really hard and when he finally manages to go up to Sam and ask him, “Will you go on a date with me?” Sam has to take a minute to pick his jaw up off the floor (because it’s the last thing he ever expected) but it’s so cute that he just kind of says yes out of shock.
But then the date is beautiful and perfect. Cas takes him to a movie that neither of them really care for but they work up the courage to hold hands during it and Cas kisses Sam on the doorstep of the motel and Sam is completely hooked.
