It was good to see Dean laugh. Really laugh. Like the old days. He couldn't remember the last time he'd seen Dean laugh like he meant it. The sight made Sam's heart clench. It was so, so good. Addictive too. Dean's laughing caused Sam to laugh.

They should pretend the whole incident never happened and block it out of their minds. But now Sam had had a taste of it, could he give it up?

"Dean... we need to think about this... I mean, seriously think about it..." The whole illegal brotherly incest part aside it made logical sense. They were both hunters, they both knew the life and the risks, they could depend on each other, and were always on the road together. But, could they make it work in the long run? Really?
