I think it's shorthand for "being brothers" really. I only say this is canon because Dean simply sat with him, and Sam's head wound up on his shoulder, which I can completely imagine happening in the past if not so much now.
BUT under these circumstances, I thought it was right on.

IJS. Total cuddling. And then Dean put his head on Sam.
CUDDLERS.
Maybe I skimmed that part. Heh.
Jensen! Marry me! He got almost all those questions right.
The heavy sigh and "Jello" were pretty priceless, too.
Who was the interview by, again? Slash fiction? Really?
(Jensen! Call me!)
This, on the other hand, seems weird. The CW has renewed the show repeatedly, and I just saw chatter somewhere about a possible eighth season. I think for their position in the market, they're probably fairly happy with the ratings, and the fanbase, right?
