I have a feeling that Dean finally caught on to the idea that maybe, just maybe John was making some really bad choices when raising his boys. And that maybe the gaping hole in his heart partly stems from being denied having a life of his own.

Dean and Cas deserve each other, seriously they both need more love in their lives
A thousand times yes to this. My wish for season 6 goes like this: Sam's missing, and Dean and Cas team up to find him, roadtripping all across the country, growing closer all the time... ♥

Hee! The slash will get to everyone, no matter how long it takes. ;p
