I loved this. That's the conversation I really want to see, but I wonder if Sam ever really will tell Dean he was dead for more than three months.

And this bit was heartbreaking: And he’d handled the pain like a man who knew that no help would be coming. Dean felt sick at the realization: Sam had forgotten that there was any help left to come. He’d forgotten that he wasn’t completely and utterly alone. God, what must he have done when he was hunting, with no one?
