Sam and Dean will be brothers fighting to save people and hunt things to the bitter end. And it's good to see that among all the hunts and the battle with the Darkness, the two can have a solid sit down and just be brothers.
The Winchester brothers are definitely having a serious conversation. Maybe Dean has told Sam about his connection with the Darkness. Maybe the two have come up with a plan to even stop it. Or maybe they just can't decide where to get lunch next.
Sam and Dean, don't look now, but you've got someone hanging out in the backseat of the Impala! This guy is either their latest monster or the one who's going to lead them to it. But will he be correcting Dean's driving the whole time?
So what snarky or witty comment is Dean going to say during this moment? It looks like he and Sam have worked with the police on their latest case, or maybe they are just getting the first info before they really dive in.
