After 9x18, Sam and Dean have a much needed talk about Sam's and Gadreel's words to Dean finally making them admit how they feel about each other. WINCEST

To thank Sam for solving the Zanna murders, Sully tries to give Sam the only thing he's ever wanted: Dean. Wincest.

After two vegetarian restaurants, an almost serious usage of the term "buttercup," and an incident with Dean's mouth pressed against his ear, Sam came to the disorienting conclusion that they were quite possibly dating. Or, more accurately, that Dean was honest-to-god courting him like a modern-day knight in distressed leather armour.

"Man, this pie is awesome," Dean swooned and grinned at his brother, "Seriously, dude, I could kiss you for this - not that I would, of course." Living the life, Sam and Dean had stopped striving for happiness a long time ago. But in truth, they could be good together. And it only takes a Cupid, the Greek god of wine and a marriage counsellor for them to see it. [Wincest]
