Sam was too young to remember their older brother. Sam didn't even know they had an older brother. He was only six when their brother had walked out and John had forbidden Dean from talking about him. And every day Dean misses his brother. But Dean can remember every detail about him.

And one day, sat in the bunker with Cas, he sees the news and it all comes rushing back to him. He tries to explain to Sam that he'd been banned from talking about their brother. He explains how he walked out when he was fifteen after an argument. And, while packing to go to New York, he tells them what he remembers about his older, smarter, better-looking brother.

Dean tells them all this as he drives to New York. Cas is sympathetic, Sam is angry, wanting to know why his brother was never talked about again. And then they arrive in New York. Stood right there, outside a shwarma restaurant, is his older brother. The bow is strapped to his back and light is bouncing off his hair. He's smaller than Dean remembers but Dean's grown a hell of a lot. He still looks like an angel but more like a Cas-style angel, one that's Fallen for wondering. He turns his head and there's that look again, the look only his brother can give. Cas suddenly smiles, like everything's just made sense to him and Sam laughs and makes a joke about his height.

And then Dean doesn't remember much else.

His brother reaches up to hug him and Dean wraps his arms round and damn, if it doesn't feel good.

"Dean."

"Clint."

And then, even as Clint's told what's happening with Michael and Lucifer and his eyes narrow to slits Dean knows that while nothing will be normal again they're going up against three Winchesters, an angel, a super-soldier, a super-spy, a Norse god, a billionaire genius and an enormous green rage monster. This is going to be good.
