Re: the last episode title: If Dean doesn't attempt seriously to kill Sam in the last episode of the season, I'll be shocked. Crowley and Cas's deaths, they've laid the breadcrumbs for, although whether those stick, who knows?

So we finally get acknowledgement that the Mark of Cain is going to go somewhere with the brother-killing. I can't help wondering if the earlier mention of Adam in the season was some sort of breadcrumb, but that's probably giving Carver too much credit. Still, that might be one way to tie up some issues. Open up Lucy's cage, kill Adam to fulfill the Cain side of things. If Michael was free, he might be able to clean up the whole Heaven issue. And finally taking out Lucifer for good could wrap up their 11th and (hopefully) final season, and let the boys go out in a blaze of glory. We've already seen that Carver likes to repeat story lines; I wouldn't put it past him to borrow from a better season to repeat.

Couldn't help noticing the hints at the beginning of the episode that indicate that Dean is not sleeping -- it's early morning, and he's had enough time to clean the engine until it's gleaming AND find a case before Sam even wakes up. The Mark of Cain is still definitely very much in play.

It seems very likely to me that Sam is going to be drinking demon blood, if you listen to what Dean says that in that preview: "I got a hell of a lot more running through me than just demon juice." "There ain't much difference from what I turned into from what you already are." "I know what you did when you went looking for me. And I know how far you went."
