There's a baby, but neither Sam nor Dean looks very pleased at its appearance. Word is Darkness will take on the form of a specific entity, and a she to boot. Could it start out as a baby, and this one in particular? That wouldn't be a reason to smile.

It's Sam! How we've missed you, Sam. The brothers will be up against the Darkness, a pre-biblical foe who was defeated by God years ago. Sam is shown reaching out to God in the trailer. Can he be of help again? You'd think he might be angry the Winchesters released Darkness after it's already been banished.

Crowley likes to talk to young men in pairs, apparently. When the Winchester brothers aren't around, he'll find another pair of young men to take their place! What do you think he knows about the Darkness? Was she ever mentioned in his social circles?
Added:
Nothing really gets Crowley down, not even spells that his mother tries to cast to bury his ass. Not that I mind, he's a favorite. The trailer teases he's back to his old fun self, too!
Added:
Castiel on a rampage? Is that what we're going to see? I have no idea what's next for this poor angel, but something tells me we're not going to like the direction his story is heading.
Added:
Castiel is battered and bloodied and perhaps blind? Things do not look good for this fallen angel, and if the trailer is any indication, he's out for even more blood.
Added:
Rowena is conjuring up some magic. Has she figured out how to get rid of the Mark of Cain? Dang. She's still at it. On the plus side, she's on the Winchester's team, right? RIGHT?!?!
Added:
Castiel seems to be pondering something. Is it a deal with Crowley? Or is he wondering where Sam and Dean are? We're guessing that he didn't imagine Crowley being so drastic with his mutha. Like, "Huh, I sure didn't see that one coming."
Added:
The King of Hell is back to his old evil self. But what's his plan with Rowena and Castiel? He's looking rather chipper. Whatever his plan is, it must be making him feel confident. Long live the King of Hell!
Added:
Crowley is definitely throwing out one of his clever quips at Castiel. The King of Hell is back! It's our hope he's saying something about how easy it is to say goodbye to mothers and not to stand in his way while he drags her off into the ether...
Added:
Crowley looks like he's come for Rowena. Will Castiel stand in his way? More importantly, why would Castiel stand in his way when all we want is for anyone to please drag Rowena away??
Added:
Oh no! It looks like something has got Sam down. Is he hurt? Is it Death? Even Dean looks concerned. What the hell? Did Death attempt a death blow with that huge scythe? Didn't we already determine that wasn't an option?!

You betrayed me? No one in the history of torture's been tortured with torture like the torture you'll be tortured with.

Just because you're blood doesn't mean you're family. You have to earn it.
