Sam watches, frowning deeply as Dan tries to keep his siblings' attention away from what's going on outside. And while Sam himself would love to go out and see what's going on, he stays in place. At least partly because he figures the Ghost wouldn't allow it.

When the parents come back, though, something chill goes up Sam's back. It reminds him too much of the way his dad had been at that last moment, knowing he'd traded his life for Dean's even though Sam hadn't at the time. "What did they do?" he asks the Ghost, turning away from the scene. "Was she a demon of some sort? Did they make a Deal and their ten years are up?"

Yes, he knows from long talks with Dan about the differences in their worlds that the demons where Dan's from don't quite work that same way. But it feels like a Deal come home to roost.
